22.1. Reset Buttons

HTML provides a way for you to create reset buttons. When a reset button is clicked, the form is reset to its default values. Unlike HTML, WML does not support the creation of reset buttons. However, you can use a way similar to what we described in the last section to create an anchor link that works like a reset button. Here is an example:

(resetButtonsEg1.wml)

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

<wml>
  <card id="card1" title="WML Form">
    <p>
      User name:<br/>
      <input name="myUserName"/><br/>

      Password:<br/>
      <input name="myPassword" type="password"/><br/><br/>

      <anchor>
        <go method="get" href="resetButtonsProc.asp">
          <postfield name="name" value="$(myUserName)"/>
          <postfield name="password" value="$(myPassword)"/>
        </go>
        Submit Data
      </anchor><br/>

      <anchor>
        <refresh>
          <setvar name="myUserName" value=""/>
          <setvar name="myPassword" value=""/>
        </refresh>
        Reset Form
      </anchor>
    </p>
  </card>
</wml>

The result of the above WML example in some mobile phone browsers is shown below:

Enter something in the input fields, like this:

If you click the "Reset Form" anchor link, the input fields will be reset to their default values.
