Here is simple Code for Numeric only and Email Validation using JavaScript
<input type="text" onkeypress="return
number(event);" />
<input type="text" onblur="checkEmailValidation(this);" />
<script type="text/javascript">
function
number(e) {
var
unicode = e.charCode ? e.charCode : e.keyCode;
if
(unicode != 8 && unicode != 9) {
if
(unicode < 48 || unicode > 57) return false;
}
// OR USE "^\d+$ " as RegExp
}
function
checkEmailValidation(obj) {
var
filter1 = /^.+@.+\..{2,3}$/;
if
(filter1.test(obj.value) != true) {
alert("invalid
Email");
}
}
</script>
