Angular: ng-click and <li> items
提问by serlingpa
I'm using the fabulous UI Bootstrapfor Angular but am having difficulty getting an onclick event raised.
我正在为 Angular使用出色的UI Bootstrap，但是我很难触发 onclick 事件。
Here is the code:
这是代码：
<ul class="dropdown-menu" role="menu">
<li><a><img src='/Content/Images/dept_cargo.png'/> CARGO</a></li>
<li><a><img src='/Content/Images/dept_commercial.png'/> COMMJ</a></li>
<li><a><img src='/Content/Images/dept_executive.png'/> EXECJ</a></li>
<li><a><img src='/Content/Images/dept_travel.png'/> TVL</a></li>
</ul>
{{ currentDepartment }}
I've tried every combination: putting the ng-click="behaviour()" variously inside the li, the a and the img, but nothing seems to work.
我尝试了所有组合：将 ng-click="behaviour()" 以不同的方式放在 li、a 和 img 中，但似乎没有任何效果。
What am I doing wrong?
我究竟做错了什么？
(ideally I'd just like to change the value of a scope variable but I'm thinking calling a behaviour to do the work is better practice)
（理想情况下，我只想更改范围变量的值，但我认为调用行为来完成工作是更好的做法）
This question is not the same as suggested above. The other question is to do with scope, whereas I would be happy just to be able to execute an alert(); from one of my li's.
这个问题与上面建议的不同。另一个问题与范围有关，而我很高兴能够执行 alert(); 来自我的一个 li。

<ul class="dropdown-menu" role="menu">
<li><a ng-click="behaviour()"><img src='/Content/Images/dept_cargo.png'/> CARGO</a></li>
Make sure you have $scope.behaviour = function() {}defined inside of the controller for that code snippet.
确保您已$scope.behaviour = function() {}在控制器内部为该代码片段定义。

You must have an issue in the js code where you set up the controller but if you set it up right, your html should look like this:
您在设置控制器的 js 代码中肯定有问题，但如果设置正确，您的 html 应如下所示：
<ul class="dropdown-menu" role="menu">
<li ng-click="behaviour()"><a><img src='/Content/Images/dept_cargo.png'/> CARGO</a>
</li>
<li ng-click="behaviour()"><a><img src='/Content/Images/dept_commercial.png'/> COMMJ</a>
</li>
<li ng-click="behaviour()"><a><img src='/Content/Images/dept_executive.png'/> EXECJ</a>
</li>
<li ng-click="behaviour()"><a><img src='/Content/Images/dept_travel.png'/> TVL</a>
</li>
</ul>
and in your js:
在你的 js 中：
function myCtrl($scope) {
$scope.behaviour = function () {
alert('asd');
};
}
and here is a working sample: http://jsfiddle.net/97u2jp6d/1/
