How do I get Palm's WebOS browser to default to numeric input?

Question

The following CSS worked fine in my Windows mobile phone, but my Pre won't default to numeric inputs.

input.numeric {
 -wap-input-format:"*n";
}

How do I get the Pre (and presumably other newer mobile browsers?) to default to numeric inputs?

Answer 1

Just a guess, but the new number value for the type attribute introduced in HTML5 does work on the Mobile Safari:

<input type="number" min="0" max="10" step="2" value="6" />
