WML ontimer Event
The ontimer event is used to trigger an event after a given time period. Let's say you want to display a message after 5 seconds of loading a card then you can use this event to do so.
Here is the syntax to define an event handler for ontimer event:
<onevent type="ontimer">
A task to be performed.
</onevent>
<timer value="50"/>
|
Here it means that a task will be performed after 5 seconds.
Following is the example showing usage of ontimer event alongwith <onevent> element.
<?xml version="1.0"?>

<onevent type="ontimer">
<go href="#welcome"/>
</onevent>
<timer value="50"/>
<p>
<a href="#welcome">Enter</a>
</p>
</card>
<card id="welcome" title="Welcome">
<p>
Welcome to the main screen.
