Open dialog and close sidebar in Google Apps Script

Question

I'm developing a Google Sheets Add-on and I'm trying to have the script both close a HTML sidebar and open a dialog.

This code below doesn't work because the dialog is opened and then closed.

HTML file

google.script.run.gsSheetCreateSuccess();
google.script.host.close();

.gs file

function gsSheetCreateSuccess() {
var ui = SpreadsheetApp.getUi()
    ui.alert(
     'Setup Complete',
      "Success! You've Successfully completed setup on this spreadsheet.",
      ui.ButtonSet.OK)
}

And this code below (the reverse) doesn't work because the HTML file (the sidebar) is closed before it can execute google.script.run.gsSheetCreateSuccess(); and open the dialog.

HTML file

google.script.host.close();
google.script.run.gsSheetCreateSuccess();

How can I simultaneously close the sidebar and open a dialog?

Answer 1

Use the SuccessHandler() of the call to gsSheetCreateSuccess() to close the sidebar.

google.script.run
             .withSuccessHandler(google.script.host.close)
             .gsSheetCreateSuccess();
