This javascript is used to accept only numeric value in text box.
Coding :
<input type=”text “ onKeyPress=”return alfanumaricVal(event)” name=”amount” />
<script type=”text/javascript”>
function alfanumaricVal(e) {
var key;
var keychar;
if (window.event)
key = window.event.keyCode;
else if (e)
key = e.which;
else
return true;
keychar = String.fromCharCode(key);
keychar = keychar.toLowerCase();
// control keys
if ((key==null) || (key==0) || (key==8) || (key==9) || (key==13) || (key==27) )
return true;
// numbers
else if (((“0123456789″).indexOf(keychar) > -1))
return true;
