当我在单元格 A 中输入值时如何在谷歌工作表中自动填充日期

Question

如果我在工作表的单元格 A 中输入“已付款”文本，我想在单元格 B 中自动提取当前日期。如果单元格为空，则不应提取日期。喜欢：

--------------------------------------
A           |  B
--------------------------------------
Paid        |  2/25/2018
----------------------------------
Paid        | 2/26/2018 
----------------------------------
empty cell  |   
----------------------------------
empty cell  |  




I tried to use =ArrayFormula(IF(A2:A81=paid),"paid",(NOW())) 

但得到错误。他们有什么办法吗？

Answer 1

尝试这个：

=ArrayFormula(IF(A2:A81="paid", NOW(),"")) 

如果您永远不想更改日期，则需要使用如下脚本：

function onEdit() {
  // writes the current date to the cell to the right on the row when a cell in a specific column is edited
  // adjust the following variables to fit your needs

  var sheetNameToWatch = "Sheet1";
  var columnNumberToWatch = /* column A */ 1; // column A = 1, B = 2, etc.
  var valueToWatch="paid";

  var ss = SpreadsheetApp.getActiveSpreadsheet();
  var sheet = SpreadsheetApp.getActiveSheet();
  var range = sheet.getActiveCell();
  var val=sheet.getActiveCell().getValue()

  if (sheet.getName() == sheetNameToWatch && range.getColumn() == columnNumberToWatch && val==valueToWatch) {
    var targetCell = sheet.getRange(range.getRow(), range.getColumn()+1
                               );
    targetCell.setValue("" + Utilities.formatDate(new Date(), "GMT", "MM/dd/yyyy"));
  }
}

没有办法用我知道的公式来做到这一点。它可以更短，但仍然需要脚本：

function onEdit(e) {
   if (e.source.getSheetName()=="Sheet1" && e.range.getColumn() == 1 && e.range.getValue() == "paid") {
      e.range.offset(0,1).setValue(new Date());
  }}
