How do I hide text when doing a mouse rollover?

So the infuriating answer to this is that even though Cap uses JS - a wickedly powerful DOM manipulation language - it often effectively hobbles it for its own overhead, leaving you to root around trying to hack it. That's the knee-jerk reaction I seem to have, anyway. In this case the reason probably has more to do with mobile support - do or do not, there is no rollover in mobile, and Cap is probably trying to prevent you from doing something that won't be supported if your training has to work on phones/tablets/etc. But lets hack at it anyway and see what we get!

I created a button ("hideTextButton") and a text caption ("Text_Caption_1") on the first slide of an empty project to see if I could shoehorn Cap into respecting a mouseover. On the onEnter of the master slide I added a script to grab a reference to the button and caption DOMs, added a native mouseenter event to the button, and logged both the hooks to the DOM and (hopefully) the event firing to the console to confirm everything's existence. See below:

Previewing the project in HTML5 in Browser this was the result:

We can actually get a mouseover to fire! In this case I hovered over that button three times before taking the screencap. But something in Cap almost immediately reset the CSS state - I watched the CSS display value flicker to "none" and blink right back to "block" on each hover.

The next trick would be hunting down what function/functionality was switching the state back to display or use something other than a text caption object. Something that isn't subject to Cap resetting its state. Maybe a smart object? Dunno, you'd have to tinker with it a bit and see which thing you had more control over and that Cap didn't reset. I also tried setting the visibility to "hidden" instead of display none and had similarly unsatisfying results. But if you did get it working you could potentially cause frustrating or impassible functionality by tying information or progression to an event that isn't supported in mobile environments...

You're going to run into problems trying to use Advanced Actions for this because they require you to use events to trigger them, and Captivate only really has one object that can trigger an action on mouse over.  That's the Rollover Slidelet object found under the Objects button.  However, although it has a rollover event, it has no rollout event that you could use to undo whatever the rollover event did.

I suggest you are probably better off just doing this the easy way using a Rollover Caption object.  No advanced actions required then to show or hide text in the caption.
