![]() ![]() The Accessible Name Guidance by Role section lists naming requirements and guidelines for every ARIA role.Īn accessible description is also an author-provided string that is rendered by assistive technologies.Īuthors supply a description when there is a need to associate additional information with an element, such as instructions or format requirements for an input field.Īssistive technologies present names differently from descriptions.įor instance, screen readers typically announce the name and role of an element first, e.g., a button named Mute Conversationcould be spoken as Mute Conversation button. ![]() Many other elements can be named, but whether a name will enhance the accessible experience is determined by various characteristics of the surrounding context.įinally, there are some elements where providing an accessible name is technically possible but not advisable. ![]() In addition dialogs and some structural containers, such as tables and regions, are required to have a name. Distinguish the element from other elements on the page.īoth the WAI-ARIA specification and WCAG require all focusable, interactive elements to have an accessible name.Convey the purpose or intent of the element.What ARE Accessible Names and Descriptions?Īn accessible name is a short string, typically 1 to 3 words, that authors associate with an element to provide users of assistive technologies with a label for the element.įor example, an input field might have an accessible name of "User ID" or a button might be named "Submit".Īn accessible name serves two primary purposes for users of assistive technologies, such as screen readers: Describing tables and figures with captions.Describing by referencing content with aria-describedby.Fallback names derived from titles and placeholders.Naming tables and figures with captions.Naming fieldsets with the legend element.Naming form controls with the label element.Naming by referencing content with aria-labelledby.Naming with a string attribute via aria-label.It also guides authors in the use of the following naming and describing techniques and WAI-ARIA properties: To help authors effectively provide accessible names and descriptions, this section explains their purpose, when authors need to provide them, how browsers assemble them, and rules for coding and composing them. While doing so is straightforward for most elements, technical mistakes that can completely block users of assistive technologies are easy to make and unfortunately common. Mtext(as.character(names(X)), 3, padj=-4.Providing elements with accessible names, and where appropriate, accessible descriptions, is one of the most important responsibilities authors have when developing accessible web experiences. L2 <- lapply(WORDS, function(x) as.ame(table(x), stringsAsFactors = FALSE)) So an answer of names(LIST) is not correct either.ĮDIT: I added code for more context to the problem x <- c("yes", "no", "maybe", "no", "no", "yes") As I come to each ame I want to include the name of the ame as the title. Just for context I am plotting a series of data frames that are stored in a list. Names(LIST) is not correct because it returns "A" and "B". How do I grab the name of just one object from the list? As in: LIST <- list(A=1:5, B=1:10) ![]()
