Disable the edit area

Hi,
I have the Edit area like

<asp:Label ID="Label1"
        Text="Test"
        width="500px"
        Font-Names="Times New Roman"
        Font-Size="15pt"
        Font-Bold="true"
        ForeColor="DarkBlue"
        runat="server" />
    <script type="text/javascript" src="<%= ResolveUrl("~/content/javascript/ckeditor/ckeditor.js") %>"></script>
    <script type="text/javascript" src="<%= ResolveUrl("~/content/javascript/ckeditor/adapters/jquery.js") %>"></script>
    <textarea id="ta1" name="MyEA" runat="server" ></textarea>
    <script type="text/javascript">
        CKEDITOR.replace('<%=ta1.ClientID.Replace("_","$") %>', { toolbar: 'Mybar' });
        $("#ta1").attr("disabled", "disabled");
    </script>    ...

using CK editor. how to disable the Edit of the text and also the relevant buttons there, as the above codes are not working as expected?
