如何在Web视图中的网页上运行JavaScript Android

我有一个表格，我想填写并自动提交。我已经尝试过使用WebviewClient，然后等待页面完成加载，然后再使用evaluateJavascript作为Web视图。这一切看起来是正确的，我的JavaScript似乎是有效的每一个验证在线。所以我不知道问题在哪里。如何在Web视图中的网页上运行JavaScript Android

以下是我在为我的代码的Android应用：

//Login infomration get from stored perferences. 
String username = "[email protected]"; 
String password = "G12345!"; 
String javaScriptToLoadEmail = "document.getElementById(\"email\").value = \"" + username + "\";"; 
String javaScriptToLoadPass = "document.getElementById(\"pass\").value = \"" + password + "\";"; 
String javaScriptForm = "var frms = document.getElementsByName(\"send2\");"; 
String javaScriptSubmit = "frms[0].submit();"; 
String superJavaScript = "<script> " + 
     javaScriptToLoadEmail + 
     javaScriptToLoadPass + 
     javaScriptForm  + 
     javaScriptSubmit + 
     " </script>"; 
WebView webView; 

@Override 
protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.activity_main); 

    Log.d("Java Script", superJavaScript); 

    webView = (WebView)findViewById(R.id.webview); 
    webView.getSettings().setJavaScriptEnabled(true); 
    webView.getSettings().setDomStorageEnabled(true); 
    webView.loadUrl(LoginPage); 
    webView.setWebViewClient(new WebViewClient() 
    { 
     @Override 
     public void onPageStarted(WebView view, String url, Bitmap facIcon) { 
      Log.d("Page is: ", "Loading"); 
      //SHOW LOADING IF IT ISNT ALREADY VISIBLE 
     } 

     @Override 
     public void onPageFinished(WebView view, String url) { 

      Log.d("Page is:" , "Loaded"); 
      Log.d("Java Script", superJavaScript); 
      webView.evaluateJavascript(superJavaScript, null); 
     } 
    }); 

}

而这正是我试图访问和改变HTML表单的。

<form action=“//…//“ method="post" id="login-form"> 

     <div class="col-2 registered-users"> 
      <div class="content"> 
       <h2><font><font>Customers who have already your registered</font></font></h2> 
       <p><font><font>If you have an account, please login.</font></font></p> 
       <ul class="form-list"> 
        <li> 
         <label for="email" class="required"><em><font><font>*</font></font></em><font><font> E-mail address</font></font></label> 
         <div class="input-box"> 
          <input type="text" name="login[username]" value="" id="email" class="input-text required-entry validate-email" title="mail address"> 
         </div> 
        </li> 
        <li> 
         <label for="pass" class="required"><em><font><font>*</font></font></em><font><font> Password</font></font></label> 
         <div class="input-box"> 
          <input type="password" name="login[password]" class="input-text required-entry validate-password" id="pass" title="password"> 
         </div> 
        </li> 

       </ul> 



     <div class="col-2 registered-users"> 
      <div class="buttons-set"> 
       <button type="submit" class="button f-right" title="Login" name="send" id="send2"><span><span><font><font>Login</font></font></span></span></button> 

      </div> 
     </div> 
    </div> 
     </form>

这是我通过字符串发送的脚本。

<script> document.getElementById("email").value = "[email protected]";document.getElementById("pass").value = "G12345!";var frms = document.getElementsByName("send2");frms[0].submit(); </script>

你这样做是完全错误的，你应该有这样做的启用一个接口。 –

尝试加入这一行

webView.getSettings().setJavaScriptCanOpenWindowsAutomatically(true);

没有变化。它仍然没有运行脚本。 – MNM
