Capitalize first character of user input in real time with JQuery

Question

I am trying to auto-capitalize the first character of a textarea/input that the user inputs. The first attempt looked like this:

$(document).ready(function() {

Here is a fiddle I made that does what you want in Chrome. I'm not sure if it will work in other browsers.

Code:

$(document).ready(function() {
    $('input').on('keydown', function(event) {
        if (this.selectionStart == 0 && event.keyCode >= 65 && event.keyCode <= 90 && !(event.shiftKey) && !(event.ctrlKey) && !(event.metaKey) && !(event.altKey)) {
           var $t = $(this);
           event.preventDefault();
           var char = String.fromCharCode(event.keyCode);
           $t.val(char + $t.val().slice(this.selectionEnd));
           this.setSelectionRange(1,1);
        }
    });
});
