本文實(shí)例講述了JS讀取XML文件數(shù)據(jù)并以table形式顯示數(shù)據(jù)的方法。分享給大家供大家參考，具體如下：
先看xml文件：
代碼如下:
<?xml version="1.0" standalone="yes"?>
<student>
<stuinfo>
<stuName>張秋麗</stuName>
<stuSex>女 </stuSex>
<stuAge>18</stuAge>
</stuinfo>
<stuinfo>
<stuName>李文才</stuName>
<stuSex>男 </stuSex>
<stuAge>31</stuAge>
</stuinfo>
<stuinfo>
<stuName>李斯文</stuName>
<stuSex>男 </stuSex>
<stuAge>22</stuAge>
</stuinfo>
<stuinfo>
<stuName>馬英</stuName>
<stuSex>女 </stuSex>
<stuAge>25</stuAge>
</stuinfo>
<stuinfo>
<stuName>孫紅雷</stuName>
<stuSex>男 </stuSex>
<stuAge>32</stuAge>
</stuinfo>
<stuinfo>
<stuName>歐陽(yáng)俊雄</stuName>
<stuSex>男 </stuSex>
<stuAge>28</stuAge>
</stuinfo>
<stuinfo>
<stuName>江琳</stuName>
<stuSex>女 </stuSex>
<stuAge>23</stuAge>
</stuinfo>
<stuinfo>
<stuName>小小</stuName>
<stuSex>女 </stuSex>
<stuAge>22</stuAge>
</stuinfo>
</student>
aspx頁(yè)面代碼：
代碼如下:
<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="獲取數(shù)據(jù)庫(kù)數(shù)據(jù)生成XML.aspx.cs" Inherits="Chapter1.獲取數(shù)據(jù)庫(kù)數(shù)據(jù)生成XML" %>

<script type="text/javascript">
function loadXMLDoc(dname) {
if (window.XMLHttpRequest) {
xhttp = new XMLHttpRequest();
}
else {
xhttp = new ActiveXObject("Microsoft.XMLHTTP");
}
xhttp.open("GET", dname, false);
xhttp.send("");
return xhttp.responseXML;
}
function ReadXml() {
var xmldoc = loadXMLDoc("Student.xml");
//獲得指定節(jié)點(diǎn)
var divmsg = document.getElementById("xmlMsg");
var msg = "<table border='1' id='mytable'><tr><th>姓名</th><th>性別</th><th>年齡</th><tr>";
var nodes = xmldoc.getElementsByTagName("stuinfo");
for (var i = 0; i < nodes.length; i++) {
msg += "<tr>";
msg += "<td>" + nodes[i].getElementsByTagName("stuName")[0].firstChild.nodeValue + "</td>";
msg += "<td>" + nodes[i].getElementsByTagName("stuSex")[0].firstChild.nodeValue + "</td>";
msg += "<td>" + nodes[i].getElementsByTagName("stuAge")[0].firstChild.nodeValue + "</td>";
msg += "</tr>";
}
msg += "</table>";
divmsg.innerHTML = msg;
}
</script>
</head>
<body>
<form id="form1" runat="server">
<div>
<input type="button" value="JS讀取XML" onclick="ReadXml()" /><br />
<div id="xmlMsg">
</div>
</div>
</form>
</body>
</html>
上面的JS操作主要就避免了使用childNodes(因?yàn)榛鸷杏袝r(shí)候會(huì)出現(xiàn)childNodes[0]獲取到的是"\n"而不是我們想要的第一個(gè)子節(jié)點(diǎn)，這個(gè)自己可以去試下，反正我是遇到了這種情況),使得可以兼容IE、火狐，其他瀏覽器我沒試。
希望本文所述對(duì)大家JavaScript程序設(shè)計(jì)有所幫助。
