RE: [PHP] Re: Variable name as a string

The reason why... (I think)
Id defines the element as a part of the DOM - it is the identifier of the
element
Name tells the browser the name of the parameter (i.e. the mane to associate
with the value), not of the element.

PHP and JS are looking for two different things - one wants the element, one
the parameter - so it makes sense (sort of) to use two different terms.

Why???

<form name="my_form" ... >
<input type="checkbox" name="my_checkboxes[]" ... >
</form>

<script language="Javascript">
checkboxes = document.my_form["my_checkboxes[]"];
</script>

Mike:

There is no "Why?", this is just another way to do it. In fact, there
are other ways to accomplish this than what both of us have shown.

What's nice about the technique I described here, at least for me, is
that the "value" attribute applies to both name and id. PHP uses name
and javascript uses id -- it's simple.

However, I've been leaning to using getElementById() to create
unobtrusive javascript, which can be used to isolate and use "name"
as well, thus reducing the html code.

I think my next demo will be to show these various techniques.

Cheers,

tedd
