backbone.jsHow do I use Backbone.js to find an element in my code?
To find an element in your code using Backbone.js, you can use the $el
property of the Backbone View. $el
is a cached jQuery object that references the DOM element associated with the view.
For example:
var view = Backbone.View.extend({
el: '#my-element'
});
var myView = new view();
console.log(myView.$el);
// Output: [<div id="my-element"></div>]
In the above example, the $el
property is used to cache a jQuery object of the DOM element with the id
of my-element
.
The parts of the code are:
-
var view = Backbone.View.extend({ el: '#my-element' });
- This line creates a Backbone View with an element associated with it. -
var myView = new view();
- This line creates a new instance of the View. -
console.log(myView.$el);
- This line logs the cached jQuery object of the associated element.
