WML <do> tag


WML Reference 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.

Syntax

<do type="type">
..task..
</do>

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.
