Hay.... you can try this one

JavaScript

function PhoneValidations(event) {
    var val;
    if (navigator.appName == "Microsoft Internet Explorer")
        val = window.event.keyCode;
    else
        val = event.which;
    if (val == 0)
        val = event.keyCode;

    if ((val >= 48 && val <= 57) || val == 45 || val == 37 || val == 39 || val == 9 || val == 40 || val == 41 || val == 32) {
        return true;
    }
    else if (val == 8)
        return true;
    else
        return false;
}

In Args you need to pass the e. (i.e. the event of page)

Solution 2

If you are using C# then try this.
This simple then javascript

XML

<asp:TextBox ID="txt_ID" runat="server" ></asp:TextBox>
//Add Extender
<asp:FilteredTextBoxExtender ID="txt_ID_FilteredTextBoxExtender" FilterType="Numbers" runat="server" Enabled="True" TargetControlID="txt_ID"> </asp:FilteredTextBoxExtender>
