title: Android html load on webview cant work
body: <p>when i use webview to load a url , the html tag "select" does not work to call ajax and return data to other
  "select".
  the url is "<a href="http://www.pcschool.com.tw/query/tCourse.aspx" rel="nofollow">http://www.pcschool.com.tw/query/tCourse.aspx</a>".
  But this html can work in the chrome browser.
  what's wrong?</p>
  
  <p>here is my webview settings:</p>
  
  <pre><code>private void setWebView() {
  
  WebChromeClient wcc = new WebChromeClient() {
  
  };
  
  web.setWebChromeClient(wcc);
  
  WebSettings webSettings = web.getSettings();
  webSettings.setJavaScriptEnabled(true);
  webSettings.setBuiltInZoomControls(true);
  webSettings.setAllowContentAccess(true);
  webSettings.setLoadsImagesAutomatically(true);
  webSettings.setLoadWithOverviewMode(true);
  webSettings.setSupportZoom(true);
  webSettings.setUseWideViewPort(true);
  webSettings.setAllowFileAccess(true);
  webSettings.setDomStorageEnabled(true);
  
  web.addJavascriptInterface(new JavaScriptInterface() , "android_interface");
  
  WebViewClient wvc = new WebViewClient() {
  
      @Override
      public WebResourceResponse shouldInterceptRequest(WebView view,String url) {
  
          return super.shouldInterceptRequest(view, url);
      }
  
      @Override
      public boolean shouldOverrideUrlLoading(WebView view, String url) {
  
      System.out.println("------------shouldOverrideUrlLoading------------");
      view.loadUrl(url);
  
      return true;
      }
  
      @Override
      public void onPageStarted(WebView view, String url, Bitmap favicon) {
          // TODO Auto-generated method stub
          super.onPageStarted(view, url, favicon);
  
      }
  
      @Override
      public void onPageFinished(WebView view, String url) {
                     super.onPageFinished(view, url);
  
                    web.loadUrl("javascript:window.android_interface.
                     checkLoginSession(document.getElementsByTagName('html')[0].innerHTML);");
  
      }
  
  
      };
  
         web.setWebViewClient(wvc);
  
         //web.loadUrl("http://www.pcschool.com.tw/query/tCourse.aspx");
  }
