為什么要要$sce？因為AngularJS里好些地方，比如路徑默認是個字符串，不會認為是路徑，從而訪問不到我們需要的東西，那么我們就可以通過$sce告訴angualrJS這個路徑，這樣是很安全滴。它有以下幾種：
$sce.trustAs(type,name);$sce.trustAsUrl(value);$sce.trustAsHtml(value);$sce.trustAsResourceUrl(value);$sce.trustAsJs(value);
1.trustAsResourceUrl
<html><head><meta charset="utf-8"><script src="http://apps.bdimg.com/libs/angular.js/1.4.6/angular.min.js"></script> </head><body><div ng-app="myApp" ng-controller="myCtrl"> 第一種方式：<br/> 有$sce處理：<audio ng-src="{{sceControl(formData.mediaUrl)}}" controls="controls">您的瀏覽器不支持html5</audio><br/> 無$sce處理：<audio ng-src="{{formData.mediaUrl}}" controls="controls">您的瀏覽器不支持html5</audio><br/><br/> 第二種方式：<br/> <audio ng-src="{{data.url}}" controls="controls">您的瀏覽器不支持html5</audio></div><script> var app = angular.module('myApp', []); app.controller('myCtrl', function($scope,$sce){ //第一種方式數據源 $scope.formData={ "name":"視頻", "mediaUrl":"http://res.audiogroup.cn/res/upload/agx_ims_creative/audio/20160307/bpryk96.mp3"http://視頻路徑 }; $scope.sceControl = $sce.trustAsResourceUrl;//第一種處理方式 //第二種方式數據源 $scope.data={ "name":"視頻", "url":"http://res.audiogroup.cn/res/upload/agx_ims_creative/audio/20160307/bpryk96.mp3"http://視頻路徑 }; $scope.data.url = $sce.trustAsResourceUrl($scope.data.url);//第二種處理方式 });</script></body></html>2.trustAsHtml
<body><div ng-app="myApp" ng-controller="myCtrl"> 未處理的： <div ng-repeat="item in formData"> {{item.name}} :{{item.htmlVal}} </div> <br/>處理過的：<button ng-click="look()">查看處理結果</button> <div ng-repeat="item in data"> {{item.name}} :<p ng-bind-html = "item.htmlVal"></p> </div></div><script> var app = angular.module('myApp', []); app.controller('myCtrl', function($scope,$sce){ //未處理數據源 $scope.formData=[ {"name":"張春玲","htmlVal":"我是<span style='color:red;'>張春玲<span>"}, {"name":"sb","htmlVal":"我是<span style='color:red;'>sb<span>"} ]; //處理結果 $scope.look = function(){alert $scope.data=[ {"name":"張春玲","htmlVal":"我是<span style='color:red;'>張春玲<span>"}, {"name":"sb","htmlVal":"我是<span style='color:red;'>sb<span>"} ]; for(var i=0;i<$scope.data.length;i++){ $scope.data[i].htmlVal = $sce.trustAsHtml($scope.data[i].htmlVal); } }; });</script></body>
