What are the precautions?, here is the actual combat Let’s take a look at the case.
2. Code
<!doctype html>
<html>
<head>
<meta charset="utf-8">
<title>jQuery响应鼠标实现p由下向上展开</title>
<style type="text/css">
.big{position:relative; width:234px; height:300px; background:#ccc}
.show{position:absolute; display:none; bottom:0px;display:block; width:100%; height:auto; background:#f66 }
</style>
<script src="http://libs.baidu.com/jquery/2.0.0/jquery.min.js"></script>
<script type="text/javascript">
$(document).ready(function()
{
$(".big").hover(function () {
$(".show").stop(true,true).animate({height:"70px"});
}, function () {
$(".show").stop(true,true).animate({height:"0px"});
});
});
</script>
</head>
<body>
<!--灰色的p-->
<p class="big">
<!--红色的p-->
<p class="show"></p>
</p>
</body>
</html>Principle:
① First, the red p passesposition:absolute Absolute positioning , and through relative and bottom positioning, such as bottom:0px.
② The bottom positioning is fixed and expands upward when the height becomes higher.
③ Use jQuery’s $().animate() animation method to control the height change of the red p.
