Dynamic object names

[DogBot]

I know so little about javascript that I can't even articlulate the question properly. So, instead here is what I am trying to do.

[CODE=javascript]
var i = document.myform .myselectfield. selectedIndex;
var sel = document.myform .myselectfield. options[i].text;
var i=0
while (i<=9)
{
eval("document. xform" + i + ".custom.value" ) = sel;
i=i+1
}[/CODE]

The problem is with line 6. I am trying to dynamically assign a value to a field in a series of forms named xform1, xfrom2....xform 9

Welcome to TSDN.
[code=javascript]
eval("document. xform" + i + ".custom.va lue= "+sel);
//try this
[/code]

Best of Luck.

Kind regards,

eval is evil! Avoid wherever possible.

Try:[CODE=javascript]document.forms["xform"+i].custom.value = sel;[/CODE]

yep ... don't use eval ... there is no need to use eval besides to evaluate a json-string or something like that ... that might be the result of an ajax-request for example ...

kind regards

Learned a lot with just this question!!!

Eval in all languages is evil, but it is always good to know how it works,

The first response answers my question exactly as I posted it and shows me how to properly use eval..thank you.

I will be using the non-eval sample however as you all recommend.

Thank you all very much.

Glad to hear you got it working. If you have any more JavaScript problems, you know where to come.
