            <button>X</button>
        </div>
    </div>
  </div>
</html>

js file -

＆＃13;

var myApp = angular.module("myApp", []);

myApp.controller('mainCtrl', function($scope, $rootScope) {
  //$scope.toggleClick = function(){
  //  $rootScope.$broadcast("toogleDiv","");
  //};
});

myApp.directive('toggle', function () {
    return {
        restrict:'C',
        link: function (scope, element, attrs) {
           
            scope.toggleClick = function(){
              alert(element.attr('id'));
              element.slideToggle();
            };
        }                  
    }
});

＆＃13;

无论是哪个段落项目我点击，第三个div只切换。但是，如果您看到toggle指令在所有div上。所以基本上所有div都应该滑动，但只有最后一个才能滑动。

style.css -

＆＃13;

.login-div{
    margin: 50px;
    width: 200px;
    padding:10px;
    background-color: black;
    box-shadow: 0px 0px 15px 1px rgba(50, 50, 50, 1);
    position: relative;
}

.login, .sign-up {
    padding:15px;
    background-color:#EFF7F7;
    border: solid 1px gray;
}

.btn-close {
    margin-top: 10px;
    text-align: right;
}

.btn-login{
    width: 100%;
    margin: 10px 0px;
}

input{
    border: 1px solid #ccc;
    border-radius: 4px;
    padding: 5px 0 5px 5px;
    color: #555;
    width: 162px;
}

a{
    display: inline-block;
    text-decoration: none;
}

link{
    text-align: right;
}



p{
  cursor: pointer;
}

Answer 1

在指令定义中添加scope:{},可以解决您的问题。您的指令需要一个隔离的范围才能重用它。

问题是toggleClick定义被分配给父作用域，基于你的html意味着div3指令的执行被覆盖并且是最后定义的函数。出于兴趣，如果你交换你的div，你可能会注意到最后定义的div总是被点击的。
