让文本框里只能输入money

<script language="javascript" type="text/javascript">
        function onlyNum()
        {
            if(!(event.keyCode==46)&&!(event.keyCode==8)&&!(event.keyCode==37)&&!(event.keyCode==39)&&!(event.keyCode==190))
            if(!((event.keyCode>=48&&event.keyCode<=57)||(event.keyCode>=96&&event.keyCode<=105)))
            event.returnValue=false; //不让非数字显示
        }
    </script>

<asp:TextBox ID="TextBox1" runat="server" onkeydown="onlyNum();" style="ime-mode:Disabled"></asp:TextBox><br />
