simple javascript question

Can you declare a variable and have the name be a concatenation? Similar to this...

var 'total'+ product = product * number;

You'd have to use array/object notation.

var foo=new Array();
foo['total' + product] = product * number;

or, if you are okay with having global variables.

window['total' + product] = product * number;

most often though, you'd just use an array...

total=new Array();
total[product] = product * number;

Thanks, but the catch is that the problem asks that I dont use arrays. This is a class I took as an elective for the hell of it, didnt buy the book, and now wanna get over with...

I guess i cant do it the way i had thought, so it will have to be much sloppier

eval("var total" . product . "=" . (product*number));

eval() puts into JS code the string you pass it (meaning it interprets the string as if it were actual code).

Sweet thanks a ton.

Just don't ever use eval like that in actual practice. Eval is the javascript equivilent of goto - occasionally needed, but generally disliked due to how easy it is to abuse it and produce slow ugly code.
