In all examples, we will use the XML file books.xml, and the JavaScript function loadXMLDoc().

The following code fragment gets name and node type from the owner document of the first <title> element in "books.xml":
下面的代码片断将获取“books.xml”文件中的第一个<title>元素所属文档的名称和节点类型:
xmlDoc=loadXMLDoc("books.xml"); var x=xmlDoc.getElementsByTagName("title")[0]; x=x.ownerDocument; document.write("Nodename: " + x.nodeName); document.write(" (nodetype: " + x.nodeType + ")"); |
The output of the code above will be:
上述代码将输出下面的结果:
Nodename: #document (nodetype: 9) |
ownerDocument - Get the owner document of a node
ownerDocument - 获取节点的所属文档
