编写一个方法,输入DOM节点,返回包含所有父节点的一个数组 function getParentsNodes(element) { var parents = []; var getParentsNode = function (element) { if (element.parentNode) { parents.push(element.parentNode); getParentsNode(element.parentNode); } }; getParentsNode(element)
Given a binary search tree (BST), find the lowest common ancestor (LCA) of two given nodes in the BST. According to the definition of LCA on Wikipedia: “The lowest common ancestor is defined between two nodes v and w as the lowest node in T that has

1,DOM操作 1.1 概念 所谓DOM,全称Document Object Model 文档对象模型,DOM是W3C(World Wide Web Consortuum )标准,同时也定义了访问诸如XML和HTML文档的标准.DOM是一个使程序和脚本有能力动态地访问和更新文档的内容,结构以及样式的平台和语言中立的接口. 在文档中一切皆对象,比如 html,body,div,p等等都看做对象,那么我们如何来点击某个盒子让他变色呢? DOM 为文档提供了结构化表示,并定义了如何通过脚本来访问文档
