i want to show/hide my raphael svg graph with a button click event
please someone who know how to do this. please help me
i try to do by this way but it's not working.
var p = Raphael(900,70,200,200);
p.circle(20,20,20);
$n("#shide").click(function(){
p.hide();
});
please someone who know how to do this. please help me.
Thanks in advance.
You'd better use the return value of drawing functions.
var element1 = p.circle(20,20,20);
var element2 = p.circle(99,99,20);
$n("#shide").click(function(){
element1.hide();
// element2.hide();
});
Also I have some advanced skills about this kind of problem. These skills will be very usefull when you draw your circles or other things with the ajax response data.
function drawCircle() {
var elementObj = {};
$.ajax({url: '', dataType: 'json', method: 'post', data: yourData, success: function (data) {
elementObj['circle1'] = p.circle(20,20,20);
elementObj['circle2'] = p.circle(99,99,20);
});
return elementObj;
}
Then you call this function like this:
var ele = drawCircle();
var hoverInCb = function () {
ele['circle1'] && ele['circle1'].show();
ele['circle2'] && ele['circle2'].show();
};
var hoverOutCb = function () {
ele['circle1'] && ele['circle1'].hide();
ele['circle2'] && ele['circle2'].hide();
};
These code will work because that the returned elementObj is a 'link' of the object. After the data fetched by ajax request, the elementObj will be filled with data, and the ele variable outside there will also get the new data.
Like this:
var paper = Raphael(10, 50, 320, 200);
paper.circle(10, 10, 10, 10)
.attr({fill: "#000"})
.click(function () {
this.hide();
});

I'm trying to put a Control into an existing div but I don't really know where or how I can force the map.addControl method to show the control (it is a draw control by the way) within an already existing div on the map. I'm using the leaflet draw plugin by the way.
My html looks something like this:
<div class="tooldiv" ng-controller="ClientState">
...
</div>
tooldiv is where the control should be placed.
This is my leaflet config:
var drawnItems = new L.FeatureGroup();
map.addLayer(drawnItems);
var drawControl = new L.Control.Draw({
position: 'topleft',
draw: {
polyline: false,
polygon: {
title: 'Draw a sexy polygon!',
allowIntersection: false,
drawError: {
color: '#b00b00',
timeout: 1000
},
shapeOptions: {
color: '#bada55'
},
showArea: true
},
circle: false,
rectangle: false,
marker: false
},
edit: false
});
// Add and remove DrawControl menu when layer is selected/unselected
this.toggle_layer_edit = function(edit_polygon) {
if (edit_polygon === true) {
if (draw_control_check === null) {
draw_control_check = map.addControl(drawControl);
}
} else {
if (draw_control_check !== null) {
map.removeControl(drawControl);
draw_control_check = null;
}
}
}
While searching for an answer I got the idea that it might not even be possible?
I think you should try overwriting the draw control's onAdd method.
Here's some untested pseudo code (I'm not sure if the assignment & call of the original onAdd method do work like this):
var drawControlOnAdd = drawControl.onAdd;
drawControl.onAdd = function (map) {
var $toolDiv = angular.element('.tooldiv');
var originalDiv = drawControlOnAdd(map);
$toolDiv.html(originalDiv);
return $toolDiv[0];
}

I've just moved to Famo.us and think it has some amazing potential. I am trying to build a new App using Famo.us and will be having 'layered' Views, one of which has a CanvasSurface inside.
My question is about how I would populate the CanvasSurface? I have checked the Docs and while they talk about some of the parameter options they do not tell you how.
I have a View within which I add a Layout and then a Surface to that Layout. Other Views that have ImageSurfaces work fine - but I do not know if I am on the right track with CanvasSurface.
So far I have: (part of inside a BackgroundView.js file)
function BackgroundView() {
View.apply(this, arguments);
_createLayout.call(this);
_createBody.call(this);
_setListeners.call(this);
}
function _createBody() {
this.bodySurface = new CanvasSurface({
canvasSize : [undefined, undefined]
});
var bodyContext= this.bodySurface.getContext('2d');
bodyContext.fillText("Text on Canvas", 100, 100);
this.layout.content.add(this.bodySurface);
}
It runs with no errors, but shows nothing. The CanvasSurface is rendered...
Are there any examples using CanvasSurface or does anyone have any thoughts?
Thanks again for your help in advance.
:)
There are a couple of things I added to your code.. Defining the prototype and prototype.constructor, as well as adding the CanvasSurface to the BackgroundView. I found that canvasSize does not currently support the undefined size attribute like Surface does. You need to be explicit and use pixel size.
Check out what I did to your code.. Hope this helps..
var Engine = require('famous/core/Engine');
var Surface = require('famous/core/Surface');
var View = require('famous/core/View');
var CanvasSurface = require('famous/surfaces/CanvasSurface');
var context = Engine.createContext();
function BackgroundView() {
View.apply(this, arguments);
// _createLayout.call(this);
_createBody.call(this);
// _setListeners.call(this);
}
BackgroundView.prototype = Object.create(View.prototype);
BackgroundView.prototype.constructor = BackgroundView;
function _createBody() {
this.bodySurface = new CanvasSurface({
size:[400,200]
});
var bodyContext= this.bodySurface.getContext('2d');
bodyContext.font="20px Georgia";
bodyContext.fillText("Hello World!",50,50);
this.add(this.bodySurface);
}
var bg = new BackgroundView();
context.add(bg);
Is there a way to get the paper for an element by referencing the element?
I'm creating elements in a loop and with each element i'm creating a new Raphael(...). See sample below.
Basically I want to stop the animation on click, but paper is undefined and calling stop() on the element itself doesn't work either.
$.each(el,function(key,value)
{
var li = $("<li>",{id:"item"+key).appendTo("#myUl");
var ppr = new Raphael($("item"+key),get(0),48,48);
//... do stuff like animate ...
li.click(function()
{
console.log($(this).paper); //undefined
})
})
I was wondering about a closure like below to capture the paper, so when the anonymous func runs, it has the variable captured.
Note, I'm not sure this is the best method overall, something feels a bit clunky about creating a new paper each time, but just trying to address the specific issue.
Untested code, but if you can get it on a fiddle, I think it should be possible to sort.
$.each(el,function(key,value)
{
var li = $("<li>",{id:"item"+key).appendTo("#myUl");
var ppr = new Raphael($("item"+key),get(0),48,48);
(function() {
var myPaper = ppr;
li.click(function()
{
console.log(myPaper);
})
})();
})
You can also attach the paper to the element's "data" using https://api.jquery.com/data/
$.each(el,function(key,value)
{
var li = $("<li>",{id:"item"+key).appendTo("#myUl");
var ppr = new Raphael($("item"+key),get(0),48,48);
li.data("paper", ppr ); // SAVE
li.click(function()
{
console.log($(this).data("paper")); // LOAD
})
})
in order to get familiar with dojo I'm working on a test project which consists of the following components:
data grid (created declaratively), filled with JSON data; clicking on a line will open a dialog containing a form (works)
form (created from template), with several input fields, filled with data from the grid store (works)
FilteringSelect (part of form) (doesn't work, no content)
The FilteringSelect contains dynamic data. In order to keep data traffic low, I thought it wise to get this data when the whole page is loaded and to pass it into the template initialization function.
In fact, I don't really know how to assign the store to the FilteringSelect.
Any help would be greatly appreciated.
Here's my code. I shorten it to the what I consider relevant parts so that it's easier to understand.
Grid Part:
var data_list = fetchPaymentProposalList.fetch();
/*create a new grid*/
var grid = new DataGrid({
id: 'grid',
store: store,
structure: layout
});
// store for FilteringSelect
var beneficiaryList = FetchBeneficiaryList.fetch();
var beneficiaryListStore = new Memory({
identifier : "id",
data : beneficiaryList
});
return {
// function to create dialog with form
instantiate:
function(idAppendTo) {
/*append the new grid to the div*/
grid.placeAt(idAppendTo);
/*Call startup() to render the grid*/
grid.startup();
grid.resize();
dojo.connect(grid, "onRowClick", grid, function(evt) {
var rowItem = this.getItem(evt.rowIndex);
var itemID = rowItem.id[0];
var store = this.store;
var paymentProposalForm = new TmpPaymentProposalForm();
paymentProposalForm._init(store.getValue(rowItem, "..."), ..., beneficiaryListStore);
});
}
};
The beneficiarylist comes as something like this:
return { 12: { id : 1, name : "ABC" }};
The FilteringSelect in the template looks like this:
<input data-dojo-type="dijit/form/FilteringSelect" name="recipient" id="recipient" value="" data-dojo-props="" data-dojo-attach-point="recipientNode" />
Template Init Code looks like this:
_init: function(..., beneficiaryListStore) {
this.recipientNode.set("labelAttr", "name");
this.recipientNode.set("searchAttr", "name");
// here should come the store assignment, I guess???
var dia = new Dialog({
content: this,
title: "ER" + incoming_invoice,
style: "width: 600px; height: 400px;"
});
dia.connect(dia, "hide", function(e){
dijit.byId(dia.attr("id")).destroyRecursive();
});
dia.show();
}
For anyone who's interested, here's my solution:
var beneficiaryList = FetchBeneficiaryList.fetch();
var beneficiaryData = {
identifier : "id",
items : []
};
for(var key in beneficiaryList)
{
if(beneficiaryList.hasOwnProperty(key))
{
beneficiaryData.items.push(lang.mixin({ id: key }, beneficiaryList[key]));
}
}
var beneficiaryListStore = new Memory({
identifier : "id",
data : beneficiaryData
});
That did the trick
I want to refresh a dojo grid in my web page. I tried .refresh which is given in dojotoolkit.org without success. is there any other convenient way to do refreshing? Thanks in advance.
Maybe this helps. This is the way i refresh my Grid:
if(!registry.byId("GraphGrid")){
var grid = new EnhancedGrid({
id: 'GraphGrid',
store: GraphicStore,
query: { ident: "*" },
structure: layout,
rowSelector: '20px',
plugins: {
indirectSelection: {
headerSelector:true,
width:"40px",
styles:"text-align: center;"
}}
},"GridGraphicInMap");
/*Call startup() to render the grid*/
grid.startup();
dojo.connect(grid, "onRowClick", grid, function(evt){
var idx = evt.rowIndex,
item = this.getItem(idx);
// get a value out of the item
var value = this.store.getValue(item, "geom");
highlightGeometry(value,true);
// do something with the value.
});
}
else {
registry.byId("GraphGrid").setStore(GraphicStore);
}
When i first call my function the grid is generated. Evrytime i call the function later only the store is refreshed.
