DOMImplementation interface represents an object providing methods which are not dependent on any particular document. Such an object is returned by the Document.implementation 特性。

特性

This interface has no specific property and doesn't inherit any.

方法

No inherited method.

DOMImplementation.createDocument(): Creates and returns an XMLDocument .
DOMImplementation.createDocumentType(): 创建并返回 DocumentType .
DOMImplementation.createHTMLDocument(): Creates and returns an HTML Document .
DOMImplementation.hasFeature(): 返回 布尔 indicating if a given feature is supported or not. This function is unreliable and kept for compatibility purpose alone: except for SVG-related queries, it always returns true . Old browsers are very inconsistent in their behavior.
