Another Javascirpt question... looping through arrays

[Superwormy]

for (var key = 0; key < formobj["category[]"].length; key++) {

var thingama = formobj["category[]"][key];
alert ("it is: " + thingama);

}


Thats what i have... it doesn't work. Basically theres a multiple select box named category[] in an HTML form, the form is passed to javascript with an onsubmit="return FunctionName(this)"

All I want to do is loop through that category array and print out the values... how?

What is your form name?

for (var key = 0; key < document.{your form name that the form element belongs to}.category[].length; key++)

Right but the actual name of the array is category[], INCLUDING those brackets.

And 'formobj' is what the function takes as the array. It loops through the correct number of times, but I don't know how to refer to each value for each selected thing.

That make sense?


What I really would like is a statement like the foreach ($arrayname as $key => $value) { like PHP / Perl has... does Javascript have this?
