URGENT JavaScript problem...

[rjlohan]

Hey all.

I have an .asp page in which a form is created by Server-Side VBScript.

In the form I have a set of checkboxes named:

checkbox0
checkbox1
.
.
.
checkboxN

(N can range from about 4 to 10 depending on the creation script)


I need to use JavaScript to verify the form input.

How do I refer to these checkboxes in a for loop?

Is that possible?

eg:

for (i = 0; i < N; i++) {
window.alert(document.form.<B>(checkbox + i)</B>.value)
}


This is a big problem for me right now...

try this:

for (i = 0; i < N; i++) { 
eval("window.alert(document.form.checkbox" + i + ".value) ;");
}

not completely sure, but I think it will work.

[rjlohan]

Excellent!

Cheers dude, you saved me!

I just couldn't figure the syntax. I never would've got it I don't think. I've been fiddling for over an hour now...

[crptcblade]

No problem.

I have tried the same method with radio buttons, but to no avail.

The radio buttons are all called 'radio' but with different values, obviously...

If you had N radio buttons, U have to loop thro' them and find which of them is checked.

for (i = 0; i < N; i++)
{
if (document.form.radio[i].checked == true)
alert(document.form.radio[i].value);
}

Thanks Jem,

I'd forgotten all about the radio[i] property...

It's been awhile..

Hey, not meaning to be rude, but are you following me?

You seem to be the one solving all my problems.

Thanks!

for (i = 0; i < N; i++) {
window.alert(document.form.<B>(checkbox + i)</B>.value)
}

just a quick point rjlohan, you can't but html tags in an alert box!

[JemimaChadwick]

oh boy! Did he mean

for (i = 0; i < N; i++) {
window.alert(document.form.(checkbox + i).value)
} ?

- Jemima.

[JemimaChadwick]

Jus a Mess!!! Pardon.

- Jemima.

[rjlohan]

Yeah, I did Jem, sorry Bob, I'm not that that out of touch.
I just used the wrong bracket when trying to highlight something for my post...
