Function in JS, ONE line of code

I have a very simple function written in JS ( JavaScript) used to convert a transformed variable into a readable value on the fly called Show-Original. The process is INCREDIBLY simple: 1- a string variable is assigned a string value (transformed text) 2- a for loop goes through the variable character by character converting each character into it's original value using 2 standard js string functions. I want to revert this function, to one that takes a variable with regular text and creates the transformed value. We are talking about one function that uses only ONE, yes only ONE line of code in JS. Then I want to create a VERY simple form that will let me type a text, and convert it to a changed type text. On the other hand, another option will let me type a changed value to get the original back in the same form. [login to view URL] shows the format. You wonder if it is so simple why I don't code it myself if it is only one line of code, plus the form? Well, I do not know JS and I need it TODAY ! If you know JS, the whole work shouldn't take more than 30 minutes. I think that this work shouldn't be more than $10,and you will get a new star in your Provider rating ! I will PM a ZIP file with code and Form to use function in to candidates that can prove knowledge in JS. If you have to take 2 days to do it, or if you do not know JS, just Don't bid. The candidate should bid and once I assign the work, it should be returned done in a couple of hours, at the most in half a day. As usual, by downloading the file, or placing a bid, you accept under international (and US) copyright that the code and usage of this function / form belongs only to me, that you cannot use or show this code anywhere else under any circumstance, and you will be a ghost code writer in this case. thank you
