multiple checkbox question

[bjnst6]

hey there...

i'm using IE 6...and i've got this javascript code:

var totalCheck = theForm.chkDelete.length;

alert(theForm.chkDelete.value);
alert(theForm.chkDelete.length);

okay...now i have this html on the page:

<input type="checkbox" name="chkDelete" value="#EventID#">

instead a cfoutput loop...so in a loop.

now when i have 2 or more checkboxes on the page it works fine...i get

chkDelete.value = (whatever the first EventID is)
chkDelete.length = 2

but when i have only one checkbox the .value works the same...but the length is undefined.

what's going on here and how can i test for just one box if it won't work this way?

thanks!

I'm assuming all of your checkboxes have the same name??

If so, they are referred to as indices in an array - chkDelete[0], chkDelete[1], etc.

The length property defines how many members are in the array.
When there is only one checkbox, the length is undefined because there have to be at least 2 members in any array in JavaScript.

For the special case of one checkbox, simply do:

if (theForm.chkDelete.length) {
// code for 2 or more checkboxes
for (i=0; i< theForm.chkDelete.length; i++) {
foo = theForm.chkDelete[i].value;
alert(foo);
}
} else {
// code for 1 checkbox
foo = theForm.chkDelete.value;
alert(foo);
}

this is what i was thinking you'd say...i just couldn't find any documentation on it for sure. sounds like a good fix.

i should've know the websmith would know...again. thanks!
