查找给定标题行名称的列 [英] Find column given name of title row

问题描述

给出一些表格:

通过在:

I'm able to get the B-column's first row value datetime by hardcoding column index in A1 notation, "B:B", into my onEdit function:

function onEdit(event)
{
  var datetime_col = "B:B";
  Logger.log(event.range.getSheet().getRange(datetime_col).getValue());
  //=> [17-03-06 11:39:47:752 PST] datetime
}

但是我想要给定列ID "datetime"的列ID.

But I want the column id given the string "datetime".

对我而言，列是否表示为范围，字符串"B:B"，字符串"B"或其他标识符对我来说都没有关系.重要的一点是我想查找具有该名称的列，而不是相反.

It doesn't matter to me if the column is represented as a range, the string "B:B", the string "B", or some other identifier. The important bit is I want to find the column given the name not the other way around.

• 这可能吗?
• 您是否可以在类表中找到该函数文档?

推荐答案

将数据的第一行移至最后一列，然后使用indexOf(col_Title)

Get the first row of data to the last column, then use indexOf(col_Title)

function onEdit(event) {
  var columnNeeded,data,lastColumn,sh;

  sh = SpreadsheetApp.getActiveSheet();
  lastColumn = sh.getLastColumn();

  data = sh.getRange(1,1,1,lastColumn).getValues();//Get 2D array of all values in row one
  data = data[0];//Get the first and only inner array

  columnNeeded = data.indexOf('datetime') + 1;//Arrays are zero indexed- add 1

  Logger.log('columnNeeded: ' + columnNeeded);

}
