Android WebView Compile a Form and submit with Javascript

2024/2/27 7:53:27

I'm trying to complete this form :

http://www.lbalberti.it/whatsup.asp?codist=57247

I was able to insert value to the two textbox but the button doesn't work.

@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.activity_home_page);final String user = getIntent().getStringExtra("username");final String psw = getIntent().getStringExtra("password");MyWebView view = new MyWebView(this);view.getSettings().setJavaScriptEnabled(true);view.getSettings().setDomStorageEnabled(true);view.loadUrl("http://www.lbalberti.it/whatsup.asp?codist=57247");view.setWebViewClient(new WebViewClient() {@Overridepublic boolean shouldOverrideUrlLoading(WebView v, String url) {v.loadUrl(url);return true;}@Overridepublic void onPageFinished(WebView v, String url) {v.loadUrl("javascript:" +"var y = document.getElementsByName('login')[0].value='"+user+"';" +"var x = document.getElementsByName('password')[0].value='"+psw+"';");
}});setContentView(view);
}class MyWebView extends WebView {Context context;public MyWebView(Context context) {super(context);this.context = context;}
}

The following code doesn't work :
"var k = document.getElementByTagName('form')[0].submit();"
or
"var k = document.getElementByName('newlogin')[0].submit();"

Answer
 @Overridepublic void onPageFinished(WebView view, String url) {super.onPageFinished(view, url);if (android.os.Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {view.evaluateJavascript("javascript:document.getElementById('username').value ='" + strUsername + "';javascript:document.getElementById('password').value = '" + strPassword + "';javascript:document.getElementById('loginButton').click();", null);} else {view.loadUrl("javascript:document.getElementById('username').value = '" + strUsername + "';javascript:document.getElementById('password').value = '" + strPassword + "';javascript:document.getElementById('loginButton').click();");}}
