try this javascript function:

function mask(textbox, e) {

      var charCode = (e.which) ? e.which : e.keyCode;
      if (charCode == 46 || charCode > 31&& (charCode < 48 || charCode > 57)) 
         {
            alert("Only Numbers Allowed");
            return false;
         }
     else
         {
             return true;
         }
       }

Call function like this in textbox,

JavaScript

onkeypress="return mask(this,event);"

Javascript Code:

function allnumeric(inputtxt)
{
var numbers = /^[0-9]+$/;
if(inputtxt.value.match(numbers))
{
alert('Your Registration number has accepted....');
document.form1.text1.focus();
return true;
}
else
{
alert('Please input numeric characters only');
document.form1.text1.focus();
return false;
}
}

HTML Code:

<input type='text' name='text1'/>

<input type="submit" name="submit" value="Submit" onclick="allnumericplusminus(document.form1.text1)" />
