XMLHttpRequest not working in Mozilla

[payung81]

HI...I'm new in Ajax....i'm trying to retrieve a multiple rss and display it in my browser...it's working fine in IE.....but the request seems cannot be processed in Mozilla....

this is the code that i've written :


function makeRequest(url, div) {

var http_request = false;

if (window.XMLHttpRequest) { // Mozilla, Safari, ...
http_request = new XMLHttpRequest();

if (http_request.overrideMimeType) {
http_request.overrideMimeType('text/xml');
// See note below about this line
}
} 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) {
alert('Giving up :( Cannot create an XMLHTTP instance');
return false;
}
http_request.onreadystatechange = function() { showContents(http_request, div); };
http_request.open('GET', url, true);
http_request.send(null);
}



How can i solve dis problem.?
ty in advance :)
