First of all, I'm assuming this is too complex for CSS3, but if there's a solution in there somewhere, I'd love to go with that instead.
The HTML is pretty straightforward.
<div class="parent">
<div class="child">
Text Block 1
</div>
</div>
<div class="parent">
<div class="child">
Text Block 2
</div>
</div>
The child div is set to display:none; by default, but then changes to display:block; when the mouse is hovered over the parent div. The problem is that this markup appears in several places on my site, and I only want the child to be displayed if the mouse is over it's parent, and not if the mouse is over any of the other parents (they all have the same class name and no IDs).
I've tried using $(this) and .children() to no avail.
$('.parent').hover(function(){
$(this).children('.child').css("display","block");
}, function() {
$(this).children('.child').css("display","none");
});
This question is related to
jquery
css
jquery-selectors
parent
Use toggleClass().
$('.parent').hover(function(){
$(this).find('.child').toggleClass('color')
});
where color is the class. You can style the class as you like to achieve the behavior you want. The example demonstrates how class is added and removed upon mouse in and out.
No need to use the JavaScript or jquery, CSS is enough:
.child{ display:none; }
.parent:hover .child{ display:block; }
Stephen's answer is correct but here's my adaptation of his answer:
<div class="parent">
<p> parent 1 </p>
<div class="child">
Text Block 1
</div>
</div>
<div class="parent">
<p> parent 2 </p>
<div class="child">
Text Block 2
</div>
</div>
.parent { width: 100px; min-height: 100px; color: red; }
.child { width: 50px; min-height: 20px; color: blue; display: none; }
.parent:hover .child, .parent.hover .child { display: block; }
//this is only necessary for IE and should be in a conditional comment
jQuery('.parent').hover(function () {
jQuery(this).addClass('hover');
}, function () {
jQuery(this).removeClass('hover');
});
You can see this example working over at jsFiddle.
Not sure if there's terrible reasons to do this or not, but it seems to work with me on the latest version of Chrome/Firefox without any visible performance problems with quite a lot of elements on the page.
*:not(:hover)>.parent-hover-show{
display:none;
}
But this way, all you need is to apply parent-hover-show to an element and the rest is taken care of, and you can keep whatever default display type you want without it always being "block" or making multiple classes for each type.
.parent:hover > .child {
/*do anything with this child*/
}
To change it from css you dont even need to set the child class
.parent > div:nth-child(1) { display:none; }
.parent:hover > div:nth-child(1) { display: block; }
I have what i think is a better solution, since it is scalable to more levels, as many as wanted, not only two or three.
I use borders, but it can also be done with whateever style wanted, like background-color.
With the border, the idea is to:

And here is the code:
<!DOCTYPE html>
<html>
<head>
<meta charset=utf-8 />
<title>Hierarchie Borders MarkUp</title>
<style>
.parent { display: block; position: relative; z-index: 0;
height: auto; width: auto; padding: 25px;
}
.parent-bg { display: block; height: 100%; width: 100%;
position: absolute; top: 0px; left: 0px;
border: 1px solid white; z-index: 0;
}
.parent-bg:hover { border: 1px solid red; }
.child { display: block; position: relative; z-index: 1;
height: auto; width: auto; padding: 25px;
}
.child-bg { display: block; height: 100%; width: 100%;
position: absolute; top: 0px; left: 0px;
border: 1px solid white; z-index: 0;
}
.child-bg:hover { border: 1px solid red; }
.grandson { display: block; position: relative; z-index: 2;
height: auto; width: auto; padding: 25px;
}
.grandson-bg { display: block; height: 100%; width: 100%;
position: absolute; top: 0px; left: 0px;
border: 1px solid white; z-index: 0;
}
.grandson-bg:hover { border: 1px solid red; }
</style>
</head>
<body>
<div class="parent">
Parent
<div class="child">
Child
<div class="grandson">

<div class="grandson-bg"></div>
</div>
<div class="child-bg"></div>
</div>
<div class="parent-bg"></div>
</div>

If you're using Twitter Bootstrap styling and base JS for a drop down menu:
.child{ display:none; }
.parent:hover .child{ display:block; }
This is the missing piece to create sticky-dropdowns (that aren't annoying)
