创建一个元素var indexTable=document.createElement(类型);
往元素里边增加一个子节电indexTable.appendChild(子节点);
基本上大部分的HTML都可以通过这种方式构成
HTML里边的Table把
例如
<table>
<tr>
<td></td>
<td></td>
</tr>
</table>
首先创建一个table的元素
var indexTable=document.createElement("table");
然后创建一列
var indexTR=document.createElement("tr");
接着创建行
Var indexTD1=document.createElement("td");
Var indexTD2=document.createElement("td");
然后就是将节点组合起来了
indexTR.appendChild(indexTD1);
indexTR.appendChild(indexTD2);
indexTable.appendChild(indexTR);
然后追加到页面上去document.body.appendChild(indexTable);
虽然照平时写的HTML里边的Table是这样的,不过其实有个问题,就是缺少了<tbody>,这个元素,其实是看不到表的。
所以在用JS生成表时,必须再table的元素后边加上tbody然后再追加tr和td
JS里边生成Table个结构应该是这样的
<table>
<tbody>
<tr>
<td></td>
<td></td>
</tr>
<tbody>
</table>
别少了<tbody>这个元素。。。。。
