Can you stop ASP.NET from changing IDs so that it can be used in jQuery

I have this label control in my web page using

< asp:Label ID="Label1" runat="server" Text="test">< /asp:Label >
And when the page rendered the id of the control changes to something like this

< span id="ctl00_ContentPlaceHolder1_Label1">test< /span >
How can I stop from changing IDs in order to perform a jQuery operation like this
