Dynamically name form fields

Hello,

I need to populate the value of a dynamically generated form
field name.  But wrapping in an eval() does not work (at
least the way I'm doing it).  Can someone show me how to
properly do this?  Everything works fine down to where I try
to assign the value of "cellPhone" to the
dynamically named form field (the 'eval' line).

function putCell(ct) {
	var AC =
eval("document.CFForm_1.cellA_"+ct+".value&qu
ot;);
	var PX =
eval("document.CFForm_1.cellP_"+ct+".value&qu
ot;);
	var SX =
eval("document.CFForm_1.cellS_"+ct+".value&qu
ot;);
	var cellPhone = AC+"."+PX+"."+SX;
       
eval("document.CFForm_1.document.CFForm_1.phoner_"
+ct+".value") = cellPhone;
	document.getElementById('a11_'+ct).innerHTML = cellPhone;
	document.getElementById('a11_'+ct).style.visibility =
'visible';
	document.getElementById('a12_'+ct).style.visibility =
'hidden';	
}

Thanks,
Dave

You don't need eval, just use your form like a hash instead
of trying to get the values like a property:

var AC = document.CFForm_1["cellA_"+ct].value

Oh, and to address the original post's concern, yes, that
method works in assignment as well... either of these two
are valid:

var AC = document.CFForm_1["cellA_"+ct].value
document.CFForm_1["cellA_"+ct].value = AC;

And, since the key value is dynamically created using
whatever formula, you could even use form values (or even
dynamically addressed form values) as part of the field
name:


document.CFForm_1["cell"+document.CFForm_1.phonety
pe.value+"_"+ct].value = cellphone;
document.CFForm_1["cell"+document.CFForm_1["p
honetype_"+ct].value+"_"+ct].value =
cellphone;

of course, if you get crazy with the document.CFForm_1
assignments, it pays to do:

var theForm = document.CFForm_1;

first, to make things less hair-pullingly confusing.
