DOM - 节点对象属性 - nodeValue

特性nodeValue用于指定节点的值，具体取决于它们的类型。

语法

以下是nodeValue特性用法的语法。

nodeObject.nodeValue

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>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>

以下示例演示了nodeValue特性的用法 -

<!DOCTYPE html>
<html>
   <body>
      <div>
         <b>FirstName:</b><span id = "FirstName"></span><br>
         <b>LastName:</b> <span id = "LastName"></span><br>

      </div>
      <script>
         if (window.XMLHttpRequest) {// code for IE7+, Firefox, Chrome, Opera, Safari
            xmlhttp = new XMLHttpRequest();
         } else {// code for IE6, IE5
            xmlhttp = new ActiveXObject("Microsoft.XMLHTTP");
         }
         xmlhttp.open("GET","/dom/node.xml",false);
         xmlhttp.send();
         xmlDoc = xmlhttp.responseXML;

         document.getElementById("FirstName").innerHTML =
         xmlDoc.getElementsByTagName("FirstName")[0].childNodes[0].nodeValue;
         document.getElementById("LastName").innerHTML =
         xmlDoc.getElementsByTagName("LastName")[0].childNodes[0].nodeValue;

      </script>
   </body>
</html>

执行

将此文件保存为nodeattribute_nodevalue.htm（此文件和 node.xml 应在服务器中的同一路径）。我们将获得如下所示的输出 -

FirstName: Tanmay
LastName: Patil

dom_node_object.htm
