btn1 = $('.js-wait-audit');btn2 = $('.js-wait-publish');btn3 = $('.js-running');btn4 = $('.js-pause');btn5 = $('.js-overdue');btn6 = $('.js-text');div1 = $('.wait-audit');div2 = $('.wait-publish');div3 = $('.running');div4 = $('.pause');div5 = $('.overdue');div6 = $('.text');如何把btn2-6編為一組，div2-6編為一組，達到如下例子：btn1.click(function(){    btn1.addClass('current');    div1.addClass('open');    exceptBtn1.removeClass('current');    exceptDiv1.removeClass('open');});
