Javascript Form Submission Variables

[Captain Midnight]

Hi Everyone! This is a great forum by the way..

Anyway, I have a PHP script, that gathers some basic information from a database and pre-populates a form for a user. The HTML that's generated looks something like this (to be brief):

Source (with PHP variables) for the Submit looks something like this:

<img src="/images/disk.gif" height="24" width="24" alt="Save" onclick="document.dnsform.edit['.$jsiter.'].checked=true; processsingle('.$jsiter.');">
 

HTML Source After Execution:

<img src="/images/disk.gif" height="24" width="24" alt="Save" onclick="document.dnsform.edit[0].checked=true; processsingle(0);">
 

Source Input:

<input type="checkbox" name="edit['.$jsiter.']" id="edit" value="'.$row->ident.'">
 

HTML Results (view source):

<input type="checkbox" name="edit[0]" id="edit" value="258">
 

I'm trying to grab that "258" value out of the "edit[0]" variable within Javascript.

This is what I've got so far and it doesn't work. :(

(to be brief, I'm just trying to alert the user of the variable to make a simple exmaple)

var params = encodeURI ( ( 'edit['+idx+']' ) );
alert(params);
 

I would have expected an alert box with "258" in it, but it's no good. Is this more complicated that what I'm making out to be?

Thanks,
CM

hi ...

to retrieve the value of the following input-field:

[HTML]<input type="checkbox" name="edit[0]" id="edit" value="258">[/HTML]
simply use:

var field_value = document.getElementById('edit').value;

kind regards
