How do I reference elements in Layers in NN

martindavey · Feb 21, 2001

I have created several layers on my page.
In each layer is a form.
I am trying to reference the elements on those forms without success.
Example.

<body onLoad="document.layers.layer1.Page1.FirstName.focus();">

<layer id="layer1">
<form name="Page1">
<input type="text" name="FirstName">
</form>
</layer>

This gives me the error:
document.layers.layer1.Page1 has no properties.

I've tried:
document.Page1.FirstName
document.layer1.FirstName
documents.layers.layer["layer1"].Page1.FirstName
etc.

Any ideas??????

documents.layers["layer1"].Page1.FirstName

Try this

document.getElementById('name').

iza's solution works in just Netscape. Mine is cross browser compatible. Use whatever you need.

TGWW, your "cross browser" is only for IE and Netscape6.

to martindavey:
REAL cross browser should combine both
document.getElementById('name')
and
documents.layers["layer1"].Page1.FirstName

to use this you should also put your <layer> inside <div>.

i don't really think "layer" is a cross browser element - or is it ??

No, it isn't. But it's the only way to maintain control over "layers" of content in NN4.x
Unfortunately...

Thanks for the help guys BUT...
Please confirm that I'm a complete stupid arse...
I've tried the following 3 commands as an experiment:

1. ...onLoad="document.getElementById('FirstName').focus();">

2. ...onLoad="documents.layers["layer1"].Page1.FirstName.focus();">

3. ...onLoad="documents.layers.layer1.Page1.FirstName.focus();">

I get the following 3 errors respectively:

1. document.getElementById is not a function.

2. syntax error.
documents.layers[
................^

3.documents is not defined.

Sorry for acting the fool!!!

PS. I'm using NN4.6

OK martindavey, here's some info for you:

1. Concerning your last posts:
a) As far as I know, getElementById functoin was implemented only in Netscape6, so it's no wonder that you get an error.
b) >> syntax error: documents.layers[
"document" should be without "s" at the end.

2. About your problem (remember what all this started from?):
This is taken from Netscape's Developer Guide:
"Each layer object contains its own document object."

So, in order to access element placed on a layer you have to use this expression:
document.["layername"].document.<element>

where <element> is an element that you want to access, like Page1.FirstName that you asked about. Sounds illogically a little bit, but that's the way it is.

Remember that LAYER tag is for absolute and ILAYER is for relative positioning only.
And that they work only in NN4.x!
As I stated before, in order to create script compatible with Netscape6 you should duplicate everything using
document.getElementById('name')
Hope it will solve your problem at last!

Indeed you are correct.
I have success at last.

I discovered this for myself only yesterday from an example on this site, you have confirmed this for me.

Many thanks for everybody's help on this one.
