Javascript: Using A String As A Variable

Javascript Comments »
I have a function that I send a javascript array to like so:

if (VAR_clicked == "one") {
} else if (VAR_clicked == "two") {
} else if (VAR_clicked =="etc") {

My problem now is I have many more arrays and want to do something like this:

FUN_Table("VAR_array_" + VAR_clicked);

I’m trying to use a string to pass a variable to the function, this does not work.
Any ideas as to how I can do this?

This doesnt return a result since findthis is being interpreted as text rather than a variable. I want its contents to be inserted into the regex expression.
