我正面临悬停时显示div的问题。
当我将鼠标悬停在div元素A上时，div元素B会根据我的期望显示。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;
}<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.1.1/jquery.min.js" type="text/javascript"></script>
<p style="float: right;color: #17469e;" class="display_cal">12 october 2016</p>
<div class="calender_category_div" >
<ul>

我缺少什么？

有两个解决方案是通过 jquery或css
更新：将p标记更改为div
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;
}<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.1.1/jquery.min.js" type="text/javascript"></script>
<div style="float: right;color: #17469e;" class="display_cal">12 october 2016

您需要在calender_category_div内添加p。将p替换为div标记。然后在css的帮助下，它将起作用。无需撰写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>
<div style="float: right;color: #17469e;" class="display_cal">12 october 2016
<div class="calender_category_div" >
<ul>

这就是你需要的：
$(".calender_category_div").mouseleave(function(){
$(".calender_category_div").css("display", "none");
});
