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:
 Sony
Ericsson T610
|
 Sony
Ericsson T68i
|
 Nokia

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