I can get/access the value of the UI elements using,

e.parameter.elementname or app.getElementById(id)

if i create UI using UiApps or GUI builder like,

app.add(app.loadComponent("MyGui"));
app.getElementbyId('textbox1').setText("Hi");

If i use, HtmlService.createHtmlOutputFromFile('myPage'); How can i get the values entered in the html form - elements ?

As an alternative to client-side JavaScript, you can also create simple forms that submit to the doPost() handler which then processes the data. I created a sample script to demonstrate: Run, Source

  • why would my doPost() script redirect to an empty page? Even a simple thank you page containing just:

    Thank you!

    , is returning an empty screen?     – Jurgen Cuschieri Apr 18 '18 at 16:03
  • actually even your example is not redirecting to the Thank you page but a blank page! What should be added to end of the doPost() function? I do not necessarily need a Thank you page, even a message on the same page would do. – Jurgen Cuschieri Apr 18 '18 at 16:17

When using HtmlService you need to rethink your app to be primarily client based not server based. You can (in client-side JavaScript) add a change handler to any element and do something with the value, including calling a server function with google.script.run.myFunction(someValue). See the new user guide here: https://developers.google.com/apps-script/html_service
