Losing hover when animating with jQuery (without moving mouse)
I have this row of thumbnails that I am animating with jQuery.
Each of these thumbnails has a hover and active class.
They work fine but when I animate the list, the new thumbnail under the mousecursor does not apply the hover? I have to move the mouse a little bit after each click?
It's kinda difficult to exaplain.. I have made a fiddle here: http://jsfiddle.net/nZGYA/
When you start clicking after thumb 3 without moving the mouse you see what I mean...
It works fine in FireFox, NOT Safari, Chrome, IE etc.
Is there something I can do about this?
For reference here is my code:
<style type="text/css">
.container { position: relative; overflow: hidden; width: 140px; height: 460px; float: left; margin-right: 100px; background: silver; }
ul { position: absolute; top: 10; list-style: none; margin: 10px; padding: 0; }
li { margin-bottom: 10px; width: 120px; height: 80px; background: gray; }
#list-2 li a { display: block; width: 120px; height: 80px; outline: none; }
#list-2 li a:hover { background: teal; }
#list-2 li a.active { background: navy; }
</style>
$(document).ready(function() {
var idx_2 = 0;
$('#list-2 li a')
.click(function() {
$('#list-2 > li a').removeClass('active');
$(this).addClass('active');
var id = $('#list-2 li a.active').data('index') - 2;
idy = Math.max(0, id * 90);
$(this).parent().parent().animate({ 'top' : -idy + 'px' });
return false;
})
.each(function() {
$(this).data('index', idx_2);
++idx_2;
});
});
<div class="container">
<ul id="list-2">
<li><a class="active" href="#"></a></li>
<li><a href="#"></a></li><li><a href="#"></a></li><li><a href="#"></a></li><li><a href="#"></a></li>
<li><a href="#"></a></li><li><a href="#"></a></li><li><a href="#"></a></li><li><a href="#"></a></li>
<li><a href="#"></a></li><li><a href="#"></a></li><li><a href="#"></a></li><li><a href="#"></a></li>
<li><a href="#"></a></li><li><a href="#"></a></li><li><a href="#"></a></li><li><a href="#"></a></li>
<li><a href="#"></a></li><li><a href="#"></a></li><li><a href="#"></a></li><li><a href="#"></a></li>
<li><a href="#"></a></li><li><a href="#"></a></li><li><a href="#"></a></li><li><a href="#"></a></li>
</ul>
</div>
I only worked on the top list but I think I got it all working. let me know if it is what you are looking for.
Here is the fiddler
var idx = 0;
$('#list-1 li').hover(function() {
$(this).addClass('hover');
}, function() {
$(this).removeClass('hover');
}).click
(function() {
var currentindex = $('.active').index();
var selectedindex = $(this).index();
var nexthoverindex = selectedindex + (selectedindex - currentindex);
//counter for starting on index 1
if(currentindex === 1 && selectedindex > 2){
nexthoverindex = nexthoverindex - 1;
}
//counter for starting on index 0
if(currentindex === 0 && selectedindex > 2){
nexthoverindex = nexthoverindex - 2;
}
//make sure the selection never goes below 0
if(nexthoverindex < 0){
nexthoverindex = 0;
}
$('#list-1 > li').removeClass('active');
$(this).addClass('active');
var id = $('#list-1 li.active').data('index') - 2; // take scroll param and subtract 2 to keep selected image in the middle
idy = Math.max(0, id * 90);
$(this).parent().animate({
'top': -idy + 'px'
},200, function(){
$('.hover').removeClass('hover');
if(currentindex > 2 || selectedindex > 2){
$('#list-1 > li').eq(nexthoverindex).addClass('hover');
}
});
return false;
}).css('cursor', 'pointer').each(function() {
$(this).data('index', idx);
++idx;
});
I've got a solution that works in Chrome and IE (haven't tested in Safari). Basically I trigger the mouseover() event of the element under the mouse in the animate() callback event if the thumbnails have moved. The solution is only implemented for list-1.
// list 1
var idx = 0;
$('#list-1 li').hover(function() {
$(this).addClass('hover');
}, function() {
$(this).removeClass('hover');
}).click(function() {
$('#list-1 > li').removeClass('active');
var $active = $(this);
$active.addClass('active');
var id = $('#list-1 li.active').data('index') - 2; // take scroll param and subtract 2 to keep selected image in the middle
var moveAmount = 90;
idy = Math.max(0, id * moveAmount);
var oldPos = $active.parent().position().top;
$active.parent().animate({
'top': -idy + 'px'
}, function(){
var newPos = $(this).position().top;
// Check if we moved
if(oldPos - newPos != 0)
{
var movement = (oldPos - newPos) / moveAmount;
$($(this).children()[$active.index() + movement])
.trigger("mouseover");
}
});
return false;
}).css('cursor', 'pointer').each(function() {
$(this).data('index', idx);
++idx;
});
And here's the link to my fork in jsfiddle if you wan't to test it out over there - http://jsfiddle.net/jimmysv/3tzAt/15/
Hover binds mouseEnter() and mouseLeave() to the object. I think you'll have better luck with mouseOver() in this case, though I haven't tried it.
What is the difference between the mouseover and mouseenter events?
