JQuery Textarea Alphabetizer

I'm working on a simple alphabetizer however the problem is it doesn't sort it correctly.

$(document).ready(function() var txt = $(".input-text"); $(".alphabetize").on("click", function() txt.val(txt.val().split(" ").sort().join(" ")); ); );

<!DOCTYPE html> <html> <head> <title>Alphabetizer</title> <meta charset="utf-8"> <meta name="viewport" content="initial-scale=1.0"> <meta http-equiv="X-UA-Compatible" content="IE=9" /> <script type="text/javascript" src="http://code.jquery.com/jquery-latest.min.js"></script> </head> <body> <a class="alphabetize" href="javascript:void(0)">Alphabetize</a><br /> <textarea class="input-text" placeholder="Alphabetize your text here...">China India United States of America Indonesia Brazil Pakistan Nigeria Bangladesh Russia Japan Mexico Philippines Ethiopia Vietnam Egypt Germany Iran Turkey Democratic Republic of the Congo France</textarea> </body> </html>

And do you have spaces in that list of countries ?

You should split the text by new lines (n).

n

$(document).ready(function() var txt = $(".input-text"); $(".alphabetize").on("click", function() txt.val(txt.val().split("n").sort().join("n")); ); );

Also. While it's not necessary for your example (as all of the lines starts with capital letter), you should know that .sort() is case sensitive, so that "AbCdEf" will be sorted as "ACEbdf".

.sort()

To make it case insensitive, you can pass a sorting method as argument, where strings .toLowerCase() are compared:

.toLowerCase()

// ... txt.val(txt.val().split("n").sort(caseInsensitive).join("n")); // ... function caseInsensitive(a, b) return a.toLowerCase().localeCompare(b.toLowerCase());

I didn't know sort's case sensitive. Thank you very much bro.
