먼저 아래 그림과 같이 구현 효과를 살펴보겠습니다.
아이디어:
이벤트 결정: 문서 로딩이 완료되었습니다. 2. 이벤트는 다음을 수행해야 합니다. 함수 트리거: init() 3. 함수: 페이지 작동 요소는 테이블의 각 행을 작동하고 행의 배경색을 동적으로 수정해야 합니다.
특정 코드:
<!DOCTYPE html> <html> <head> <meta charset="UTF-8"> <title>Title</title> <script > function init(){ //得到表格 var tab = document.getElementById("tab"); //得到表格中每一行 var rows = tab.rows; //便利所有的行,然后根据奇数 偶数 for(var i=1; i < rows.length; i++){ var row = rows[i]; //得到其中的某一行 if(i%2==0){ row.bgColor = "yellow"; }else{ row.bgColor = "red" } } } </script> </head> <body onload="init()"> <table border="1px" width="600px" id="tab"> <tr> <td> <input type="checkbox"/> </td> <td>分类ID</td> <td>分类名称</td> <td>分类商品</td> <td>分类描述</td> <td>操作</td> </tr> <tr> <td> <input type="checkbox"/> </td> <td>1</td> <td>手机数码</td> <td>华为,小米,尼康</td> <td>黑马数码产品质量最好</td> <td> <a href="#" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" >修改</a>|<a href="#" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" >删除</a> </td> </tr> <tr> <td> <input type="checkbox"/> </td> <td>2</td> <td>成人用品</td> <td>充气的</td> <td>这里面的充气电动硅胶的</td> <td><a href="#" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" >修改</a>|<a href="#" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" >删除</a></td> </tr> <tr> <td> <input type="checkbox"/> </td> <td>3</td> <td>电脑办公</td> <td>联想,小米</td> <td>笔记本特卖</td> <td><a href="#" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" >修改</a>|<a href="#" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" >删除</a></td> </tr> <tr> <td> <input type="checkbox"/> </td> <td>4</td> <td>馋嘴零食</td> <td>辣条,麻花,黄瓜</td> <td>年货</td> <td><a href="#" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" >修改</a>|<a href="#" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" >删除</a></td> </tr> <tr> <td> <input type="checkbox"/> </td> <td>5</td> <td>床上用品</td> <td>床单,被套,四件套</td> <td>都是套子</td> <td><a href="#" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" >修改</a>|<a href="#" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" >删除</a></td> </tr> </table> </body> </html>
