11.1. Going to a Card in Another Deck

Preferences - Do not show ads

The offset of a URL informs the WAP browser which card of a certain deck should be shown. An offset begins with the # character. A card in a deck is identified by the id attribute value of the <card> tag. The offset of a URL should be the ID of the target card.

The following WML example illustrates how to go to a card in another deck. The WML document below contains the cards of the first deck.

The following WML document contains the cards of the second deck:

<?xml version="1.0"?>
<!DOCTYPE wml PUBLIC "-//WAPFORUM//DTD WML 1.3//EN" "http://www.wapforum.org/DTD/wml13.dtd">

<wml>
  <card id="tutorial_ch1" title="WML Tutorial Ch1">
    <p>
      <em>Chapter 1: WML Introduction</em><br/><br/>
      ...
    </p>
  </card>

  <card id="tutorial_ch2" title="WML Tutorial Ch2">

      <em>Chapter 2: WML Deck and Card</em><br/><br/>

  </card>

  <card id="tutorial_ch3" title="WML Tutorial Ch3">

  <card id="tutorial_ch4" title="WML Tutorial Ch4">

  </card>
</wml>

If you view the first WML document in a WAP browser, you should see something like this:

If you select an anchor link in the above card, the WAP browser will show a card of another deck. For example, if you select the "Chapter 2: WML Deck and Card" anchor link, the WAP browser will display the card of which the ID is "tutorial_ch2" in the linksEg2.wml file, and you will see something like this:

If an anchor link's URL does not have the offset, WAP browsers will display the first card of the deck. For example, let's say you create an anchor link using the WML markup below:

<anchor>
  <go href="linksEg2.wml"/>
  Chapter 1: WML Introduction
</anchor>

If you select the above anchor link, the WAP browser will display the first card contained in the linksEg2.wml file, that is the card with "tutorial_ch1" as its ID.
