DOM Node物件屬性nodeType是表示底層物件型別的程式碼。
語法
以下是nodeType屬性的使用語法。
nodeObject.nodeType
範例
檔案：node.xml 的內容如下 -
<Company>
<Employee category = "Technical" id = "firstelement">
<FirstName>Susen</FirstName>
<LastName>Su</LastName>
<ContactNo>1584567890</ContactNo>
<Email>[email protected]</Email>
</Employee>
<Employee category = "Non-Technical">
<FirstName>Max</FirstName>
<LastName>Su</LastName>
<ContactNo>1334667898</ContactNo>
<Email>[email protected]</Email>
</Employee>
<Employee category = "Management">
<FirstName>Min</FirstName>
<LastName>Su</LastName>
<ContactNo>1364562350</ContactNo>
<Email>[email protected]</Email>
</Employee>
</Company>
以下範例演示了nodeType屬性的用法，檔案：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>
執行上在範例程式碼，得到以下結果 -
