jquery鼠标悬停效果错误，鼠标悬停事件总是在鼠标悬停时触发几次

I have a simple gallery grid with a nested span that shows the title, which I want to slide up on mouse over, and hide on mouse out.

我有一个简单的图库网格，嵌套的跨度显示标题，我想在鼠标上滑动，然后隐藏在鼠标上。

Everything works fine, except whenever the mouse moves down to where the title is and/or hovers out of the tile from the bottom of the tile, then the hover effect repeats a few times uncontrollably.

一切都运行良好，除了当鼠标移动到标题所在的位置和/或从瓦片底部悬停在瓦片上时，悬停效果会不受控制地重复几次。

At first I thought it might be because the span is contained within the anchor which is the hover trigger, but moving it out didn't work either.

一开始我认为这可能是因为张成的空间包含在锚定中，锚定是悬停触发器，但把它移出去也不管用。

Any ideas ?

什么好主意吗?

标记:

<div class="gallery_container">
    <ul>
        <li><a href=""><img src="assets/img/artistisch.jpg" alt="aaa"/><span class="title">Category A</span></a></li>
        <li><a href=""><img src="assets/img/attraktiv.jpg" alt="bbb"/><span class="title">Category B</span></a></li>
        <li><a href=""><img src="assets/img/historisch.jpg" alt="ccc"/><span class="title">Category C</span></a></li>
        <li><a href=""><img src="assets/img/popart.jpg" alt="ddd"/><span class="title">Category D</span></a></li>
        <li><a href=""><img src="assets/img/portrait.jpg" alt="eee"/><span class="title">Category E</span></a></li>
        <li><a href=""><img src="assets/img/sketch.jpg" alt="fff"/><span class="title">Category F</span></a></li>
    </ul>
</div>

Here's the jquery

这是jquery

$(document).ready(function(){
    $('.gallery_container a').mouseover(function(){
        $(this).children('.title').animate({
            opacity: 100,
            bottom: 0
        },200);
    });

    $('.gallery_container a').mouseout(function(){
        $(this).children('.title').animate({
            opacity: 0,
            bottom: -30
        },200);
    });
});

3 个解决方案

#1

The problem here is that mouseover fires every time the mouse moves over the element or child elements. Try using the mouseenter and mouseleave events instead.

这里的问题是，每当鼠标移动元素或子元素时，鼠标悬停就会触发。尝试使用mouseenter和mouseleave事件代替。

#2

Try this.

试试这个。

$(document).ready(function() {
$('.gallery_container a').hover(function() {
    $(this).children('.title').stop().animate({
        opacity: 100,
        bottom: 0
    }, 200);
}, function() {
    $(this).children('.title').stop().animate({
        opacity: 0,
        bottom: -30
    }, 200);
}); 
});

So you may want to implement a really simple locking mechanism, as in:

所以你可能想要实现一个非常简单的锁定机制，如:

var fCurrentlyMoving = false;       
$('.gallery_container a').mouseover(function(){
    if (!fCurrentlyMoving) {
        fCurrentlyMoving = true;
        $(this).children('.title').animate({
            opacity: 100,
            bottom: 0
        },200, function() {
            fCurrentlyMoving = false;
        });
    }
});

it's not airtight race-condition-wise, but it doesn't need to be.

这不是无懈可击的比赛，但也不需要这样。
