仅当变量设置为true时才调用函数 [英] Call a function only if a variable is set to true

问题描述

点击一个div时，我正在调用该函数.

I've a div on click of which I'm calling a function.

<div ng-click="myFunc1()">
    <!--some data here...-->
</div>

<button ng-click="stopmyFunc1===true">Cancel</button>

在控制器中:

$scope.myFunc1 = function(){
  if(myStr == 'abc' && stopmyFunc1 === false){
    //some code here...
  }
};

我需要在单击取消"按钮后停止执行我的功能. 但是，当前使用我编写的代码，似乎没有任何效果.

I need to stop executing my function on click of "cancel' button. But, currently with the code I've written, nothing seems to work.

我该如何解决?

推荐答案

您可以像这样直接在点击处理程序中检查停止标记":

You can check the 'stop flag' directly in your click handler like this:

<div ng-click="stopmyFunc1 === undefined && myFunc1()">
    <!--some data here...-->
</div>

<button ng-click="stopmyFunc1 = true">Cancel</button>

因此，您无需在控制器中进行额外检查...

With that you don't need an additional check in your controller...
