Screen reader accessibility #2696

Closed Sereza7 closed 1 year ago

Sereza7 commented 1 year ago

Hello! When using a screen reader, navigation through a tree is not possible. When going up or down a node, the screen reader will only eventually read something. I think this might be caused by the absence of tabindex changes in the trees.

This issue can be tested on the demo https://www.jstree.com/demo/ . Tested with screen readers such as Orca (Linux) , Jaws and NVDA (Windows).

Some great sources for screen-reader accessibility in hierarchy trees: http://accessibleculture.org/articles/2013/02/not-so-simple-aria-tree-views-and-screen-readers/ https://www.w3.org/WAI/ARIA/apg/patterns/treeview/

Thank you for the report - it is however a duplicate #2498 - I will focus on v.4 now, so accessibility in v3 will remain as is, as all bug reports and feature requests were a mix of contradicting opinions and PRs.

Behaviour with NVDA going through the tree: * Create button
✏ Rename button
Delete button
Search edit has auto complete blank tree view Root 2 not selected 2 of 2 level 1 level 3 One more not selected 1 of 1 tree view level 2 Child 2 not selected collapsed 2 of 2 tree view Child 1 not selected 1 of 2 level 2 tree view level 1 Root 1 not selected collapsed 1 of 2 tree view

When navigating with arrows, the first text, with the content, never has time to be narrated, and in the end, the user can only hear "tree view" when navigating.
