悬停时显示div的问题

问题描述 投票：0回答：3

我正面临着悬停时显示div的问题。

当我悬停在div元素A时，div元素B按照我的期望显示。但是当鼠标指针离开div元素A时，div元素B不会消失。

 $('.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;
      }

有两个解决方案是通过jquery或css

更新：将p标签更改为div

用于悬停效果的CSS：

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

它将为您提供toggle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();
    })

  })

更新的例子：

.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;
      }

你需要在calender_category_div中添加p。用p标签替换div。然后在css的帮助下它会起作用。不需要写jquery

.datespan{
  display: block;
}

.calender_category_div{
  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;
}
.display_cal:hover .calender_category_div{display:block}
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.1.1/jquery.min.js" type="text/javascript"></script>

这就是你需要的：

$(".calender_category_div").mouseleave(function(){
    $(".calender_category_div").css("display", "none");
});
