尝试以下简单的事情。

＆＃13; 
SELECT
    EMPNO,
    ENAME,
    CASE WHEN COUNT(DISTINCT JOB) > 1
         THEN 'yes' ELSE 'no' END AS job_changed,
    CASE WHEN COUNT(DISTINCT MGR) > 1
         THEN 'yes' ELSE 'no' END AS mgr_changed,
    CASE WHEN COUNT(DISTINCT HIREDATE) > 1
         THEN 'yes' ELSE 'no' END AS hire_date_changed,
    CASE WHEN COUNT(DISTINCT DEPTNO) > 1
         THEN 'yes' ELSE 'no' END AS dept_changed
FROM yourTable
GROUP BY
    EMPNO,
    ENAME
＆＃13; 
$('.panel-title a').click(function() {
  $('.panel').removeClass('bg');
  $('.panel-heading').removeClass('bg');
  $(this).closest('.panel').addClass('bg');
  $(this).closest('.panel-heading').addClass('bg');
});
＆＃13; 
body {
  padding: 50px;
}

.panel-default>.panel-heading {
  background: none;
}

.bg {
  background-color: cyan !important;
}
＆＃13;
＆＃13;

尝试这样的事情：

$(function(){
    $('.panel-title').click(function(){
    $(this).css('color', 'red');  // Here you can change color of its any parent element by using DOM traversing functions
  });
});

当手风琴打开时，您可以使用Accordion Events来检测。然后相应地更改它的背景颜色。

$('#accordion').on('shown.bs.collapse', function(){
    $('.panel').css("background-color", "#f5f5f5");
});

$(function(){
	$('.panel-title').click(function(){
  	$(".panel-heading").css('background','white');    
  	$(this).parent().css('background', 'gray'); 
 
    		if ( !$(this).find("a").hasClass( "collapsed" ) ) 
   			{ 
   					$(this).parent().css('background', 'white');   
  			 }
  
   
  });
});
＆＃13; 
body {padding: 50px;}
