This is my nhaml code
^ var title=""
!!! XML
!!! Strict
%html{xmlns="http://www.w3.org/1999/xhtml"}
%head
%title
Nhaml Master #{title}
_styles
%body
.page
%h1 = "hello world"
_
_scripts
The resulting HTML renders the last tags as such:
</div>
</body>
<script src="http://ajax.microsoft.com/ajax/jquery/jquery-1.3.2.min.js" type="text/javascript">
</script>
</html>
As _scripts is still at the indentation level of %body +1, why does it close body down before rendering _scripts?
Does it work if you move the scripts above the partial? If so, then the partial may be to blame.
%h1 = "hello world"
_scripts

I am trying to introduce Angular in my Django app. I doubt, that my problem is directly correlated with interpolateProvider which is needed because of django templates... but who knows.
I also have a problem with simplified version of that: http://jsfiddle.net/33417xsm/
This is my current version:
<html ng-app="MyApp">
<head>
<script type="text/javascript" src="/static/js/libs/angular/angular.js"></script>
<script type="text/javascript" src="/static/js/app/app.js"></script>
</head>
<body>
<div ng-controller="MyAppController">
[[ 2 + 4 ]]
<p>[[ MyAppController.product.title ]]</p>
</div>
</body>
</html>
file: app.js
(function(){
var app = angular.module('MyApp', []);
app.config(function ($interpolateProvider) {
$interpolateProvider.startSymbol('[[');
$interpolateProvider.endSymbol(']]');
}
);
app.controller('MyAppController', function (){
this.product = gem;
});
var gem = {
'title': 'Inferno'
};
})();
My result:
As you can guess, I want to also display Inferno. What I am doing wrong?
Your app config is ok. But i see, you didn't understand clearly angular concept.
You must use $scope to binding data. Also you never need "myController.product" like this notation.
I updated your code http://jsfiddle.net/33417xsm/4/
<div ng-app="MyApp" ng-controller="MyAppController">
{{ 2 + 4 }}
<p>{{product.title}}</p>
</div>
var app = angular.module('MyApp', []);
app.controller('MyAppController', function ($scope){
$scope.product = {"title":"product title"};
});

I'm doing a 'load more' type of interaction: user gets at bottom of a page, I load more content.
As I'm using a plugin that formats content in a 'pinterest-style' (masonry), I need to take the output of a rest call, formatted using an ember view, and i'm doing something like:
<div id="list">
</div>
<div id="hidden" style="display:none">
{{#each item in App.itemsController}}
test {{item.id}}
<br />
{{/each}}
</div>
What I want to do is, load the content in the hidden div, and then pass its HTML generated content to the plugin to process in my formatted list view.
If I just copy the #hidden content, the Ember scripts get in, and on subsequent 'load more', content is inserted in the #list, in addition of going in the #hidden div.
That's because I copied the entire handlebars.
So I get rid of the container tag, the one I supposed was wrapping the controller content binding, but even when stripping it from the content I pass to #list, the #list still auto-updates when a 'load more' is called.
I know that's a dirty hackish thing, but in order to improve performance in the client I must take a similar route.

//ACTUAL QUESTION ;)
Given this background, the question is, stripping the container metamorph script tags (like the ones here below), and just take the content inside them, shouldn't get rid of the auto-updating content functionality?
<script id="metamorph-X-start" type="text/x-placeholder"></script>
//ALL THE CONTENT
<script id="metamorph-X-end" type="text/x-placeholder"></script>
Inside those, I just have the actual content generated, like:
<script id="metamorph-9-start" type="text/x-placeholder"></script>
test <script id="metamorph-59-start" type="text/x-placeholder"></script>2873<script id="metamorph-59-end" type="text/x-placeholder"></script>
<br>
<script id="metamorph-9-end" type="text/x-placeholder"></script>
<script id="metamorph-10-start" type="text/x-placeholder"></script>
test <script id="metamorph-60-start" type="text/x-placeholder"></script>2872<script id="metamorph-60-end" type="text/x-placeholder"></script>
<br>
<script id="metamorph-10-end" type="text/x-placeholder"></script>
The alternative is programmatically render the template inside a variable and process that, which is surely a better way of doing this, but I just wonder how the #each binding works internally as I thought the metamorph was doing that.
Have you looked into using a CollectionView and calling the plugin through the didInsertElement callback?
e.g.
MyList = Ember.CollectionView.extend({
itemViewClass: 'App.ListItem',
didInsertElement: function(){
view.$().jqueryPlugin({ ... })
}
})
I would like to know how to configure Mathjax in Django in a Q&A system where Questions and Answers will be based on LaTeX format.
I have tried to add:
<script type="text/javascript"
src="http://cdn.mathjax.org/mathjax/latest/MathJax.js?config=TeX-AMS-MML_HTMLorMML"></script>
into the html template where the questions and answers will be displayed to no avail.
Thanks.
If the page's content is dynamically created, you will need to call MathJax after the content has been loaded. See the documentation for details. The main idea is that you have to include
MathJax.Hub.Queue(["Typeset",MathJax.Hub]);
in the javascript that is executed after the content is in place.
fOR Dynamic content here's is the working solution. I used AsciiMath Input as the input format in mathjax that incorporates ASCIIMathML.
In the base.html add the following scripts:
<script>
MathJax = {
loader: {load: ['input/asciimath', 'output/chtml']}
}
</script>
<script src="https://polyfill.io/v3/polyfill.min.js?features=es6"></script>
<script type="text/javascript" id="MathJax-script" async src="https://cdn.jsdelivr.net/npm/mathjax#3/es5/startup.js"></script>
<script type="text/javascript" id="MathJax-script" async src="https://cdn.jsdelivr.net/npm/mathjax#3/es5/tex-chtml.js">
and remember to enclose the dynamic text by back-ticks”, i.e., `...` So in the django-admin you can simply enter sqrt(50) as ` sqrt(50) ` or ` x^2 ` and the dynamic content which is passed from view to the template, in the template you surround {{e1}} by back-ticks
` {{ e1 }} `
instead of
{{ e1 }} where e1 is the dynamic content. So if e1 which was earlier displayed in plain text as 2*sqrt(2) will now be displyed as 2√2.
For more details: http://docs.mathjax.org/en/latest/input/asciimath.html#asciimath-support
see https://docs.mathjax.org/en/latest/web/configuration.html. For the demo indicated here to work you should also add ['\(', '\)'] to inlineMath:
<script>
MathJax = {
tex: {
inlineMath: [['$', '$'], ['\\(', '\\)']]
},
svg: {
fontCache: 'global'
}
};
</script>
<script type="text/javascript" id="MathJax-script" async
src="https://cdn.jsdelivr.net/npm/mathjax#3/es5/tex-svg.js">
</script>
Hello I will start by presenting my code.
#defining("addPostForm"){formId =>
#main("Add a blog post.") {
<h1>Add a blog post</h1>
#errors
#form(routes.Application.addPost, 'id -> "#formId") {
#inputText(name = "content", required = true)
<input type="submit" value="Create">
}
<script type="text/javascript">
$("##formId").validator();
</script>
}
}
Why is it that the #fromId in the #form won't be evaluated by play? This is a snippet of the generated html page.
<form action="/addPost" method="POST" id="#formId">
But later in the page it is working fine as this is generated.
<script type="text/javascript">
$("#addPostForm").validator();
</script>
I think it does not work because you already in a Scala code section, try this :
#form(routes.Application.addPost, 'id -> formId)
The later code is not included in a code section, so it works as expected.
<script type="text/javascript">
document.getElementById("IDOFELEMENT");
</script>
What is the correct way to turn this into a link?
Can I write
<script type="text/javascript">
document.getElementById("IDOFELEMENT").href("http://www.address.com");
</script>
Many thanks.
javascript:
// this changes the href value<br>
document.getElementById("IDOFELEMENT").href = "http://www.address.com";
and the html:
<a href="www.toBeChanged.com" id="IDOFELEMENT">To Website< /a>
You should specify what kind of element is IDOFELEMENT. But you can't convert it to a link by just adding a href attribute, it only works if IDOFELEMENT
is an hyperlink like <a id="IDOFELEMENT">stuff</a>
Simplest way is to add an onclick event to the element that changes the url to desired address:
<script type="text/javascript">
var element = document.getElementById("IDOFELEMENT");
element.setAttribute('onclick', 'window.location.href=\'http://address.com\'');
</script>
Or if you wanna wrap it with a hyperlink:
<script type="text/javascript">
var element = document.getElementById("IDOFELEMENT");
var parent = element.parentNode;
var link = document.createElement('a');
link.href = 'http://www.address.com';
link.appendChild(element.cloneNode(true));
parent.replaceChild(link, element);
</script>
I hope this helps you.
I came accross the issue - Javascript error: Cannot read property 'parentNode' of null.
I discovered this was due to executing this code while the DOM is not ready.
window.onload solved the issue for me.
<script>
window.onload = function() {
var element = document.getElementById("IDOFELEMENT");
var parent = element.parentNode;
var link = document.createElement('a');
link.href = 'http://www.google.com';
link.appendChild(element.cloneNode(true));
parent.replaceChild(link, element);
};
</script>
You just need to wrap your element in an anchor tag as follows...
<a href="http://www.address.com">
<div id="IDOFELEMENT">
... content ...
</div>
</a>
