Hi Friend,

Try the following code:

<html>
<script>
function isNumber(){
if(/^-?\d+(\.\d+)?$/.test(form.number.value)){
return true;
}
alert("Invalid Number!Only 0-9 digits are allowed");
document.form.number.value="";
return false;
}
</script>
<form name="form">
Enter Number:<input type="text" name="number">
<input type="button" onclick="isNumber();" value="Check">
</form>
</html>

Thanks
