Visual Event Javascript Bookmarklet

Posted · Category: License Free, Tools

When working with events in Javascript, it is often easy to loose track of what events are subscribed where. This is particularly true if you are using a large number of events, which is typical in a modern interface employing progressive enhancement. If things go wrong, it can be difficult to trace down.

It is due to this Allan Jardine has put together a Javascript bookmarklet called Visual Event which visually shows the elements on a page that have events subscribed to them, what those events are and the function that the event would run when triggered. This is primarily intended to assist debugging, but it can also be very interesting and informative to see the subscribed events on other pages.

    Very cool! I’ll be using this as we launch our new site. Very handy to have!

  • Nice thingy.
    Always have problems guessing what kind of events are attached – something not visible in FireBug.
    Lets if/when ExtJs will be added to the list of supported frameworks.
