eval() not working in firefox

Hello Everybody,

I have the following lines in my code

1)
totalElements=eval("document."+formname+".RCBillin gCycle"+totalRCRows+".length")

2) var newoption=new Option (BillingCycleName,BillingCycleId);
eval("document."+formname+".RCBillingCycle"+totalR CRows+".options[totalElements]=
newoption");

In both statements above, the eval code doesnt work in firefox. Is
there a workaround?

Regards,
Angel

No workaround is needed as there is no need to use - eval - at all and
it is more likely the shortcut property accessors that is not working
in Firefox.

Replace:-

eval("document."+formname+".RCBillingCycle"+totalR CRows+".length")

-with:-

document.forms[formname].elements['RCBillingCycle'+totalRCRows].length;

- and replace:-

eval("document."+formname+".RCBillingCycle"+totalR CRows+
".options[totalElements]= newoption");

-with:-

document.forms[formname].elements['RCBillingCycle'+
totalRCRows].options[totalElements]= newoption

Implemented the code. Got the following error

document.forms[formname].elements['RCBillingCycle'+totalRCRows] has no
properties

Please don't top post here, reply below a trimmed quote.

That will return a reference to a form with a name attribute value equal
to the value of - formname - and an element with a name attribute equal
to the value of - 'RCBillingCycle' + totalRCRows -.

e.g.:

<form name="formA" action="">
<input type="text" name="RCBillingCycle0">
</form>

<script type="text/javascript">

var formname = "formA";
var totalRCRows = '0';

// Wrapped for posting
alert(typeof
document.forms[formname].elements['RCBillingCycle'+totalRCRows]
);

</script>
