Splitting Arrays

[Andi B]

If I have an array set up like so to contain a small code, and the name of
the person to whom the code relates, the values split by a comma:

DMCName[0]="1SC,Andrea Pidgeon"

and I want to be able to return the name when someone enters the code into a
text box, is there a way to split the array and only return the name? -
Bearing in mind that there will be more than one code, and other details
will be included besides the name of the person, and that such a method of
splitting would have to be able to scan through all (roughly 40 entries) in
the array and compare the code to the users entry...

The split() method returns an array:

var splitStuff = DMCName[0].split(/,/);
var userInput = "whatever";

for (var i = 0; i < splitStuff.length; i++) {
if (splitStuff == userInput) {
// you found a match
break;
}
}

If you know the name is always the second thing in the string, you could also do
something like:

if (DMCName[0].split(/,/)[1] == userInput) {
// found a match
}
