五秒钟后自动关闭Google Apps脚本UiApp [英] Automatically close a Google Apps Script UiApp after five seconds

问题描述

我想在一定秒数后自动关闭此UiApp:

I want to automatically close this UiApp after a certain number of seconds:

function showConfirmationDialogue() {
  var app = UiApp.createApplication().setHeight('80').setWidth('400');
  app.setTitle('test');
  var panel = app.createVerticalPanel();
  app.add(panel);

  var doc = SpreadsheetApp.getActive();
  doc.show(app);

  // this part doesn't seem to work
  Utilities.sleep(5000);
  app.close();
  return app;
}

谢谢！

推荐答案

调用doc.show(app)时会显示您创建的Ui，唯一可以更新或关闭它的方法是使用以a结尾的处理函数. return app.

The Ui you create is shown when you call doc.show(app) and the only way you can update it or close it is to use a handler function that ends with a return app.

因此，由于只能返回"一次，因此无法从创建UI的同一函数中执行所需的操作.

So it is not possible to do what you want from the same function that creates the UI since it is "returned" only one time.

我知道，只有一个技巧可以使用句柄触发源来实现所需的效果，该句柄触发源将使用复选框框.这是代码，它使用一个复选框，您当然可以在最终代码中将其隐藏.

I know only one trick that can achieve what you want that is using a handler trigger source that will call a closing handler function automatically using a "special" property of the checkBox widget. Here is the code, it uses a checkBox that you can of course make invisible in your final code.

function showConfirmationDialogue() {
  var app = UiApp.createApplication().setHeight('80').setWidth('400');
  app.setTitle('test');
  var panel = app.createVerticalPanel();
  app.add(panel);
  var handler = app.createServerHandler('closeWindow');
  var chk = app.createCheckBox('checkBox to set invisible in real function').setValue(false,true).addValueChangeHandler(handler);
  app.add(chk);
  chk.setValue(true,true)//.setVisible(false);
  var doc = SpreadsheetApp.getActive();
  doc.show(app);
}

function closeWindow(){
  Utilities.sleep(5000);
  var app = UiApp.getActiveApplication().close();
  return app;
}

您可以使用相同的过程以任何方式修改UiApp实例，更改标签文本，添加小部件...任何您想要的东西.

You can use the same procedure to modify the UiApp instance in any way, change a Label text, add a widget... anything you want.
