| 10 | /* hoverIntent is similar to jQuery's built-in "hover" method except that
|
|---|
| 11 | * instead of firing the handlerIn function immediately, hoverIntent checks
|
|---|
| 12 | * to see if the user's mouse has slowed down (beneath the sensitivity
|
|---|
| 13 | * threshold) before firing the event. The handlerOut function is only
|
|---|
| 14 | * called after a matching handlerIn.
|
|---|
| 15 | *
|
|---|
| 16 | * // basic usage ... just like .hover()
|
|---|
| 17 | * .hoverIntent( handlerIn, handlerOut )
|
|---|
| 18 | * .hoverIntent( handlerInOut )
|
|---|
| 19 | *
|
|---|
| 20 | * // basic usage ... with event delegation!
|
|---|
| 21 | * .hoverIntent( handlerIn, handlerOut, selector )
|
|---|
| 22 | * .hoverIntent( handlerInOut, selector )
|
|---|
| 23 | *
|
|---|
| 24 | * // using a basic configuration object
|
|---|
| 25 | * .hoverIntent( config )
|
|---|
| 26 | *
|
|---|
| 27 | * @param handlerIn function OR configuration object
|
|---|
| 28 | * @param handlerOut function OR selector for delegation OR undefined
|
|---|
| 29 | * @param selector selector OR undefined
