求助table内节点取得的问题

这是一段table的代码。
我想实现选取checkbox就移动整行，上/下。
但是，我对节点不太熟悉，死活取不到tr标签或者td的内容。
哪位给提示一下？应该用到哪些属性？怎么取？
告诉我关键字就行了，谢谢啊~~~分不多~~

先拿到所有checkboxdocument.getElementsByTagName('checkbox');然后循环绑定事件然后拿到当前点击的checkbox，用parentNode.parentNode像上找2个节点，就是tr了
额？能否再详细一点呢？例如，用到什么属性？感觉html的dom太复杂，不熟悉。
document.getElementsByTagName('checkbox').parentNode.parentNode

                    if ($curTR.index() == 0) {              //如果是第一行, 则下移至表格最后一行
