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);
  }
}
