Handle key press with textbox

I am trying to only allow the user to input numeric characters in a textbox however when I run the program it says 

Unhandled exception at line 310, column 1 in Function code
0x800a138f - Microsoft JScript runtime error: Object expected

It highlights keypresshandler(event).

Heres my code:

jquery.js

function myFunction() {

if ((e.shiftKey || (e.keyCode < 48 || e.keyCode > 57)) && (e.keyCode < 96 || e.keyCode > 105)) {
    e.preventDefault();
}

}

Default.aspx

<asp:TextBox ID="SortOrderTextBox" runat="server" Height="10px" Text='<%# Eval("SortOrder") %>' Font-Size="Small"/>
                    <input type="text" onkeydown="myFunction()" />

This works for you:

<input type="text" onkeypress="myFunction()">

Change myFunction() to your function name, or whatever you're having it do.
