DOM - 节点对象属性 - childNodes



属性 childNodes 用于描述 NodeList 中一个节点的子节点。

语法

以下是 childNodes 属性的用法语法。

nodeObject.childNodes

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>[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 childNodes 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.childNodes;
         for (i = 0;i < x.length;i ++) {
            document.write("Nodename: " + x[i].nodeName);
            document.write(" (nodetype: " + x[i].nodeType + ")<br>");
         }
      </script>
   </body>
</html>

执行

将此文件另存为服务器路径上的 nodeattribute_childnodes.htm(此文件和 node.xml 应该在服务器上的同一路径中)。我们将获得如下所示的输出 −

Nodename: Company (nodetype: 1)
dom_node_object.htm
