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.

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(). Unfortunately IE says "unexpected call to property or method access" for the second to last line of my function. If you know what I've done wrong or how to fix it I would appreciate the help.

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);
