Web Front-endHTML Tutorial(10) Reasons and solutions for the failure of the ng-inlude directive to load the page_html/css_WEB-ITnose
The ng-include directive provided in angularjs is very similar to the
The parent page parent.html code is as follows:
<html> <head> <script src="angular-1.2.2/angular.js"></script> <script> function rootController($scope,$rootScope,$injector) { $rootScope.name = "aty"; $rootScope.age = 25; } </script> </head> <body ng-app ng-controller="rootController"> <h1 id="Hello-name">Hello, {{name}}!</h1> <h1 id="Hello-age">Hello, {{age}}!</h1> <div id="included" ng-include="'child.html'"> <input type="button" value="2"/> </div> </body></html> The included child page child.html code is as follows:
<div> <h1 id="included-name">included, {{name}}!</h1> <h1 id="included-age">included, {{age}}!</h1> </div>
I use IE11 and Chrome39 runs parent.html and finds that the child.html page cannot be included in parent.html. The error message reported under IE is as follows:
Error: 拒绝访问。 at Anonymous function (file:///D:/learn/angular-1.2.2/angular.js:7852:7) at sendReq (file:///D:/learn/angular-1.2.2/angular.js:7720:9) at serverRequest (file:///D:/learn/angular-1.2.2/angular.js:7454:9)
The error message reported under chrome is as follows:
XMLHttpRequest cannot load file:///D:/learn/include.html. Cross origin requests are only supported for protocol schemes: http, data, chrome, chrome-extension, https, chrome-extension-resource.Failed to execute 'send' on 'XMLHttpRequest': Failed to load 'file:///D:/learn/include.html'.
The prompt under IE is a bit obscure, but the chrome prompt is obvious: cross-domain access is not allowed . From the above error message, you can see that when using the ng-include directive, AJAX request XMLHttpRequest will be used. However, we opened parent.html directly with the browser and did not access it through the web container, so there was a cross-domain access problem, and loading child.html failed. The solution is simple: deploy the code to a web container such as tomcat and access it through http.
When I usually practice javascript or JS framework, I use relatively lightweight tools. I don’t use IDEs like Eclipse. I usually use Notepad writes js code. Notepad can easily call the browser installed on the machine. Instructions like ng-include must be supported by the web container. You can use the front-end development artifact webstorm. When this tool runs HTML, it will automatically start the built-in web container, so that the ng-include instruction will not report an error.
