为什么要要$sce？因为AngularJS里好些地方，比如路径默认是个字符串，不会认为是路径，从而访问不到我们需要的东西，那么我们就可以通过$sce告诉angualrJS这个路径，这样是很安全滴。它有以下几种：
$sce.trustAs(type,name); $sce.trustAsUrl(value); $sce.trustAsHtml(value); $sce.trustAsResourceUrl(value); $sce.trustAsJs(value);
1.trustAsResourceUrl
<html> <head> <meta charset="utf-8"> <script src="https://apps.bdimg.com/libs/angular.js/1.4.6/angular.min.js"></script> </head> <body> <div ng-app="myApp" ng-controller="myCtrl"> 第一种方式：<br/> 有$sce处理：<audio ng-src="{{sceControl(formData.mediaUrl)}}" controls="controls">您的浏览器不支持html5</audio><br/> 无$sce处理：<audio ng-src="{{formData.mediaUrl}}" controls="controls">您的浏览器不支持html5</audio><br/><br/> 第二种方式：<br/> <audio ng-src="{{data.url}}" controls="controls">您的浏览器不支持html5</audio> </div> <script> var app = angular.module('myApp', []); app.controller('myCtrl', function($scope,$sce){ //第一种方式数据源 $scope.formData={ "name":"视频", "mediaUrl":"http://res.audiogroup.cn/res/upload/agx_ims_creative/audio/20160307/bpryk96.mp3"//视频路径 }; $scope.sceControl = $sce.trustAsResourceUrl;//第一种处理方式 //第二种方式数据源 $scope.data={ "name":"视频", "url":"http://res.audiogroup.cn/res/upload/agx_ims_creative/audio/20160307/bpryk96.mp3"//视频路径 }; $scope.data.url = $sce.trustAsResourceUrl($scope.data.url);//第二种处理方式 }); </script> </body> </html>
2.trustAsHtml
<body> <div ng-app="myApp" ng-controller="myCtrl"> 未处理的： <div ng-repeat="item in formData"> {{item.name}} :{{item.htmlVal}} </div> <br/>处理过的：<button ng-click="look()">查看处理结果</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){ //未处理数据源 $scope.formData=[ {"name":"张春玲","htmlVal":"我是<span>张春玲<span>"}, {"name":"sb","htmlVal":"我是<span>sb<span>"} ]; //处理结果 $scope.look = function(){alert $scope.data=[ {"name":"张春玲","htmlVal":"我是<span>张春玲<span>"}, {"name":"sb","htmlVal":"我是<span>sb<span>"} ]; for(var i=0;i<$scope.data.length;i++){ $scope.data[i].htmlVal = $sce.trustAsHtml($scope.data[i].htmlVal); } }; }); </script> </body>
