Does anybody know how to automatically expand a UI-grid that is performing a grouping? I need the grid to open up and start up with it being completely expanded.
Their API and Tutorial reference doesn't explain explicitly enough for me to understand.
My HTML div
<code>
<div id="grid1" ui-grid="resultsGrid" class="myGrid" ui-grid-grouping></div>
</code>
My Javascript
$scope.resultsGrid = {
,columnDefs: [
{ field:'PhoneNum', name:'Phone'},
{ field:'Extension', name:'Extension'},
{ name:'FirstName'},
{ field:'DeptDesc', grouping: {groupPriority: 0}}
]
,onRegisterApi: function(gridApi)
{
$scope.gridApi = gridApi;
}
}
you just need to add
//expand all rows when loading the grid, otherwise it will only display the totals only
$scope.gridApi.grid.registerDataChangeCallback(function() {
$scope.gridApi.treeBase.expandAllRows();
});
in your onRegisterApi: function(gridApi)that should be updated like this onRegisterApi: function(gridApi) so your function will be like this
$scope.resultsGrid.onRegisterApi = function(gridApi) {
//set gridApi on scope
$scope.gridApi = gridApi;
//expand all rows when loading the grid, otherwise it will only display the totals only
$scope.gridApi.grid.registerDataChangeCallback(function() {
$scope.gridApi.treeBase.expandAllRows();
});
};
or you can add botton to expand data like shown in this plunker
My Module - I had to add ui.gridl.selection
<pre>
<code>
angular.module('ddApp',['ngRoute','ngSanitize','ngCookies','ngResource','ui.grid.selection'])
</code>
</pre>
My Controller - Amongh the other Dependency Injected items, I also had to add $timeout
<pre>
<code>
.controller('myCtrl', function(`$`timeout)){}
</code>
</pre>
<pre>
<code>
$timeout(function(){
if($scope.gridApi.grouping.expandAllRows){
$scope.gridApi.grouping.expandAllRows();
}
});
</code>
</pre>
The closest analogy would the selection tutorial, in which we select the first row after the data finishes loading: http://ui-grid.info/docs/#/tutorial/210_selection
$http.get('/data/500_complex.json')
.success(function(data) {
$scope.gridOptions.data = data;
$timeout(function() {
if($scope.gridApi.selection.selectRow){
$scope.gridApi.selection.selectRow($scope.gridOptions.data[0]);
}
});
});
The key understanding is that you can't select (or expand) data that hasn't been loaded yet. So you wait for the data to return from $http, then you give it to the grid, and you wait for 1 digest cycle for the grid to ingest the data and render it - this is what the $timeout does. Then you can call the api to select (or in your case, expand) the data.
So for you, you'd probably have:
$http.get('/data/500_complex.json')
.success(function(data) {
$scope.gridOptions.data = data;
$timeout(function() {
if($scope.gridApi.grouping.expandAllRows){
$scope.gridApi.grouping.expandAllRows();
}
});
});
If you're on the latest unstable, that call will change to $scope.gridApi.treeBase.expandAllRows.

I've recently started looking into the nice ember-resources library because I came to the point my data fetching routine required some reactivity. Since we tend to use the ember-concurrency tasks in our project I wanted to follow the common pattern and I was happy to realise that ember-resources support ember-concurrency tasks out of the box.
Now i've got a dependant tracked property which is basically a timer and it's being updated every minute. What I want to do is to be able to run my task say every two minutes. The question is how to achieve this?
Here goes my pseudo-code:
// that's my component
#restartableTask
*fetchFeed() {
yield timeout(1);
return yield this.store.queryRecord('item', {...});
}
get currentTime() {
// this one returns a tracked variable which is updated every minute
}
feedResource = trackedTask(this, this.fetchFeed, () => [this.currentTime]);
// this is the corresponding hbs
{{#if this.feedResource.isRunning}}
<LoadingSpinner />
{{else}}
{{this.feedResource.value}}
{{/if}}
what I want to do is basically
get every2Minutes() {
return Math.trunc(this.currentTime.second() / 2)
}
feedResource = trackedTask(this, this.fetchFeed, () => [this.every2Minutes]);
but it's still run on every minute. I've tried using the #cached attribute and a custom cache solution but it didn't help - despite that the cache gave me the correct value, i.e. only even ones, the task was still fired every minute. Can I tell the trackedTask to not fire if the dependency wasn't changed?
👋 Hi, I'm the author of ember-resources! glad you're having fun with the library!
this one returns a tracked variable which is updated every minute
While this is clever, if the variable isn't used in the task, it "feels weird". I don't have better words for this. 🙃
But, to directly answer your question, I'd define currentTime like this:
const ClockEveryOtherMinute = resource(({ on }) => {
let time = cell(new Date());
let interval = setInterval(
() => time.current = new Date(),
2 * 60 * 1000, // 2 minutes
);
on.cleanup(() => clearInterval(interval));
return () => time.current;
});
class Foo {
// `#use` is required when a resource returns a single value
#use currentTime = ClockEveryOtherMinute;
feedResource = trackedTask(this, this.fetchFeed, () => [this.currentTime]);
// ...etc
}
Here is an interactive demo of something very similar
However, I think there may be a more ergonomic way --
In a scenario where you want recurring behavior, there are a couple approaches you could take:
invoke the task once and use a while loop to do something periodically
use a constructor/destructor combo with setInterval
These are somewhat separate from the trackedTask helper utility, as the trackedTask helper utility "only" does lazy invocation of the .perform method on a task when a property on the TaskInstance would be accessed. So... I'm not actually sure if your getter's return would be updated if the task is re-performed every couple minutes manually. I'm maybe.. 60% sure it would? (this is something I don't have tests for).
Anywho back to the options:
invoke the task once
class Foo extends Component {
#tracked items;
#task
*fetchFeed() {
yield timeout(1);
while(true) {
this.items = yield this.store.queryRecord('item', {...});
yield timeout(1000 * 60 * 2); // 2 minutes
}
}
get hasItems() {
return Boolean(this.items?.length);
}
}
// this is the corresponding hbs
{{#if this.hasItems}}
{{this.items}}
{{else}}
<LoadingSpinner />
{{/if}}
using setInterval
import { registerDestructor } from '#ember/destroyable';
class Foo extends Component {
#tracked items;
constructor(owner, args) {
super(owner, args);
let interval = setInterval(() => {
if (isDestroyed(this) || isDestroying(this)) return;
this.fetchFeed.perform();
}, 2 * 60 * 1000);
registerDestructor(this, () => {
clearTimeout(interval);
});
// initial perform
this.fetchFeed.perform();
}
#task
*fetchFeed() {
yield timeout(1);
return yield this.store.queryRecord('item', {...});
}
get hasItems() {
return Boolean(this.fetchFeed.lastSuccessful?.value?.length);
}
}
// this is the corresponding hbs
{{#if this.hasItems}}
{{this.fetchFeed.lastSuccessful.value}}
{{else}}
<LoadingSpinner />
{{/if}}
A "do something every 2 minutes API"
I'm 🤷♂️ on this approach, but for completeness, it's probably reasonable to know that it's possible (I'm going to hand-wave over the implementation, as that could be other stack-overflow questions):
const doEveryTwoMinutes = resourceFactory((callback) => {
// ...
return resource(({ on }) => {
// ...
});
});
class Foo extends Component {
#use feed = doEveryTwoMinutes(() => {
return this.fetchFeed.perform(); // returns a task
});
#task
*fetchFeed() {
yield timeout(1);
return yield this.store.queryRecord('item', {...});
}
get hasItems() {
return Boolean(this.feed.length);
}
}
// this is the corresponding hbs
{{#if this.hasItems}}
{{this.feed}}
{{else}}
<LoadingSpinner />
{{/if}}
(no trackedTask needed, we rely on the internal tracked-state of a TaskInstance)
Why do these approaches not need trackedTask?
because we have "events" that we know about that cause the task to be performed -- and ember-concurrency is really good at being "an event handler", of sorts -- whereas ember-resources is more about deriving data (maybe eventually), with cleanup.
I have read some article about state change listener, As I am a very beginner to the svelte environment I can't figure out what is the most efficient way to listen to the state change.
Let us take state variable as X and Y
Method 1:
$: if (X||Y) {
console.log("yes");
}
Method 2:
Use a combination of afterUpdate and onDestroy
REPL: https://svelte.dev/repl/300c16ee38af49e98261eef02a9b04a8?version=3.38.2
import { afterUpdate, onDestroy } from 'svelte';
export function useEffect(cb, deps) {
let cleanup;
function apply() {
if (cleanup) cleanup();
cleanup = cb();
}
if (deps) {
let values = [];
afterUpdate(() => {
const new_values = deps();
if (new_values.some((value, i) => value !== values[i])) {
apply();
values = new_values;
}
});
} else {
// no deps = always run
afterUpdate(apply);
}
onDestroy(() => {
if (cleanup) cleanup();
});
}
Method 3:
Use writable and subscribe
<script>
import { writable } from 'svelte/store';
const X = writable(0);
const Y = writable(0);
X.subscribe(value => {
console.log("X was changed", value);
});
Y.subscribe(value => {
console.log("Y was changed", value);
});
</script>
<button on:click={(e)=>{
X.update((val)=>val++)
}}>Change X</button>
<button on:click={(e)=>{
Y.update((val)=>val++)
}}>Change Y</button>
Reactive statements
Svelte does not have an equivalent of useEffect. Instead, Svelte has reactive statements.
// Svelte
// doubled will always be twice of single. If single updates, doubled will run again.
$: doubled = single * 2
// equivalent to this React
let single = 0
const [doubled, setDoubled] = useState(single * 2)
useEffect(() => {
setDoubled(single * 2)
}, [single])
This may seem like magic, since you don't define dependencies or teardown functions, but Svelte takes care of all that under the hood. Svelte is smart enough to figure out the dependencies and only run each reactive statement as needed.
So if you want to run a callback every time a value updates, you can simply do this.
<script>
let value = ''
$: console.log(value)
</script>
<input type='text' name='name' bind:value />
In short, this will console log the value of the input every time the input's value changes.
Recreating your suggestions
Method 1
That's about as concise as you can go, and is my go-to means of listening to state changes unless I need something more complex.
$: if(x || y) console.log('yes')
Though note that there may be a subtle bug here. If x or y were both truthy then turn falsy (e.g., they both became empty strings), this statement will not run.
Method 2
Here, you basically recreated React's useEffect. This works, but you can simplify the implementation in your REPL a lot using reactive statements.
<script>
let count = 1;
$: console.log(count)
</script>
<input type="number" bind:value={count}>
Method 3
Stores are great for passing data between components without using props or context. Check out this answer for more: https://stackoverflow.com/a/67681054/11506995
In this case, though, we can simplify everything using regular reactive context (again).
<script>
let x = 0
let y = 0
$: console.log('x was changed', x)
$: console.log('y was changed', y)
</script>
<button on:click={() => x++}>Change x</button>
<button on:click={() => y++}>Change x</button>
I also have a detailed answer of comparing React's context/useEffect with Svelte's context/stores/reactive statements in Understanding Context in Svelte (convert from React Context)
https://stackoverflow.com/a/67681054/11506995
How about this?
<script>
let count = 0;
$: doubled = (() => {
return count * 2
})()
function handleClick() {
count += 1;
}
</script>
<button on:click={handleClick}>
Clicked {count} {count === 1 ? 'time' : 'times'}
</button>
<p>{count} doubled is {doubled}</p>
I am hoping someone more knowledgeable here can point out what the problem is.
I am making a custom menu for Drupal7 for a particular theme I am working on, which is using the menu_views module. Everything works pretty nicely until I pass the view menu entry over to menu_views to parse, in which case drupal adds a broken <div class=">...</div> around the parent UL element of the view menu.. I have gone through the code and don't see how this is even happening.. If I comment out the call to the view parsing, then it doesn't add this DIV, but that view parsing shouldnt' be touching the parent UL element?
Here is how the HTML is output:
<ul class="sub-menu collapse" id="parent_">
<div class="> <li class=" first=" " expanded=" " active-trail "=" ">Por nome
<ul class="menu-content collapsed in " id=" ">
<div class="view view-nameofview view-id-nameofview etc ">
<div class="view-content ">
<div class="item-list ">
<ul class="views-summary ">
<li>Á
</li>
</ul>
</div>
</div>
</div>
</ul>
</div>
</ul>
Here is the template code that causes this:
function bstheme_menu_link__main_menu($variables) {
$element = $variables['element'];
// resolve conflict with menu_views module
if (module_exists('menu_views') && $element['#href'] == '<view>') {
return _bstheme_menu_views_menu_link($variables); //<<<< IF I COMMENT OUT THIS THE OUTPUT IS FINE
}
static $item_id = 0;
// Add an ID for easy identifying in jquery and such
$element['#attributes']['id'] = 'menu_'.str_replace(' ', '_',strtolower($element['#title']));
if(!empty($element['#original_link']['menu_name']) && $element['#original_link']['menu_name'] == 'main-menu'){
if($element['#original_link']['has_children'] == 1){
$element['#attributes']['data-target'] = "jquery_updates_this";
$element['#attributes']['data-toggle'] = "collapse";
}
// add class parent and remove leaf
$classes_count = count($element['#attributes']['class']);
for($i=0;$i<$classes_count;++$i){
if($element['#attributes']['class'][$i] == 'expanded'){
//$element['#attributes']['class'][$i] = 'collapse';
}
if($element['#original_link']['plid'] == 0){
if($element['#attributes']['class'][$i] == 'leaf'){
unset($element['#attributes']['class'][$i]);
}
}
else{
if($element['#attributes']['class'][$i] == 'leaf'){
$element['#attributes']['class'][$i] = '';
}
}
}
}
// code to add a span item for the glythicons
$switch = $element['#original_link']['has_children'];
$element['#localized_options']['html'] = TRUE;
if($switch == 1) {
$linktext = $element['#title'] . '<span class="arrow"></span>';
} else {
$linktext = $element['#title'];
}
// if there's a submenu, send the parsing to the custom function instead of the main one to wrap different classes
if ($element['#below']) {
foreach ($element['#below'] as $key => $val) {
if (is_numeric($key)) {
$element['#below'][$key]['#theme'] = 'menu_link__main_menu_inner'; // 2 lavel
}
}
$element['#below']['#theme_wrappers'][0] = 'menu_tree__main_menu_inner'; // 2 lavel
$sub_menu = drupal_render($element['#below']);
$element['#attributes']['class'][] = 'menu-toggle';
}
//$sub_menu = $element['#below'] ? drupal_render($element['#below']) : '';
$output = l($linktext, $element['#href'], $element['#localized_options']);
return '<li' . drupal_attributes($element['#attributes']) . '>' . $output . $sub_menu . '</li>'."\n";
}
function _bstheme_menu_views_menu_link(&$variables) {
// Only intercept if this menu link is a view.
$view = _menu_views_replace_menu_item($variables['element']);// <<< MENU VIEWS PARSING
if ($view !== FALSE) {
if (!empty($view)) {
$sub_menu = '';
if ($variables['element']['#below']) {
$sub_menu = render($variables['element']['#below']);
}
return '' . $view . $sub_menu . "\n"; // <<< RETURN PATH
}
return '';
}
return theme('menu_views_menu_link_default', $variables);
}
Any pointers on how to troubleshoot something like this, or if someone has encountered this problem before and has a solution, would be greatly helpful!
From your code, it's apparent you're using Drupal 7.
First things first, you may want to enable theme debug mode. This allows for you to see where the theming function that caused your
You can do so by putting the following line in your settings.php file
$conf['theme_debug'] = TRUE;
Flush your caches after you make this change.
You will now have debug code output to your Drupal HTML source, when you view the site's source. An example of the type of output is shown below:
<!-- THEME DEBUG -->
<!-- CALL: theme('page') -->
<!-- FILE NAME SUGGESTIONS:
x page--front.tpl.php
* page--node.tpl.php
* page.tpl.php
-->
With this debug, you should be able to see exactly which theme functions run, in which order, and by working through them from start to finish, you should be able to determine between which theme is responsible.
At this point, if you want to keep Drupal-best-practices, copy the file name suggestion from the debug output to a folder inside your theme folder. I usually put all template overrides in a sub-directory inside it.
In the case above, if it was page.tpl.php, I'd copy it to /themes/mytheme/templates/, and go hack on it to see whether the offending div is being generated there.
Best of luck, and if you hit a stuck end, I'd be happy to help point you in a direction more specific to your specific user case.
Best,

So I'm running through the tutorial for AngularJS:
I have an array defined in the controller and i'm returning different points in the array by calling when i'm looping through ng-repeat {{feature.name}} {{feature.description}}
What i don't understand is lets say i have a third point in the array called "importance" and it's a number from 1 to 10. I don't want to display that number in the html but what i do want to do is apply a different color to the feature if that "importance" number in the array is 10 vs 1
so how do i write an if statement to do this:
i.e.
<p style="**insert if statement: {{if feature.importance == 10}} color:red; {{/if}} **">{{feature.description}}</p>
no idea if that's right but that's what i want to do
I do not think there is if statement available.
For your styling purpose, ng-class can be used.
<p ng-class="{important: feature.importance == 10 }">
ng-switch is also convenient.
-- update --
take a look at:
https://stackoverflow.com/a/18021855/1238847
angular1.2.0RC seems to have ng-if support.
Actually there is a ternary operator in Angular 1.2.0.
<p style="{{feature.importance == 10 ? 'color:red' : ''}}">{{feature.description}}</p>
I think the answer needs an update.
Previously you could use ngIf directive from AngularUI project (code here if you still want to download it), bad news is that it's not maintained any more.
The good news is that it has been added to the official AngularJS repo (unstable branch) and soon will be available in the stable one.
<div ng-if="something"> Foo bar </div>
Will not just hide the DIV element, but remove it from DOM as well (when something is falsy).
ng-class is probably the best answer to your issue, but AngularUI has an "if" directive:
http://angular-ui.github.com/
search for:
Remove elements from the DOM completely instead of just hiding it.
I used "ui-if" to decide if I should render a data value as a label or an input, relative to the current month:
<tbody id="allocationTableBody">
<tr ng-repeat="a in data.allocations">
<td>{{a.monthAbrv}}</td>
<td ui-if="$index < currentMonth">{{a.amounts[0]}}</td>
</tr>
</tbody>
In the case where your priority would be a label, you could create a switch filter to use inside of ng-class as shown in a previous SO answer : https://stackoverflow.com/a/8309832/1036025 (for the switch filter code)
<p ng-class="feature.importance|switch:{'Urgent':'red', 'Warning': 'orange', 'Normal': 'green'}">...</p>
You can also try this line of code below
<div class="{{is_foo && foo.bar}}">
which shows foo.bar if is_foo is true.
This first one is a directive that evaluates whether something should be in the DOM only once and adds no watch listeners to the page:
angular.module('setIf',[]).directive('setIf',function () {
return {
transclude: 'element',
priority: 1000,
terminal: true,
restrict: 'A',
compile: function (element, attr, linker) {
return function (scope, iterStartElement, attr) {
if(attr.waitFor) {
var wait = scope.$watch(attr.waitFor,function(nv,ov){
if(nv) {
build();
wait();
}
});
} else {
build();
}
function build() {
iterStartElement[0].doNotMove = true;
var expression = attr.setIf;
var value = scope.$eval(expression);
if (value) {
linker(scope, function (clone) {
iterStartElement.after(clone);
clone.removeAttr('set-if');
clone.removeAttr('wait-for');
});
}
}
};
}
};
});
This second one is a directive that conditionally applies attributes to elements only once without watch listeners:
i.e.
<div set-attr="{ data-id : post.id, data-name : { value : post.name, condition : post.name != 'FOO' } }"></div>
angular.module('setAttr',[]).directive('setAttr', function() {
return {
restrict: 'A',
priority: 100,
link: function(scope,elem,attrs) {
if(attrs.setAttr.indexOf('{') != -1 && attrs.setAttr.indexOf('}') != -1) {
//you could just angular.isObject(scope.$eval(attrs.setAttr)) for the above but I needed it this way
var data = scope.$eval(attrs.setAttr);
angular.forEach(data, function(v,k){
if(angular.isObject(v)) {
if(v.value && v.condition) {
elem.attr(k,v.value);
elem.removeAttr('set-attr');
}
} else {
elem.attr(k,v);
elem.removeAttr('set-attr');
}
});
}
}
}
});
Of course your can use dynamic versions built into angular:
<div ng-class="{ 'myclass' : item.iscool }"></div>
You can also use the new ng-if added by angularjs which basically replaces ui-if created by the angularui team these will conditionally add and remove things from the DOM and add watch listeners to keep evaluating:
<div ng-if="item.iscool"></div>
What also works is:
<span>{{ varWithValue || 'If empty use this string' }}</span>
I am using tinymce editor for inserting contents to mysql.
I have changed wordpress gallery editor plugin according to my system.
If there is gallery code in content. I convert this code to a symbolic photo, so that user understand there is a gallery , in stead of seeing a code. Like wordpress does.
If there is only 1 gallery in content, i convert this code to image successfully, but if there is more than 1 gallery it fails.
How can i convert all {gallery} code into a symbolic image before saving to db and convert these photos back to {gallery} code again while inserting or updating into mysql.
I am so bad on regular expression.
I think do_gallery RegExp has mistake. How should i change this.
initalising editor like:
ed.onBeforeSetContent.add(function(ed, o) {
ed.dom.loadCSS(url + "/css/gallery.css");
o.content = t._do_gallery(o.content);
});
ed.onPostProcess.add(function(ed, o) {
if (o.get)
o.content = t._get_gallery(o.content);
});
My "do and get gallery" codes like that:
_do_gallery : function(co) {
return co.replace(/\{gallery([^\]]*)\}/g, function(a,b){
var image = '<img src="gallery.gif" class="wpGallery mceItem" title="gallery'+tinymce.DOM.encode(b)+'" />';
console.log(image);
return image;
});
},
_get_gallery : function(co) {
function getAttr(s, n) {
n = new RegExp(n + '="([^"]+)"', 'g').exec(s);
return n ? tinymce.DOM.decode(n[1]) : '';
};
return co.replace(/(?:<p{^>}*>)*(<img[^>]+>)(?:<\/p>)*/g, function(a,im) {
var cls = getAttr(im, 'class');
if ( cls.indexOf('wpGallery') != -1 )
return '<p>{'+tinymce.trim(getAttr(im, 'title'))+'}</p>';
return a;
});
}
If Content is:
<p>Blah</p>
<p>{gallery Name="gallery1" id="82" galeryID="15" sizeId="6" galery_type="list"}</p>
<p>test</p>
this is ok
<img src="gallery.gif" class="wpGallery mceItem" title="gallery Name="tekne1" id="82" galeryID="15" sizeId="6" galery_type="liste"" />
But, if content is:
<p>Blah</p>
<p>{gallery Name="gallery1" id="82" galeryID="15" sizeId="6" galery_type="list"}</p>
<p>test</p>
<p>{gallery Name="gallery2" id="88" galeryID="11" sizeId="1" galery_type="slide"}</p>
<p>test2</p>
it logs
<img src="gallery.gif" class="wpGallery mceItem" title="gallery Name="gallery1" id="82" galeryID="15" sizeId="6" galery_type="list"}</p> <p>test</p> <p>{gallery Name="gallery2" id="88" galeryID="11" sizeId="1" galery_type="slide"" />
I hope i could explain my problem
Thank you.
I suspect that your original regex is a typo, looks like a missing Shift when you hit the ]. Try this:
/\{gallery([^\}]*)\}/g
Then the ([^\}]*) part will (greedily) eat up any sequence of characters that aren't }; your original one would consume any sequence of character that didn't include a ] and the result is that you'd grab everything between the first { and the last } rather than just grabbing the text between pairs of braces.
