這篇文章主要介紹了如何利用CSS3在Angular中實(shí)現(xiàn)動(dòng)畫效果，對(duì)angular動(dòng)畫相關(guān)知識(shí)感興趣的朋友一起學(xué)習(xí)吧

廢話不多說(shuō)了，直接給大家貼實(shí)例代碼。

直接看例子：

<!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;}
/*顯示操作*/
.box.ng-enter{opacity:0;}
.box.ng-enter-active{opacity:1;}
/*隱藏操作*/
.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>

引入angular-animate插件，我們綁定了ng-if指令，在刪除和添加DOM節(jié)點(diǎn)的時(shí)候，angular會(huì)添加指定的class，方便我們完成動(dòng)畫。

.ng-enter
.ng-enter-active
.ng-leave
.ng-leave-active

現(xiàn)在再看看顯示和隱藏。

<!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;}
/*顯示操作*/
.box.ng-hide-remove{opacity:0;}
.box.ng-hide-remove-active{opacity:1;}
/*隱藏操作*/
.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

這個(gè)例子我們使用的是ng-show，屬于顯示和隱藏。上一個(gè)例子是ng-if，屬于添加和刪除。

回顧上一節(jié)我們提到的路由，我們可以結(jié)合起來(lái)操作。

<!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;}
/*顯示操作*/
.box.ng-enter{opacity:0;}
.box.ng-enter-active{opacity:1;}
/*隱藏操作*/
.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="$location.path('aaa')">首頁(yè)</a>
<a href="javascript:void(0);" ng-click="$location.path('bbb')">內(nèi)容</a>
<a href="javascript:void(0);" ng-click="$location.path('ccc')">標(biāo)題</a>
<div class="box" ng-view></div>
</div>
<script type="text/javascript">
var m1 = angular.module('myApp',['ngRoute','ngAnimate']);
m1.config(['$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>

這樣在切換頁(yè)面的時(shí)候就有淡入淡出的效果。

再回顧前面的幾章講的百度搜索：

<!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;}
/*顯示操作*/
.box.ng-enter{opacity:0;}
.box.ng-enter-active{opacity:1;}
/*隱藏操作*/
.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">{wppm3vysvbp}</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>

通過(guò)跨域我們得到百度返回過(guò)來(lái)的數(shù)據(jù)，依次過(guò)渡顯示到頁(yè)面上。

下面來(lái)看JS動(dòng)畫的例子：

<!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（刪除）
leave : function(element,done){
//console.log(element,done); //元素節(jié)點(diǎn)&刪除節(jié)點(diǎn)的回調(diào)函數(shù)
$(element).animate({
width : 0,
height : 0
},1000,done);
},
//show（填充）
enter : function(element,done){
//ng-if會(huì)動(dòng)態(tài)創(chuàng)建元素，元素默認(rèn)就有200的高寬。。。
$(element).css({
width : 0,
height : 0
}).animate({
width : 200,
height : 200
},1000,done);
}
};
});
m1.controller('Aaa',['$scope',function($scope){
$scope.bBtn = true;
}]);
</script>
</body>
</html>

JS動(dòng)畫我們使用JQ的動(dòng)畫庫(kù)來(lái)完成，注意我們?cè)谝晥D上使用的是ng-if，表示添加和刪除DOM節(jié)點(diǎn)，所以我們?cè)诳刂破鱮eturn leave&enter。

JS動(dòng)畫有了ng-if，自然就是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（隱藏）
addClass : function(element,sClass,done){
//console.log(element,sClass,done); //元素節(jié)點(diǎn)&樣式名&刪除節(jié)點(diǎn)的回調(diào)函數(shù)
$(element).animate({
width : 0,
height : 0
},1000,done);
},
//show（顯示）
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>

在控制器return addClass&removeClass，表示隱藏和顯示。
