1.一般的表格结构如下
<table> <tr> <td>id</td> <td>name</td> </tr> <tr> <td>1</td> <td>fdipzone</td> </tr> <tr> <td>2</td> <td>wing</td> </tr> </table>
2.遍历表格中所有内容方法
首先需要給table加上id，这样方便定位到哪一个表格，例如
<table id="mytable"></table>
获取表格行数
<script type="text/javascript"> /** * 获取表格行数 * @param Int id 表格id * @return Int */ function getTableRowsLength(id){ var mytable = document.getElementById(id); return mytable.rows.length; } </script>
获取表格某一行列数
<script type="text/javascript"> /** * 获取表格某一行列数 * @param Int id 表格id * @param Int index 行数 * @return Int */ function getTableRowCellsLength(id, index){ var mytable = document.getElementById(id); if(index<mytable.rows.length){ return mytable.rows[index].cells.length; }else{ return 0; } } </script>
遍历表格内容保存到数组
<script type="text/javascript"> /** * 遍历表格内容返回数组 * @param Int id 表格id * @return Array */ function getTableContent(id){ var mytable = document.getElementById(id); var data = []; for(var i=0,rows=mytable.rows.length; i<rows; i++){ for(var j=0,cells=mytable.rows[i].cells.length; j<cells; j++){ if(!data[i]){ data[i] = new Array(); } data[i][j] = mytable.rows[i].cells[j].innerHTML; } } return data; } </script>
