Specifying a form by name? Problems with document.forms[x]

[Eric]

Hello,

I have code similar to:

if (beforeToday(document.forms[0].sStartDate.value))

that was broken when an include file had a form added to it. Since my
form was no longer the 0th form, my code was broken. Is there any way
to specify a form by name or some other work around for this
situation?

Sure:

<form name="form1">

if (beforeToday(document.form1.sStartDate.value))

Use:
document.forms["form_name"]

Example:
----------
....
<script ... >
function test(){
alert(document.forms["form1"].sStartDate.value)
}

</script>
....
<form name="form1" onsubmit="test();return false" action="#" ...>
<input name="sStartDate" type="text">
<input type="submit" value="Test">
....

</form>
....
---------

that means -
document.forms[formIndex] == document.forms[formNameAsString]

you can use document.getElementById('id') to get any element.
Element used by this method won't uses forms so no problem in
accessing the elements.

You are a reliable source of bad advice, here as elsewhere. Code which
works in some systems but not in others, or which is unnecessarily not
standards-compliant, is not good code.

It's a good idea to read the newsgroup and its FAQ. See below.

Use:
document.forms["form_name"]

<snip>

you can use document.getElementById('id') to get any element.

If and only if that element has a unique ID attribute, or, you are using
a broken browser (namely, IE). Otherwise, just use the forms collection.

Can you name a "system" (OS/browser) where document.formName won't get a
reference to the form as long as the form name doesn't contain illegal
characters? Or, is your anti-McK attitude shining through again?
