JS计算两个日期时间差，天 小时 分 秒格式
function getDateDiff(dateTimeStamp) {var minute = 1000 * 60;var hour = minute * 60;var day = hour * 24;var halfamonth = day * 15;var month = day * 30;var now = new Date().getTime();var diffValue = now - dateTimeStamp;if (diffValue < 0) { return; }var monthC: any = diffValue / month;var weekC: any = diffValue / (7 * day);var dayC: any = diffValue / day;var hourC: any = diffValue / hour;var minC: any = diffValue / minute;var result;if (monthC >= 1) {result = "" + parseInt(monthC) + "月前";} else if (weekC >= 1) {result = "" + parseInt(weekC) + "周前";} else if (dayC >= 1) {result = "" + parseInt(dayC) + "天前";} else if (hourC >= 1) {result = "" + parseInt(hourC) + "小时前";} else if (minC >= 1) {result = "" + parseInt(minC) + "分钟前";} else {result = "刚刚";}return result;}
