Google工作表脚本可将工作表中的日期添加一周

Question

Sorry - I'm a newbie!

I need to use a script to read a date from a Googlesheet, add a week and save the new date back to the sheet.

I've tried various suggestions from various posts without success. The approach I thought should work is failing to get a millisecond value from a date from a cell - subsequent processing appeared OK.

var oldDate  = sheet.getRange('oldDateRange').getValue(); // obtains a date object and then...
var oldDateValue = oldDate.getMilliseconds() // I expected to return milliseconds but shows as undefined...

See link to a simplified illustration sheet and script illustrating my problem.

This is my first question on StackOverflow - feedback welcome on how to make it more helpful for others....

为了将从工作表中获得的日期转换为毫秒，我认为您只需要将.getMilliseconds()替换为.getTime()
