Android执行JavaScript的重定向webview

Question

我打电话的主URL，如“https://foo.com/default?companyId=1929770&authorizationSource=FTP”， 当我加载主要URL时，我将被重定向到辅助URL，如“https://foo.com/default?companyId=1929770&authorizationSource=FTP_123456789”。辅助URL总是随机生成带有编号的FTP。我怎样才能执行JavaScript的辅助URL？

public class ActivityWebViewPay extends Activity { 
public void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    String privatURL = "https://foo.com/default?companyId=1929770&authorizationSource=FTP&account=" + getIntent().getStringExtra(ACCOUNT_LS); 

    WebView urlWebView = new WebView(this); 
    setContentView(urlWebView); 
    urlWebView.getSettings().setJavaScriptEnabled(true); 
    urlWebView.getSettings().setDomStorageEnabled(true); 
    WebSettings settingsURL = urlWebView.getSettings(); 
    settingsURL.setMinimumFontSize(18); 
    settingsURL.setBuiltInZoomControls(true); 
    settingsURL.setDisplayZoomControls(true); 
    settingsURL.setJavaScriptEnabled(true); 
    settingsURL.setDomStorageEnabled(true); 
    urlWebView.clearHistory(); 
    urlWebView.clearCache(true); 
    urlWebView.loadUrl(privatURL); 

    urlWebView.setWebViewClient(new WebViewClient(){ 
     @Override 
     public void onPageFinished(WebView view, String url) { 
      view.loadUrl("javascript:function a(){window.document.getElementsByClassName('property-info-wrap')[0].style.display='none';}; a()"); 
     } 
    }); 
} 

logcat的：

[INFO:CONSOLE(1)] "Uncaught TypeError: Cannot read property 'style' of undefined", source: (1) 
[INFO:CONSOLE(1)] "Uncaught TypeError: Cannot read property 'style' of undefined", source: (1) 
[INFO:CONSOLE(22)] "Start Referrer is >>> ", source: link without FTP (22) 
[INFO:CONSOLE(1)] "Uncaught TypeError: Cannot read property 'style' of undefined", source: (1) 
[INFO:CONSOLE(5)] "The key "target-densitydpi" is not supported.", source: link with FTP (5) 
[INFO:CONSOLE(30)] "referer ", source: link with FTP (30) 
[INFO:CONSOLE(1)] "Uncaught TypeError: Cannot read property 'style' of undefined", source: (1)

可以执行像这里面的js代码onPageFinished

String jsScript = "javascript:alert(" + msg + ");"; 
webView.loadUrl(jsScript); 

而且，对我来说：我加入一个开关就知道数量我打开的网址：

public void onPageFinished(WebView view, String url) 
{ 
    super.onPageFinished(view, url); 
    count++; 
    switch (count) 
    { 
     case 1: 
      String jsScriptInit;// do that you want 
      webView.loadUrl(jsScriptInit); 
      break; 
     case 2: 
      String jsScript; 
      webView.loadUrl(jsScript); 
      break; 
    } 
}
