I have a website with href
in it which redirected me to https
<a id="mA" href="javascript:pLogin(2)" class="login-link__link private-cab-link"><i class="icon-user"></i>Авторизация</a>
So, I can click on it by JavaScript. It works in chrome console
javascript:(function(){document.getElementById('mA').click();})()
Now I'm trying to do the same in WebView by clicking my app's button.
public class RostelecomLoginActivity extends Activity {
WebView webView;
String url;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
this.getWindow().requestFeature(Window.FEATURE_PROGRESS);
setContentView(R.layout.activity_rostelecom_login);
Intent webIntent = getIntent();
String url = webIntent.getStringExtra("url");
webView = (WebView) findViewById(R.id.webView1);
webView.setWebViewClient(new MeWebViewClient());
webView.getSettings().setJavaScriptEnabled(true);
webView.getSettings().setSaveFormData(true);
webView.getSettings().setSavePassword(true);
webView.loadUrl(url);
Button buttoner = (Button) findViewById(R.id.button1);
buttoner.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
webView.loadUrl("javascript:(function(){document.getElementById('mA').click();})()");
}
});
}
}
I'm using MyWebViewClient to allow all certificates
public class MeWebViewClient extends WebViewClient {
@Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
view.loadUrl(url);
return true;
}
@Override
public void onReceivedSslError(WebView view, SslErrorHandler handler, SslError error) {
handler.proceed();
}
}
The js injection doesn't work. If I click on href in WebView it works. What can be wrong?
click() isn't implemented in android js interface, you have to use HTML DOM Event Object, like this:
webView.loadUrl("javascript:(function(){"+
"l=document.getElementById('mA');"+
"e=document.createEvent('HTMLEvents');"+
"e.initEvent('click',true,true);"+
"l.dispatchEvent(e);"+
"})()");
You'll have to add a javaScript interface to the WebView
to call a JavaScript
function from android code.
Try something like this:-
Button buttoner = (Button) findViewById(R.id.button1);
buttoner.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
JavascriptInterface javasriptInterface = new JavascriptInterface(RostelecomLoginActivity.this);
webView.addJavascriptInterface(javasriptInterface, "MyInterface");
webView.loadUrl("javascript:(function(){document.getElementById('mA').click();})()");
}
});
