Question

这是我的麻省法典。

function sendAjax(send_data,id)
{
    var ajaxobj;

    alert("After this alert problem occurs!");

    if (window.XMLHttpRequest) ajaxobj = new XMLHttpRequest();
    else ajaxobj = new ActiveXObject("Microsoft.XMLHTTP");

    ajaxobj.onreadystatechange=function()
    {
      if(ajaxobj.readyState==4) 
      {
          if(ajaxobj.responseText.match("confirmPage") != null) document.getElementById(id).innerHTML = ajaxobj.responseText;
          else  
          {
            if(id == "FreshContent") 
            document.getElementById(id).innerHTML = "<a id="refreshpage" onClick="siteSelection( select )">Failed.Click here to Reload!</a>";
            else
            document.getElementById(id).innerHTML = "<a id="refreshpage" onClick="sendAjax(0, latest_gossip_marquee );">Failed.Click here to Reload!</a>";
          }

          }
      else document.getElementById(id).innerHTML="Loading...."; 
    }

    if(id == "FreshContent") ajaxobj.open("GET","sitexyz.php?"+send_data,true);
    else ajaxobj.open("GET","html/xyz.html",true); 
    ajaxobj.send();     
}

Here the FreshContent is a div tag id.it works in opera & firefox but it crashes in my IE7. to see if the page returned by the server is valid the code checks if the returned page has confirmPage string in it.

履行这一职能——它拥有一个,比你重新使用。

function getHTTPObject() {
  var xhr = false;
  if (window.XMLHttpRequest) {
    xhr = new XMLHttpRequest();
  } else if (window.ActiveXObject) {
    try {
      xhr = new ActiveXObject("Msxml2.XMLHTTP");
    } catch(e) {
      try {
        xhr = new ActiveXObject("Microsoft.XMLHTTP");
      } catch(e) {
        xhr = false;
      }
    }
  }
  return xhr;
}
