App Inventor and HTML/JavaScript with Input Parameters
jQuery UIThe example displays an App Inventor list in a jQuery UI Sortable. Thank you furf, together with your jQuery UI Touch Punch library we can use drag and drop on the mobile device to order the list items manually.
I used only 80% of the device width, because else it would not be possible anymore to scroll the list...
I uploaded the following libraries as assets into App Inventor to get this running:
: The WebViewString property helps to simplify the example
and we can pass parameters to the HTML file stored as asset inside of the app, which was not possible before.
App Inventor,
The tools extension offers the method PathToAssets which always returns the correct path to the assets.
