核心代碼
/* * 獲得時(shí)間差,時(shí)間格式為 年-月-日 小時(shí):分鐘:秒 或者 年/月/日 小時(shí)：分鐘：秒 * 其中，年月日為全格式，例如 ： 2010-10-12 01:00:00 * 返回精度為：秒，分，小時(shí)，天 */ function GetDateDiff(startTime, endTime, diffType) { //將xxxx-xx-xx的時(shí)間格式，轉(zhuǎn)換為 xxxx/xx/xx的格式 startTime = startTime.replace(//-/g, "/"); endTime = endTime.replace(//-/g, "/"); //將計(jì)算間隔類性字符轉(zhuǎn)換為小寫 diffType = diffType.toLowerCase(); var sTime = new Date(startTime); //開始時(shí)間 var eTime = new Date(endTime); //結(jié)束時(shí)間 //作為除數(shù)的數(shù)字 var divNum = 1; switch (diffType) { case "second": divNum = 1000; break; case "minute": divNum = 1000 * 60; break; case "hour": divNum = 1000 * 3600; break; case "day": divNum = 1000 * 3600 * 24; break; default: break; } return parseInt((eTime.getTime() - sTime.getTime()) / parseInt(divNum)); } 調(diào)用方法也很簡單：
GetDateDiff("2010-10-11 00:00:00", "2010-10-11 00:01:40", "day")
這個(gè)是計(jì)算天數(shù)
GetDateDiff("2010-10-11 00:00:00", "2010-10-11 00:01:40", "seond")是計(jì)算秒數(shù)
下面武林網(wǎng)小編再為大家分析一個(gè)不錯(cuò)的
