JS calculate date time difference-JS Tutorial-php.cn

This time I will bring you JS to calculate the date and time difference. What are theprecautions for JS to calculate the date and time difference? The following is a practical case, let's take a look.

The code for js to determine date and time is as follows:

alert(GetDateDiff("2018-02-27 19:20:22","2018-02-27 09:20:22","hour")); function GetDateDiff(startTime, endTime, diffType) { //将xxxx-xx-xx的时间格式，转换为 xxxx/xx/xx的格式 startTime = startTime.replace(/\-/g, "/"); endTime = endTime.replace(/\-/g, "/"); //将计算间隔类性字符转换为小写 diffType = diffType.toLowerCase(); var sTime =new Date(startTime); //开始时间 var eTime =new Date(endTime); //结束时间 //作为除数的数字 var timeType =1; switch (diffType) { case"second": timeType =1000; break; case"minute": timeType =1000*60; break; case"hour": timeType =1000*3600; break; case"day": timeType =1000*3600*24; break; default: break; } return parseInt((eTime.getTime() - sTime.getTime()) / parseInt(timeType)); }

PS: Let’s look at js to find the time difference

var date1=new Date(); //开始时间 alert("aa"); var date2=new Date(); //结束时间 var date3=date2.getTime()-date1.getTime() //时间差的毫秒数 //计算出相差天数 var days=Math.floor(date3/(24*3600*1000)) //计算出小时数 var leave1=date3%(24*3600*1000) //计算天数后剩余的毫秒数 var hours=Math.floor(leave1/(3600*1000)) //计算相差分钟数 var leave2=leave1%(3600*1000) //计算小时数后剩余的毫秒数 var minutes=Math.floor(leave2/(60*1000)) //计算相差秒数 var leave3=leave2%(60*1000) //计算分钟数后剩余的毫秒数 var seconds=Math.round(leave3/1000) alert(" 相差 "+days+"天 "+hours+"小时 "+minutes+" 分钟"+seconds+" 秒")
