用脚本替换受保护范围内的用户（Google Sheet）

Question

here my specific case:

1. I have some range protected in google sheets
2. I need to replace some specific Editor if is editor of those range (var Editor2Replace and Editor2Add are emails)
3. Logically I tried to, for each sheet:

• Cycle (FOR) of all the protected range (counter p)
• For each protected range catch current editors and have it in array
• Of the Editors read the email ==> this is what generate the mistake
• Cycle (FOR) all the editors looking if someone of those is == Editor2Replace (that is an email)

Here the code, but something is logically wrong, I doubt in what is an array and what not..

   var Protections = sheet.getProtections(SpreadsheetApp.ProtectionType.RANGE);
    for (var p = 0; p < Protections.length; p++) {
      var Protection_Desc = Protections[p].getDescription();
      var Protection_Editors = [];
      var Protection_Editors = [Protections[p].getEditors()];
      for (var r = 0; r < Protection_Editors.length; r++){
         var Protection_Email[r] = [Protection_Editors[r].getEmail()];
         if (Protection_Idontknow == Editor2Replace){
          Protections[p].addEditor = Editor2Add;
          Protections[p].removeEditor = Editor2Replace;

          var Protection_Range = Protections[p].getRange();
          var Protection_Row = Protection_Range.getRow();
          var Owner1 = sheet.getRange(Protection_Row,5).getValue();
          var Owner2 = sheet.getRange(Protection_Row,6).getValue();
          if (Owner1 == Editor2Replace){
              sheet.getRange(Protection_Row,5).setValue(Editor2Add);
          }
          if (Owner2 == Editor2Replace){
              sheet.getRange(Protection_Row,6).setValue(Editor2Add);
          }
        }
      }

Many thanks for hepling

There were a lot of issues in your script and I will enumerate them one by one. Also, I was able to replace a user in the protected sheet by modifying your script.

Issues:

1. Duplicate declaration

var Protection_Editors = [];
var Protection_Editors = [Protections[p].getEditors()];

2. Storing the returned value (array) in another array (which should not be done in your issue, it doesn't help you with anything)

var Protection_Editors = [Protections[p].getEditors()];
...
var Protection_Email[r] = [Protection_Editors[r].getEmail()];

3. Newly declared variable having an index (which I don't understand why)

var Protection_Email[r] = [Protection_Editors[r].getEmail()];

4. Variable not declared Protection_Idontknow

if (Protection_Idontknow == Editor2Replace){

5. Incorrect usage of methods addEditor and removeEditor

Protections[p].addEditor = Editor2Add;
Protections[p].removeEditor = Editor2Replace;

Below code should fix those issues (added some comments):

Code:

  var Protections = sheet.getProtections(SpreadsheetApp.ProtectionType.RANGE);
  for (var p = 0; p < Protections.length; p++) {
    var Protection_Desc = Protections[p].getDescription();
    // returned value of getEditors is already an array, return as is
    var Protection_Editors = Protections[p].getEditors();
    for (var r = 0; r < Protection_Editors.length; r++) {
      var Protection_Email = Protection_Editors[r].getEmail();
      // compare current email with the one you want to replace
      if (Protection_Email == Editor2Replace) {
        // add new and remove the one to replace
        Protections[p].addEditor(Editor2Add);
        Protections[p].removeEditor(Editor2Replace);
      }
    }
  }

Note:

• I have removed anything that were unrelated to the replacement of editors.
