Okay, so I've read several other questions regarding Backbone views and events not being fired, however I'm still not getting it sadly. I been messing with Backbone for about a day, so I'm sure I'm missing something basic. Here's a jsfiddle with what I'm working with: http://jsfiddle.net/siyegen/e7sNN/3/
(function($) {
var GridView = Backbone.View.extend({
tagName: 'div',
className: 'grid-view',
initialize: function() {
_.bindAll(this, 'render', 'okay');
},
events: {
'click .grid-view': 'okay'
},
okay: function() {
alert('moo');
},
render: function() {
$(this.el).text('Some Cow');
return this;
}
});
var AppView = Backbone.View.extend({
el: $('body'),
initialize: function() {
_.bindAll(this, 'render', 'buildGrid');
this.render();
},
events: {
'click button#buildGrid': 'buildGrid'
},
render: function() {
$(this.el).append($('<div>').addClass开发者_如何学JAVA('gridApp'));
$(this.el).append('<button id="buildGrid">Build</button>');
},
buildGrid: function() {
var gridView = new GridView();
this.$('.gridApp').html(gridView.render().el);
}
});
var appView = new AppView();
})(jQuery);
The okay
event on the GridView does not fire, I'm assuming because div.grid-view
does not exist when the event is first bound. How should I handle the binding and firing of an event that's built on a view dynamically? (Also, it's a short example, but feel free to yell at me if I'm doing anything else that I shouldn't)
Your problem is that the events on GridView:
events: {
'click .grid-view': 'okay'
}
say:
when you click on a descendent that matches
'.grid-view'
, callokay
The events are bound with this snippet from backbone.js
:
if (selector === '') {
this.$el.on(eventName, method);
} else {
this.$el.on(eventName, selector, method);
}
So the .grid-view
element has to be contained within your GridView's this.el
and your this.el
is <div class="grid-view">
. If you change your events
to this:
events: {
'click': 'okay'
}
you'll hear your cows (or "hear them in your mind" after reading the alert depending on how crazy this problem has made you).
