Question

当JQuery select被触发时，如何获取基础autocompleteselect元素？我需要该元素来激活它onchange()。底层select元素是ASP.NET DropDown控件。这是代码：

this._on(this.input, {
        autocompleteselect: function (event, ui) {
               var ele = this; //<---not working
               ui.item.option.selected = true;
               this._trigger("select", event, {
               item: ui.item.option
             });
        },

        autocompletechange: "_removeIfInvalid"
        });

最后我明白了：

autocompleteselect: function (event, ui) {

      ui.item.option.selected = true;
      this._trigger("select", event, {
                         item: ui.item.option
                   });

      var underlyingEle = document.getElementById(
      ui.item.option.parentElement.id // <-- fetching the underlying select element
      ); 
      underlyingEle.onchange();
}

希望这有助于将来的某些人。：）
