如何使 AngularJS 指令停止传播? [英] How can I make an AngularJS directive to stopPropagation?

问题描述

我正在尝试停止传播"以防止在单击 li 中的元素(链接)时关闭 Twitter Bootstrap 导航栏下拉列表.使用这种方法似乎是常见的解决方案.

在 Angular 中，似乎指令是执行此操作的地方?所以我有:

//点击时不关闭下拉菜单directives.directive('stopPropagation', function () {返回 {链接:功能(榆树){$(elm).click(函数(事件){event.stopPropagation();});}};});

...但该方法不属于元素:

TypeError: Object [object Object] 没有方法 'stopPropagation'

我将指令与

联系起来

<div>{{foo.text}}<a stop-propagation ng-click="doThing($index)">clickme</a>

有什么建议吗?

解决方案

目前，一些指令(即 ng:click)会停止事件传播.这阻止了与依赖于捕获此类事件的其他框架的互操作性."

...并且能够在没有指令的情况下进行修复，只需执行:

<a ng-click="doThing($index); $event.stopPropagation();">x</a>

I am trying to "stopPropagation" to prevent a Twitter Bootstrap navbar dropdown from closing when an element (link) inside an li is clicked. Using this method seems to be the common solution.

In Angular, seems like a directive is the place to do this? So I have:

// do not close dropdown on click
directives.directive('stopPropagation', function () {
    return {
        link:function (elm) {            
            $(elm).click(function (event) {                
                event.stopPropagation();
            });
        }
    };
});

... but the method does not belong to element:

TypeError: Object [object Object] has no method 'stopPropagation'

I tie in the directive with

<li ng-repeat="foo in bar">
  <div>
    {{foo.text}}<a stop-propagation ng-click="doThing($index)">clickme</a>
  </div>
</li>

Any suggestions?

解决方案

"Currently some directives (i.e. ng:click) stops event propagation. This prevents interoperability with other frameworks that rely on capturing such events." - link

... and was able to fix without a directive, and simply doing:

<a ng-click="doThing($index); $event.stopPropagation();">x</a>
