Why is javascript not working correctly in Firefox

[rkoya]

Hi,

I am having trouble with Javascript not being displayed in Firefox but displays fine in IE. This is the javascript code I am trying to get to work:

function populateDestination (destdisplist, destvallist) {
document.details.area.length=1;
var newElem;
var selectedItem = 0;
for (var i = 0; i < destdisplist.length; i++) {
newElem = document.createElement("OPTION");
newElem.value = destvallist[i];
newElem.text = destdisplist[i];
document.details.area.add(newElem);
if(newElem.value=="107") {selectedItem = i + 1;}
}
if (selectedItem!= 0)
{
document.details.area.options[selectedItem].selected = true;
listoffices(document.details.area.options[selectedItem].value);
}
}

Can anyone help?

Good day rkoya. It could be because Firefox uses "nodes" or "Childe windows". And when you declare something via script, FireFox must know which window to target.

I'm afraid I can't offer much for a solution. Though I recall something about (/*Node*/ root) declared next to the function name.... not sure rkoya.... :(

Maybe something like this instead:

function populateDestination (destdisplist, destvallist) {
var areaOptions = document.details.area.options;
document.details.area.length=1;
var newElem;
var selectedItem = 0;
for (var i = 0; i < destdisplist.length; i++) {
newElem = new Option(destdisplist[i],destvallist[i]);
areaOptions[areaOptions.length] = newElem;
if(newElem.value=="107") {selectedItem = i + 1;}
}
if (selectedItem!= 0)
{
areaOptions[selectedItem].selected = true;
listoffices(areaOptions[selectedItem].value);
}
}

Hey good idea. Just pop that in a variable maybe then FireFox won't misplace the data :D Good thinking!

Actually, the difference is that this creates a new Option object vs. creating an element in the DOM. I think I read somewhere that trying to add options via the DOM doesn't work, but the new Option approach should.
