The example in this article describes the JS implementation of the retractable window code with animation effects on the right side of the web page. Share it with everyone for your reference, the details are as follows:

This is a fixed retractable window on the right side of the web page with a buffering effect. Click on the colored area, and the floating layer window will expand and contract, and click again to shrink it. No jQuery, the effect is completely implemented in JavaScript.

The screenshot of the running effect is as follows:

The online demo address is as follows:

The specific code is as follows:

<html xmlns="http://www.w3.org/1999/xhtml">

<title>带缓冲效果的网页右侧固定伸缩窗口</title>
<meta http-equiv="content-type" content="text/html;charset=gb2312">
<style type="text/css">
#common_box{width:300px;position:fixed;_position:absolute;right:0;top:40%;border:1px solid #789;background:#fff;z-index:88}
#cli_on{width:30px;height:180px;float:left;cursor:pointer;background:#ac8932;text-align:center;line-height:180px}
</style>
</head>
<body>
<div style="width:100%;height:1024px;background:#789"></div>
<div id="common_box">
 <div id="cli_on">+</div>
 <div>
  这里放置菜单内容
 </div>
</div>
<script type="text/javascript">
window.onload = function() {
 var combox = document.getElementById("common_box");
 var cli_on = document.getElementById("cli_on");
 var flag = true, timer = null, initime = null, r_len = 0;
 cli_on.onclick = function () {
  /*如果不需要动态效果，这两句足矣
  combox.style.right = flag&#63;'-270px':0;
  flag = !flag;
  */
  clearTimeout(initime);
  //根据状态flag执开展开收缩
  if (flag) {
   r_len = 0;
   timer = setInterval(slideright, 10);
  } else {
   r_len = -270;
   timer = setInterval(slideleft, 10);
  }
 }
 //展开
 function slideright() {
  if (r_len <= -270) {
   clearInterval(timer);
   flag = !flag;
   return false;
  } else {
   r_len -= 5;
   combox.style.right = r_len + 'px';
  }
 }
 //收缩
 function slideleft() {
  if (r_len >= 0) {
   clearInterval(timer);
   flag = !flag;
   return false;
  } else {
   r_len += 5;
   combox.style.right = r_len + 'px';
  }
 }
 //加载后3秒页面自动收缩
 initime = setTimeout("cli_on.click()", 3000);
}
</script>
</body>
</html>
