- 元素节点的 nodeValue 是 undefined
- 文本节点的 nodeValue 是文本自身
- 属性节点的 nodeValue 是属性的值
例子 1：获取元素的值
下面的代码检索第一个
元素的文本节点的值：</p>
<pre>xmlDoc=loadXMLDoc("books.xml");
x=xmlDoc.getElementsByTagName("title")[0].childNodes[0];
txt=x.nodeValue;</pre>
<p>结果：txt = "Harry Potter"</p>
<h3>代码解释：</h3>
<ul>
<li>通过使用 loadXMLDoc() 把 "books.xml" 载入 xmlDoc 中</li>
<li>获取第一个 <title> 元素节点的文本节点</li>
<li>把 txt 变量设置为文本节点的值</li>
</ul>
<p class="tiy"><a target="_blank" href="/ha/tiy/t.html?f=xdom_getelement">TIY</a></p>
</div>
<div>
<h2>例子 2：更改元素的值</h2>
<p>下面的代码更改第一个 <title> 元素的文本节点的值：</p>
<pre>xmlDoc=loadXMLDoc("books.xml");
x=xmlDoc.getElementsByTagName("title")[0].childNodes[0];
x.nodeValue="Easy Cooking";</pre>
<h3>代码解释：</h3>
<ul>
<li>通过使用 loadXMLDoc() 把 "books.xml" 载入 xmlDoc 中</li>
<li>获取第一个 <title> 元素节点的文本节点</li>
<li>把文本节点的值更改为 "Easy Cooking"</li>
</ul>
<p class="tiy"><a target="_blank" href="/ha/tiy/t.html?f=xdom_changeelement">TIY</a></p>
</div>
<div>
<h2>nodeType 属性</h2>
<p>nodeType 属性规定节点的类型。</p>
<p>nodeType 是只读的。</p>
<h3>最重要的节点类型是：</h3>
<table class="dataintable" style="width:40%;">
<tr>
<th>元素类型</th>
<th>节点类型</th>
</tr>
<tr>
<td>元素</td>
<td>1</td>
</tr>
<tr>
<td>属性</td>
<td>2</td>
</tr>
<tr>
<td>文本</td>
<td>3</td>
</tr>
<tr>
<td>注释</td>
<td>8</td>
</tr>
<tr>
<td>文档</td>
<td>9</td>
</tr>
</table>
