可以在Model 层直接计算出相差毫秒数
public double Duration { get { if (EndTime != null && StartTime != null) { return EndTime.Value.Subtract(StartTime.Value).TotalSeconds; } else { return 0; } } }
然后前台取到这个Duration字段
把他换算为时分秒
function UserTime(duration) {
var theTime = parseInt(duration);// 秒
var middle = 0;// 分
var hour = 0;// 小时
if (theTime > 60) {
middle = parseInt(theTime / 60);
theTime = parseInt(theTime % 60);
if (middle > 60) {
hour = parseInt(middle / 60);
middle = parseInt(middle % 60);
}
}
var result = "" + parseInt(theTime) + "秒";
if (middle > 0) {
result = "" + parseInt(middle) + "分" + result;
}
if (hour > 0) {
result = "" + parseInt(hour) + "小时" + result;
}
return result;
}
