本文實例講述了Javascript遞歸打印Document層次關系的方法。分享給大家供大家參考。具體如下：
<html xmlns="http://www.w3.org/1999/xhtml"><head><meta http-equiv="Content-Type" content="text/html; charset=utf-8" /><title>遞歸顯示節點層次關系</title><script type="text/javascript">var ResultStr = "";function ListNode(node,level) { PrintInfo(node, level); level++; var nodes = node.childNodes; for (var i = 0; i < nodes.length; i++) { if (nodes[i].hasChildNodes()) { ListNode(nodes[i], level); //遞歸 } else { PrintInfo(nodes[i], level); } }}function getSpace(level) { var s = ""; for (var i = 0; i < level; i++) { s+="!----" } return s;}function PrintInfo(node, level) { ResultStr += getSpace(level) + "Name:" + node.nodeName + "...Type:" + node.nodeType + "...Value:" + node.nodeValue + "<br />";}function getDocAllInfo() { ResultStr = ""; ListNode(document, 0); document.write(ResultStr);}</script></head><body><input type="button" value="測試" onclick="getDocAllInfo()" /><div id="divDemo">div內容</div><table> <tr> <td>單元格1</td> <td>單元格2</td> </tr> <tr> <td>單元格3</td> <td>單元格4</td> </tr></table><input type="text" /><span>我是SPAN</span><!--我是注釋--></body></html>希望本文所述對大家的javascript程序設計有所幫助。
