本文实例讲述了Javascript递归打印Document层次关系的方法。分享给大家供大家参考。具体如下：
<html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <title>递归显示节点层次关系</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); //递归 } 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="测试" /> <div id="divDemo">div内容</div> <table> <tr> <td>单元格1</td> <td>单元格2</td> </tr> <tr> <td>单元格3</td> <td>单元格4</td> </tr> </table> <input type="text" /> <span>我是SPAN</span> <> </body> </html>
希望本文所述对大家的javascript程序设计有所帮助。
