I have a simple task - retrieve click listener function from DOM element.
I've fased two problems:
addEventListener
function$(element).data('events')
is always emptyTalking about first problem - I think it's not critical as I'm using this function only in one place. But the second problem is a huge pain...
I've tested on pure jQuery environment:
$(element).click(function(){})
$(element).data('events') /*contains events info*/
But with Backbone:
$(element).click(function(){})
$(element).data('events') /*alway empty*/
I'm not a JS guru but it seems like there no bound data at all... Maybe it's just a typical Backbone behaviour, but still - how can I retrieve event handler?
If you are using Backbone.js you should be managing your events inside a Backbone.View object and avoid capturing the event with JQuery directly.
You should try something like this:
var myBody = $( 'body' );
var myDIV = $( '<DIV id="contentDIV"></DIV>' );
myBody.append( myDIV );
var myButton = $( '<button id="aButton">test</button>' );
myDIV.append ( myButton );
var MyView = Backbone.View.extend({
el : myDIV,
events: { 'click button#aButton' : 'doSomething' }, //here you bound the
//event to a function.
initialize: function(){
_.bindAll(this, 'render')
},
render: function(){
myDIV.append('<br>working...');
},
doSomething: function(){
alert( 'doSomething function.. after click event' );
}
});
var myView = new MyView;
myView.render();
