Public methods |
|
|---|---|
abstract DOMImplementation |
getDOMImplementation(String features) 一种请求支持指定功能的第一个DOM实现的方法。 |
abstract DOMImplementationList |
getDOMImplementationList(String features) 请求一个支持指定功能和版本的DOM实现列表的方法，如中所述。 |
DOMImplementation getDOMImplementation (String features)
一种请求支持指定功能的第一个DOM实现的方法。
| Parameters | |
|---|---|
features |
String: A string that specifies which features and versions are required. This is a space separated list in which each feature is specified by its name optionally followed by a space and a version number. This method returns the first item of the list returned by getDOMImplementationList. As an example, the string "XML 3.0 Traversal +Events 2.0" will request a DOM implementation that supports the module "XML" for its 3.0 version, a module that support of the "Traversal" module for any version, and the module "Events" for its 2.0 version. The module "Events" must be accessible using the method Node.getFeature() and DOMImplementation.getFeature(). |
| Returns | |
|---|---|
DOMImplementation |
The first DOM implementation that support the desired features, or null if this source has none. |
DOMImplementationList getDOMImplementationList (String features)
请求一个支持指定功能和版本的DOM实现列表的方法，如中所述。
| Parameters | |
|---|---|
features |
String: A string that specifies which features and versions are required. This is a space separated list in which each feature is specified by its name optionally followed by a space and a version number. This is something like: "XML 3.0 Traversal +Events 2.0" |
| Returns | |
|---|---|
