语法

下面是 value 属性的用法语法。

attrObject.ownerElement

示例

node.xml 内容如下所示 −

<?xml version = "1.0"?>
<Company>
   <Employee category = "Technical">
      <FirstName>Tanmay</FirstName>
      <LastName>Patil</LastName>
      <ContactNo>1234567890</ContactNo>
      <Email>[email protected]</Email>
   </Employee>
   
   <Employee category = "Non-Technical">
      <FirstName>Taniya</FirstName>
      <LastName>Mishra</LastName>
      <ContactNo>1234667898</ContactNo>
      <Email>[email protected]</Email>
   </Employee>
   
   <Employee category = "Management">
      <FirstName>Tanisha</FirstName>
      <LastName>Sharma</LastName>
      <ContactNo>1234562350</ContactNo>
      <Email>[email protected]</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

将该文件作为 domattribute_ownerelement.html 保存到服务器路径(该文件和 node.xml 应当位于服务器中的同一路径)。我们会获得如下所示的输出 −

Owner is : [object Element]
Owner Name of attribute node is : Employee 
dom_attribute_object.htm
