本文實例講述了JS+CSS實現表格高亮的方法。分享給大家供大家參考。具體如下：
這里使用JavaScript+CSS實現表格高亮的功能，實際上類似于隔行換色的效果，說法不同而已，只不過本效果是在鼠標移上時觸發，移出結束。
運行效果如下圖所示：
具體代碼如下：
<!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> <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>希望本文所述對大家的javascript程序設計有所幫助。
