自动关闭模式对话框 - 服务器代码完成后，在Google Spreadsheet中关闭对话框

问题描述

我有一个Google表单，它运行一些Apps Script服务器代码连接到SQL服务器。我想在数据刷新时在模态对话框中显示消息loading ...。我可以让模式弹出，但是我想在代码完成后自动关闭对话框。

我设置的一个例子是：

   / code>触发服务器端 .gs 函数运行 
 
  .gs中的服务器函数
 
 
 
 
 
 
服务器代码将返回值发送回对话框
 > 
 
withSuccessHandler（）在对话框中检测到服务器的返回结果
 
withSuccessHandler（）运行并使用 google关闭对话框.script.host.close（）;  
 
  
 
 
您需要一个 < script> 标记在您的模式中d ialog。
 < script> 
 window.onload = function（）{
 //console.log('window.onload ran！'）; 
 
 google.script.run 
 .withSuccessHandler（closeDialog）
 .theFunctionNameToUpdateDatabase（）
}; 
 
 window.closeDialog = function（）{
 google.script.host.close（）; 
}; 
< / script> 
  
现在您正在使用： 
 
 
  HtmlService.createHtmlOutput（HTML在这里）
  
您可以创建HTML代替文件：
  HtmlService.createHtmlOutputFromFile（filename）
  
 
I have a Google Sheet that runs some Apps Script server code to connect to an SQL server.  I want to show the message "loading..." in the modal dialog while data is being refreshed.  I can get the modal to pop up, but I want to auto-close the dialog as soon as the code is finished.
An example I have set up is:
function testpop () {
  var htmlOutput = HtmlService
    .createHtmlOutput('<p> This box will close when the data has finished loading.</p>')
    .setSandboxMode(HtmlService.SandboxMode.IFRAME)
    .setWidth(250)
    .setHeight(200);
  SpreadsheetApp.getUi().showModalDialog(htmlOutput, 'Loading...');
  sleep(1000);
//close the dialog
}
I know this can be called on a client side but need it to be handled in the GS so it fires when the code is done.
 解决方案 
The flow of events could be:
User does something
Triggers modal dialog
onLoad event of modal dialog triggers client side code
Client side google.script.run triggers a server side .gs function to run
Server function in .gs script file runs.
database updated from server.
server code sends a return value back to dialog
"withSuccessHandler()" in dialog detects the return from the server
"withSuccessHandler()" runs and closes the dialog using google.script.host.close();
You'll need a <script> tag in your modal dialog.
<script>
  window.onload = function() {
    //console.log('window.onload ran!');

    google.script.run
      .withSuccessHandler(closeDialog)
      .theFunctionNameToUpdateDatabase()
  };

  window.closeDialog = function() {
    google.script.host.close();
  };
</script>
Right now you are using:
HtmlService.createHtmlOutput(the HTML here)
You could create the HTML from a file instead:
HtmlService.createHtmlOutputFromFile(filename)
