I have been trying to call a JavaScript function called showMenu(); from an Android WebView. However, I have tried what many articles on StackOverflow say about doing 

webview.loadURL("javascript:showMenu()");

and it shows this in the console:

I/chromium: [INFO:CONSOLE(1)] "Uncaught ReferenceError: showMenu is not defined", source: https://url.com/index.php (1).

I am new at Android and I am pretty sure it is a simple fix, but I could not find it anywhere. How can I do this?

EDIT: JavaScript is enabled

  • Make sure Javascript execution is enabled. or you can do so by `webView.getSettings().setJavaScriptEnabled(true);`. And make sure `showMenu()` is valid function, i suggest you try calling the same method on Google Chrome Insect window's console. – Sivakumar S Jan 28 '18 at 06:50
  • @SivakumarS I got that it is not defined. I currently have it set like `` – FrankFabregat2 Jan 28 '18 at 06:59

I removed the function from the <script> tags, and put it in a .js file using 'use strict'; and worked :)
