AJAX Not Working In Firefox

[Danny R]

I have the following javascript which works in either IE or Firefox but
not on both.

When I set the code to

http_request.open('POST', url, true) - Works in IE only
http_request.open('GET', url, true) - Works in Firefox only; Does not
refresh in IE.

How do I resolve this?

Thanks in advance.

function makeHttpRequest(url, callback_function, return_xml)
{
var 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) {
alert('Unfortunatelly you browser doesn\'t support this
feature.');
return false;
}
http_request.onreadystatechange = function() {
if (http_request.readyState == 4) {
if (http_request.status == 200) {
if (return_xml) {
eval(callback_function +
'(http_request.responseXML)');
} else {
eval(callback_function +
'(http_request.responseText)');
}
} else {
//alert('There was a problem with the request.(Code: ' +
http_request.status + ')');
}
}
}
http_request.open('POST', url, true);
http_request.send(null);
}

Guestion why don't u use prototype? pretty easy and it work's in every
browser.

http://wiki.script.aculo.us/scriptac...show/Prototype

example:
new Ajax.Updater('mydiv', '/foo/bar', {method:'post',
postBody:'thisvar=true&thatvar=Howdy', asynchronous:true,
evalScripts:true});

evalScripts on the end means that when the ajax page you are calling
contains for example <script>alert('hello');</scriptit will execute
that the other stuff just echo't will be outputted to mydiv.

i give you this because i stoped using my own crap because this stuff
is alway's working

Hope this helps

another thing...

stuff like this:
document.getElementById('ajax-latestphotos').innerHTML = html_content;

will become this:
$('ajax-latestphotos').innerHTML=html_content

Thanks for the response.

However, any of you guys know why this isn't working on both browsers?
Is there an alternative code that works on both?

Danny R напи�ав:

if (return_xml) {
eval(callback_function +
'(http_request.responseXML)');
} else {
eval(callback_function +
'(http_request.responseText)');
}

You can use http_request.responseXML only for appointed content type:

var respType = http_request.getResponseHeader("Content-Type");
if (respType == 'text/xml')
{
// process http_request.responseXML
}
else
{
// process http_request.responseText
}

Does not refresh in IE.

It may be caused by caching.
Simple solution were posted here

Instead of
var url = '/ub/apps/ajax/latestphotosxml.aspx';
use
var url = '/ub/apps/ajax/latestphotosxml.aspx?'+ Math.random();
