javascript getElementsByTagName实现中的DOM遍历

[英]DOM traversal in implementations of javascript getElementsByTagName

原文 2014-06-27 19:49:30 3 1 javascript/ dom/ tree-traversal

What method(s) of DOM (tree) traversal do implementations of the javascript function getElementsByTagName use? javascript函数getElementsByTagName的实现使用DOM（树）遍历的哪些方法？ I ask because I'd like to be sure that the array returned by getElementsByTagName contains DOM elements in an order roughly from the top of the document to the bottom, which would be the case in a depth-first search of the DOM tree, for instance. 我问，是因为我想确保getElementsByTagName返回的数组包含DOM元素的顺序大致是从文档顶部到底部，在DOM树的深度优先搜索中就是这种情况，实例。
