在一个元素上更改另一个元素

Question

I've got following piece of html code:

<div class="header-menu hide-for-small">
    <ul id="primary-menu" class="subtext">
        <li id="menu-item-993"><a>X</a></li>
        <li id="menu-item-994"><a>Y</a></li>
        <li id="menu-item-995"><a>Z</a></li>
    </ul>
</div>
<div class="post-filter">..</div>

Plus the css:

.post-filter {
    display: none!important;
}

What I'm trying to achieve is to show .post-filter div only when hovered #menu-item-993 . So im doing:

#menu-item-993:hover .post-filter {
    display:block!important;
}

But this just don't work. I've tried to put + or ~ between ..:hover and .post-filter - without success. What Im doing wrong?

Answer 1

Here's a mouseover (mouseenter) function:

$("#menu-item-993").mouseenter(function () {
    $(".post-filter").show();
}).mouseleave(function () {
    $(".post-filter").hide();
});

If this doesn't override the !important try this (assuming no other dependencies in JS on post-filter class):

$("#menu-item-993").mouseenter(function () {
    $("div.header-menu + div").removeClass("post-filter");
}).mouseleave(function () {
    $("div.header-menu + div").addClass("post-filter");
});

Answer 2

Code

 $("#menu-item993").mouseenter(function () {
     $(".post-filter").addClass('dispaly')
 }).mouseleave(function () {
     $(".post-filter").removeClass('dispaly');

});

Css

   .display
    {
     display:block;
   }

Answer 3

Add and remove the class of styling with Javascript. And you don't need !important on the initial css.

$("#menu-item-993").mouseenter(function(){
    $(".post-filter").addClass("showit");
}).mouseleave(function(){
    $(".post-filter").removeClass("showit");
});

Here is a way using hover function and the show / hide functions

 $('#menu-item-993').hover(function(){ $('.post-filter').show(); },function(){ $('.post-filter').hide(); }); 

 <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> <div class="header-menu hide-for-small"> <ul id="primary-menu" class="subtext"> <li id="menu-item-993"><a>X</a> </li> <li id="menu-item-994"><a>Y</a> </li> <li id="menu-item-995"><a>Z</a> </li> </ul> </div> <div class="post-filter" style="display:none">..</div> 

Answer 5

Try this toggleClass option

 $("body").on("mouseover mouseout", '#menu-item-993', function(){ $('.post-filter').toggleClass("show hide"); }); 

 .post-filter { display: none!important; } .show { display: block!important; } .hide { display: hide!important; } 

 <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> <div class="header-menu hide-for-small"> <ul id="primary-menu" class="subtext"> <li id="menu-item-993"><a>X</a> </li> <li id="menu-item-994"><a>Y</a> </li> <li id="menu-item-995"><a>Z</a> </li> </ul> </div> <div class="post-filter">text</div> 

Answer 6

You can use hover function & add css to show and hide it

$("#menu-item-993").hover(function(){
  $(".post-filter").css('display','block')
},function(){
  $(".post-filter").css('display','none')
})

<a id="thumbnail" href="#"><img src="http://dummyimage.com/150x150/0066ff/fff"></a>
<div id="title">filename.jpg</div>



#thumbnail {
display: block;
width: 150px;
height: 150px;
}

#thumbnail:hover + #title {
display: block;
}

#title { 
display: none;
color: #ffffff;
background-color: #000000;
text-align: center;
width: 130px;
