howto access form key value?

Candyb · Nov 23, 2001

Hi,

if i had a form name='list':
<input name='box' type='text'>blah</input>
<input type='submit' name='hello' value='3' >
i know that you grab the value by
document.list.box.value = blah
but what if you want to access hello?
document.list.key? or document.list.key(2) is wrong...
my form only has two elements, a text and a submit.
my submit's name is built dynamically. (aside from the point)
I have many submit buttons but the form only has 2 elements.

Is it possible to grab that name?

Thanks,
Candy

Huh?

How is the name built dynamically?

And normally your referenced elements ought to have an ID property... which I think most browsers will default to the same value as the name but it isn't trustworthy.

You ought to have something like:

<form id='list' name='list'>
<input id='box' name='box' type='text'>blah</input>
<input id='hello' name='hello' type='submit' value='1'>
<input id='hello' name='hello' type='submit' value='2'>
<input id='hello' name='hello' type='submit' value='3'>
</form>

You normally reference the ID in script. This eliminates most possibilities for confusion.

So you have things like:

document.all.list.hello(2).value = x

For example:

<html>
<head></head>
<body onload="document.all.list.hello(2).value='Hey!'">
<form id='list' name='list'>
<input id='box' name='box' type='text' value='blah'>
<input id='hello' name='hello' type='submit' value='1'>
<input id='hello' name='hello' type='submit' value='2'>
<input id='hello' name='hello' type='submit' value='3'>
</form>
</body>
</html>

Usually you can abbreviate a bit:

<body onload="list.hello(2).value='Hey!'">

By reusing the name value multiple times you create a collection, which can be indexed (base 0, run the above example and the 3rd button gets "Hey!" - NOT the 2nd one!).

Also, <input type=text> is NOT a block tag. You must be thinking of <textarea> ? There is no </input>.
