我有一个Google应用程序脚本代码，要求用户通过html自定义对话框输入一些值。对话框中的按钮触发了.gs文件中的一个函数，我想等待该触发函数返回，然后再继续执行其余代码

  function main () {
      selectSheets (); 
      //Below are the functions that I need openSheets to return before calling them (I'm not including their implementation here, as I don't think it's needed):
      categoriesAndScoresDictionary = getCategoriesDictionary(); 
      categoriesEntries = getCategoriesEntries(categoriesAndScoresDictionary); 
      //and other functions..

    }

function selectSheets () {

  var htmlDialog = HtmlService.createTemplateFromFile("sheets_menu")
  var spreadsheets = SpreadsheetApp.getActiveSpreadsheet().getSheets(); 
  var sheetsArray = []; 

  for (index in spreadsheets) {
    sheetsArray.push(spreadsheets [index].getSheetName());  
  }

  htmlDialog.sheetsArray = sheetsArray; 

  var html = htmlDialog.evaluate().setSandboxMode(HtmlService.SandboxMode.IFRAME).setWidth(300); 

  SpreadsheetApp.getUi().showModalDialog(html, "Select sheets names");
  return html
}

下面的函数通过html中的onclick调用，我想等待它返回，然后再继续在主函数中执行：

function openSheets (appsSelection, rubricsSelection) {

  var spreadsheetFile = SpreadsheetApp.getActiveSpreadsheet(); 
  Logger.log(appsSelection + " " + rubricsSelection); 

  //Open the sheet by name inside the opened Spreadsheet (inside the file)
  //Open applications sheet: 
  applicationsSheet = spreadsheetFile.getSheetByName(appsSelection);

  //Open rubrics sheet: 
  rubricsSheet = spreadsheetFile.getSheetByName(rubricsSelection);
  //This function gets called from the html side and it runs successfully, I need to wait for it to return before executing other functions called in main () 

}

这是html：

<!DOCTYPE html>
<html>
  <head>
    <base target="_top">
  </head>
  <body>
    <input type = "hidden" value="<?!= sheetsArray ?>" id= "sheetsArray"/>

    <br>
    <p>Select the name of the applications sheet:</p>
     <select id = "sheetsList">

     </select>
     <br>
     <p>Select the name of the rubrics sheet:</p>

     <select id = "sheetsList2">

     </select>

     <br><br><br>
    <center><input type= "button" value = "Confirm" onclick ="sendSelectionToJs()"/></center>

    <script> 
     // Create the list element:
     function fillSelection () {
     var firstMenu = document.getElementById("sheetsList"); 
     var secondMenu = document.getElementById("sheetsList2"); 

     var holderArray = document.getElementById ("sheetsArray").value; 
     var sheetsArray = holderArray.split(","); 

    for (var i = 0; i<sheetsArray.length; i++){
    var option = document.createElement("option");
    option.value = sheetsArray[i];
    option.innerHTML = sheetsArray[i];
    firstMenu.appendChild(option);    
    }

    for (var i = 0; i<sheetsArray.length; i++){
    var option = document.createElement("option");
    option.value = sheetsArray[i];
    option.innerHTML = sheetsArray[i];
    secondMenu.appendChild(option);    
    }
  }


    function sendSelectionToJs() {

    var appsSelection = document.getElementById ("sheetsList").value; 
    var rubricsSelection = document.getElementById ("sheetsList2").value; 
     google.script.run.openSheets(appsSelection, rubricsSelection); 
     google.script.host.close(); 

    }

    fillSelection (); 

    </script> 
  </body>
</html>


不可能让服务器端代码等待客户端代码完成。IMHO您应该更改脚本的逻辑：
使用服务器端功能打开对话框/侧栏。通常这类函数不包含其他内容，因为对话框/侧栏的打开是异步的
客户端代码应该调用服务器端函数，该函数可能返回受支持的JavaScript对象。此服务器函数可用于调用应同步运行（按特定顺序）的其他服务器函数

这令人困惑。在继续代码的其余部分之前，我想等待触发的函数返回。在继续执行主程序之前。但是您只调用了openSheets
函数。对吗？为什么main
函数会运行？请删除承诺代码或显示原始代码以及承诺修改。服务器端是同步的。承诺不会起作用，也不会起任何作用。我期待着客户的承诺。无论如何，退一步，解释一下你最初的问题：你到底为什么要等待？是什么问题导致您将此作为解决方案？这是否回答了您的问题@我提供了原始代码，添加了一些有助于澄清问题的注释，并在末尾添加了一个文本来澄清我为什么需要这个。
