AngularJS实战之ngAnimate插件实现轮播
第一步：引入angular-animate.js
第二步：注入ngAnimate
第三步：定义controller，设置好三张轮播图片
第四步：制作动画效果
第六步：手动启动angular
第二步：注入ngAnimate
var lxApp = angular.module("lxApp", [ 'ngAnimate' ]);
第三步：定义controller，设置好三张轮播图片
.z_login_bg1 {
position: absolute;
width: 100%;
height: 100%;
left: 0;
background-size: cover;
background-repeat: no-repeat;
background-position: center;
background-image: url("themes/default/images/bg1.jpg");
}
.z_login_bg2 {
position: absolute;
width: 100%;
height: 100%;
left: 0;
background-size: cover;
background-repeat: no-repeat;
background-position: center;
background-image: url("themes/default/images/bg2.jpg");
}
.z_login_bg3 {
position: absolute;
width: 100%;
height: 100%;
left: 0;
background-size: cover;
background-repeat: no-repeat;
background-position: center;
background-image: url("themes/default/images/bg3.jpg");
}
<body ng-controller="lxCtrl"> <div ng-if="bgindex==0" class="z_login_bg1 bg_exchange"></div> <div ng-if="bgindex==1" class="z_login_bg2 bg_exchange"></div> <div ng-if="bgindex==2" class="z_login_bg3 bg_exchange"></div> </body>
第四步：制作动画效果
lxApp.animation(".bg_exchange", [ "$animateCss", function($animateCss) {
return {
enter : function(element) {
return $animateCss(element, {
from : {
opacity : 0
},
to : {
opacity : 1
},
duration : 0.5
});
},
leave : function(element) {
return $animateCss(element, {
from : {
opacity : 1
},
to : {
opacity : 0
},
duration : 0.5
});
}
};
} ]);
第五步：使用$interval控制图片切换
lxApp.controller("lxCtrl", function($interval,$scope) {
$scope.bgindex = 0;
$interval(function() {
$scope.bgindex++;
if ($scope.bgindex >= 3) {
$scope.bgindex = 0;
}
}, 5500);
});
第六步：手动启动angular
angular.bootstrap(document,['lxApp']);
