Mouse movement / mouseover and JavaScript evaluation in watir

I have a JavaScript-heavy Rails app which I am testing in watir. I have two specific testing requirements:

• I need to be able to simulate moving the mouse to a specific area of the screen (or at least triggering the onmouseover event for a div)
• Evaluating a snippet of JavaScript once the above has happened to see if a flag is set correctly

I haven't been able to figure开发者_StackOverflow out how to do this in watir. Any ideas on how to do this?

For the first question:

browser.div(:id, "some-id").fire_event "onmouseover"

I have no idea how to solve the second question. You could ask at watir-general.

You can look at the following page for mouse controls:
