Well it is possible but it involves some scripting. My approach is to
create a div element that contains several absolute positioned
textboxes and spans. In HTML it looks like this;
<div style="position:relative;
width:200px;height:24px;background-color:white; border:solid blue 1px">
<input type="text"
style="position:absolute;left:2px;top:2px;height:2 0px;width:28px;border:solid
black 0px" maxLength="2"/>
<span
style="position:absolute;left:24px;top:2px;width:3 px;height:20px"
/</span>
<input type="text"
style="position:absolute;left:30px;top:2px;height: 20px;width:28px;border:solid
black 0px" maxLength="2"/>
</div>
This will give you the desired effect of a masked input. You can use a
pattern as an input parameter and parse it with regular expressions to
create your masked input. Use the onkeypress event on the textboxes to
validate the typed characters.
