Question

I have this code

I use jkey to simplify the usage on detecting which key is pressed.

Question
What i want is when any other except up arrow key is pressed set the value of count to -1 and if up arrow key is pressed do it just like in the code.

Is there a way out by using the jKey plugin ?
if not then how do i do it with normal jquery

This obviously doesn’t get you exactly where you want to go but it should get you started.

HTML

<textarea id="myBigText"></textarea>

JS

$(document).ready(function() {
    $("#myBigText").keydown(function(evt) {
        evt = evt || window.event;
        var charCode = evt.which || evt.keyCode;
        if(charCode == 38) {
            alert("This is the up arrow key");
        } else {
            alert("This is not the up arrow");
        }
    });
});
