Better way, with solution to tab and chrome problem and new jquery way

$("#element").on("focus keyup", function(e){

        var keycode = e.keyCode ? e.keyCode : e.which ? e.which : e.charCode;
        if(keycode === 9 || !keycode){
            // Hacemos select
            var $this = $(this);
            $this.select();

            // Para Chrome's que da problema
            $this.on("mouseup", function() {
                // Unbindeamos el mouseup
                $this.off("mouseup");
                return false;
            });
        }
    });
