Qt 4.8.4 QtWebkit doesn't load Javascript

adrian

Hello,

I'm using qtwebkit to load webpage inside my app. The HTML is loaded well but the Javascript is never loaded.

Do you know what could be happen ?

Thanks a lot.

please make sure:
@
myWebView->settings()->setAttribute(QWebSettings::JavascriptEnabled, true);
@

If it still doesn't work subclass QWebPage and reimplement javaScriptConsoleMessage():
@
void MyWebPage::javaScriptConsoleMessage ( const QString & message, int lineNumber, const QString & sourceID )
{
qDebug() << "CONSOLE (" << sourceId << ":" << lineNumber << "):" << message;
}
@
Then you can see any javascript error which prevent your script to be loaded.

Thank you for your response.

I've ensure that I've enabled the javascript attribute.
When I execute "evaluateJavascript('console.log('test')'), the javascript engine does not return any result to invoke MyWebPage::javaScriptConsoleMessage function.
I think the problem is into the WebKit Javascript engine, I am enabling the javascript attribute but it is not enabling it.
I have tried to test a simple web page executing an alert('') function, and if I execute into a desktop envioment (linux X86) it works correctly. If I build the same code into a ARM enviroment, it not works. Any idea?

Thank you.

Hello,

  I have tried to execute this function:

QVariant name = ui->myBrowser->page()->mainFrame()->evaluateJavaScript("function abc(){alert('This page has finished loading!');return 'he'} abc();");

qDebug() << "NAME: " << name.toString();

The result of NAME can be garbage of the buffer?

  NAME:  "-1.45215999014136e-58"       NAME:  "-1.45215999014147e-58"       NAME:  "-1.45215999014158e-58"       NAME:  "-1.45215999014169e-58"       NAME:  "-1.45215999014179e-58"       NAME:  "-1.4521599901419e-58"       NAME:  "-1.45215999014201e-58"       NAME:  "-1.45215999014212e-58"       NAME:  "-1.45215999014222e-58"       NAME:  "-1.45215999014233e-58"       NAME:  "-1.45215999014244e-58"       NAME:  "-1.45215999014255e-58"       NAME:  "-1.45215999014265e-58"

I am using QT 4.8.4 version, and with older versions I had not problems.

Thanks.
