Google Apps Script to open a URL
(6 answers)
Closed 2 years ago.
I've created a spreadsheet in google drive, and I've put together a tutorial presentation using google presentations to demonstrate to the users how to use the spreadsheet and why it's better than the way we were doing it before.
What I would like is a message box to appear when the spreadsheet is opened asking if that person has watched the tutorial presentation yet. If the user clicks No I'd like to either open a new page in the browser to show them the presentation I've published, or show the presentation in a custom UI.
I've searched for hours and can't figure it out. Is this possible? Thank you for your help!
I'm new to the forum so please let me know if I posted this wrong. Thanks!

Answer 1

Something like this does it pretty well.
I used a fake button to keep the "look and feel" consistent with the other button , I simply added the link invisible on top of it ;-)
function alertLink() {
var doc = SpreadsheetApp.getActiveSpreadsheet();
var app = UiApp.createApplication().setTitle('Message').setHeight('100').setWidth('400');
var panel = app.createVerticalPanel().add(app.createHTML('Did you see my beautiful <b>Tutorial</b> ?'));
var grid = app.createGrid(1,2).setWidth('400');
var closeHandler = app.createServerHandler('close');
var b1 = app.createButton("NO and I'd like to").setTitle('go to the tutorial in a new tab');
var b2 = app.createButton("YES and I don't want to see it again",closeHandler).setTitle('close this window');
var link = app.createAnchor('XXXXXXXXXX','http://www.google.com').setStyleAttributes({'zIndex':'1' , 'position':'fixed' , 'top':'25' , 'left':'20', 'color':'transparent' }).setTitle('go to the tutorial in a new tab');
var G1 = app.createVerticalPanel().add(b1).add(link);
grid.setWidget(0,0,G1).setWidget(0,1,b2);
app.add(panel).add(grid)
doc.show(app)
}
function close(){
return UiApp.getActiveApplication().close();
}
Just use an onOpen trigger if you want it to execute automatically on spreadsheet open. (or rename the main function as onOpen() )
Here is how it looks like :

Answer 2

For an onOpen trigger, it's certainly a better UX to prompt the user with a dialog box offering the option to open a URL, as opposed to opening the URl automatically. See serge's answer here for how to do that (which is more up-to-date than the deprecated code in his answer on this thread).
But for other triggers (such as a menu item click) check out my answer here to open a URL automatically.
