How to run JavaScript with the contencs of a QNetworkReply

[WetCode]

Hello all I hope someone here can set me straight on this since I can't for the heck of it figure it out.
Am no pro so please bear with me.

I have a program that downloads a HTML file and parses out some information.
And its all working good, but some of the information is being displayed by a JavaScript.
So in the QString witch I have the complete source code of the page I see the code for the JavaScript.
Not the info I want, is there a way I can run the entire script so I can get the info I need?

here is a snip of the code showing how i store the html page.

// function executed when QNetworkReply emits finished()
void getHTMLFile::replyFinsihed(QNetworkReply *reply)
{
    QByteArray qbData = reply->readAll();
    sData.clear();
    sData = qbData;
    // continue with parsing data.
}

// function executed when QNetworkReply emits finished()
void getHTMLFile::replyFinsihed(QNetworkReply *reply)
{
    QByteArray qbData = reply->readAll();
    sData.clear();
    sData = qbData;
    // continue with parsing data.
}

To copy to clipboard, switch view to plain text mode 

I have googeld around for a while and found this.

QWebSettings::globalSettings()->setAttribute(..);

QWebSettings::globalSettings()->setAttribute(..);

To copy to clipboard, switch view to plain text mode 

But have not found a setting like

::evaluateJavaScript || ::enableScript

::evaluateJavaScript || ::enableScript

To copy to clipboard, switch view to plain text mode 

There is a function in

QWebView::evaluateJavaScript()

QWebView::evaluateJavaScript()

To copy to clipboard, switch view to plain text mode 

But from what i could find of information its not what i need (I may be wrong ofcorse..)

Any help and or guidance is much appreciated.

Cheers
