从 AngularJS 控制器调用 jQuery 函数 [英] Call jQuery function from AngularJS Controller

问题描述

我有一个下面的按钮，点击时会显示一个类似通知的小弹出窗口

I have a below button when on clicked shows a small popup like notification

<button id="element" type="button" onclick="ShowNotifications()" class="btn btn-default" data-container="body" data-toggle="popover" data-placement="bottom" data-content="Text inside popup">Notifications</button>
<script type="text/javascript">
    function ShowNotifications() {
        $('#element').popover('open');
    }
</script>

我的意图是每隔几秒显示一次这个弹出窗口，而不是点击按钮，而是从 AngularJS 控制器.

My Intention is to Show this popup every few seconds without clicking the button, but from the AngularJS Controller.

 var showPop = function () {
    //how can i call that jQuery function here ??
    $timeout(showPop, 1000);
}
$timeout(showPop, 1000);

<小时>

尝试了以下解决方案

Tried with the below solution

app.directive("showNotifications", ["$interval", function ($interval) {
    return {
        restrict: "A",
        link: function(scope, elem, attrs) {          
            $interval(function () {
                $(elem).popover("open");
                alert('hi');
            }, 1000);
        }
    };
}]);

还包括脚本

<link href="//netdna.bootstrapcdn.com/bootstrap/3.1.1/css/bootstrap.min.css" rel="stylesheet" />
<script src="//netdna.bootstrapcdn.com/bootstrap/3.1.1/js/bootstrap.min.js"></script>

<script src="//ajax.googleapis.com/ajax/libs/jquery/1.8.1/jquery.min.js"></script>

<script src="//ajax.googleapis.com/ajax/libs/angularjs/1.2.15/angular.min.js"></script>


<script src="js/app.js"></script>
<script src="js/postsService.js"></script>   
<script src="js/directive.js"></script>

<script src="js/controllers.js"></script>

使用这样的指令

<button id="element" type="button" class="btn btn-default" data-container="body" data-toggle="popover" data-placement="bottom" data-content="Friend request 1" **show-notifications**>Live Notifications</button>

我看到一个错误对象没有方法 popover"

I see an error "the object has no method popover"

推荐答案

指令用于 DOM 操作:

Directives are used for DOM manipulation:

<button show-notifications>

和指令

.directive("showNotifications", ["$interval", function($interval) {
    return {
        restrict: "A",
        link: function(scope, elem, attrs) {
            //On click
            $(elem).click(function() {
                $(this).popover("open");
            });

            //On interval
            $interval(function() {
                $(elem).popover("open");
            }, 1000);
        }
    }
}]);
