Answer 1

Should work, where did you get the idea that it does not work at all? If it does not work alert, etc., this is a separate problem.

Answer 2

What version of android? What version of webview on android? What SDK version are you using? What makes you think that js does not work? Checking on a simple page with a simple js script is not fate to make sure that it definitely does not work?
Transfer:

webSettings.setJavaScriptEnabled(true);
myWebView.setWebViewClient(new WebViewClient());
WebSettings webSettings = myWebView.getSettings();

Try to hook up WebChromeClient to enable the maximum number of js functions for sure.
