Problems with XmlHttpRequest Object: readystate won't go past 1

[hype]

Hey everyone !

I've been programming for some years now, but only recently have i started adopting the AJAX techniques. Right now i have implemented an AJAX based login system and i want to implement a "menuLoader" of some sort, so that each time a user logins it will also refresh the menu. Usually this wouldn't be much of a problem but with AJAX it's different

Code: Select all

function getPermissions() 
{		// only get a seed if we're not logged in and we don't already have one
		if (!hasPerm && http_menu) {
			try{
				// open up the path
				http_menu.open('GET', MENU_PREFIX + 'task=getperm', true);
				http_menu.onreadystatechange = function(){
				handleHttpGetPermissions();};
				http_menu.send(null);
			} catch(e){
				perm_id = 'Could not connect to server.';
			}
		}
		else 
			perm_id = 'Could not create the HttpXml object';
}

function handleHttpGetPermissions()
{			
	// if there hasn't been any errors
	if (http_menu.readyState == NORMAL_STATE_MENU) {
		// split by the divider |
		results_menu = http_menu.responseText.split('|');
		if(results_menu[0] == true){
			// perm is the first element
			perm_id = results_menu[1];	

			// now we have the perm
			hasPerm = true;
		}
		
		else if(results_menu[0] == false){
			perm_id = 'results_menu[1];
		}
		
		else{
			perm_id = results_menu[0];	
		}
	}
	
	else{
		perm_id = http_menu.readyState;
	}

}

The actual object is loaded in a global variable.

Code: Select all

var http_menu = getHTTPObject();

This uses a function from a seperate file I use just to create the XmlHttpRequest Object. This work's fine in my login system, so i don't see any reasons for it not to work in this situation, but the fact is that the readyState won't go pass 1!! The loadMenu function is called at a eventlistener which i use to call the login funtion so there shouldn't be a problem there...

Can anyone tell me what's wrong here?

PS: In this code the perm_id variable is suposed to be used to hold the permission level of the user but i ended up using it to transport other messages just to check out what's happening so don't be offended by it

well, readyState can be 0:uninitialised, 1:loading, 2:loaded, 3:interactive, 4:complete.
If you're not going past 1, then check the URL of the request (ie.: MENU_PREFIX)

I recommend you test Ajax apps in Firefox with Firebug.
