I'm making a script and I seem to be getting this error:

Error: uncaught exception: [Exception... "Index or size is negative or greater than the allowed amount" code: "1" nsresult: "0x80530001 (NS_ERROR_DOM_INDEX_SIZE_ERR)" location: "***"]

I have looked on google for an answer, and lots of people seem to be getting this error, but noone seems to know what causes it.

Anybody here have any ideas about it?

}
This functions is called upon in the function above
Code: 
function nullOptions(w,menu){
	//superman
	alert(menu.options[menu.selectedIndex].value);
	var tot=menu.options.length;
	for (i=0;i<tot;i++){
		menu.options[i]=null
	}
	menu.options.length=0;
}

wow, good times.

do you have a link? this code isn't exactly friendly to read.

what does this do?

Code: 
    for (i=0;i<tot;i++){
        menu.options[i]=null
    }
    menu.options.length=0;

you should be able to just do this:

Code: 
menu.options.length = 0;

without that loop.

It doesn't say the error line. (well it just says the line that the javscript starts at, not any line in particular). I really doubt that this is an error with syntax, but I'm pretty sure that it has to do with something with something that the javascript is not able to do or something like that.

As for your previous post, that code is to take all the options off of a drop-down menu to make way for options that will be added in the addWorkout() function.

a) you have failed to provide us with any manageable testing harness. the code you provided cannot easily be copied/pasted without rework.

b) having these back-and-forth conversations without providing a link or any specific information makes it hard, if not impossible, to debug your 120+ lines of code with our eyes.

c) as stated in my previous post, your loop is unnecessary - simply setting the length to 0 will do the trick.

Ya it's because I mainly just wanted to know what the error meant, so I could change the code accordingly. I could give you everything, but it is very long, and I doubt anyone would want to go through the whole thing.

the error basically means you're trying to reference something out of range.

for example, you might get this error if you have a select box with three options:

Code: 
<select name="s">
  <option value="1">1</option>
  <option value="2">2</option>
  <option value="3">3</option>
</select>

but you then try to reference an out-of-bound option:

Code: 
document.forms['myFormName'].elements['s'].options[6].selected = true;

since there is no 6th option, this would error out.

Thanks a lot, that makes sense.

sorry, sometimes i get too into the "give me the code and i'll tell you what's wrong" mode, instead of the "that error means this" mode. most people like to have everything handed to them, rather than understanding the problem and finding the solution on their own.

kudos.
