在angularjs单独切换的div

本文介绍了在angularjs单独切换的div的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

下面是小提琴：

angular.module("myApp", []) //
.controller('MainController', function($scope) {
    $scope.toggle1 = function() {
        $scope.$broadcast('event:toggle');
    }
    $scope.toggle2 = function() {
        $scope.$broadcast('event:toggle');
    }
}) //
.directive('toggle', function() {
    return function(scope, elem, attrs) {
        scope.$on('event:toggle', function() {
            elem.slideToggle();
        });
    };
});

所以点击toggle1或toggle2将在同一时刻打开这两个容器。但是，我想单独切换他们。我怎样才能做到这一点？

So clicking on toggle1 or toggle2 will open both container at the same moment. But I want to toggle them independently. How can I achieve this?

推荐答案

您必须做些什么来分隔的事件。您可以在广播提供一些额外的数据：

You have to do something to separate the events. You can provide some additional data in the broadcast:

angular.module("myApp", []) //
.controller('MainController', function($scope) {
    $scope.toggle1 = function() {
        $scope.$broadcast('event:toggle','1');
    }
    $scope.toggle2 = function() {
        $scope.$broadcast('event:toggle','2');
    }
}) //
.directive('toggle', function() {
    return function(scope, elem, attrs) {
        scope.$on('event:toggle', function(ev,id) {
            if(attrs.toggle === id){ elem.slideToggle(); }
        });
    };
});

<div class="div1" toggle="1">
  <p>This is section #1</p>
</div>
<div class="div2" toggle="2">
  <p>This is section #2</p>
</div>
