Code:

// hide all elements except a few
//hideAllExcept('#ctl00_PlaceHolderMain_gvSummary')
function hideAllExcept(selectrId) {
//$('body > :not(#ctl00_PlaceHolderMain_gvSummary)').hide();
    //$('[id*=gvSummary]').appendTo('body');
   
    $('body > :not(' + selectrId + ')').hide();
    $('[id*=' + selectrId + ']').show(); //or  appendTo('body');
   
}
