锚对象

The Anchor object represents an HTML hyperlink. For each instance of an HTML <a> tag in a document, an Anchor object is created.

锚对象可以被用来建立一条到另一文档的连接（通过href属性）或在文档内建立一个书签（用name属性）

You can access an Anchor object by indexing the anchors' array (by number or name) of the Document object or by using getElementById().
你可以通过Document对象或使用getElementById()索引锚的数组(用name的数字)来访问一个锚对象
