1.获取
tBodies tHead tFoot rows cells
例如:
<table id="tab1" border="1" width="500"> <td>ID</td> <td>姓名</td> <td>年龄</td> <tr> <td>1</td> <td>张三</td> <td>12</td> </tr> <tr> <td>2</td> <td>里斯</td> <td>12</td> </tr> <tr> <td>3</td> <td>无望</td> <td>14</td> </tr> <tr> <td>4</td> <td>王五</td> <td>124</td> </tr> <tr> <td>4</td> <td>王位</td> <td>134</td> </tr> </table>
获取 张三
var oTab = document.querySelector("#tab1"); var td = oTab.getElementsByTagName("tbody")[0].getElementsByTagName('tr')[1].getElementsByTagName('td')[1].innerHTML;
针对表格的获取方法
var td = oTab.tBodies[0].rows[1].cells[1].innerHTML;
隔行变色
var oTab = document.querySelector("#tab1"); for(var i=0;i<oTab.tBodies[0].rows.length;i++){ if(i%2){ oTab.tBodies[0].rows[i].style.background="red" } }
添加鼠标移入移出效果
var oTab = document.querySelector("#tab1"); var oldColor=""; for(var i=0;i<oTab.tBodies[0].rows.length;i++){ /*鼠标移入*/ oTab.tBodies[0].rows[i].onmouseover=function(){ oldColor=this.style.background;//保存旧的颜色值防止鼠标移除后把原来的底色修改掉 this.style.background="red" } oTab.tBodies[0].rows[i].onmouseout=function(){ this.style.background=oldColor; } if(i%2){ oTab.tBodies[0].rows[i].style.background="#DDD" } }
