Insert a CR/LF into a textarea

Question

I've got the following code:

document.onkeydown=function(e) {
if (e.which == 13 && isCtrl) {
   log('Ctrl CR');
} else if (e.which == 17) {
   isCtrl = true;
};

I need to insert a Carriage Return/Line feed where the cursor is located in the input textarea. Now that I think about it, I should probably be using a textarea selector instead of document.onkeydown, but $('textarea').onkeydown doesn't work.

D'oh! Thanks! I'm confused by having to learn js and jQuery together. — Phillip Senn, Apr 15 '11 at 20:44

$('textarea').keydown(function (e){
    var $this = $(this);
    if (e.which === 13 && e.ctrlKey) {
        $this.val($this.val() + '\r\n'); // untested code (to add CRLF)
    }
});

Your solution might add it to the end, but what if the cursor is positioned in the middle? – Phillip Senn Apr 15 '11 at 20:47
Yes, that's definitely a problem. However, there's [information enough on SO already to answer that part](http://stackoverflow.com/questions/946534). – Matt Ball Apr 15 '11 at 20:52
