convert variable to a value

[Cogswell]

i have a quick ? i have a variable that is named dynamically by
combining values into a string, how would i then get the value of the
string

formname = "document.f orm" + count + ".quantity.valu e"


I then need the value of the form element, not the value of the
variable (formname).

anyone?

Do you also have a Shift-key?

formname = "document.f orm" + count + ".quantity.valu e"
var theValue = eval(formname);

However, given the general dislike of 'eval', I would propose the
following:

var formname = 'form' + count;
var theValue = document.forms[formname].elements['quantity'].value;

Have fun.
