JavaScript Feature Reference: getAttribute()
Method Web Browser Support Test
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 getAttribute()
method. 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 getAttribute()
method, the testing is stopped and the implementation test reports: Fail (no support): The web browser does not recognize the JavaScript
getAttribute()
method. The web browser does not support the JavaScript getAttribute()
method.
If the web browser recognizes the JavaScript getAttribute()
method, the capability test is run. The capability test determines if the web browser's implementation of the JavaScript getAttribute()
method includes support for at least one getAttribute()
method 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 getAttribute()
method includes support for the tested capability, the capability test reports: Pass (at least partial/possibly full support): The web browser recognizes the JavaScript
If the web browser's implementation of the JavaScript getAttribute()
method, and supports at least one getAttribute()
method capability. The web browser at least partially/possibly fully supports the JavaScript getAttribute()
method. Positive determination of full web browser support is beyond the scope of this test.getAttribute()
method does not include support for the tested capability, the capability test reports: Pass/Fail (partial support): The web browser recognizes the JavaScript
getAttribute()
method, but does not support at least one getAttribute()
method capability. The web browser partially supports the JavaScript getAttribute()
method.
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.
