jquery 在鼠标悬停时滑入和滑出，具有缓动效果

Question

我正在寻找一个 jquery 脚本来实现隐藏/显示 div 的轻松进出效果，该效果是在 此网站。

这是我的 mouseover() 脚本：

$("#box0").mouseover(function () {
    $("#lSection2").fadeIn(100);    
    $("#boxContent0").fadeIn(100);
});   
$('#boxContent0').mouseout(function() {
    $("#boxContent0").fadeOut(100);     
    $("#lSection2").fadeOut(100);
});

CSS:

.AdBox {
    width: 300px;
    height: 180px;
    border: 6px solid #fff;
    -webkit-border-radius: 5px;
    -moz-border-radius: 5px;
    -o-border-radius: 5px;
    border-radius: 5px;
    float: left;
    margin-right: 10px;
    margin-left: 10px;
}

.AdBoxl {
    width: 300px;
    height: 180px;
    border: 6px solid #666;
    float: right;
}

.boxContent div {
    width: 180px;
    padding: 10px;
    font-family: Arial, Helvetica, sans-serif;
    font-weight: bold;
    font-size: 16px;
    height: 120px;
    border: 4px solid #fff;
    float: left;
    margin-right: 10px;
    margin-left: 20px;
    -webkit-border-radius: 3px;
    -moz-border-radius: 3px;
    -o-border-radius: 3px;
    border-radius: 3px;
    background-color: #80634A;
}

#lSection2 {
    height: 120px;
    width: 100%;
    position: relative;
    top: 10px;
    padding-left: auto;
    padding-right: auto;
}

.boxContent {
    width: 970px;
    background-image: url(../images/gridtile.png);
    height: 150px;
    padding-top: 15px;
}

您不需要特殊的插件来执行 jQuery 缓动。您可以像这样简单地将您选择的缓动函数包含到您的 jQuery 中。 （我选择“easeOutCubic”作为应用于所有动画的示例，但每个动画也可以有自己的动画。）

$.easing.easeOutCubic = function (x, t, b, c, d) {
    return c*((t=t/d-1)*t*t + 1) + b;
}

$("#box0").mouseover(function () {
    $("#lSection2").fadeIn(100, 'easeOutCubic');    
    $("#boxContent0").fadeIn(100, 'easeOutCubic');
});   
$('#boxContent0').mouseout(function() {
    $("#boxContent0").fadeOut(100, 'easeOutCubic');     
    $("#lSection2").fadeOut(100, 'easeOutCubic');
});

这些是对应的函数。只需选择并使用与您的项目相关的功能...

旁注：

您的代码正在使用 mouseover 和 mouseout 这可能会导致不稳定的行为这些事件是如何触发的。当鼠标悬停在该项目上时，mouseover 将触发多次。 mouseenter 和 mouseleave 更加稳定。 您甚至可以使用 .hover() 它会自动组合 .mouseenter() 和 .mouseleave() 合并到一个方法中。

并且您的动画持续时间 100 只是一秒的十分之一。这太快了，无法看到任何缓解效果。
