addClass

验证码倒计时

    //验证码函数
    function time(btnObj) {
        if (wait == 0) {
            $(btnObj).removeClass('long-text get-code-disable').addClass('get-code').text('获取验证码');
            wait = 60;
        } else {
            $(btnObj).removeClass('get-code').addClass('long-text get-code-disable').text( wait + "s后重新获取");
            wait--;
            setTimeout(function() {
                time(btnObj)
            },1000)
        }
    }    //验证
