JS常用的方法

1.时间戳转换

//时间戳(有Date和无Date的都可)转换为日期 “2016年5月30日 10:29:30   2016-05-20 09:11”
function TimeConversion(timeStamp,type) {
    if (timeStamp) {
        if (timeStamp.indexOf('Date') > -1) {
            var dtime = timeStamp.substring(6, timeStamp.length - 2);
            var newDate = new Date();
            newDate.setTime(dtime);
            var year = newDate.getFullYear();
            var month = newDate.getMonth() + 1;
            var data = newDate.getDate();
            var hour = '0' + newDate.getHours();
            hour = hour.substring(hour.length - 2)
            var minute = '0' + newDate.getMinutes();
            minute = minute.substring(minute.length - 2)
            var second = '0' + newDate.getSeconds();
            second = second.substring(second.length - 2)
            var s = "";
            if (type && type == 1) {
                s = year + "-" + month + "-" + data + "  " + hour + ":" + minute;
            }
            else {
                s = year + "年" + month + "月" + data + "日  " + hour + ":" + minute + ":" + second;
            }

            return s;
        }
        else {
            var dt = timeStamp.split(' ');
            var s = dt;
            if (dt.length > 1) {
                var date = dt[0].split('/');
                var time = dt[1].split(':');
                var hour = '0' + time[0];
                hour = hour.substring(hour.length - 2);
                if (type && type == 1) {
                    s = date[0] + "-" + date[1] + "-" + date[2] + "  " + hour + ":" + time[1];
                }
                else {
                    s = date[0] + "年" + date[1] + "月" + date[2] + "日  " + hour + ":" + time[1] + ":" + time[2];
                }
            }
            return s;
        }
    }
