Question

I can’t find out how to delay an event handler for a widget.
I bind the event like this:

enable: function () {
    this.options.isEnabled = true;
    this.element.bind("keyup", $.proxy(this, "_populateList"));
},

I want to call “_populateList” with a delay. but my attempts with setTimeout are not working.

The “_populateList”:

_populateList: function (event) {
    var that = this;
    // do my stuffs
}

Thanks

Try this:

enable: function () {
    this.options.isEnabled = true;
    var that = this;
    this.element.bind("keyup", function(event){
       $(this)
          .delay(1000) // delayed time in milliseconds
          .queue(function(next){
             that._populateList(event);
             next();
          });
    });
},
