JS simple time comparison method

This article describes the simple method of time comparison of JS. Share it for your reference, as follows:

 //Time comparison (yyyy-MM-dd) function compareDate(startDate, endDate) { var arrStart = startDate.split("-"); var startTime = new Date(arrStart[0], arrStart[1], arrStart[2]); var startTimes = startTime.getTime(); var arrEnd = endDate.split("-"); var endTime = new Date(arrEnd[0], arrEnd[1], arrEnd[2]); var endTimes = endTime.getTime(); if (endTimes<startTimes) { alert("The end time cannot be less than the start time"); return false; } return true;}//Time comparison (yyyy-MM-dd HH:mm:ss) function compareTime(startTime,endTime) { var startTimes = startTime.substring(0, 10).split('-'); var endTimes = endTime.substring(0, 10).split('-'); startTime = startTimes[1] + '-' + startTimes[2] + '-' + startTimes[0] + ' ' + startTime.substring(10, 19); endTime = endTimes[1] + '-' + endTimes[2] + '-' + endTimes[0] + ' ' + endTime.substring(10, 19); var thisResult = (Date.parse(endTime) - Date.parse(startTime)) / 3600 / 1000; if (thisResult < 0) { alert("endTime is less than tartTime!"); } else if (thisResult > 0) { alert("endTime is greater than tartTime!"); } else if (thisResult == 0) { alert("endTime equals tartTime!"); } else { return 'Exception'; }}
