eval() not working in firefox

Hello Everybody,

I have the following lines in my code

1)
totalElements=e val("document." +formname+".RCB illingCycle"+to talRCRows+".len gth")

2) var newoption=new Option (BillingCycleNa me,BillingCycle Id);
eval("document. "+formname+".RC BillingCycle"+t otalRCRows+".op tions[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+".RC BillingCycle"+t otalRCRows+".le ngth")

-with:-

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

- and replace:-

eval("document. "+formname+".RC BillingCycle"+t otalRCRows+
".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="RCBilling Cycle0">
</form>

<script type="text/javascript">

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

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

</script>

Hello. I have always thought that the eval() function was very flexible and useful. If I use it, I can define functions at runtime!! However, I have found a case where eval() does not work properly. It works, for example, when invoking functions (alert('hello')), but not for defining functions. The case occurs when retrieving the javascript code with

I have some complex logic which is fairly simply to build up into a string. I needed a way to Eval this string and return a Boolean result. This code works fine to achieve that goal.

This code executes pretty frequently (maybe 4 times per transaction) and...

Hi, I have tried the following based on suggestions of the best way to insert JavaScript into a page. This is instead of using eval().

Hey, Im at my wits end! Im trying to get IE to store a string that defines a multi-demensional array as an actual array. Heres what the array definition would look like: foo = Array( {'key' : 'value', 'key2' : 'value2'},{'key' : 'value', 'key2' : 'value2'}, {'key' : 'value', 'key2' : 'value2'}, {'key' : 'value', 'key2' : 'value2'}); alert(foo);
