- Syntax:
- <onevent> ... </onevent>
The onevent tag serves as a container for code that you wish to be executed automatically when one of the four intrinsic events occurs. The onevent element is said to bind (associate) the tasks (code) to the event for the element.You must specify the intrinsic event by using the mandatory type attribute.
The four intrinsic events are:
| Event | Permitted Tags | Description |
| onenterbackward | card or template | Occurs when a prev navigates back into a card |
| onenterforward | card or template | Occurs when a go navigates into a card |
| onpick | option | Occurs when an item is selected or unselected by a user |
| ontimer | card or template | Occurs when the timer expires |
Note: The template element creates code that is inserted into all cards in a single deck.
Nested Tags: go noop prev refresh
