此代码通过使用现有唯一值(如果存在)覆盖现有行来防止在提交 Google 表单时在 Google 表格中出现重复。该代码在电子表格中搜索一列并查找匹配项。我试图使其通用,以便不需要根据唯一标识符所在的列更改代码。您需要在“用户设置”部分进行一些设置以使其工作。但这比需要重写代码要好。
function updateExisting(columnWithUniqueIdentifier,sheetTabName) {
var dataFromColumnToMatch,lastColumn,lastRow,rowWithExistingUniqueValue,rowOfDataJustSaved,
sh,ss,valueToSearchFor;
// USER SETTINGS - if the values where not passed in to the function
if (!columnWithUniqueIdentifier) {//If you are not passing in the column number
columnWithUniqueIdentifier = 2;//Hard code column number if you want
}
if (!sheetTabName) {//The sheet tab name was not passed in to the function
sheetTabName = "Put your Sheet tab name here";//Hard code if needed

sh = ss.getSheetByName(sheetTabName);
lastRow = sh.getLastRow();

rowOfDataJustSaved = sh.getRange(lastRow, 1, 1, lastColumn).getValues();//Get the values that were just saved
