使用onEdit触发器将值返回到Google电子表格中的单元格

Question

I'm basically trying to make a script that when cell C4 is changed or edited then it will return the variable "date" to cell L4 .

 function onEdit(e) {
  var sheet = SpreadsheetApp.getActiveSpreadsheet();
  var date = Utilities.formatDate(new Date(), "GMT+1", "yyyy/MM/dd");
  var cellAddress = e.range.getA1Notation();

  if ( CellAdress === 'C4' ) {
    var range = sheet.getActiveSheet().getRange('L4');
    var nrange = sheet.setActiveRange(range);
    nrange = date
  }
}

I know that the last part doesn't work, but I can't get my head around how to properly use the functions, been searching for a while but can't find anything related precisely to making the function change the cell.

Answer 1

Write new Date() string to L4 when C4 is edited on any Sheet

Please note this function is called whenever any edit is made on any sheet. Since this function does not specify a sheet, then an edit of cell C4 on any sheet will set the value of L4 on on that sheet. So I would recommend that you add some sheet restrictions as shown in the comments.

function onEdit(e) {
  var rg=e.range;
  var sh=rg.getsheet();
  var row=rg.getRow();
  var col=rg.getColumn();
  if(col==3 && row==4){//Page Restrictions Added: if(sh.getName()=='sheetname' && col==3 && row==4){
    sh.getRange(4,12).setValue(Utilities.formatDate(new Date(), "GMT+1", "yyyy/MM/dd"));
  }
}

• Get Range
• RangeGetSheet

Answer 2

I saw your answer (Write new Date() string to L4 when C4 is edited on any Sheet). I try with my programm, but it doesn't work. My programm is the following :

function onedit(e) {
    var valeur_1=1;
    var rg=e.range;
    var sh=rg.getsheet();
    var row=rg.getRow();
    var col= rg.getColumn();
    if(col==1 && row==1) {
        sh.getRange(2,1).setValue(valeur_1);
} 

I wanted try with a simple programm, If I understand well, if the value in A1 change then I will obtain the value Valeur_1 in cell A2, it is all right ot not??
