This time I will bring you jQuery to bind mouse rollover events to DIVs (with code). What are the precautions for jQuery to bind mouse rollover events to DIVs? The following is a practical case. Get up and take a look.

<!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 is positioned through

position:absoluteabsolute positioning , and positioned relative to the bottom, 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.

I believe you have mastered the method after reading the case in this article. For more exciting information, please pay attention to other related articles on the php Chinese website!
