Answer 1

默认情况下,在WebView中禁用JavaScript.

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

Answer 2

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

Answer 3

在Kotlin 的WebView 中启用 JS ：

val webView = web_view_id
webView.settings.javaScriptEnabled = true
