Get the params of window.open

[brcontainer]

I wonder if it’s possible to get the parameters passed by window.open, as the following example:

var params = "menubar=yes,location=yes,resizable=yes";
    window.open("http://www.cnn.com/", "_blank", params);

var params = "menubar=yes,location=yes,resizable=yes";
    window.open("http://www.cnn.com/", "_blank", params);

To copy to clipboard, switch view to plain text mode 

I need to get params this menubar=yes,location=yes,resizable=yes in “c++”.

Is it possible to do this using

class cutomWebView : public QWebPage

class cutomWebView : public QWebPage

To copy to clipboard, switch view to plain text mode 

or

class cutomWebView : public QWebView

class cutomWebView : public QWebView

To copy to clipboard, switch view to plain text mode 

or something?

customWebPage.cpp:

QWebPage * customWebPage::createWindow(const QWebPage::WebWindowType type) {
        qDebug() << type;
 
        return new MainWindow()->createPage();//createPage is custom function
    }

QWebPage * customWebPage::createWindow(const QWebPage::WebWindowType type) {
        qDebug() << type;
     
        return new MainWindow()->createPage();//createPage is custom function
    }
