我有点难以用自动高度解决这个CSS过渡问题,并想知道其他人是否会有任何线索和建议。提前谢谢。
使用Javascript:
$(document).ready(function(){
$(".button").click(function(){
$(".test").toggleClass("collapse");
});
});
CSS:
.test.collapse ul {
height: auto;
CSS:
.test.collapse ul {
height: 500px;
是否有人知道如何使示例#1工作?
谢谢!

感谢大家的反馈。这是我使用的最终解决方案,可以实现响应和平滑的切换:

$(document).ready(function(){
$(".button").click(function(){
$(".collapse-list").toggleClass("collapse");
});
});

无法使用高度转换:auto。 最大高度的技巧是一个非常好的解决方案,但有一些不便,特别是如果最大高度远高于实际高度,则会出现奇怪的延迟。
以下是我使用的技巧:http://jsfiddle.net/g56jwux4/2/ 基本上它是两个相反方向翻译的叠瓦式DIV。看看jsfiddle的代码,因为我的英语不够清楚。
HTML部分:
<body>
<p>Technicaly this dropdown menu looks like a simple height transition.</p>
<p>But this pure css code also works this a variable number of choices in menu, working around the "height:auto" not taken into account by css transitions.</p>
<input type="checkbox" id="menuOpen"></input>
<label id="bouton" for="menuOpen"><span>Click on me !</span>
<div id="menu">
<div id="masque">
<div class="choix" id="choix1">Choix 1</div>
<div class="choix" id="choix2">Choix 2</div>
<div class="choix" id="choix3">Choix 3 très très long pour voir la taille finale du menu</div>
<div class="choix" id="choix4">Choix 4</div>
<div class="choix" id="choix5">Choix 5</div>
<div class="choix" id="choix6">Choix 6</div>
</div>
</div>
</label>
</body>
CSS部分:
body {
font-family: sans-serif;
}
#menuOpen {
display: none;
}
#bouton {
position: absolute;
left: 100px;
top: 100px;
width: 200px;
height: 30px;
background-color: lightgray;
cursor: pointer;
}
#bouton > span {
color: black;
padding: 6px;
line-height: 30px;
}
#menu {
position: absolute;
top: 100%;
overflow: hidden;
min-width: 100%;
transition: transform 0.3s linear 0s, visibility 0.3s linear 0s;
transform: translateY(-100%);
visibility: hidden;
color: white;
}
#menuOpen:checked + #bouton > #menu {
transform: translateY(0%);
visibility: visible;
transition: transform 0.3s linear 0s, visibility 0s linear 0s;
}
#menuOpen:checked + #bouton > #menu > #masque {
transform: translateY(0%);
}
#masque {
position: relative;
background-color: gray;
transform: translateY(100%);
transition: transform 0.3s linear 0s;
}
.choix {
white-space: nowrap;
padding: 3px 6px;
}
.choix:hover {
background-color: darkgray;
}

尝试以下内容。通过LI和高度,以便不会切断任何东西。根据需要进行调整。
$(document).ready(function(){
$(".button").click(function(){
$(".test").toggleClass("expand", 5000);
});
});
&#13;
.test ul {
width:50%;
overflow:hidden;
height:auto;
-webkit-transition-duration: 0.8s;
-moz-transition-duration: 0.8s;
-o-transition-duration: 0.8s;
transition-duration: 0.8s;
}
.test li {
float:left;
width:100px;
}
.test li:not(:nth-of-type(-n+10)) {
width:100px;
display: none;
}
.test.collapse ul {
width:50%;
height: 500px;
-webkit-transition-duration: 0.8s;
-moz-transition-duration: 0.8s;
-o-transition-duration: 0.8s;
transition-duration: 0.8s;
}
.test.expand ul li {
display: block;
}
