The aria-autocomplete attribute defines if the entering description or content results in the display of a number of predictions from the user’s meant value for a combobox, searchbox, or textbox and how these predictions are displayed. The goal of the attribute is to connect features that provide inline suggestions from user inputs. The ext for completed from the value of the field displays just after the input cursor. A command such as tabbing follows this principle wherein the value being suggested is considered the value if it is taken action by the user itself. In certain conditions wherein a non-specific input element is being proposed to the users, developers can do away with a specific value or assign the aria-autocomplete attribute to “none”. The aria-autocomplete command can be used in elements such as <datalist>. The <datalist> HTML element includes a series of <option> elements that contain submitted options that can be selected from within another control. The aria-autocomplete can be used for ARIA Labels like aria-controls, aria-haspopup, aria-activedescendant, and aria-expanded.
What is the function of the “aria-autocomplete” ARIA Label?
The aria-autocomplete attribute specifies the type of autocompletion interaction paradigm that will be used by a textbook, search box, or combobox when dynamically assisting users with text input. It differentiates between two models: the inline model (aria-autocomplete=inline”), which displays a single estimate value. The list model (aria-autocomplete=”list”), which displays a selection of potential values in a distinct element that appears adjacent to or just below the text input. The aria-autocomplete=”both” is used when the interface displays a list and a projected value.
What are the uses of the “aria-autocomplete” ARIA Label?
Listed below are the uses of the “aria-autocomplete” ARIA Label.
- combobox role: The combobox role designates an element as an input that influences another element, such as a listbox or grid, that can automatically appear to assist the user in setting the value of that input.
- textbox role: The textbook role identifies an element that permits the entry of free-form text. The browser notifies the user’s assistive technology when an accessible textbook event occurs.
- inherits from search box role: The search box role identifies an element as a sort of textbook designed for entering search criteria.
Example Uses of “aria-autocomplete” ARIA Label
Listed below are the example uses of the “aria-autocomplete” ARIA Label.
The aria-autocomplete attribute for assistive technologies merely identifies the type of anticipated behavior for an input element; it does not deliver the functionality. The actual autocompletion function should be implemented with HTML elements or JavaScript. In this case, a page comprises a combobox consisting of a textbook and a dropdown list of user-selectable options. The selected list items become the textbook’s value. As the user navigates through the list using the arrow keys, aria-activedescendant is modified to reflect the attribute of the currently browsed child element.
