Synchronous Ajax Call in Mozilla.

[dmjpro]

function synchronous_ajax(){
    var ajax = null;
    if(typeof ActiveXObject!='undefined') ajax = new ActiveXObject("Microsoft.XMLHTTP");
    else if(typeof XMLHttpRequest!='undefined') ajax = new XMLHttpRequest();
    else{alert('Ajax is not support!!!!!');return;}
 
    alert('Yahoo: ' + ajax);
    ajax.open("GET","http://www.google.co.in/",false);
    ajax.send(null);
    alert(ajax.status);
}

It's working fine in IE 6 but whenever i am trying to run it in Mozilla then it shows me that ajax.open permission denied.
Could you please help me to figure out why it's happening?

Permission is denied because it's from a different domain.

Permission is denied because it's from a different domain.

Then how it's is possible with IE.
I think IE does not check this.

Perhaps you're testing locally in IE?

Locally Test means?

I am simply wrote a HTML file having script and that Ajax call is being called on an event. I am not getting you how you meant Locally Test? :-)

[rnd me]

local = running from eg; c:\docs\mypage. htm in IE6.


its a fluke that it works. micro$oft has changed thier minds (to agree with everyone else that this is bad), and done everything they can to make sure it doesn't happen anymore.

something like a service pack can/will/should kill it at anytime.

enjoy it while it lasts, it wont happen again.

So Ajax call can't be done to different Domain.

Well, you can make a cross-domain request, but either you need to use a web proxy, or you use JSON, or dynamic script tags. There are other ways too. Firefox allows cross-domain requests with privileges.

How to use proxy in Code?
Or should i be using it somewhere else?
One more thing Acoder, what is JSON?

This link should help. Basically, you have a proxy on your web server which passes the request and receives the response from the other server and passes it back to your script. As for JSON, search for it. It's an alternative to XML.
