Profile Javascript

[mlucool]

Hi,

I have an application which uses a QWebView to render a QWebPage, but does not use QtQuick. This webpage is mostly javascript and I need to profile it. What are the recommended tools for doing this? I have tried to use the QML profiler (with Qt 5.3.1), but since there is no QML, it does not comes up with no stats. To get this to work, I had to add some QML code just to have it open: "QQuickView *qmlView = new QQuickView" but that code is otherwise unused.

In my javascript file I have added console.profile/profileEnd to the required function. Is there a way to redirect this console or connect it to some profiler? The application uses Qt 5.2 but can be upgraded if needed.

Thanks,
Marc

You should be able to use any Javascript profiler available. Qt does not have any support for profiling Javascript code. It only has a regular WebKit's Web inspector.
