WML <do> tag
 Complete WML Reference
The <do> tag can be used to activate a task when the user clicks on a
word/phrase on the screen.
A <do> tag can also be nested inside a <template> tag. The <do>
tag will then apply to all cards in the deck.

Examples
The example below uses a <do> tag inside a
<template> tag to add a "Back" link to each card:
<?xml version="1.0"?>
<!DOCTYPE wml PUBLIC "-//WAPFORUM//DTD WML 1.1//EN"
"http://www.wapforum.org/DTD/wml_1.1.xml">
<wml>
<template>
<do name="back" type="prev" label="Back">
<prev/>
</do>
</template>
<card id="card1" title="Card 1">
<p>
Hello World!
</p>
</card>
<card id="card2" title="Card 2">
<p>
From W3Schools!
</p>
</card>
</wml>
|
Note
If a single <card> contains multiple <do> elements of type="accept",
and these <do> elements are not named, WML might fail to compile and no page is
displayed.
This is caused because the default name when no name is specified is the element type, in
this case accept.
