semar Active Member Licensed User Longtime User Feb 16, 2021 #1 Dear all, the CallSub function works by WebViewExtra, but I can't get it working with WebViewExtra2. Is this functionality in someway broken ? Or am I missing something obvious here ? In the attachment is a test project. Clicking on the button should change the text in the label. The function in the jstest.js is successfully called - you can see that the JavaScript "alert" is fired. But the function does not call the counterpart function "fromJavascript" in the B4A program. It would be nice if someone could share a bit of light on how to get it working with WebViewExtra2.
