jquery - triggering events from nested widgets -

-

i've built simple jquery ui widget creates slider , tries bubble slide event. code below. however, this._trigger undefined in context. how re-trigger event in case?

(function($) {     $.widget("ui.timelineslider", {         options : {         },          _create : function() {             var self = this;             var element = self.element;             var options = self.options;              element.slider({             slide:function (e, ui) {                         this._trigger("slidehappened", null, {date: ui.value});                 }             });         },          destroy : function() {             this.element.next().remove();         },          _setoption : function(option, value) {         }     }); })(jquery);

jquery set invocation context (i.e. this) on events bound through dom node event occurred on. in case div.ui-slider slide occurred on.

to reference widget slide handler reference have saved off slide method can access. luckily have 1 var self = this; in _create.

therefore can replace this self , you're good.
