Question

我下面有我的代码，

    Before=document.getElementsByName("beforehr[]");
    After=document.getElementsByName("afterhr[]");
    MonthTotal=0
    for(i=0;i<Before.length;i++){
        BeforeInSeconds= // Convert Before[i].value to Seconds
        AfterInSeconds= // Convert After[i].value to Seconds
        MonthTotal=parseInt(MonthTotal)+ parseInt(BeforeInSeconds)+parseInt(AfterInSeconds);

}
MonthTotalHRS= // Convert MonthTotal value to Time
document.getElementById("txtMonthTotal").value=MonthTotal;
document.getElementById("Mthtotal").innerHTML=MonthTotalHRS;

我需要将“小时前”转换为秒，将“小时后”转换为秒，将所有秒数相加并转换为时间，然后将其放入Mthtotal

Answer 1

假定变量Before和After是数组。

var Before = [1, 2]; //180 Secs
var After = [3, 4]; // 420 Secs
var MonthTotal=0;

function secondsToHms(d) {  // Function to convert Secs to H:m:s
    d = Number(d);
    var h = Math.floor(d / 3600);
    var m = Math.floor(d % 3600 / 60);
    var s = Math.floor(d % 3600 % 60);

    var hDisplay = h > 0 ? h + (h == 1 ? " hour " : " hours ") : "";
    var mDisplay = m > 0 ? m + (m == 1 ? " minute " : " minutes ") : "";
    var sDisplay = s > 0 ? s + (s == 1 ? " second" : " seconds") : "";
    return hDisplay + mDisplay + sDisplay; 
}

for(i=0;i<Before.length;i++)
{
	BeforeInSeconds= Before[i] * 60;
	AfterInSeconds= After[i] * 60;
	MonthTotal=parseInt(MonthTotal)+ parseInt(BeforeInSeconds)+parseInt(AfterInSeconds);
}
console.log(MonthTotal); //600 Secs

var convertedop=secondsToHms(MonthTotal);
alert(convertedop);

您可以使用.split(':')将时间格式分成一个数组。其中索引0是小时，索引1是分钟，索引2是秒。然后，您可以将每个时间单位转换为秒。

小时到秒：hour*3600

分钟至秒：minutes*60

秒到秒：seconds*1就是seconds

完成所有这些操作将为您提供总的结果：

var before = [...document.getElementsByName("beforehr[]")];
var after = [...document.getElementsByName("afterhr[]")];

var monthTotal = 0
for (i = 0; i < before.length; i++) {
  var beforeTime = before[i].value.split(':');
  var afterTime = after[i].value.split(':');
  
  var hourSeconds = +beforeTime[0] * 3600; // Convert the hours to seconds
  var minuteSeconds = +beforeTime[1] * 60; // Convert the mins to secs
  var seconds = +beforeTime[2]; // No conversions needed for secs to secs
 
  var beforeInSeconds = hourSeconds + minuteSeconds + seconds;
  
  // The above can be compresed into one line. I'll repeat the above for the afterTime on one line as an example:
  var afterInSeconds = (+afterTime[0] * 3600) + (+afterTime[1] * 60) + (+afterTime[2])
  monthTotal += parseInt(beforeInSeconds) + parseInt(afterInSeconds);
}

console.log("Month total in seconds", monthTotal)

// Hours, minutes and seconds (round down)
var hrs = ~~(monthTotal / 3600);
var mins = ~~((monthTotal % 3600) / 60);
var secs = ~~monthTotal % 60;

console.log("Month total in H:M:S", hrs +':' +mins + ':' + secs);

<input type="text" value="1:0:0" name="beforehr[]" />
<input type="text" value="1:0:0" name="beforehr[]" />

<br />

<input type="text" value="4:0:0" name="afterhr[]" />
<input type="text" value="4:0:0" name="afterhr[]" />

此外，请注意，一元+运算符与parseInt类似（但是其作用略有不同）。

简化的解决方案

void VideosInsertRequest_ProgressChanged(Google.Apis.Upload.IUploadProgress progress)
{
    switch (progress.Status)
    {
        case UploadStatus.Uploading:
            UpdateStatus(String.Format("{0} bytes sent.", progress.BytesSent));
            break;

        case UploadStatus.Failed:
            UpdateStatus(String.Format("An error prevented the upload from completing.{0}", progress.Exception));
            break;
    }
}

void VideosInsertRequest_ResponseReceived(Video video)
{
    UpdateStatus(string.Format("Video id '{0}' was successfully uploaded.", video.Id));
}

private void UpdateStatus(string status)
{
    StatusLabel.Dispatcher.BeginInvoke(new Action(() => { StatusLabel.Content = status; }));
}
