nodeName read-only property returns the name of the current 节点 以字符串形式。

句法

var str = node.nodeName;
					

值

A DOMString . Values for the different types of nodes are:

接口	nodeName value
Attr	值 Attr.name
CDATASection	"#cdata-section"
注释	"#comment"
Document	"#document"
DocumentFragment	"#document-fragment"
DocumentType	值 DocumentType.name
元素	值 Element.tagName
Entity	The entity name
EntityReference	The name of entity reference
Notation	The notation name
ProcessingInstruction	值 ProcessingInstruction.target
文本	"#text"

范例

Given the following markup:

<div id="d1">hello world</div>
<input type="text" id="t">
					

and the following script:

var div1 = document.getElementById("d1");
var text_field = document.getElementById("t");
text_field.value = div1.nodeName;
					

In XHTML (or any other XML format), text_field 's value would read "div" . However, in HTML, text_field 's value would read "DIV" ，因为 nodeName and tagName return in upper case on HTML elements in DOMs flagged as HTML documents. Read more details on nodeName case sensitivity in different browsers .

注意， Element.tagName property could have been used instead, since nodeName has the same value as tagName for an element. Bear in mind, however, that nodeName 将返回 "#text" for text nodes while tagName 将返回 undefined .
