我有<div> ng-click,但此<div>子元素,还有ng-click指令。 问题是,子元素上的点击事件会触发 点击事件。< / p>

当我点击他的孩子时,如何阻止父点击事件?

Here is a jsfiddle来说明我的情况。

提前感谢您的帮助。

修改

这是我的代码:

<body ng-app ng-controller="TestController">
<div id="parent" ng-click="parentClick()">
    <div id="child" ng-click="childClick()"></div>

    <p ng-bind="elem"></p>
</div>

<div><p style="text-align:center" ng-bind="childElem"></p></div>
</body>

<script>
function TestController($scope) {
    $scope.parentClick = function() {
        $scope.elem = 'Parent';
    }

    var i = 1;
    $scope.childClick = function() {
        $scope.elem = 'Child';
        $scope.childElem = 'Child event triggered x' + i;
        i++;
    }
}
</script>

您应该使用event.stopPropagation()方法。 见:http://jsfiddle.net/qu86oxzc/3/

<div id="child" ng-click="childClick($event)"></div>

$scope.childClick = function($event) {
    $event.stopPropagation();
    ...
}

使用event.stopPropagation阻止event从子事件处理程序中冒出DOM树。

Updated Demo

&#13;
function TestController($scope) {
  $scope.parentClick = function() {

    $scope.elem = 'Parent';
  }

  var i = 1;
  $scope.childClick = function(e) {
    $scope.elem = 'Child';
    $scope.childElem = 'Child event triggered x' + i;
    i++;

    e.stopPropagation(); // Stop event from bubbling up
  }
}
&#13;
body {
  width: 100%;
  height: 100%;
  overflow: hidden;
}
#parent {
  width: 100px;
  height: 100px;
  position: relative;
  z-index: 1;
  margin: 10px auto 0 auto;
  background-color: #00acee;
  border-radius: 2px;
  cursor: pointer;
}
#parent:hover {
  opacity: 0.5;
}
#child {
  width: 20px;
  height: 20px;
  position: absolute;
  top: 10px;
  right: 10px;
  z-index: 2;
  background-color: #FFF;
  border-radius: 2px;
  cursor: pointer;
}
#child:hover {
  opacity: 0.5;
}
#parent p {
  width: 100%;
  position: absolute;
  bottom: 0px;
  text-align: center;
  color: #FFF;
}

你也可以使用它,因为它使用同样的方法。

<div id="child" ng-click="childClick();$event.stopPropagation();"></div>

即使Pieter Willaert的答案更加美丽,我还是通过一个简单的布尔检查来更新你的小提琴:

http://jsfiddle.net/qu86oxzc/6/

function TestController($scope) {
    $scope.boolean = false;
    $scope.parentClick = function () {
        if (!$scope.boolean) $scope.elem = 'Parent';
        $scope.toggleBoolean();
    }

    var i = 1;
    $scope.childClick = function () {
        $scope.boolean = true;
        $scope.elem = 'Child';
        $scope.childElem = 'Child event triggered x' + i;
        i++;
    }

    $scope.toggleBoolean = function () {
        $scope.boolean = !$scope.boolean;
    }
}

您也可以尝试$event.stopPropagation();。在子函数之后写它。它的工作方式类似于 preventdefault

<body ng-app ng-controller="TestController">
<div id="parent" ng-click="parentClick()">
    <div id="child" ng-click="childClick();$event.stopPropagation();"></div>

    <p ng-bind="elem"></p>
</div>

<div><p style="text-align:center" ng-bind="childElem"></p></div>
</body>
