您当前的位置: asp.net 中有一段代码：
-----------------
- C# code
Response.ContentEncoding = System.Text.Encoding.UTF8;
string xmls = "<?xml version="1.0" encoding="utf-8" ?>rn";
xmls += "<apps>rn";
xmls += " <app>rn";
xmls += " <zp_id>1</zu_id>rn";
xmls += " </app>rn";
xmls += "</apps>rn";
Response.ContentType = "text/xml";
Response.Charset = "UTF-8";
Response.AddHeader("Content-Disposition", "attachment;filename="apps.xml"");
Response.Write(xmls);
Response.Flush();
Response.End();
然后在js中用代码
- JScript code
var xhr = new XMLHttpRequest();
xhr.open("GET", "apps.aspx", true);
xhr.send(null);
xhr.onreadystatechange = function(){
if(xhr.readyState == 4)
{
xmlDoc_3 = xhr.responseXML.documentElement; //到这里chrome中就会出"Cannot read property 'documentElement' of null的错误"
}
};
请问什么地方做的不正确呢？如果将 apps.aspx 直接用 apps.xml 代替，chrome就不会出错
但在ie6 7 8 和firefox中确没有任何错误
------解决方案--------------------
Response.AddHeader("Content-Disposition", "attachment;filename="apps.xml"");
这行没用
