Hi friends, this is an example about App inventor and JavaScript.

1.- App inventor send datas to file pitagoras.htm. 3:4

2.- pitagoras.htm with JavaScript get datas and split cateto1= 3 and cateto2 = 4

3.- JavaScript calculates hypotenuse

4.- JS send hypotenuse to App inventor by

- window.AppInventor.setWebViewString("Hipotenusa = " + hipotenusa);

and

- document.write("<br /> Hipotenusa: <br />" + hipotenusa );

nice example! keep up the good work!

note: as you know, before building the app you have to use a different path...

https://puravidaapps.com/tutorials.php#html

Yes, you also can upload html files as assets into App Inventor! There is only one special thing to consider: During development, you have to use the development path to the embedded html document:
file:///mnt/sdcard/AppInventor/assets/<NAME OF YOUR HTML FILE>.html
Before packaging the app, use the production path.
file:///android_asset/<NAME OF YOUR HTML FILE>.html
