This.form.name not working!

Hello all
Sorry to post what may be such an obvious or schoolboy problem but I can't see why this simple code works on one website I wrote, but not another!

PHP Code:


		
			
echo "<form method='post' name='customer' id='customer'>";

        echo "<a href='#' onclick='alert(this.form.name);'>select all</a> <br />";

    echo "</form>";

When I click on the 'select all' link, nothing happens; if I change it to alert 'this.form', I get "undefined" but as you can see, I have named and ID'd my form!
I have searched google and the syntax etc all appears to be correct (and as I mentioned above, I have used this code on other websites without problem).

Does anyone have any suggestions please?!

Sure ...

PHP Code:


		
			
<!DOCTYPE html>

<html>

<head>

</head>

<body>

<?php

echo "<form method='post' name='customer' id='customer'>";

        echo "<a href='#' onclick='alert(this.form.name);'>select all</a> <br />";

echo "</form>"; 

?>

</body>

</html>

I was trying to add a Select ALL / NONE / Toggle to an existing page and when it decided not to work I wrote that code to test the code without any external "interference" and discovered that it refused to work when there was nothing else going on!

I've also viewed page source and copied that into "newfile.html" (in effect dropping all PHP) and it still refuses to work!

For what it's worth, here's the "view source" from the above PHP ...

Code:

<!DOCTYPE html>
<html>
<head>
</head>
<body>
<form method='post' name='customer' id='customer'><a href='#' onclick='alert(this.form.name);'>select all</a> <br /></form></body>
</html>

That seemed like a very eye-rolling "sure"

I wanted to see the document type and charset.
An anchor is not part of a form so it cannot reference a form as a form element ~~parent~~ child. It can be referenced as a parent node.

this.parentNode.name

this.parentNode.name

I see, ok yes, that makes sense now!

As for the 'sure ...' haha well the code I had posted was the entire page at the time of posting, I later added the rest of the HTML to see if that would make a difference ... apparently not.
I'm on with something else now though but when I revisit the select all / none / toggle, I will use a button.

ps. With regards to nicking the line from other code, I re-checked the original source and the onclick was taken from a submit button, doh

THANK YOU for the reply and assistance, it's very much appreciated!
