Incrementing all VALUE attributes 1

[Arzo2000]

Hi all,
I have a lot of checkboxes on a form and I would like to set a unique value to their VALUE attribute. So basically what I am after is a script that parses through all <INPUT> tags of TYPE "checkbox" and sets the VALUE attribute to a unique number (I suggested that it would be incremented).

Here is an example of what I am after:
Before:

<INPUT ID="chkOption1" TYPE="checkbox" VALUE="checkbox" />
<INPUT ID="chkOption2" TYPE="checkbox" VALUE="checkbox" />
<INPUT ID="chkOption3" TYPE="checkbox" VALUE="checkbox" />

After:

<INPUT ID="chkOption1" TYPE="checkbox" VALUE="1" />
<INPUT ID="chkOption2" TYPE="checkbox" VALUE="2" />
<INPUT ID="chkOption3" TYPE="checkbox" VALUE="3" />

Thanks in advance guys.

1) get a collection of form elements:

var myElems = document.forms['myformname'].elements;

2) set an initial index:

var intIndex = 1;

3) loop through all elements. if it's a checkbox, set the value then increment the counter:

for ( var i = 0; i < myElems.length; i++ ) {
    if ( myElems[i].type == 'checkbox' ) {
        myElems[i].value = intIndex;
        intIndex++;
    }
}
