我只是学习Angularjs,以及如何使用templateUrl加载模板。
我有一个简单的指令:
var mainApp = angular.module("mainApp",[]); mainApp.directive("request",function() { return { restrict: "E",scope: { data: "@" },templateUrl: "te.html" } })
我尝试使用这样的指令:
<!DOCTYPE html> <html> <head> <script src="js/jquery-2.0.0.js"></script> <script src="js/angular.js"></script> <link href="css/bootstrap.css" rel="stylesheet" /> <script src="js/bootstrap.js"></script> <script src="js/main.js"></script> <style type="text/css"> div { background-color: cornflowerblue; } #appPanel { width: 900px; height: 1000px; } </style> </head> <body> <div id="appPanel" ng-app="mainApp" class="container"> <div class="row-fluid" style="height: 15%"> <div class="span12"> title </div> </div> <div class="row-fluid" style="height: 85%"> <div class="span3" style="height: 100%"> actions </div> <div class="span9" style="height: 100%" ng-controller="AppCtrl"> <div ng-repeat="request in data.requests"> <request data="request"></request> </div> </div> </div> </div> </body> </html>
一旦我打开我的页面,我有这个例外:
XMLHttpRequest cannot load file:///Users/chenguangli/Documents/workspace-web/ournotes/te.html. Origin null is not allowed by Access-Control-Allow-Origin. default.html:0 Error: Failed to load template: te.html at Error (<anonymous>) at file:///Users/chenguangli/Documents/workspace-web/ournotes/js/angular.js:4503:17 at file:///Users/chenguangli/Documents/workspace-web/ournotes/js/angular.js:8898:11 at wrappedErrback (file:///Users/chenguangli/Documents/workspace-web/ournotes/js/angular.js:6806:57) at file:///Users/chenguangli/Documents/workspace-web/ournotes/js/angular.js:6882:53 at Object.Scope.$eval (file:///Users/chenguangli/Documents/workspace-web/ournotes/js/angular.js:8011:28) at Object.Scope.$digest (file:///Users/chenguangli/Documents/workspace-web/ournotes/js/angular.js:7876:25) at Object.Scope.$apply (file:///Users/chenguangli/Documents/workspace-web/ournotes/js/angular.js:8097:24) at done (file:///Users/chenguangli/Documents/workspace-web/ournotes/js/angular.js:9111:20) at completeRequest (file:///Users/chenguangli/Documents/workspace-web/ournotes/js/angular.js:9274:7) js/angular.js:5704 js/angular.js:5704 js/angular.js:4800 wrappedErrback js/angular.js:6808 js/angular.js:6882 Scope.$eval js/angular.js:8011 Scope.$digest js/angular.js:7876 Scope.$apply js/angular.js:8097 done js/angular.js:9111 completeRequest js/angular.js:9274 xhr.onreadystatechange js/angular.js:9244
我没有尝试加载模板文件跨域确定(te.html是在同一个fold.html default.html)。
有谁能帮我找出发生了什么吗?
问题是,你正在运行你的例子离开文件系统(使用file://协议)和许多浏览器(Chrome,Opera)限制XHR调用时使用file://协议。 AngularJS模板是通过XHR下载的,这与文件的使用结合://协议导致您得到的错误。
在解决这种情况时,您有几个选择:
>使用Web服务器运行示例(有许多简单的解决方案,如https://code.google.com/p/mongoose/或几行node.js脚本)
>使用< script>将模板嵌入您的index.html文件中指令:http://docs.angularjs.org/api/ng.directive:script,所以您的模板与主HTML文件一起下载,不再需要通过XHR加载它们
>更改浏览器设置以允许通过文件://协议进行XHR调用。例如,这可以在Chrome中完成,如:Allow Google Chrome to use XMLHttpRequest to load a URL from a local file
