[Javascript] Something better than getElementById

[Terry Riegel]

Paul,

Thanks for your answer. It is very helpful.

I am starting to recraft my pages and need a good tutorial on parsing  
stings with javascript for someone with a heavy background in BASIC  
style programming and very little understanding of Regular  
Expressions. Any ideas?

Here is a BASIC style instruction I need to convert to Javascript

a="nor pri"
b="sel"+right(a,length(a)-3)

RESULT:
a="nor pri"
b="sel pri"

Thanks for any help.

Terry
