[RESOLVED] eval() of a concatenated string

[wmhop]

I have the following segment of js, which works in firefox:

for (question = 1; question<=8; question++){

    for (i=0;i<document.forms[0].eval("fundDispSkills"+question).length;i++) {
        if (document.forms[0].eval("fundDispSkills"+question)[i].checked) {
            passFailScore = passFailScore + parseInt(document.forms[0].eval("fundDispSkills"+question)[i].value);
			number_of_questions_answered = number_of_questions_answered +1;
        }
    }	

}

but the eval("fundDispSkills"+question) part is not allowed in ie.

What I need to do is find a different way to get fundDispSkills+question to evaluate to the name fundDispSkills1, fundDispSkills2, fundDispSkills3....etc.

I tried just concatenating "fundDispSkills"+question but both firefox and ie give me errors.

Any ideas?

Perhaps wrapping the whole condition in an eval() might work?

if(eval("document.forms[0].fundDispSkills"+question+")[i].checked"))

Or perhaps even:

if(eval("return document.forms[0].fundDispSkills"+question+")[i].checked"))

Or

if (document.forms[0]["fundDispSkills"+question][i].checked) {

See, I'd remembered doing that before... but I didn't know how browser-compatible that code was... never tested it thoroughly before (it worked in FF, so that's all that mattered for me at the time :p).

thanks weedpacket, it worked in ie7 and firefox. thanks for the suggestions brad i had actually tried the first suggestions in my many failed attempts previously. i never did try the second one though so i'm not sure if it works or not.
