How to refer to DHTML objects using a variable name

[PGTips2]

This one has me stumped and I hope someone knows the answer.

I am reading a number of records from a database and building up a list of products on an ASP Page.

As the code that generates each line of the list is in a Server Side loop I am naming each field using the ID of the record from the database:

IE:
<Input type &quot;Checkbox&quot; name=&quot;Instock1&quot;>
<Input type &quot;Checkbox&quot; name=&quot;Instock2&quot;>
<Input type &quot;Checkbox&quot; name=&quot;Instock3&quot;>

I have a link on each line that calls a client side VBScript function to dynamically check this box. It passes the ID to the function so it knows which one to check.

A part of my function looks like this

Function CheckBox(intRecordID)
strObjectName=&quot;InStock&quot; & intRecordID
...
End Function

So I have a variable that contains the name of the object I want to check but the line:
frm.strObjectName=Checked

doesn't work.

How do I tell the browser to look at the object whose name is contained within the string strObjectName?

I've looked everywhere for some kind of conversion/eval function but with no success.

Anyone know how to do it?

eval(strObjectName) or else it doesn't find it's a variable ------

I'm not sure that -

eval(strObjectName)

will work, but I do know that if your clients have IE 5 or higher, you can use this -

Function CheckBox(intRecordID)
strObjectName=&quot;InStock&quot; & intRecordID
Execute &quot;frm.&quot; & strObjectName & &quot;.checked = true&quot;
...
End Function


but if they don't necessarily have IE 5, then you can put an inline script with each button if that is possible... &quot;A computer scientist is a person who knows when it is time to hit the computer.&quot;
