[英]Automatically close a Google Apps Script UiApp after five seconds
I want to automatically close this UiApp after a certain number of seconds: 我想在一定的秒数后自动关闭这个UiApp:
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;
}
Thanks! 谢谢!
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
. 当您调用doc.show(app)
时,会显示您创建的Ui,并且您可以更新它或关闭它的唯一方法是使用以return app
结尾的处理函数。
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. 因此,无法从创建UI的同一函数中执行您想要的操作,因为它只返回一次。
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 . 我知道只有一个技巧可以实现你想要的,使用处理程序触发源,它将使用checkBox小部件的“特殊”属性自动调用结束处理函数。 Here is the code, it uses a checkBox that you can of course make invisible in your final code. 这是代码,它使用一个checkBox,当然你可以在最终代码中隐藏它。
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;
}
You can use the same procedure to modify the UiApp instance in any way, change a Label text, add a widget... anything you want. 您可以使用相同的过程以任何方式修改UiApp实例,更改Label文本,添加小部件......您想要的任何内容。
