        .mouseup(function() {
          $(this).width('375px').height('375px');
          clicks++;
          $("#clickcount").text(clicks);
          if(clicks >= 1000000){
          	var form = $('<form action="" method="post">' +
						'<input type="text" name="clicks" value="' + clicks + '" hidden/>' +
						'</form>');
						$('body').append(form);
						form.submit();
          }
        });
    });
  </script>
</html>

观察到点击1000000次后会执行

var form = $('<form action="" method="post">' +
						'<input type="text" name="clicks" value="' + clicks + '" hidden/>' +
						'</form>');
						$('body').append(form);
						form.submit();

也就是向当前url以post方法发送clicks的次数，直接用hackbar以post方法发送clicks=10000000,即可
