格式化时间

    var date = new Date();
    var y = date.getFullYear();
    var m = date.getMonth() + 1;
    // m = m < 10 ? '0' + m : m;
    var d = date.getDate();
    // d = d < 10 ? '0' + d : d;
    var h = date.getHours();
    // h = h < 10 ? '0' + h : h;
    var minute = date.getMinutes();
    var second = date.getSeconds();
    // minute = minute < 10 ? '0' + minute : minute;
    // second = second < 10 ? '0' + second : second;
    return y + '-' + m + '-' + d + ' ' + h + ':' + minute + ':' + second;
  },

将标准时间转成unix时间

    var str = dateTime;
    str = str.replace(/-/g, '/');
    var date = new Date(str);
    var humanDate = new Date(
      Date.UTC(
        date.getFullYear(),
        date.getMonth(),
        date.getDate(),
        date.getHours(),
        date.getMinutes(),
        date.getSeconds()
      )
    );
    return humanDate.getTime() / 1000 - 8 * 60 * 60;
  },

比较两个时间相差天数

datedifference:function(sDate1, sDate2) {//sDate1和sDate2是2006-12-18格
        var that=this;
        var dateSpan,
            tempDate,
            iDays;
        sDate1 = Date.parse(sDate1);
        sDate2 = Date.parse(sDate2);
        dateSpan = sDate2 - sDate1;
        dateSpan = Math.abs(dateSpan);
        iDays = Math.floor(dateSpan / (24 * 3600 * 1000));
        return iDays
    },
