本文实例讲述了javascript禁止访客复制网页内容的方法。分享给大家供大家参考。具体如下:

使用JavaScript禁止用户复制网页上的内容,让鼠标选择功能失效,你可以试一下,加入了onselectstart=return false"后,在网页上不能选中文字,浏览者也就无法复制网页内容了。

其实这种方法并不能完全禁止复制,用户可通过网页另存为或更换浏览器来实现复制功能。

实现代码:

<html>
<head>
<title>禁止用户复制网页内容</title>
</head>
<body onselectstart="return false">
<table width="782" height="532" border="0" align="center" cellpadding="0" cellspacing="0" background="bg.jpg">
 <tr>
  <td width="594" height="165"> </td>
  <td width="188" height="165"> </td>
 </tr>
 <tr>
  <td height="367" align="left" valign="top" style="text-indent:5px; font-size:12px">JavaScript中文网
   <p>学习编程</p>
   <p>努力成为广大脚本技术爱好者的“家”, </p>
   <p> 让大家在这里能找到归属感!</p>
   <p>网站提供大量的asp、php、asp .net、javascript、jquery、vbscript、dos批处理、网页制作、网络编程等特色内容。 </p>
  </td>
  <td height="367"> </td>
 </tr>
</table>
</body>
</html>

希望本文所述对大家的javascript程序设计有所帮助。

本文实例讲述了JS+CSS实现表格高亮的方法。分享给大家供大家参考。具体如下:

这里使用JavaScript+CSS实现表格高亮的功能,实际上类似于隔行换色的效果,说法不同而已,只不过本效果是在鼠标移上时触发,移出结束。

运行效果如下图所示:

具体代码如下:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<title>高亮的表格</title>
<meta http-equiv="content-type"
 content="text/html; charset=iso-8859-1" />
<style>
p, td, th {
  font: 0.8em Arial, Helvetica, sans-serif;
}
.datatable {
  border: 1px solid #D6DDE6;
  border-collapse: collapse;
  width: 80%;
}
.datatable td {
  border: 1px solid #D6DDE6;  
  padding: 4px;
}
.datatable th {
  border: 1px solid #828282;
  background-color: #BCBCBC;
  font-weight: bold;
  text-align: left;
  padding-left: 4px;
}
.datatable caption {
  font: bold 0.9em Arial, Helvetica, sans-serif;
  color: #33517A;
  text-align: left;
  padding-top: 3px;
  padding-bottom: 8px;
}
.datatable tr:hover, .datatable tr.hilite {
  background-color: #DFE7F2;
  color: #000000;
}
</style>
</head>
<body>
<table summary="List of new students 2003" class="datatable">
 <caption>Student List</caption>
 <tr>
 <th scope="col">Student Name</th>
 <th scope="col">Date of Birth</th>
 <th scope="col">Class</th>
 <th scope="col">ID</th>
 </tr>
 <tr>
 <td>Joe Bloggs</td>
 <td>27/08/1997</td>
 <td>Mrs Jones</td>
 <td>12009</td>
 </tr>
 <tr>
 <td>William Smith</td>

 </tr>
</table>
<script type="text/javascript">
var rows = document.getElementsByTagName("tr");
for (var i = 0; i < rows.length; i++) {
  rows[i].onmouseover = function() {
    this.className += " hilite";
  }
  rows[i].onmouseout = function() {
    this.className = this.className.replace("hilite", "");
  }
}
