TaskController: TaskController() constructor
Limited availability
This feature is not Baseline because it does not work in some of the most widely-used browsers.
The TaskController() constructor creates a new TaskController object, optionally setting the initial priority of its associated signal.
If no priority is set, the signal priority defaults to user-visible
Syntax
js
new TaskController()
new TaskController(options)
Parameters
Examples
This code shows how to construct a task controller that has a signal with default priority (user-visible).
js
const controller = new TaskController();
To construct a task controller that has a specific signal priority, pass the priority as a property of the optional argument.
js
controller2 = new TaskController({ priority: "user-blocking" });
