Ajax is not working in firefox and opera

[benoypaul]

I have the following javascripts which is working in IE, but not working in Firefox and opera.

var xmlhttp=null;
function showCustomer(str)
{
  xmlhttp=getxmlhttp();
 
if (xmlhttp==null)
{
  alert("Your Browser does not support AJAX");
  return;
 }
 
 var url="search.php";
 url=url+"?q="+str;
  url=url+"&sid="+Math.random();
   xmlhttp.onreadyStateChange=statechanged;
   xmlhttp.open('get',url,false);
      xmlhttp.send(null);
 
 
  }  
 
function statechanged()
{
 alert("ok"); 
 if (xmlhttp.readyState==4)
 {
 
         document.getElementById("txt").innerHTML=xmlhttp.responseText;
 
}      
 
 }
 
 function getxmlhttp()
 {
   xmlhttp=null;
   try
  {
  // Firefox, Opera 8.0+, Safari
  xmlHttp=new XMLHttpRequest();
  }
catch (e)
  {
  // Internet Explorer
  try
    {
    xmlHttp=new ActiveXObject("Msxml2.XMLHTTP");
    }
  catch (e)
    {
    xmlHttp=new ActiveXObject("Microsoft.XMLHTTP");
    }
  }
return xmlHttp;
}

How to solve this problem.

Thanks in advance

Welcome to TSDN.

The probable reason why it is not working is that the global variable is "xmlhttp", but when using the XMLHttpRequest object, you have used "xmlHttp" (note the case difference).

Thanks for the response.

I have changed all varables as "xmlhttp". But still above problem exists. ie It is working in IE and not in firefox and opera.

Perhaps onreadyStateChange should be onreadystatechange.

What error do you get? Check the console for errors or Firebug if you have it.

Thanks a lot

My code is working in firefox as well as in opera. I have changed onreadyStateChange to onreadystatechange .Then it is working in Opera, but not in firefox. . After this , I changed xmlhttp.open('GET',url,false) to xmlhttp.open('GET',url,true) .Now it is working IE, Opera and Firefox.

It's good that you got it working, but how did it work in the other browsers with those mistakes. That last argument makes AJAX asynchronous.

xmlhttp.open('get',url,false);

Replace with

xmlhttp.open('get',url,true);

benoypaul managed to solve this, but thanks anyway for pointing out the change required.

...I changed xmlhttp.open('GET',url,false) to xmlhttp.open('GET',url,true) .Now it is working IE, Opera and Firefox.

Thank you for the info! Was having the same issue and this resolved it for me as well.
