In the mobile app that I am developing I need to be able to open a webview that displays a website that is saved locally to the app. I then need to be able to press a button within that webview and have it call a function in the app itself. Is there a way to do this? Can a webview (using javascript or something) call a function in the app? If so, How?
In JavaScript, set the document.location property to some custom URL string. You could use your own URL scheme to pass parameters from JS to AS3, e.g. as3://actions/document/save?overwrite=false. Then in ActionScript, handle the LocationChangeEvent.LOCATION_CHANGING event, and examine and/or decode the URL.
Call event.preventDefault() in your AS3 event handler to cancel the navigation and stay on the same page.
