Answer 1

XmlHttpRequest只能用于调用服务页面的域/服务器本地服务。

因此，如果您正在提供以下网页：

http://www.example.com/page1

您不能将XmlHttpRequest设为：

http://www.sample.com/webservice

Answer 2

由于您要设置Content-type，因此您还需要将其设置为使用UTF-8。而且我认为它应该是application/xml（source）。

xmlhttp.setRequestHeader("Content-Type", "application/xml; charset=utf-8");

否则，您是否已验证XML格式正确？尝试将其保存为完整的XML文件，然后在浏览器中打开它。

Answer 3

对于Internet Explorer

适用于Firefox
