Copy one to another textbox and change letters

Im using this script to copy from one to another textbox. I dont know how to make when i write in box A that what will be copied in box B to be changed. exp. Letter A ti be 001, letter E to be 002, letter V to be 008. I dont care if its in php or JavaScript.

Thanks for your time and help

Code:

<html> <head> <script type="text/javascript"> function copy_data(val){ var a = document.getElementById(val.id).value document.getElementById("copy_to").value=a } </script> </head> <body> From:<input type="text" name ="a" id="copy_from" onkeyup="copy_data(this)"/><br> To:<input type="text" name ="b" id="copy_to"/><br> </body> </html>

I can't see the logic in the substitution, so I guess you would have to build your own object. If you want it with the leading zeroes...

Code:

<script type="text/javascript"> function copy_data(val){ var subs={"a":"001","e":"002","v":"008"} var b = val[val.length-1]; document.getElementById("copy_to").value+=subs[b] } </script> </head> <body> From:<input type="text" name ="a" id="copy_from" onkeyup="copy_data(this.value)"/><br> To:<input type="text" name ="b" id="copy_to"/><br> </body>

although you would want to have some sort of backup plan for what happens if somebody enters something that isn't one of those letters

just noticed that IE<9 doesn't like that. Better would be this:

Code:

<body> <script type="text/javascript"> function copy_data(val){ var subs={"a":"001","e":"002","v":"008"} var b = val.charAt(val.length-1); document.getElementById("copy_to").value+=subs[b] } </script> From:<input type="text" name ="a" id="copy_from" onkeyup="copy_data(this.value)"/><br> To:<input type="text" name ="b" id="copy_to"/><br> </body> </html>
