当单元格为特定颜色时触发电子邮件吗? [英] Trigger an email when a cell is a certain colour?

问题描述

对此我的知识非常有限.太少了，我什至都不应该将其称为知识"

I have very VERY limited knowledge on this. So little I probably shouldn't even refer to it as "knowledge"

这就是我想要做的: 我有一列提到发送日期的日期.如果日期已经过去，则该单元格将变为红色(#a33838).如果该列中的单元格变成红色，我想发送一封电子邮件，以便我知道它尚未发送，需要处理. 我还希望电子邮件保存该单元格所在行的信息

This is what I'm trying to do: I have a column with dates referring to send dates. If the date has already passed, the cell turns red (#a33838). I want to send an email if a cell in that column turns red, so that I know it has not been sent, and needs doing. I also want the email to hold the information of the row that cell is in

我一直在浏览论坛，我认为我需要混合使用这两种不同的帖子:

I have been looking through the forums and I think I need a mixture of these two different posts:

根据google中的单元格颜色更改单元格值电子表格

在单元格具有某些值时触发电子邮件 a>

如果有人知道这样做的方法，那将真的是一个救命稻草！ 非常感谢.

If anyone knows a way to do this, it would really be a lifesaver! Thanks so much.

推荐答案

此代码将为您提供所需的帮助

This code will help you in what you need

var EMAIL_ADDRESS = "email@domain";
var SUBJECT = "Passed dates";
var message = "";

function alertDate() {
  var sheet = SpreadsheetApp.getActiveSpreadsheet().getActiveSheet(); // get the sheet where values are
  var date_col = sheet.getRange(1, 1, sheet.getLastRow()); // get the column with the dates
  var dates = date_col.getValues();
  var row = 0;
  for(var i = 0; i < dates.length; i++){ // iterate over all dates 
    if( dates[i] < Utilities.formatDate(new Date(), "GMT", "MM/dd/yyyy")){ // check if date already passed
      date_col.getCell(i + 1, 1).setBackground("#A33838"); // change cell´s color
      row = i + 1;
      message += "This date " + dates[i] + " on row " + row.toString() + " has already passed\n"; // build message to send
    }
  }
  MailApp.sendEmail(EMAIL_ADDRESS, SUBJECT, message); // send email
}

注意:

我在示例中使用的日期格式为 "MM/dd/yyyy" ，因此，如果您在工作表中使用其他格式，则需要改变这个:

Notice:

I´m using the format "MM/dd/yyyy" for the dates in my example, so if you use another format in your sheet, you need to change this:

Utilities.formatDate(new Date(), "GMT", "MM/dd/yyyy")
