No more nonsense, let me just post the example code for you.
Look directly at the example:
<!DOCTYPE HTML>
<html ng-app="myApp">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>ngAnimate插件1</title> <script type="text/javascript" src="https://code.angularjs.org/1.3.8/angular.min.js"></script>
<script type="text/javascript" src="https://code.angularjs.org/1.3.8/angular-animate.min.js"></script> <style type="text/css">
.box{width:200px;height:200px;background-color:red;transition:1s all;}
/*显示操作*/
.box.ng-enter{opacity:0;}
.box.ng-enter-active{opacity:1;}
/*隐藏操作*/
.box.ng-leave{opacity:1;}
.box.ng-leave-active{opacity:0;}
</style>
</head>
<body>
<div ng-controller="Aaa">
<input type="checkbox" ng-model="bBtn">
<div class="box" ng-if="bBtn"></div>
</div>
<script type="text/javascript">
var m1 = angular.module('myApp',['ngAnimate']);
m1.controller('Aaa',['$scope',function($scope){
$scope.bBtn = true;
}]);
</script>
</body>
</html>
Introducing the angular-animate plug-in, we have bound the ng-if instruction. When deleting and adding DOM nodes, angular will add the specified class to facilitate us to complete the animation.
.ng-enter
.ng-enter-active
.ng-leave
.ng-leave-active
Now look at showing and hiding.
<!DOCTYPE HTML>
<html ng-app="myApp">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>ngAnimate插件4</title>
<script type="text/javascript" src="https://code.angularjs.org/1.3.8/angular.min.js"></script>
<script type="text/javascript" src="https://code.angularjs.org/1.3.8/angular-animate.min.js"></script>
<style type="text/css">
.box{width:200px;height:200px;background-color:red;transition:1s all;}
/*显示操作*/
.box.ng-hide-remove{opacity:0;}
.box.ng-hide-remove-active{opacity:1;}
/*隐藏操作*/
.box.ng-hide-add{opacity:1;}
.box.ng-hide-add-active{opacity:0;}
</style>
</head>
<body>
<div ng-controller="Aaa">
<input type="checkbox" ng-model="bBtn">
<div class="box" ng-show="bBtn"></div>
</div>
<script type="text/javascript">
var m1 = angular.module('myApp',['ngAnimate']);
m1.controller('Aaa',['$scope',function($scope){
$scope.bBtn = true;
}]);
</script>
</body>
</html>
.ng-hide-remove
.ng-hide-remove-active
.ng-hide-add
.ng-hide-add-active
In this example we use ng-show, which belongs to display and hide. The previous example is ng-if, which belongs to addition and deletion.
Recalling the routing we mentioned in the previous section, we can combine them.
<!DOCTYPE HTML>
<html ng-app="myApp">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>ngAnimate插件2</title> <script type="text/javascript" src="js/angular.min.js"></script>
<script type="text/javascript" src="http://cdn.bootcss.com/angular.js/1.3.0-beta.13/angular-route.min.js"></script>
<script type="text/javascript" src="http://cdn.bootcss.com/angular.js/1.3.0-beta.13/angular-animate.min.js"></script> <style type="text/css">
.box{transition:1s all;position:absolute;}
/*显示操作*/
.box.ng-enter{opacity:0;}
.box.ng-enter-active{opacity:1;}
/*隐藏操作*/
.box.ng-leave{opacity:1;}
.box.ng-leave-active{opacity:0;}
</style>
</head>
<body>
<div ng-controller="Aaa">
<a href="javascript:void(0);" ng-click="$location.path('aaa')">首页</a>
<a href="javascript:void(0);" ng-click="$location.path('bbb')">内容</a>
<a href="javascript:void(0);" ng-click="$location.path('ccc')">标题</a>
<div class="box" ng-view></div>
</div>
<script type="text/javascript">
var m1 = angular.module('myApp',['ngRoute','ngAnimate']);
m1.config(['$routeProvider',function($routeProvider){
$routeProvider.when('/aaa',{
template : '<h1>AAA</h1>{{name}}',
controller : 'Aaa'
}).when('/bbb',{
template : '<h1>BBB</h1>{{name}}',
controller : 'Bbb'
}).when('/ccc',{
template : '<h1>CCC</h1>{{name}}',
controller : 'Ccc'
}).otherwise({
redirectTo : '/aaa'
});
}]);
m1.controller('Aaa',['$scope','$location','$routeParams',function($scope,$location,$routeParams){
$scope.name = 'xiecg-Aaa';
$scope.$location = $location;
}]);
m1.controller('Bbb',['$scope',function($scope){
$scope.name = 'xiecg-Bbb';
}]);
m1.controller('Ccc',['$scope',function($scope){
$scope.name = 'xiecg-Ccc';
}]);
</script>
</body>
</html>
This will have a fade-in and fade-out effect when switching pages.
Recall the Baidu search mentioned in the previous chapters:
<!DOCTYPE HTML>
<html ng-app="myApp">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>ngAnimate插件3</title> <script type="text/javascript" src="js/jquery-1.11.1.js"></script>
<script type="text/javascript" src="https://code.angularjs.org/1.3.8/angular.min.js"></script>
<script type="text/javascript" src="https://code.angularjs.org/1.3.8/angular-animate.min.js"></script> <style type="text/css">
.box{transition:1s all;}
/*显示操作*/
.box.ng-enter{opacity:0;}
.box.ng-enter-active{opacity:1;}
/*隐藏操作*/
.box.ng-leave{display:none;}
.box.ng-enter-stagger{animation-delay:0.1s;}
</style>
</head>
<body>
<div ng-controller="Aaa">
<input type="text" ng-model="name" ng-keyup="change(name)">
<input type="button" ng-click="change(name)" value="搜索">
<ul>
<li class="box" ng-repeat="d in data">{{d}}</li>
</ul>
</div>
<script type="text/javascript">
var m1 = angular.module('myApp',['ngAnimate']);
m1.controller('Aaa',['$scope','$http','$timeout',function($scope,$http,$timeout){
var timer = null;
$scope.data = [];
$scope.change = function(name){
$timeout.cancel(timer);
timer = $timeout(function(){
$http({
method : 'JSONP',
url : 'https://sp0.baidu.com/5a1Fazu8AA54nxGko9WTAnF6hhy/su?wd='+name+'&cb=JSON_CALLBACK',
}).success(function(data,state,headers,config){
console.log(data);
$scope.data = data.s;
}).error(function(data){
console.log(data);
});
},500);
};
}]);
</script>
</body>
</html>
Through cross-domain we get the data returned by Baidu, and transition it to the page in sequence.
Let’s look at an example of JS animation:
<!DOCTYPE HTML>
<html ng-app="myApp">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>ngAnimate插件5</title>
<script type="text/javascript" src="js/jquery-1.11.1.js"></script>
<script type="text/javascript" src="https://code.angularjs.org/1.3.8/angular.min.js"></script>
<script type="text/javascript" src="https://code.angularjs.org/1.3.8/angular-animate.min.js"></script>
<style type="text/css">
.box{width:200px;height:200px;background-color:red;}
</style>
</head>
<body>
<div ng-controller="Aaa">
<input type="checkbox" ng-model="bBtn">
<div class="box" ng-if="bBtn"></div>
</div>
<script type="text/javascript">
var m1 = angular.module('myApp',['ngAnimate']);
//ng-if
m1.animation('.box',function(){
return {
//hide（删除）
leave : function(element,done){
//console.log(element,done); //元素节点&删除节点的回调函数
$(element).animate({
width : 0,
height : 0
},1000,done);
},
//show（填充）
enter : function(element,done){
//ng-if会动态创建元素，元素默认就有200的高宽。。。
$(element).css({
width : 0,
height : 0
}).animate({
width : 200,
height : 200
},1000,done);
}
};
});
m1.controller('Aaa',['$scope',function($scope){
$scope.bBtn = true;
}]);
</script>
</body>
</html>
We use JQ animation library to complete JS animation. Note that we use ng-if on the view, which means adding and deleting DOM nodes, so we return leave&enter in the controller.
With ng-if, JS animation is naturally ng-show.
<!DOCTYPE HTML>
<html ng-app="myApp">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>ngAnimate插件5</title>
<script type="text/javascript" src="js/jquery-1.11.1.js"></script>
<script type="text/javascript" src="https://code.angularjs.org/1.3.8/angular.min.js"></script>
<script type="text/javascript" src="https://code.angularjs.org/1.3.8/angular-animate.min.js"></script>
<style type="text/css">
.box{width:200px;height:200px;background-color:red;}
</style>
</head>
<body>
<div ng-controller="Aaa">
<input type="checkbox" ng-model="bBtn">
<div class="box" ng-show="bBtn"></div>
</div>
<script type="text/javascript">
var m1 = angular.module('myApp',['ngAnimate']);
//ng-show
m1.animation('.box',function(){
return {
//hide（隐藏）
addClass : function(element,sClass,done){
//console.log(element,sClass,done); //元素节点&样式名&删除节点的回调函数
$(element).animate({
width : 0,
height : 0
},1000,done);
},
//show（显示）
removeClass : function(element,sClass,done){
$(element).animate({
width : 200,
height : 200
},1000,done);
}
};
});
m1.controller('Aaa',['$scope',function($scope){
$scope.bBtn = true;
}]);
</script>
</body>
</html>
Return addClass&removeClass in the controller, indicating hiding and displaying.
