This is my code:
这是我的代码：

The solution is setting the asyncparameter to true:
解决方案是将async参数设置为true：
xmlhttp.open("GET", filename+"?random="+Math.floor(Math.random()*100000001), true);

In addition to happening when fetching a cross-site URL without proper headers, this error occurs when fetching a local file via XHR (AJAX). Apparently Chrome is being overzealous with its cross-site security measures, not realizing that one file: URL should be considered the same site as another file: URL. This is a problem for many homegrown apps, especially Jasmine (a JavaScript testing framework).
除了在没有正确标头的情况下获取跨站点 URL 时发生之外，在通过 XHR (AJAX) 获取本地文件时也会发生此错误。显然，Chrome 对其跨站点安全措施过于热情，没有意识到应该将一个 file: URL 视为与另一个 file: URL 相同的站点。这是许多本土应用的问题，尤其是 Jasmine（一个 JavaScript 测试框架）。
Still happening as of Chrome version 16.0.912.63 .
从 Chrome 版本 16.0.912.63 开始仍在发生。
I don't know any solution. Workaround is to use Firefox, or any other browser, to run apps served off of file: URLs.
我不知道有什么解决办法。解决方法是使用 Firefox 或任何其他浏览器来运行由 file: URL 提供的应用程序。
