Can you please see in firebug console or firefox error console for any error, if appearing..

You are missing a semicolon in the following line

var charCode = (evt.which) ? evt.which : event.keyCode;

Its working fine for me after i put that

Hi Sandeep,

In which browser you checked.. for FF/Chrome, It worked fine for me.. with no change at all..

Well, for semicolon, I did search on google and found this.. http://mislav.uniqpath.com/2010/05/semicolons/
This might help those who need an answer for "Why Semicolon".. Though one line says that "There is no javascript interpreter which cant handle this'"

Hi Dean,
I played a litte with the script you posted and did not succeed to make it work for me, its like i can only receive non alfanumeric key-codes. As an alternative i did the fallowing:

i changed the " Max length" field to:
<tr height="35px"><td width="50%">Max Length:</td><td><input type="text" value="" name="maxLength" class="textBoxes" onkeyup="this.value = <portlet:namespace/>isNumberKey(this.value)"></td></tr>

where the portlet:namespace tag makes the script unique for the portlet

and i changed the script to:

function <portlet:namespace/>isNumberKey(evt){
if(isNaN(evt)){
return evt.substr(0,evt.length-1);
}
return evt;
}

Of course this is not bug-free because the user can still enter a value in the middle of the entered text but it shows the way you can manipulate your input on the fly
Hope this was useful
