DOM - 節點物件屬性 - nextSibling



屬性 nextSibling 返回緊隨此節點之後的節點。如果沒有這樣的節點,它將返回 null。

語法

以下是 nextSibling 屬性用法的語法。

nodeObject.nextSibling

示例

node.xml 內容如下 −

<?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>

以下示例展示了 nextSibling 屬性的用法 −

<!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>
         function get_nextsibling(n1) {
            c1 = n1.nextSibling;
            while (c1.nodeType != 1) {
               c1 = c1.nextSibling;
            }
            return c1;
         }

         xmlDoc = loadXMLDoc("/dom/node.xml");

         c1 = xmlDoc.getElementsByTagName("FirstName")[0];
         document.write(c1.nodeName);
         document.write(" and value = ");
         document.write(c1.childNodes[0].nodeValue);

         c2 = get_nextsibling(c1);

         document.write("Name of Next sibling is: ");
         document.write(c2.nodeName);
         document.write(" and value = ");
         document.write(c2.childNodes[0].nodeValue);
      </script>
   </body>
</html>

執行

將此檔案儲存為 nodeattribute_nextsibling.htm,並放到伺服器路徑下(此檔案和 node.xml 應放在伺服器中的同一個路徑)。我們將得到如下所示的輸出 −

FirstName and value = Tanmay
Name of Next sibling is: LastName and value = Patil
dom_node_object.htm
