Question

表：支持
列：H具有以下功能＆＃34; = IF（D：D> 0; IF（$ B $ 1＆gt; = $ G：G;＆＃34; Call＆＃34 ;;＆＃34; In时间＆＃34;）;＆＃34;＆＃34;）＆＃34; 根据结果更改值。

问题：

我需要：

当H列中的单元格变为＆＃34; Call＆＃34;在表格上＆＃34;支持＆＃34;。

此功能需要每隔5分钟运行一次。


是否需要将声音上传到云端硬盘，还是可以使用来自网址的声音？

我很感激任何人都可以提供帮助...我看到很多代码，但我不太了解。

这是一个非常棘手的问题，但可以使用侧边栏来定期轮询H列以进行更改。

<强> Code.gs

// creates a custom menu when the spreadsheet is opened
function onOpen() {
  var ui = SpreadsheetApp.getUi()
    .createMenu('Call App')
    .addItem('Open Call Notifier', 'openCallNotifier')
    .addToUi();

  // you could also open the call notifier sidebar when the spreadsheet opens
  // if you find that more convenient
  // openCallNotifier();
}

// opens the sidebar app
function openCallNotifier() {
  // get the html from the file called "Page.html"
  var html = HtmlService.createHtmlOutputFromFile('Page') 
    .setTitle("Call Notifier");

  // open the sidebar
  SpreadsheetApp.getUi()
    .showSidebar(html);
}

// returns a list of values in column H
function getColumnH() {
  var sheet = SpreadsheetApp.getActiveSpreadsheet().getSheetByName("Support");

  // get the values in column H and turn the rows into a single values
  return sheet.getRange(1, 8, sheet.getLastRow(), 1).getValues().map(function (row) { return row[0]; });
}

当我实现给出的主要答案时，递归调用checkCalls（）最终会导致错误（这基本上是正确的，而且非常有用，所以谢谢！）。

//注意：但是最初的实现可以在一段时间内正常工作-例如90分钟-然后崩溃。通常需要1秒钟的呼叫将花费300秒，而执行将暂停。看起来它通过继续递归调用自身而炸毁了堆栈。当在适当退出函数的情况下将其移至对check（）的单次调用时，它便开始工作。

Chrome在运行JavaScript的控制台日志中说： ERR_QUIC_PROTOCOL_ERROR.QUIC_TOO_MANY_RTOS 200

经过大量研究，我找到了一种更好的方法……不需要递归（因此不会造成麻烦）

删除此行： // window.setTimeout（checkCalls，500）;

并在脚本末尾使用类似这样的内容：

  // This function returns a Promise that resolves after "ms" Milliseconds

        // The current best practice is to create a Promise...
  function timer(ms) {
   return new Promise(res => setTimeout(res, ms));
  }

  
  async function loopthis () { // We need to wrap the loop into an async function for the await call (to the Promise) to work.  [From web: "An async function is a function declared with the async keyword. Async functions are instances of the AsyncFunction constructor, and the await keyword is permitted within them. The async and await keywords enable asynchronous, promise-based behavior to be written in a cleaner style, avoiding the need to explicitly configure promise chains."]
    for (var i = 0; i >= 0; i++) {
      console.log('Number of times function has been run: ' + i);
      checkCalls();
      await timer(3000);
    }
  }


  window.onload = function () {
    loopthis();
  }

</script>
