方案点击Android中的WebView [英] programmatic click in Android WebView

问题描述

下午好！

我有HREF中有一个网站，我重定向到https

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>

所以，我可以通过JavaScript的点击就可以了。它可以在Chrome浏览器的控制台

So, I can click on it by javascript. It works in chrome console

javascript:(function(){document.getElementById('mA').click();})()

现在我想通过点击我的应用程序的按钮做的WebView一样。

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();})()");
        }
    });

}

}

我用MyWebViewClient让所有证书

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();
}

}

JS的注射不起作用。如果我的WebView点击HREF它的工作原理。 什么是错的？ 谢谢你。

The js injection doesn't work. If I click on href in WebView it works. What can be wrong ? Thanks.

推荐答案

点击（）没有在Android的JS接口实现的，必须使用HTML DOM事件对象，像这样的：

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);"+
    "})()");
