Intended audience: users, XHTML/HTML coders (using editors or scripting), script developers (PHP, JSP, etc.), CSS coders, Web project managers, and anyone who wants to know whether dirname is supported in browsers.
These tests check whether a dirname attribute passes information about the direction of an input field to the server.
Note that the snapshot summaries of these test results are for released versions of the browsers tested. Versions that are still in development may provide better support for these features. The tests themselves do not test any vendor prefixes.
The tables show results for tests run on the date shown. Above the tables are summaries of the results at that date. The table data may be more up-to-date than the summary. If the tables contain some incorrectly scored tests, or tests that relate to non-released versions of browsers, these are not included in the summary.
