1. Introduction

In this web page there are two web browser JavaScript feature support tests; 1.) a feature implementation test, and 2.) a feature capability test. First, the implementation test is run. The implementation test determines if the web browser recognizes the JavaScript dataset property. The implementation test is a simple test for the presence of web browser support, and a definitive test for the absence of web browser support. If the web browser does not recognize the JavaScript dataset property, the testing is stopped and the implementation test reports: Fail (no support): The web browser does not recognize the JavaScript dataset property. The web browser does not support the JavaScript dataset property.

If the web browser recognizes the JavaScript dataset property, the capability test is run. The capability test determines if the web browser's implementation of the JavaScript dataset property includes support for at least one dataset property capability. The capability test is a more definitive, albeit not an all inclusive, test for the presence of web browser support. If the web browser's implementation of the JavaScript dataset property includes support for the tested capability, the capability test reports: Pass (at least partial/possibly full support): The web browser recognizes the JavaScript dataset property, and supports at least one dataset property capability. The web browser at least partially/possibly fully supports the JavaScript dataset property. Positive determination of full web browser support is beyond the scope of this test. If the web browser's implementation of the JavaScript dataset property does not include support for the tested capability, the capability test reports: Pass/Fail (partial support): The web browser recognizes the JavaScript dataset property, but does not support at least one dataset property capability. The web browser partially supports the JavaScript dataset property.

The web browser support test source code is shown in Section 2.1. The web browser support test source code is run in Section 2.2, which shows the web browser support test result.

<script>
