多可文档管理系统是一个基于B/S结构（Browser/Server，浏览器/服务器模式）的系统，页面中大量使用了局部动态刷新技术。JavaScript函数如下：
function compressResult(url, params)
{
var style = "";
if (params == null || params == "")
style = "GET";
else
style = "POST";
var isIeClient = (erAgent.indexOf("MSIE") >= 0) ? true : false;
if (isIeClient)
{
var len = 0;
if (params != null)
len = params.length;
var result;
var XMLHTTP;
try
{
XMLHTTP = new ActiveXObject("Microsoft.XMLHTTP");
if(!XMLHTTP) XMLHTTP = new ActiveXObject("MSXML2.XMLHTTP");
}
catch(e)
{
return "";
}
XMLHTTP.Open(style, encodeURI(url), false);
XMLHTTP.setRequestHeader("Content-Length", len);
XMLHTTP.setRequestHeader("Content-Type",
"application/x-www-form-urlencoded; charset=utf-8");
XMLHTTP.Send(params);
if(XMLHTTP.readyState==4)
{
if(document.defaultCharset=="utf-8" && erLanguage=="zh-cn")
{
result = unescape(XMLHTTP.responseText);
}
else
{ result = XMLHTTP.responseText;
}
}
else
{
result = "";
}
delete XMLHTTP;
return result;
}
else
{
g_tmp_txt = "";
g_xmlHttp = new XMLHttpRequest();
g_xmlHttp.onreadystatechange = processReqChange;
g_xmlHttp.open(style, url, false);
g_xmlHttp.setRequestHeader("Content-Type",
"application/x-www-form-urlencoded; charset=utf-8");
g_xmlHttp.send(params);
if(g_xmlHttp.readyState == 4)
{
if(g_xmlHttp.status == 200)
{
g_tmp_txt = g_xmlHttp.responseText;
}
}
delete g_xmlHttp;
return g_tmp_txt;
}
}
