如何使用 Utilities.sleep() 函数 [英] How to use Utilities.sleep() function

问题描述

Utilities.sleep() 函数的确切用途是什么?我们应该在函数调用或 API 调用之间使用它吗?

What is the exact use of Utilities.sleep() function? Should we use it between function calls or API calls?

我在函数调用之间使用了 Utilities.sleep(1000)，对吗?它会减慢执行时间吗?

I use the Utilities.sleep(1000) in-between function calls, is it right? Will it slow down the execution time?

推荐答案

Utilities.sleep(milliseconds) 在程序执行中创建一个暂停"，这意味着它在您要求的毫秒数内不执行任何操作.它肯定会减慢你的整个过程，你不应该在函数调用之间使用它.不过也有一些例外，至少我知道的是:在 SpreadsheetApp 中，当您想要删除多个工作表时，您可以在每次删除之间添加数百毫秒以允许正常的脚本执行(但这是一种解决方法)此特定方法的一个已知问题).在电子表格中创建许多工作表时，我也必须使用它，以避免浏览器在执行后需要刷新".

Utilities.sleep(milliseconds) creates a 'pause' in program execution, meaning it does nothing during the number of milliseconds you ask. It surely slows down your whole process and you shouldn't use it between function calls. There are a few exceptions though, at least that one that I know : in SpreadsheetApp when you want to remove a number of sheets you can add a few hundreds of millisecs between each deletion to allow for normal script execution (but this is a workaround for a known issue with this specific method). I did have to use it also when creating many sheets in a spreadsheet to avoid the Browser needing to be 'refreshed' after execution.

这是一个例子:

function delsheets(){
  var ss = SpreadsheetApp.getActiveSpreadsheet();
  var numbofsheet=ss.getNumSheets();// check how many sheets in the spreadsheet
  for (pa=numbofsheet-1;pa>0;--pa){ 
    ss.setActiveSheet(ss.getSheets()[pa]);
    var newSheet = ss.deleteActiveSheet(); // delete sheets begining with the last one
    Utilities.sleep(200);// pause in the loop for 200 milliseconds
  }
  ss.setActiveSheet(ss.getSheets()[0]);// return to first sheet as active sheet (useful in 'list' function)
}
