[Javascript] IE work-a-round question (re: checkboxes)

[Claude Schneegans]

 >>It is a quick and easy way to get at the characters you want from the 
string.

substr and substring are the appropriate way of doing it.

 >>Only if there is a bug in the JavaScript engine. The data type is string

Actually, Javascript is a typeless language. In C you would be right, 
but not with Javascript.
Sometimes types are guessed by the Javascript machine, and sometimes, it 
does not
guess it the way you would expect.
