Answer 1

什么意思，要获取第一个table的第一行第二个单元格里的值吗？alert($("table").eq(0).find("td").eq(1).html());

Answer 2

但是整个页面中有很的的table怎么办啊？您写这个只是获取第一人Table的值，如是在前面还有table的话就不行了，主要是想获取  “压力测试” 这个题名的值 

Answer 3

$("div.panelContent table").find("tr").first().find("td").last().text();

Answer 4

首先你要找出你的这个需要获取的目标的标识，就是说，不管我页面有多少相同的元素，我的这个目标有唯一的一个标识可以定位到它。比如说每个表格第一行的第二列或者前后有什么可以定位它的元素也行，大体就是这个意思。如果你的不是动态生成的，那么就直接加ID属性。其实你如果动态生成的话也可以动态的添加ID属性，你自己定义的id构成，取的时候也是很方便。

Answer 5

如5楼所说，要是有个标识（id、class，或者自定义一个属性都可以），就好办了。
如果不能添加标识，那是否能确定这个table是第几个
如果也不能，那就只能找规律了，
比如这个table一共有9行，每行有2个td，在第几行里面会出现<b>标签等等，
然后遍历整个页面上的table，找到最符合规定的。
但是如果连规律都没有，那就没办法了
