Obtrusive JavaScript Checker

Obtrusive JavaScript Checker is a tool to traverse through all elements in a web page, and when it finds a HTML element with inline events (which is bad, JavaScript should be unobtrusive), it highlights it with a red border. It also highlights javascript: links with a magenta border.

More information and a summary report

When you hover over an element with an inline event, it will show you more information about it:

The same goes for javascript: links:

At the bottom left corner of the window, you will be presented with a summary report of the number of javascript: links and inline events in the current web page, and each type of inline event summarized.

Availability
