如何在Google表格脚本中比较时间？

Question

In google sheets, I am looping through a range of cells, then splitting the part of the string that contains a time. Example: 6:40 AM is derived from TEST:6:40 AM using the line:

text.slice(text.indexOf(":") + 1, text.length);

I am then trying to see if this time matches the time of the cell next to the cell that originally called the function.

var sheetTime = timeSheetRange.getCell(1,1).getValue();
var time = 0;
  for (var i = 1; i <= 30; i++) {
      for (var j = 1; j <= 8; j++) {
          time = getTime(taskRange.getCell(i,j).getValue());
          if (time == sheetTime) {
              return time;
          }
          else {
              return "NO ACTIVITY";
          }
      }
  }

The problem is that when putting in the same time values for time and sheeetTime , time does not equal sheetTime .

Returning both time and sheetTime prints out the correct, equal times. I have a feeling that it might have to do with the cell time formatting? time is reading from this cell:

While sheetTime is reading from this cell:

SO what's going on here? Is it the formatting that I have to chage or am I approaching this wrong? Thanks.

The issue is that sheetTime is an actual time value. Ideally, you'd be comparing time with time, but the easiest way is to use getDisplayValue() (as suggested by Serge insas in a comment to my original answer).

var sheetTime = timeSheetRange.getCell(1,1).getDisplayValue();

As an overall suggestion, try using Logger.log() statements to try debugging. You'll be able to see exactly what values your script is working with.
