您好我正在开发angularjs中的Web应用程序。在右上角我有一个下拉框，只有在用户登录后才会激活。我有用户点击下拉菜单的场景，一旦他点击页面上的任何地方我想关闭下拉列表。我很长时间都在努力解决这个问题。我已经创建了plunker，以便了解我正面临的问题。

推荐答案

您可以使用 $ event.stopPropagation 。您可以添加以下代码以使其正常工作

You can use $event.stopPropagation. You can add the following code to make it work

HTML ：

<div class="user" ng-click="OpenDropdown($event)">
   <h1>Dropdown</h1>
   <div class="user-dropdown" ng-show="dp" id="ProfileDropdown"></div>
</div>

JS ：

$scope.OpenDropdown = function(event) {
    if ($scope.dp === false || $scope.dp === undefined) {
        $scope.dp = true;
        event.stopPropagation();
    } else {
        $scope.dp = false;
    }
};
window.onclick = function() {
    if ($scope.dp) {
        $scope.dp = false;
        $scope.$apply();
    }
};
