Chapter 3 DynaScript Predefined Objects

DOMImplementation methods

The DOMImplementation object has these methods:

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
