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"> <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> <td>20/07/1997</td> <td>Mrs Jones</td> <td>12010</td> </tr> <tr> <td>Jane Toad</td> <td>21/07/1997</td> <td>Mrs Jones </td> <td>12030</td> </tr> <tr> <td>Amanda Williams</td> <td>19/03/1997</td> <td>Mrs Edwards</td> <td>12021</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', ''); } } </script> </body> </html>
希望本文所述对大家的javascript程序设计有所帮助。
