Solution 1

JavaScript is disabled in a WebView by default.

WebView myWebView = (WebView) findViewById(R.id.webview);
WebSettings webSettings = myWebView.getSettings();
webSettings.setJavaScriptEnabled(true);

Solution 2

 WebView webView = (WebView) findViewById(R.id.webview);
        webView.getSettings().setJavaScriptEnabled(true);
        webView.getSettings().setJavaScriptCanOpenWindowsAutomatically(true);

Solution 3

Enabling JS in WebView in Kotlin:

val webView = web_view_id
webView.settings.javaScriptEnabled = true
