js Simple Time Comparison Method

In this paper, an example is given to describe the method of simple 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(" End time cannot be less than 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 Less than tartTime ! ");
  } else if (thisResult > 0) {
    alert("endTime Greater than tartTime ! ");
  } else if (thisResult == 0) {
    alert("endTime Equal to tartTime ! ");
  } else {
    return ' Anomaly ';
  }
}
