JavaScript, Multiple XML file loading problem, FF/IE

[psybert]

Hello everyone,

Long time lurker, first time poster. I'm a beginner coder, and I've taught myself everything with the help and expertise of users and websites like this one. I normally figure out any problem, but this one really has me stumped.

Basically, I have created a site that initially loads a set of "items" and their values into 17 drop down menus from an XML file. Each of those "items" when selected from the drop down menu loads data into a few arrays, and outputs it to a table. The data is then used for a calculation output, which is the overall goal of the program/site.

Everything works fine up to this point...

Now I'm introducing a button that automatically selects the 17 "items." So basically my application runs through a loop and is supposed to: select each item, load each XML file, interprets each "items" data, save each "item" data to arrays, and then outputs each to the table.

It works fine locally with internet explorer 6, but does not work with Firefox online/local, or IE online. If I add an "alert" somewhere in the loop process, it works, but then I have 17 alerts to deal with. IE online only inputs the last item in the table, and Firefox outputs all 0's locally, and then online Firefox implements mostly all zeros, except for the last and first(which outputs the data of the last instead of the first).

So anyway, my source code is about 2000 lines. You can access my program at http://www.stasistech.com/wow/test/itemdps.html (click the max "i.lvl" button to see the problem)

Here's the code that somewhere has the problem(i hope!):

itemSlots=new Array();
itemSlots[0]="head";
itemSlots[1]="shoulders";
...
itemSlots[16]="relic";
 
//called by the button to select gear
function selectGear(gear)
    {
    switch(gear)
        {
        case "lvl":
            for (j0=0; j0<itemSlots.length; j0++)
                {
                document.itemForm.elements[itemSlots[j0]].selectedIndex = 1;
                loadItem(document.itemForm.elements[itemSlots[j0]],itemSlots[j0])
                }
            break;
        }    
    }    
 
//loads each item, ignore the unlock step
function loadItem(itemID,slot)
    {

    if(itemID.options[itemID.selectedIndex].value =="7")unlockSlot(slot); 
    if(unlockItemFlag==0)lockSlot(slot);
    //loads file for each item
    var xmlFileLocation = ('items/'+itemID.options[itemID.selectedIndex].value + '.xml')

Thanks in advance for your help,

Anyone have any guidance on what I should do? I've sort of hit a brick wall in the site programming until I can figure this problem out. Any help or direction would be greatly appreciated. Thanks again for your time,

Bump~ ! I figure it's the weekend, maybe It will get some more visibility.

All I can add is that there are 132 HTML errors and no doctype so IE is in quirks mode.

I went in and fixed all of them. Thanks for the tip. Unfortunately the page still doesn't work :(

If it works offline, but not online, maybe you're accessing the file incorrectly.

And if your code doesn't work at all in Firefox, then the code that you've specified in your FF branch is probably incorrect.

The problem only comes about when i try to loop the whole process. If i change and add each item manually it comes up fine. In fact if I add an "alert" in the loop process, it slows it down enough to actually work.

anyone have any more ideas? :(
