If you are already using javascript

1. A small piece of code that illustrates the problem.
2. The browser(s) and operating system(s) you're testing with.

<input size="30" maxlength="15" id="txtbox_license" onKeyDown="OnTextbox_Changed('vehicle', 'txtbox_license');" />

function OnTextbox_Changed(page, id){
	debugger
	var txtboxid = page+id;
	document.getElementById(id).value = document.getElementById(id).value.toUpperCase();		//convert the field to uppercase...
	switch(txtboxid){

//continues here.

}

<script>
function ShowText()
{
   var input = document.getElementById("input");
   var output = document.getElementById("output");
   var txt = input.value;
   if ( output.textContent != null )
      output.textContent = txt;
   else if ( output.innerText != null )
      output.innerText = txt;
}
</script>

<textarea id="input" style="width:90%;height:6em;" onkeyup="ShowText()"></textarea>
<div id="output"></div>
