This is a simple substitution cypher [not real encryption!] which will be cracked in less than 10 minutes...
Having said that. Here's the incomplete JS code:

for (x = 1; x < tmpMessage.length; x++) { //for each char input text
for (i = 1; i < alpha.length; i++) {
if substring(tmpMessage, x, 1) = substring(alpha, i, 1) {
encMessage = encMessage + substring(crypt, i, 1) //replace the char with the corresponding crypt char
}
}
}
