Google Script:当特定单元格更改值时播放声音

本文介绍了Google Script:当特定单元格更改值时播放声音的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

情况:

示例电子表格

表:支持
列:H有如下函数"=IF(D:D>0;IF($B$1>=$G:G;"Call";"In Time");" ")"根据结果改变值.

问题:

我需要:

当 H 列中的单元格更改为支持"表上的呼叫"时播放声音.
此功能需要每 5 分钟运行一次.
声音需要上传到云端硬盘还是我可以使用来自 URL 的声音?

我将不胜感激，任何人都可以提供帮助......我看到了很多代码，但我不太明白.

解决方案

这是一个相当棘手的问题，但可以通过定期轮询 H 列以了解更改的侧边栏来解决.

Code.gs

//打开电子表格时创建自定义菜单函数 onOpen() {var ui = SpreadsheetApp.getUi().createMenu('调用应用程序').addItem('打开调用通知程序', 'openCallNotifier').addToUi();//您还可以在电子表格打开时打开呼叫通知器侧边栏//如果你觉得这样更方便//openCallNotifier();}//打开侧边栏应用函数 openCallNotifier() {//从名为Page.html"的文件中获取 htmlvar html = HtmlService.createHtmlOutputFromFile('Page').setTitle("呼叫通知");//打开侧边栏电子表格App.getUi().showSidebar(html);}//返回列 H 中的值列表函数 getColumnH() {var sheet = SpreadsheetApp.getActiveSpreadsheet().getSheetByName("Support");//获取列 H 中的值并将行转换为单个值return sheet.getRange(1, 8, sheet.getLastRow(), 1).getValues().map(function (row) { return row[0]; });}

I will appreciate to anyone can help on it... I see a lot of code but I didn't understand very well.

解决方案

This is a pretty tough problem, but it can be done with a sidebar that periodically polls the H column for changes.

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]; });
}

    function checkCalls() {

      // This calls the "getColumnH" function on the server
      // Then it waits for the results
      // When it gets the results back from the server,
      // it calls the callback function passed into withSuccessHandler
      google.script.run.withSuccessHandler(function (columnH) {
        for (var i = 0; i < columnH.length; i++) {

          // if there's a difference and it's a call, notify the user
          if (lastTime[i] !== columnH[i] && columnH[i] === "Call") {
            notify();

        console.log(lastTime);

        // poll again in x miliseconds
        var x = 1000; // 1 second
