DOM Node物件屬性nextSibling

DOM Node物件屬性nextSibling返回緊跟此節點後的節點。如果沒有這樣的節點，則返回null。

語法

以下是使用nextSibling屬性的語法。

nodeObject.nextSibling

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nextSibling屬性的用法，檔案：nextsibling.html -

<!DOCTYPE html>
<html>
   <head>
      <meta charset="utf-8"/>
      <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("/node.xml");

         c1 = xmlDoc.getElementsByTagName("FirstName")[0];
         document.write(c1.nodeName);
         document.write("，它的值 =  ");
         document.write(c1.childNodes[0].nodeValue);

         c2 = get_nextsibling(c1);

         document.write("<br/>下一個兄弟節點的名稱是: ");
         document.write(c2.nodeName);
         document.write(" ，它的值 = ");
         document.write(c2.childNodes[0].nodeValue);
      </script>
   </body>
</html>
