android - WebView 阻止弹出窗口

itcoder 2023年05月26日编程设计 5 0

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 Google Chrome 等互联网浏览器将显示一个弹出窗口，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没有任何反应。我认为是因为未启用 WebView 来显示弹出窗口。

谁能指出我哪里出了问题？

这是我的 Activity :

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");    
    }     
}

请您参考如下方法:

如果我没看错，您需要使用 JavaScriptInterface 从 Android 调用 JavaScript 函数。

检查此链接可能对您有帮助:

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

尝试将此代码放在 onCreate() 中

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