DOM Node对象属性nodeType是表示底层对象类型的代码。
语法
以下是nodeType属性的使用语法。
nodeObject.nodeType
示例
文件：node.xml 的内容如下 -
<Company>
<Employee category = "Technical" id = "firstelement">
<FirstName>Susen</FirstName>
<LastName>Su</LastName>
<ContactNo>1584567890</ContactNo>
<Email>susen@xuhuhu.com</Email>
</Employee>
<Employee category = "Non-Technical">
<FirstName>Max</FirstName>
<LastName>Su</LastName>
<ContactNo>1334667898</ContactNo>
<Email>maxsu@xuhuhu.com</Email>
</Employee>
<Employee category = "Management">
<FirstName>Min</FirstName>
<LastName>Su</LastName>
<ContactNo>1364562350</ContactNo>
<Email>minsu@xuhuhu.com</Email>
</Employee>
</Company>
以下示例演示了nodeType属性的用法，文件：nodetype.html -
<!DOCTYPE html>
<html>
<head>
<script>
function loadXMLDoc(filename) {
if (window.XMLHttpRequest) {
xhttp = new XMLHttpRequest();
} else{ // code for IE5 and IE6
xhttp = new ActiveXObject("Microsoft.XMLHTTP");
}
xhttp.open("GET",filename,false);
xhttp.send();
return xhttp.responseXML;
}
</script>
</head>
<body>
<script>
xmlDoc = loadXMLDoc("/node.xml");
document.write("Nodename: " + xmlDoc.nodeName);
document.write(" (nodetype: " + xmlDoc.nodeType + ") <br>");
x = xmlDoc.documentElement;
document.write("Nodename: " + x.nodeName);
document.write(" (nodetype: " + x.nodeType + ") <br>");
</script>
</body>
</html>
