如何从jquery触发ng-change? [英] How to trigger ng-change from jquery?

问题描述

我有一个选择标签，如下所示:

I have a select tag as follows:

<select ng-change="doSomething()" ng-model="myModel"> </select>

，并且我正在使用它的jQueryUI控件(组合框)，从jQuery触发的事件更改"不会触发doSomething().

and I'm using a jQueryUI control for it (combobox), the event "change" triggered from jQuery doesn't trigger doSomething().

您知道如何从外部角度触发ng-change吗?

Do you know how to trigger ng-change from outside angular?

推荐答案

糟糕-这是很糟糕的做法-但是您可以使用angular.element并从位于目标控制器内的元素中获取scope.

Ugh - this is terrible practice - but you can use angular.element and get the scope from an element that resides within the target controller.

示例:

<div ng-controller="myApp">
    <span id="test"></span>
</div>

Javascript:

Javascript:

var scope = angular.element("#test").scope();
scope.doSomething();

您的scope变量现在可以访问在myApp控制器上定义的所有方法.

Your scope variable now has access to all the methods defined on the myApp controller.
