You should implement this script on the page that contains the component in this case I will use a TabPanel

 <script type="text/javascript">
// this function get the TabPanel component
        var returnTheTab = function () {
            return Ext.getCmp('tpMain');
        }
    </script>

<ext:TabPanel ID="tpMain" runat="server" Region="Center" Margins="0 0 4 0" EnableTabScroll="true"
                IDMode="Static">
// .....

   </ext:TabPanel>

And this script on the page that you want retrieve the component 'TabPanel"

 <script type="text/javascript">

        var commandHandler = function (cmd) {
            if (cmd == "view") {
                var rootWindow = getRootWindow();
                var tab = rootWindow.returnTheTab();
              alert(tab);
            }
        };

// Get the parent Window
        function getRootWindow() {
            try {
                var wnd = this;
                while (wnd.parent.frameElement != null) {
                    wnd = wnd.parent;
                }
                return wnd.parent;
            }
            catch (e) {
            }
        }

    </script>
