日期搜索自动报告 - Google文档(Date Search for Automatic Reporting - Google Docs)

好的,我在问这个之前已经经过这个站点前进和后退,但由于某种原因我无法获得我已经实现的代码自动工作。 我只需要运行脚本(我已经设置了一个触发器)来检查表5第3列(称为Reports)中的电子邮件。 如果今天的日期与给定的日期相符,我需要它向我发送包含第1列数据和第2列数据的电子邮件。

有人可以查看代码并给我一些帮助吗?

function sendEmails() {
  var spreadsheet = SpreadsheetApp.openById('Unique ID for spreadsheet');           

  var sheet = spreadsheet.getSheets()[4];

  var startRow = 2;  // First row of data to process
  var numRows = 250;   // Number of rows to process
  // Fetch the range of cells
  var dataRange = sheet.getRange(startRow, 1, numRows, 4)
  // Fetch values for each row in the Range.
  var data = dataRange.getValues();   

  var emailAddress = 'email@email.com';
  var subject = "Report Today";

  for (i in data) {
    var row = data[i];
    if( row[3] == true) {
      var message = row[0]+row[1];
      try {
          MailApp.sendEmail(emailAddress, subject, message);
      } catch(errorDetails) {
        MailApp.sendEmail("Email@email.com", "sendEmail script error", errorDetails.message);
      }

    }
  }
}

Ok I've been through this site forward and backward before asking this but for some reason I can't get the code I've implemented to work automatically. I just need the script to run (I setup a trigger already) to check the email in column 3 of sheet 5 (called Reports). I need it to send me an email with column 1 data and column 2 data if today's date matches the date given.

Can someone look at the code and give me a little help?

function sendEmails() {
  var spreadsheet = SpreadsheetApp.openById('Unique ID for spreadsheet');           

  var sheet = spreadsheet.getSheets()[4];

  var startRow = 2;  // First row of data to process
  var numRows = 250;   // Number of rows to process
  // Fetch the range of cells
  var dataRange = sheet.getRange(startRow, 1, numRows, 4)
  // Fetch values for each row in the Range.
  var data = dataRange.getValues();   

  var emailAddress = 'email@email.com';
  var subject = "Report Today";

  for (i in data) {
    var row = data[i];
    if( row[3] == true) {
      var message = row[0]+row[1];
      try {
          MailApp.sendEmail(emailAddress, subject, message);
      } catch(errorDetails) {
        MailApp.sendEmail("Email@email.com", "sendEmail script error", errorDetails.message);
      }

    }
  }
}

最满意答案

这是可选的展开。
正如你注意到的那样 - 开发者可以将函数的结果转换为MKMarkerAnnotationView 。 但是, if let语法是可选的解包,他也会使用它。 这意味着这个代码

dequeuedView.annotation = annotation
view = dequeuedView

只会在投射成功时执行(即投射结果不nil )。 否则这段代码将被忽略。

你也可以用guard语句来做到这一点。 例如:

guard let dequeuedView = mapView.dequeueReusableAnnotationView(withIdentifier: identifier) as? MKMarkerAnnotationView 
else { // code here will be executed if casting fails. In this case you also have to return function }

dequeuedView.annotation = annotation
view = dequeuedView

This is optional unwrapping.
As you noticed - developer optionally casted function's result to MKMarkerAnnotationView. But he also used this with if let syntax which is optional unwrapping. This means that this code

dequeuedView.annotation = annotation
view = dequeuedView

will only be executed if cast succeeded (i.e. if cast result wasn't nil). Otherwise this code will be ignored.

You can also do this with guard statement. E.g.:

guard let dequeuedView = mapView.dequeueReusableAnnotationView(withIdentifier: identifier) as? MKMarkerAnnotationView 
else { // code here will be executed if casting fails. In this case you also have to return function }

dequeuedView.annotation = annotation
view = dequeuedView
