__doPostBack( <%= control.UniqueID %>, ); best method?

I'm using the uinque ID of a control to identify it when calling __doPostBack() in javascript, after looking at a few posts on the subject. I was just wondering if this is still the best way to identify a control as some of the posts I looked at were quite old? Is there a new method of doing this when you are using things like master pages or user controls? Here's my code:

<asp:Content runat="server" ContentPlaceHolderID="ContentPlaceHolder1"

<script type="text/javascript"

function clickButton() {

alert("button will be clicked");

//this works, need to match this control id (delimited by '$'):

//__doPostBack('ctl00$ContentPlaceHolder1$LinkButton1','');

__doPostBack('<%= LinkButton1.UniqueID%>','');

}

</script

<asp:LinkButton ID="LinkButton1" runat="server"></asp:LinkButton>

<asp:Label ID="lblDebug" runat="server"></asp:Label>

<a href="javascript: clickButton();">Click LinkButton through javascript</a>

</asp:Content>

I'd be grateful for any feedback. Thanks
