This should get you started.

HTML Code:

<html>
<head>
<SCRIPT LANGUAGE="JavaScript"><!--
function doMatch()
{
 var re = new RegExp(document.demoMatch.regex.value);
 if(document.demoMatch.subject.value.match(re))
 {
  var dateParts = document.demoMatch.subject.value.split("/");
  if(dateParts[1] > 0 && dateParts[1] < 13 && dateParts[2] > 0 && dateParts[2] < 32)
  {
   document.getElementById("results").innerHTML = "Successful match";
   //return true;
   }
  else
  {
   document.getElementById("results").innerHTML = "No match";
   }
  }
 else
 {
  document.getElementById("results").innerHTML = "No match";
  }
 return false;
 }
// -->
</SCRIPT>
</head>
<body>
<FORM ID="demoMatch" NAME="demoMatch" METHOD=POST ACTION="#" onsubmit="return doMatch()">
<INPUT TYPE=hidden NAME="regex" VALUE="\d{4}/\d{2}/\d{2}" SIZE=50>
<P>Date(yyyy/mm/dd): <INPUT TYPE=TEXT NAME="subject"
   VALUE="" SIZE=50></P>
<P><INPUT TYPE=SUBMIT VALUE="Test Match"></P>
<div id="results"></div>
</FORM>
</body>
</html>
