    * { 
      padding: 0; 
      margin: 0; 
    } 
    .comment { 
      font-size: 40px; 
      color: teal; 
    } 
    .comment li { 
      float: left; 
    } 
    ul { 
      list-style: none; 
    } 
  </style> 
</head> 
<body> 
<ul class="comment"> 
  <li>☆</li> 
  <li>☆</li> 
  <li>☆</li> 
  <li>☆</li> 
  <li>☆</li> 
</ul> 
 
<script src="jquery-1.12.2.js"></script> 
<script> 
  $(function () { 
    var wjx_k = "☆"; 
    var wjx_s = "★"; 
    //prevAll获取元素前面的兄弟节点，nextAll获取元素后面的所有兄弟节点 
    //end 方法；返回上一层 
    //siblings 其它的兄弟节点 
    //绑定事件 
    $("li").on("mouseenter", function () { 
      $(this).html(wjx_s).prevAll().html(wjx_s).end().nextAll().html(wjx_k); 
    }).on("click", function () { 
      $(this).addClass("active").siblings().removeClass("active") 
    }); 
    $("ul").on("mouseleave", function () { 
      $("li").html(wjx_k);
