onMouseIn( )

Adds an event handler that runs when the mouse pointer is moved onto the element.

Deprecation note: The $w parameter of event handlers is being deprecated. To get

a scoped selector for working with elements in repeater items, use the $w.at() function and pass it the context property of the event parameter: $item = $w.at(event.context). To learn more, see here.

You can also define an event handler using the Properties and Events panel.
