jQuery实现弹出层效果

时间:2021-04-02 人气:0

###jQuery实现弹出层效果

点击弹出层：弹出弹出层
点击阴影：关闭弹出层
点击“关闭”关闭弹出层

整体代码如下：

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

<head>
 <meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
 <title>jQuery弹出层效果</title>
 <style>
  .black_overlay {
   display: none;
   position: absolute;
   top: 0%;
   left: 0%;
   width: 100%;
   height: 100%;
   background-color: black;
   z-index: 1001;
   -moz-opacity: 0.8;
   opacity: .80;
   filter: alpha(opacity=80);
  }

  .white_content {
   display: none;
   position: absolute;
   top: 10%;
   left: 10%;
   width: 80%;
   height: 80%;
   border: 16px solid lightblue;
   background-color: white;
   z-index: 1002;
   overflow: auto;
  }

  .white_content_small {
   display: none;
   position: absolute;
   top: 20%;
   left: 30%;
   width: 40%;
   height: 50%;
   border: 16px solid lightblue;
   background-color: white;
   z-index: 1002;
   overflow: auto;
  }
 </style>
 <script type="text/javascript">
  //弹出隐藏层
  function ShowDiv(show_div, bg_div) {
   document.getElementById(show_div).style.display = 'block';
   document.getElementById(bg_div).style.display = 'block';
   var bgdiv = document.getElementById(bg_div);
   bgdiv.style.width = document.body.scrollWidth;
   // bgdiv.style.height = $(document).height();
   $("#" + bg_div).height($(document).height());
  };
  //关闭弹出层
  function CloseDiv(show_div, bg_div) {
   document.getElementById(show_div).style.display = 'none';
   document.getElementById(bg_div).style.display = 'none';
  };
 </script>
</head>

<body>
 <input id="Button1" type="button" value="点击弹出层" onclick="ShowDiv('MyDiv','fade')" />
 <!--弹出层时背景层DIV-->
 <div id="fade" class="black_overlay" onclick="CloseDiv('MyDiv','fade')">
 </div>
 <div id="MyDiv" class="white_content">
  <div style="text-align: right; cursor: default; height: 40px;">
   <span style="font-size: 16px;" onclick="CloseDiv('MyDiv','fade')">关闭</span>
  </div>
  目前来说，我还是喜欢这个自己改造的弹出层。自己在项目中也用的是这个。
 </div>
</body>

</html>
