asp checkbox to run javascript and serverside code

I have a page that has a input checkbox that will execute JavaScript code to show/hide a div. My requirements just changed to do server side code as well as show/hide the div. Is it possible to make a checkbox do both client JavaScript and server side code?

Checkbox:

<input type="checkbox" id="chkTemp"  />  

This is the javascript that runs when the checkbox is checked or unchecked.

    $('#chkTemp').click(function () {
      if ($('#chkTemp').is(":checked")) {                    
        $("#<%=(hdnTemp.ClientID)%>").val('true');
        $('#divTemp').show();
   }
   else {
        $('#divTemp').hide();
        $("#<%=(hdnTemp.ClientID)%>").val('false');
      }
    });

Since I need to do server side code I added

<asp:CheckBox ID="chkTemp2" runat="server" AutoPostBack="True" OnCheckedChanged="chkTemp2_CheckedChanged" />

Is it possible to have chkTemp2 execute javascript on the client and server side code at the same time?
