</table>我有这样一个表格，js如何能获取到<td>属性为namecount那一列的所有数据？？？

Answer 1

在创建表格时用循环,使该列每行的ID都加上一个序列号,然后在JS里用循环的方法获得:
document.getElementById("nameCount"+i).innerHTML
i是循环变量.

Answer 2

var tds =  document.getElementsByTagName("td");
             for(var i = 0 ;i<tds.length;i++){
                 if(tds[i].name=="nameCount")alert("index:"+i +"  innerHTML:"+tds[i].innerHTML); 
             }

Answer 3

循环判断，用 getAttribute 获取属性值
