本文实例讲述了AngularJS使用拦截器实现的loading功能。分享给大家供大家参考，具体如下：
<!DOCTYPE html>
<html lang="zh-CN" ng-app="myApp">
<head>
<meta charset="utf-8">
<meta http-equiv="X-UA-Compatible" content="IE=edge">
<meta name="viewport" content="width=device-width, initial-scale=1">
<script src="jquery.min.js"></script>
<script src="angular.js"></script>
<link rel="stylesheet" href="bootstrap.min.css" rel="external nofollow" >
<style type="text/css">
.mask-loading .loading-icon {
-webkit-animation: rotate 1s linear infinite;
-o-animation: rotate 1s linear infinite;
animation: rotate 1s linear infinite;
position: absolute;
top: 50%;
left: 50%;
width: 30px;
height: 30px;
margin: -20px 0 0 -20px;
border-width: 5px;
border-style: solid;
border-color: #37c3aa #37c3aa #fff #fff;
opacity: .9;
border-radius: 20px;
}
@-webkit-keyframes rotate{
0% {-webkit-transform:rotate(0)}
100% {-webkit-transform:rotate(360deg)}
}
@keyframes rotate{
0% {transform:rotate(0)}
100% {transform:rotate(360deg)}
}
.mask-loading {
position:fixed;
top:0;
right:0;
bottom:0;
left:0;
background:0 0;
z-index:9999;
}
</style>
<script type="text/javascript" src="angular-ui-router.js"></script>
<script type="text/javascript" src="angular-animate.js"></script>
<script type="text/javascript">
var myApp = angular.module('myApp', ['ui.router', 'ngAnimate']);
myApp.config(["$stateProvider", "$httpProvider", '$urlRouterProvider', function ($stateProvider, $httpProvider, $urlRouterProvider) {

.state('b', {

$urlRouterProvider.otherwise('/');

//loading

myApp.controller('bController', function($scope) {

});
</script>
</head>
<body>
<h1>index</h1>
<div id="mask-loading" class="mask-loading" ng-if="loading" style="background-color: rgba(0, 0, 0, 0.17);">
