基本上，此脚本将从 EndTime 中减去 StartTime，使用 jQuery 插件在 html 表单中填充 HH:MM 格式的开始和结束时间，输入字段填充结果，除了一个问题外，它可以工作：
如果开始时间在 08:00 到 09:59 之间，它只会返回奇怪的结果 - 准确地说，结果是 10 小时，为什么？
所有其他输入都正确计算！
function setValue() {
var startTime = document.getElementById('ToilA');
var endTime = document.getElementById('EndHours'); startTime = startTime.value.split(":");
var startHour = parseInt(startTime[0]);
var startMinutes = parseInt(startTime[1]);
endTime = endTime.value.split(":");
var endHour = parseInt(endTime[0]);
var endMinutes = parseInt(endTime[1]);
//var hours, minutes;
var today = new Date();
var time1 = new Date(2000, 01, 01, startHour, startMinutes, 0);
var time2 = new Date(2000, 01, 01, endHour, endMinutes, 0); var milliSecs = (time2 - time1);
msSecs = (1000);
msMins = (msSecs * 60);
msHours = (msMins * 60);
numHours = Math.floor(milliSecs/msHours);
numMins = Math.floor((milliSecs - (numHours * msHours)) / msMins);
numSecs = Math.floor((milliSecs - (numHours * msHours) - (numMins * msMins))/ msSecs); numSecs = "0" + numSecs; numMins = "0" + numMins; DateCalc = (numHours + ":" + numMins);
document.getElementById('CalculateHours').value = DateCalc; }
