javascript - get a number inside a div and count plus one

Question

I am using the code below to get the value(number) inside a div and plus one but if the value is 1 and I am pressing my button it gives me 01 and I want to plus one and if it is 2 and press my button again it gives me 22.

My code is:

<div class="mybtn">0</div>

<script>

$(function() {

$(".buttonDown").click(function() 
{
var checkDown = $('.buttonDown').text();
$('.mybtn').hide("fast");
$('.mybtn').text(checkDown+1);
$('.mybtn').fadeIn("slow");
});

});
</script>

Answer 1

$(function () {
    $(".mybtn").click(function () {
        var $this = $(this).stop(true, true).hide("fast");
        var checkDown = parseInt($.trim($(this).text()), 10);
        $this.text(checkDown + 1).fadeIn("slow");
    });
});
