我目前正在我的网站上工作
footer
,如果用户单击Contact Us
,页脚后面就会出现一个黄色的div。
这是我目前正在做的事情,但我似乎无法定位隐藏在页脚后面的黄色框。黄色区域可见时高度约为 300 像素。
var clicked=true;
$(".one").on('click', function(){
if(clicked)
{
clicked=false;
$(".two").css({"top": 0});
}
else
{
clicked=true;
$(".two").css({"top": "40px"});
}
});
footer {
width:100%;
display:block;
background:#ccc;
position:fixed;
bottom:0;
left:0
}
.container {
overflow:hidden;
height: 60px;
float:left;
}
.one {
position: relative;
bottom: 0;
background-color: lightblue;
z-index: 1;
cursor:pointer;
overflow: hidden;
height: 40px;
}
.two {
position: relative;
bottom: 40px;
background-color: yellow;
z-index: -1;
-webkit-transition: top 1s;
-moz-transition: top 1s;
-o-transition: top 1s;
transition: top 1s;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.7.2/jquery.min.js"></script>
<div class="container">
<div class="two">I slide!<br>And I am higher than the div before me...</div>
</div>
<footer>
<ul>
<li><a href="">Privacy Policy</a></li>
<li><a href="#" class="one">Contact Us</a></li>
</ul>
</footer>
这是工作幻灯片:
.container {
overflow: hidden;
height: 60px;
float: left;
position: absolute; /*add this, and */
bottom: 20px; /* this*//*pixel based on what you wish*/
}
更新的演示:
检查更新小提琴这里
试试这个。它使用 jQuery animate 来滑动。
JS
var clicked=true;
$(".one").on('click', function(){
if(clicked)
{
clicked=false;
$(".container").animate({"bottom": "0px"});
}
else
{
clicked=true;
$(".container").animate({"bottom": "40px"});
}
});

}
.container {
overflow:hidden;
height: 40px;
position: absolute;
bottom:0;
width: 100%;
z-index: 1;
}
.one {
