jquery 选中
<TD style="WHITE-SPACE: nowrap"><INPUT id=tveen3CheckBox title=区间1 type=checkbox name=tveen3CheckBox><A id=tveet3 class=tvee_0 href="javascript:SelectTreeNode(this, '132','0','区间1')">区间1</A></TD>
function SelectTreeNode(obj,nid,deph,nodename)
{
//如何将该A 标签平级的checkbox勾选上，下面这种方式不行啊
$(obj.parentElement).find(':checkbox').checked=true;
}
[解决办法]
function SelectTreeNode(that) { var c= $(that).siblings("input"); c.attr("checked",!c.attr("checked")); return false; }

自己看吧，有你要的东东
