DOM - 属性对象属性 - OwnerElement
属性 ownerElement 给出与属性关联的节点，如果未使用属性，则为 null。
语法
以下是使用 value 属性的语法。
attrObject.ownerElement
示例
node.xml 内容如下 −
<?xml version = "1.0"?>
<Company>
<Employee category = "Technical">
<FirstName>Tanmay</FirstName>
<LastName>Patil</LastName>
<ContactNo>1234567890</ContactNo>
<Email>tanmaypatil@xyz.com</Email>
</Employee>
<Employee category = "Non-Technical">
<FirstName>Taniya</FirstName>
<LastName>Mishra</LastName>
<ContactNo>1234667898</ContactNo>
<Email>taniyamishra@xyz.com</Email>
</Employee>
<Employee category = "Management">
<FirstName>Tanisha</FirstName>
<LastName>Sharma</LastName>
<ContactNo>1234562350</ContactNo>
<Email>tanishasharma@xyz.com</Email>
</Employee>
</Company>
以下示例演示了 name 属性的用法 −
<!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("/dom/node.xml");
x = xmlDoc.getElementsByTagName('Employee');
document.write("Owner is : ");
document.write(x.item(0).attributes[0].ownerElement);
document.write("<br>");
document.write("Owner Name of attribute node is : ");
document.write(x.item(0).attributes[0].ownerElement.nodeName);
</script>
</body>
</html>
执行
将此文件另存为 domattribute_ownerelement.html 并保存在服务器路径上(此文件和 node.xml 应位于服务器中的同一路径上)。我们将获得如下所示的输出 −
Owner is : [object Element] Owner Name of attribute node is : Employee
dom_attribute_object.htm
