HTML generation from Button Click event

I would like to generate a HTML file for my App I create using MIT App Inventor2.

I am looking at the code right now and wondering if I could call a HTML Generation function from the Event Listener of a button, would that work?

Where do I call my HTML Generation function in the code for that to happen?

Can anyone help? Thanks in advance?

You can read an html file with AI2 but you can not "generate" a html.  You can write and make the html (it is essentially a fancy text file) manually but this is not really practical inputting text with a phone or tablet on screen keypad..

Is it possible to replace source within the existing html with button click

I do not know Richard.   This post by Taifun seems to say he thinks it is possible to modify an existing html, however it does not provide any detail: Programmatically generating HTML using AI2 and presenting it via Webviewer  
I have not attempted this.  

Here are some things that I know can be done:

http://puravidaapps.com/table.php
table3.aia

http://puravidaapps.com/snippets.php#2webviewstring
webviewstring.aia

so if the html is structured correctly, you can post data and get a return.

Check it out, try some things and lets us know what you discover.

you can use the File component to store some text in a text file on sd card, and a html file is a text file, isn't it? Then you can use the webviewer to display that html file

alternatively you can pass html snippets via the webviewstring property to the webviewer, see here
