WebView阻止弹出窗口？ [英] WebView blocking pop up windows?

问题描述

我使用 WebView 来浏览pesopay.com并且它正常工作，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式窗口，它确认您填写的信息。但是在我的Android WebView 中，当我按下提交按钮时，什么都没有发生。我想是因为 WebView 没有显示弹出窗口。

任何人都可以指出我的错在哪里？

以下是我的活动：

 公共类PaymentActivity extends Activity { 
 
字符串amount1; 
 @SuppressLint（SetJavaScriptEnabled）
 @Override 
 protected void onCreate（Bundle savedInstanceState）{
 // TODO自动生成的方法存根
 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）;

解决方案

如果我正确的话，用于从Android调用JavaScript函数的JavaScriptInterface 。

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

或者查看一些网页设置：
http://developer.android.com/reference/android/webkit/WebSettings.html#setSupportMultipleWindows%28boolean

试着把这段代码放在onCreate（）中。

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

I'm using WebView to browse pesopay.com and it works properly, except when I pressed the submit button. Using internet browsers like Google Chrome will show a pop up window, it confirms the information you filled. But in my Android WebView nothing happened when I pressed the submit button. I think because WebView is not enabled to display a pop up window.

Can anyone point me what is wrong?

Here is my 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");   
    }    
}

My web page:

解决方案

If i am getting right , you need to use JavaScriptInterface for calling JavaScript function from Android.

Check this link which may help you :

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

Or check some websettings : http://developer.android.com/reference/android/webkit/WebSettings.html#setSupportMultipleWindows%28boolean

try to put this code in onCreate()

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