WebView 阻止弹出窗口？答案

【问题标题】：WebView blocking pop up windows?WebView 阻止弹出窗口？

【问题描述】：

我正在使用WebView 浏览 pesopay.com，它工作正常，除非我按下提交按钮。使用谷歌浏览器等互联网浏览器会显示一个弹出窗口，它会确认您填写的信息。但是在我的 Android WebView 中，当我按下提交按钮时什么也没发生。我想是因为WebView 没有启用显示弹出窗口。

谁能指出哪里出了问题？

这是我的活动：

public class PaymentActivity extends Activity {

String amount1;     
    @SuppressLint("SetJavaScriptEnabled")
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        // TODO Auto-generated method stub
        super.onCreate(savedInstanceState);
        setContentView(R.layout.payment);

         Bundle extras = getIntent().getExtras(); 
            if(extras !=null)
            {
                amount1 = extras.getString("amount1");

            }

        WebView web = (WebView) findViewById(R.id.web1);
        web.getSettings().setJavaScriptEnabled(true);
        web.loadUrl("javascript:window.onload = function(){setValue(\""+ amount1 +"\");};");
        web.loadUrl("file:///android_asset/www/index.html");   
    }    
}

我的网页：

【解决方案1】：

如果我说对了，你需要使用 JavaScriptInterface 从 Android 调用 JavaScript 函数。

查看此链接可能会对您有所帮助：

http://www.codeproject.com/Articles/392603/Android-addJavaScriptInterface

或者检查一些网络设置： http://developer.android.com/reference/android/webkit/WebSettings.html#setSupportMultipleWindows%28boolean

尝试将此代码放入 onCreate()

        webView.getSettings().setPluginsEnabled(true);
        webView.getSettings().setAllowFileAccess(true);
        webView.getSettings().setJavaScriptCanOpenWindowsAutomatically(true);

但它只是在 webview 中显示吐司。
未显示在我的网页视图中的弹出窗口不是我创建的。它是我正在浏览的网站的弹出窗口。链接test.pesopay.com/b2cDemo/eng/payment/payForm2.jsp
好的，我明白了，你在 onCreate() webView.getSettings().setJavaScriptCanOpenWindowsAutomatically(true) 上试过这个；
或检查我们的其他设置，这可能会对您有所帮助developer.android.com/reference/android/webkit/…
+1。谢谢。 webView.getSettings().setJavaScriptCanOpenWindowsAutomatically(true); 为我工作。

【解决方案2】：

Webview中负责对话框的函数是WebChromeClient的onJsAlert。

这里是示例代码

  public class MyWebChromeClient extends WebChromeClient {
    @Override
    public boolean onJsAlert(WebView view, String url, String message, JsResult jsResult) {
        // you can create your own dialog here or just return true for no pop up. 
        return true;
    }
}

并将其添加到您的网络视图中：

MyWebChromeClient myWebChromeClient = new MyWebChromeClient();
webView.setWebChromeClient(myWebChromeClient);
