The example in this article describes how jquery implements a Taobao star rating function and is shared with you for your reference. The specific method is as follows:

The html part of the code is as follows:

<body>
  <div id="div">
    <ul>
      <li>☆</li>
      <li>☆</li>
      <li>☆</li>
      <li>☆</li>
      <li>☆</li>
    </ul>
  </div>
  <p id="p"></p>
  <p id="score"></p>
</body>

In the above code:

id="p"show real-time score

id="score" displays the final score

The javascript code is as follows:

<script type="text/javascript">
$(function () {
  //为所有的li标签绑定mouseout和mouseover事件。bind({事件名：function(){},事件名：function(){}})的方法绑定多个事件
  $("#div li").bind({
 mouseout:function () {
   $(this).css("color", "black").html("☆").prevAll().css("color", "black").html("☆")
 },
 mouseover: function () {
   $(this).css("color", "red").html("★").prevAll().css("color", "red").html("★")
 }
  });
  //=实时显示分数.【index】搜索匹配的元素，并返回相应元素的索引值，从0开始计数。
   $("#div li").mouseover(function () {
   $("#p").html(parseInt( $(this).index("#div li"))+1);
 });
  //鼠标按下时，确定分数。额，就不更改了，大局已定。
 $("#div li").mousedown(function () {
   $("#score").html(("你选择的分数是" + (parseInt($(this).index("#div li")) + 1)));
   $(this).css("color", "red").html("★").prevAll().css("color", "red").html("★")
   //全部li标签的绑定事件全部清除--unbind方法可以加参数清除特定的事件。不加全部清除
   $(this).unbind().prevAll().unbind().nextAll().unbind();
 });
  })
</script>
