DOM Node对象属性nextSibling

DOM Node对象属性nextSibling返回紧跟此节点后的节点。 如果没有这样的节点,则返回null

语法

以下是使用nextSibling属性的语法。

nodeObject.nextSibling

示例
文件:node.xml 的内容如下 -

<Company> 
   <Employee category = "Technical" id = "firstelement"> 
      <FirstName>Susen</FirstName> 
      <LastName>Su</LastName> 
      <ContactNo>1584567890</ContactNo> 
      <Email>susen@xuhuhu.com</Email> 
   </Employee>  

   <Employee category = "Non-Technical"> 
      <FirstName>Max</FirstName> 
      <LastName>Su</LastName> 
      <ContactNo>1334667898</ContactNo> 
      <Email>maxsu@xuhuhu.com</Email> 
   </Employee>  

   <Employee category = "Management"> 
      <FirstName>Min</FirstName> 
      <LastName>Su</LastName> 
      <ContactNo>1364562350</ContactNo> 
      <Email>minsu@xuhuhu.com</Email> 
   </Employee> 
</Company>

以下示例演示了nextSibling属性的用法,文件: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/>下一个兄弟节点的名称是: ");
         document.write(c2.nodeName);
         document.write(" ,它的值 = ");
         document.write(c2.childNodes[0].nodeValue);
      </script>
   </body>
</html>

执行上面示例代码,得到以下结果 -
