我想得到两个职位：
market 名字来自 <td class="yui-dt-col-market" data-column-id="market">
sell 价值来自 <td class="yui-dt-col-sell" data-column-id="sell">
但我不知道如何从tbody.
有两个tr对象，我认为它应该加载到数组中。
请不要使用 jQuery 解决方案。
任何的想法？
您可以使用它：1) 从 tbody 中获取所有行 2) 从每一行中获取所有 'td'
var rows =document.getElementsByTagName("tbody")[0].rows;
for(var i=0;i<rows.length;i++){
var td = rows[i].getElementsByTagName("td")[i];
console.log(td)
}
比对这个 td 对象做任何你想做的事情。
