如何在将div2悬停并在mouseout上使div1褪色时显示div1？

Question

I want to display div1 on hovering div2 and disappear div1 only if mouse is not hovering both div1 and div2 .

I tried using the following CSS and jquery. But the div1 disappears immadiately after unhovering div2 and i am unable to access the content of div1.

  $(document).ready(function() { $('.about').hover( function() { $('.showsection').slideDown(800).addClass('show'); } , function() { $('.showsection').slideToggle(800); }); }); 

 .showsection{ display:none; } .show{ display:block; } 

 <script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script> <div class=about> <h1>About</h1> </div> <div class="showsection"> <h1>Title</h1> </div> 

Answer 1

The CSS :hover attribute will only control the element which it is assigned to, in your case presumable div1. So, you are going to have to use JavaScript.

With JavaScript attach a mouseenter and mouseleave event to div1. Inside those event listener functions, control what you want div2 to do.

That's basically how to do it.

Answer 2

This could be done by attaching mouseenter and mouseleave events to the elements you want to show/hide.

These are the requirements:

• Show showsection when mouse enters about . This can be done using mouseenter on about
• Hide showsection when mouse is not hovering over both showsection and about . This actually means checking two things: the mouse is not hovering showsection when it leaves about and the mouse is not hovering about when it leaves showsection . That means we have to attach mouseleave events to both showsection and about .

The below snippet should help.

 // JS $(document).ready(function() { // mouse enters .about $('.about').on('mouseenter', function() { $('.showsection').slideDown(800); }); // mouse leaves .about $('.about').on('mouseleave', function() { // if mouse is not hovering over .showsection hide it if (!$('.showsection').is(':hover')) { $('.showsection').slideToggle(800); } }); // mouse leaves .showsection $('.showsection').on('mouseleave', function() { // if mouse is not hovering over .about hide .showsection if (!$('.about').is(':hover')) { $('.showsection').slideToggle(800); } }); }); 

 /* CSS */ .showsection { display: none; background: #ddd; } h1 { margin: 0; } .about { background: #eee; }
