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;hei ght:24px;backgr ound-color:white; border:solid blue 1px">
<input type="text"
style="position :absolute;left: 2px;top:2px;hei ght:20px;width: 28px;border:sol id
black 0px" maxLength="2"/>
<span
style="position :absolute;left: 24px;top:2px;wi dth:3px;height: 20px"
/</span>
<input type="text"
style="position :absolute;left: 30px;top:2px;he ight:20px;width :28px;border:so lid
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.
