Links

Links provide an alternative to using multiple event handlers to navigate between cards and decks. The main difference between links and <do> elements is that links are usually rendered in-line, whereas <do> elements are most often assigned to a labeled soft key at the bottom or top of the display. WML provides two ways to create a link, one a shorthand for the other. The <anchor> element is the most flexible way to create a link, and the <a> element is a shorter version with an implicit <go> element. Consider the following WML:

      <anchor title ="Staff">Staff Details
        <go href="http://gov.ns.ca/health/staff.cgi"/>
      </anchor>

This creates a link, which displays 'Staff Details' as the link anchor with a link to the 'staff' server-side script. The 'title' attribute may be used by a user agent to display additional link information, but this is not mandatory. A shorthand version of the preceding anchor code looks like the following:

      <a title ="Staff" href="http://gov.ns.ca/health/staff.cgi">
        Staff Details
      </a>

Overall, the shorthand <a> tag is preferred to the <anchor> because it can be more compactly coded for transmission to the wireless device.

The following example (see Figure 8) provides functionality similar to that shown in Figure 7, but uses links for navigation:

Links Including Embedded Image

The Link label references a soft key that, when pressed by a user, results in navigation to the target URL. Cursor keys are used to select different links. Note the use of an embedded image within the last <a> element.
