這段程式碼,我找了很久終於找到了~

轉錄自 ptt WEB_DESIGN

function makeRequest(url) 
{
url += "?n="+Math.random()*100000000;
http_request = false;
if (window.XMLHttpRequest) { // Mozilla, Safari,...
http_request = new XMLHttpRequest();
if (http_request.overrideMimeType)
{
http_request.overrideMimeType('text/xml');
}
}
else if (window.ActiveXObject) { // IE
try {
http_request = new ActiveXObject("Msxml2.XMLHTTP");
}
catch (e)
{
try
{
http_request = new ActiveXObject("Microsoft.XMLHTTP");
}
catch (e) {}
}
}
if (http_request) {
http_request.onreadystatechange = alertContents;
http_request.open('GET', url, true); http_request.send(null);
}
}


function alertContents() { if (http_request.readyState == 4) { alter(http_request.status); } }
