Chapter 3 DynaScript Predefined Objects

DOMImplementation object

Object

Provides a means of querying the capabilities of this application's implementation of DOM.

Syntax

To use a DOMImplementation's method:

DOMImplementation.MethodName( parameter )

Description

The DOMImplementation object has one method used to query the features supported by this specific implementation of DOM. This method is independent of any particular instance of a DOMDocument .

Dynamo's current implementation of DOM supports parsing of XML 1.0 documents according to DOM Level 1.

hasFeature method

Syntax

DOMImplementation.hasFeature( feature, version )

Description

Tests if the DOM implementation includes a specific feature. The parameters are:

feature The package name of the feature to test. This can be "HTML" or "XML".
version The version number of the package to test. Currently, the only valid value for this parameter is "1.0", because Dynamo supports XML 1.0.

Return

Boolean. True if the feature is implemented in the specified version, false otherwise.

Example

To write out the features supported by the Dynamo XML parser, enter:

domDoc = new DOMDocument();
implementation = domDoc.implementation;
document.writeln( "HTML? " + implementation.hasFeature( "HTML", "1.0" ) ) ;
document.writeln( "XML? " + implementation.hasFeature( "XML", "1.0" ) );

The output is:

HTML? false
XML? true
