WML <template> Tag
The <template> is used to apply <do> and <onevent> elements to all cards in a deck. This element defines a template for all the cards in a deck and the code in the <template> tag is added to each card in the deck.
You can override a <do> element of a template by defining another <do> element with the same name attribute value in a WML card.
Attributes:
The <template> element supports the following attributes:
| Attribute | Value | Description |
|---|---|---|
| onenterbackward | URL | Occurs when the user navigates into a card using a "prev" task |
| onenterforward | URL | Occurs when the user navigates into a card using a "go" task |
| ontimer | URL | Occurs when the "timer" expires |
| class | class data | Sets a class name for the element. |
| id | element ID | A unique ID for the element. |
Example:
Following is the example showing usage of this element:
