急!我用responseText接收值,在IE中能正常显示,在firefox里却不能显示``` - Web 开发 / Ajax
我用responseText接收值,在IE中能正常显示,在firefox里却不能显示,不知道什么原应,请高手帮忙!
js代码:
function   showpage(url)
{
http_request   =   false;
if(window.XMLHttpRequest)   {
http_request   =   new   XMLHttpRequest();
if   (http_request.overrideMimeType)   {
http_request.overrideMimeType( "text/xml ");
}
}
else   if   (window.ActiveXObject)   {
try   {
http_request   =   new   ActiveXObject( "Msxml2.XMLHTTP ");
}   catch   (e)   {
try   {
http_request   =   new   ActiveXObject( "Microsoft.XMLHTTP ");
}   catch   (e)   {}
}
}
if   (!http_request)   {
window.alert( "no   CreateObject   XMLHttpRequest. ");
return   false;
}
http_request.onreadystatechange=processRequest;
        http_request.open( "POST ",url,true);
http_request.setRequestHeader( "Content-Type ", "application/x-www-form-urlencoded; ");
http_request.send(null);
}


  function   processRequest(){
if(http_request.readystate==4){
if   (http_request.status==200){
document.getElementById( 'content ').innerHTML=http_request.responseText;
}   else   {
                                alert( "ye   mian   yi   chang ");
                }
}
}

传值页面的代码:
<%
response.contenttype= "text/html;charset=iso-8859-1 "
response.write( "1234 ")
%>

支持hejunbin(何俊斌) ，用firebug可以对javascript设断点。一般估计http_request在firefox中的创建过程出错（即你所贴程序的第一个子段｛｝），建议重点跟踪。
