Backbone.Handle
Put down your jquery selectors and get a handle on your views' DOM elements.
Create reusable handles to represent particular DOM elements in your views.
Example
MyView = Backbone.View.extend( {
ui : {
"inputFld" : "input[type='text']",
"okButton" : "button.ok!" // assert there is exactly one button in this view with class "ok"
},
events : {
"click okButton" : "_okButton_onClick" // you can use handles here to avoid redundant selectors
},
initialize : function() {
Backbone.Handle.add( this ); // dd backbone.handle functionality to this view.
},
render : function() {
this.resolveHandles(); // resolve the selectors in the ui hash to actual jquery objects
},
_okButton_onClick : function() {
console.log( this.ui.inputFld.val() ); // after resolveHandles() is called, elements are available in this.ui
},
...
} );
Notes
Inspired directly by the ui
hash in Derick Baily's Backbone.Marionette. You may use this mixin in conjunction with Backbone.Marionette, and enjoy the extra !
modifier to assert that there is exactly one element.
