javascript - 悬停时显示 div 的问题

Question

我遇到了在悬停时显示 div 的问题。

当我将鼠标悬停在 div 元素 A 上时，div 元素 B 会按照我的预期显示.但是当鼠标指针离开div元素A时，div元素B并没有消失。

 $('.display_cal').hover(function () {
          $('.calender_category_div').css("display" , "block");
      });

	 .datespan{
          display: block;
      }

      .calender_category_div{

          position: absolute;
          top: 40%;
          left: 50%;
          z-index: 1050;
          background: #FFFFFF;
          padding: 10px 20px;
          display: none;
      }

      .calender_category_div ul{
          padding: 0;
      }

      .calender_category_div ul a {
          color: #428bca;
          text-decoration: none;

      }

      .calender_category_div ul a:hover {
          color: #428bca;
      }

      .calender_category_div ul {
          color: #428bca;
          list-style-type: none;
      }

            </div>

我缺少什么？

Answer 1

有两个解决方案是通过 jquery 或 css

更新:将p标签改为div

悬停效果的CSS:

.display_cal:hover  >.calender_category_div{
  display:block;
  }

它会为您提供切换效果。

或使用 jquery

$(document).ready(function (){
  $('.display_cal').mouseover(function(){
    $('.calender_category_div').show();
    })
  $('.display_cal').mouseleave(function(){
    $('.calender_category_div').hide();
    })

  })

更新示例:

.datespan{
          display: block;
      }

      .calender_category_div{
         position: absolute;
          top:5px;
          right:-10;
        
          z-index: 1050;
          background: transparent;
          padding: 10px 20px;
          display: none;
      }
.display_cal:hover  >.calender_category_div{
  display:block;
  }

      .calender_category_div ul{
          padding: 0;
      }

      .calender_category_div ul a {
          color: #428bca;
          text-decoration: none;

      }

      .calender_category_div ul a:hover {
          color: #428bca;
      }

      .calender_category_div ul {
          color: #428bca;
          list-style-type: none;
      }
