使用angular和jquery我实现了slidetoggle函数.为了只将这个函数应用于一个特定的HTML元素,我在ng-click函数中使用了一个参数,我的代码工作正常,但是,我想知道是否存在另一个更好的方法来实现angular中的指令和ng-click函数：
的index.html
<!DOCTYPE html>
<html ng-app="myApp" ng-controller="MainController">
<head>
<title></title>
<link type="text/css" rel="stylesheet" href="css/styles.css"/>
</head>
<body>
<div>
<input type="button" ng-click="toggle('first')" value="Toggle First">
<input type="button" ng-click="toggle('second')" value="Toggle Second">
<input type="button" ng-click="toggle('third')" value="Toggle third">
<div class="div1" section="first" toggle="first" >
<p>This is section #1</p>
</div>
<div class="div1" toggle="second">
<p>This is another section #1</p>
</div>
<div class="div1" toggle="third">
<p>This is 3 section #1</p>
</div>
</div>
</body>
<footer>
<script src="js/jquery.min.js"></script>
<script src="js/angular.js"></script>
<script src="js/directives.js"></script>
</footer>
</html>
styles.css的
.div1 {
background: brown;
width: 200px;
height: 200px;
text-align: center;
}
.div1 p {
position: relative;
top: 50%;
}
directives.js
angular.module("myApp",[]) //
.controller('MainController',function($scope) {
$scope.toggle = function(section) {
console.log('<toggle function> section :' + section);
$scope.section = section;
$scope.$broadcast('event:toggle');
}
}) //
.directive('toggle',function() {
return function(scope,elem,attrs) {
scope.$on('event:toggle',function() {
if(attrs.toggle == scope.section){
elem.slidetoggle('fast');
}
});
};
});
我自己的一个问题是我在指令和范围之间进行沟通的方式：
$scope.section = section;
和
if(attrs.toggle == scope.section){
我将不胜感激任何更好的Angular实现的建议.
谢谢

仅供参考,在撰写本文时,AngularJS团队正在添加一个ngAnimate指令,该指令将(希望)提供jQuery目前提供的大部分动画功能,例如：滑动,褪色等,目前IMO严重失踪.
HTML
<div data-ng-controller="MainController">
<input type="button" value="Toggle First" ng-click="Box1=!Box1">
<input type="button" value="Toggle Second" ng-click="Box2=!Box2">
<input type="button" value="Toggle third" ng-click="Box3=!Box3">
<div class="div1" data-slide-toggle="Box1" data-slide-toggle-duration="100" >
<p>This is section #1</p>
</div>
<div class="div2" data-slide-toggle="Box2" data-slide-toggle-duration="2000">
<p>This is another section #1</p>
</div>
<div class="div3" data-slide-toggle="Box3">
<p>This is 3 section #1</p>
</div>
</div>
JS
var myApp = angular.module("myApp",[]);
myApp.controller('MainController',function($scope) {
$scope.Box1 = $scope.Box2 = $scope.Box3 = true;
});
myApp.directive('slidetoggle',function() {
return {
restrict: 'A',scope:{
isOpen: "=slidetoggle"
},link: function(scope,element,attr) {
var slideDuration = parseInt(attr.slidetoggleDuration,10) || 200;
scope.$watch('isOpen',function(newVal,oldVal){
if(newVal !== oldVal){
element.stop().slidetoggle(slideDuration);
}
});
}
};
});
