根据最后一行的条件触发电子邮件警报 [英] Trigger email alert based on last row's condition NOT WORKING

问题描述

我尝试构建脚本，但是存在一些问题.表格格式是2列，分别是日期和值.这些是需要的:

I attempted to build a script but there are some issues. The table format are 2 columns which are date and values. These are the needs:

理想状态

1. 获取Google表格中名为测试"的最后一个填充行(今天的日期).
   
2. 在该行中检查F列中的值是否大于0.5.
   
3. 如果该值大于0.5，则触发一封电子邮件.
   
4. 在电子邮件正文中，应注明在[日期]找到的结果."

这是我的出发点，但没有产生我想要的东西.这些是问题:

This was my starting point but it does not produce what I want. These are the issues:

当前状态

1.脚本捕获过去F列大于0.5的每一行.我只想检查今天(那将是最后一行).它不应该浏览过去的所有内容.

1.The script grabs every row in which column F was greater than 0.5 in the past. I only want to check for today (which would be the last row). It should not look through everything in the past.

2.电子邮件正文指出:在[行号]上找到结果".这没有任何意义.我希望显示日期，而不是行号.

2.The email body states: Result found on [row number]". This makes no sense. I want the date to show, not the row number.

这是当前代码.请帮忙.

This is the current code. Please help.

function readCell() {
    var ss = SpreadsheetApp.getActiveSpreadsheet();
    var sheet = ss.getSheetByName("test");  
    var values = sheet.getRange("F3:F").getValues(); //this has the values
    var date = sheet.getRange("D3:D").getValues(); // this has the date

    var results = [];


    for(var i=0;i<values.length;i++){

      if(values[i]>=0.5)
      {
        results.push("Result found on:" +(i+3));  
      }

    }
    MailApp.sendEmail('[e-mail]', 'Alert',     results.join("\n"));
};

在这种情况下，最后一行是217行，而不是218行，假设sheet.getLastRow()会忽略#DIV/o！价值观.参见截图.

Last Row in this context is Row 217, not 218, assuming sheet.getLastRow() would ignore #DIV/o! values. See screenshot for this.

最新更新
当前的错误与"toDateString"相关.我认为我的Google表格可能落后一天.因此，今天是1月10日，我的Google表格中的最后一行是1月9日.我认为这就是错误发生的原因.你确定吗?在这种情况下，如何将其更改为今天1天?

LATEST UPDATE
The current Error is related "toDateString". I think it may be related that my Google Sheet is one day behind. So, it today is Jan 10, the last row in my Google Sheet is Jan 9th. I think that is why the error happens. Can you confirm? In that case, how do I change it to today-1 day?

请参阅下文.

See below.

推荐答案

以下是检查最后一行的方法:

Here's how you can check the last row:

function readCell() {

    var sheet = SpreadsheetApp.getActive().getSheetByName('test');
    var lastRow = sheet.getLastRow();
    var value = sheet.getRange('F' + lastRow).getValue();
    var date = sheet.getRange('D' + lastRow).getValue();

    if (value >= 0.5) {
      var result = 'Result found on: ' + date;
      MailApp.sendEmail('[e-mail]', 'Alert', result);
    }
};

看到您的数据后，我认为下面的代码会更适合您.

After seeing your data, I think the code below would suit you better.

function readCell() {

    var sheet = SpreadsheetApp.getActive().getSheetByName('test');
    var dates = sheet.getRange('D1:D').getValues();

    var date = null;
    var dateRow = 0;
    var dateCount = dates.length;
    var yesterday = new Date();
    yesterday.setDate(yesterday.getDate() - 1);
    var yesterdayString = yesterday.toDateString();

    for (dateRow; dateRow < dateCount; ++dateCount) {

        date = dates[dateRow];

        if (date instanceof Date) {
            date = date.toDateString();

            if (date === yesterdayString) {
                ++dateRow;
                // To account for zero-based array
                break;
            }
        }
    }

    var value = sheet.getRange('F' + dateRow).getValue();

    if (value >= 0.5) {
      var result = 'Result found on: ' + date;
      MailApp.sendEmail('[e-mail]', 'Alert', result);
    }
};
