看来您打错了字：
var LastTenMin= new Date(NowDate.getFullYear(), NowDate.getMonth(), NowDate.getDate(),NowDate.getHours(),NowDate.getMinutes(),- 10);
应该是（请注意逗号）：
var LastTenMin= new Date(NowDate.getFullYear(), NowDate.getMonth(), NowDate.getDate(),NowDate.getHours(),NowDate.getMinutes() - 10);
另外，您试图从日期对象创建新的日期对象，这是不正确的：
new Date(LastTenMin)
var NowDate= new Date();
var Time1 = new Date("04/12/2013 01:03:00");
var LastTenMin= new Date(NowDate.getFullYear(), NowDate.getMonth(), NowDate.getDate(), NowDate.getHours(), NowDate.getMinutes() - 10);
// Should return true
console.log(Time1 < LastTenMin);
// Change the year to a point in the future
Time1 = new Date("04/12/2014 01:03:00");
// Shold return false
console.log(Time1 < LastTenMin);
// So your original conditional should look like this:
if (Time1 < LastTenMin) {
image2 = '/Images/truckOnline.png';
status = "Truck is online."+"\n"+"Last seen:"+" "+Time1;
} else {
image2 = '/Images/truckOffline.png';
status = "Truck is offline"+"\n"+"Last seen:"+" "+Time1;
}
// And a more concise form:
var isOnline = !(Time1 < LastTenMin);
var image2 = isOnline ? '/Images/truckOnline.png' : '/Images/truckOffline.png';
var status = "Truck is " + (isOnline ? "Online" : "Offline") + "." + "\n" + "Last seen:" + " " + Time1
这是不加注释的解决方案：
var NowDate= new Date();
var Time1 = new Date(data2.LastRecordTime);
var LastTenMin= new Date(NowDate.getFullYear(), NowDate.getMonth(), NowDate.getDate(), NowDate.getHours(), NowDate.getMinutes() - 10);
var isOnline = !(Time1 < LastTenMin);
var image2 = isOnline ? '/Images/truckOnline.png' : '/Images/truckOffline.png';
var status = "Truck is " + (isOnline ? "Online" : "Offline") + "." + "\n" + "Last seen:" + " " + Time1
我的整个解决方案都假设data2.LastRecordTime中包含的字符串的格式为：“ MM.DD.YYYY HH：MM：SS”。
