+// +//
+// +//
+//
+// +// ### Specification +// +// TaskLists MUST be contained in a `(div).js-task-list-container`. +// +// TaskList Items SHOULD be an a list (`UL`/`OL`) element. +// +// Task list items MUST match `(input).task-list-item-checkbox` and MUST be +// `disabled` by default. +// +// TaskLists MUST have a `(textarea).js-task-list-field` form element whose +// `value` attribute is the source (Markdown) to be udpated. The source MUST +// follow the syntax guidelines. +// +// TaskList updates trigger `tasklist:change` events. If the change is +// successful, `tasklist:changed` is fired. The change can be canceled. +// +// jQuery is required. +// +// ### Methods +// +// `.taskList('enable')` or `.taskList()` +// +// Enables TaskList updates for the container. +// +// `.taskList('disable')` +// +// Disables TaskList updates for the container. +// +//# ### Events +// +// `tasklist:enabled` +// +// Fired when the TaskList is enabled. +// +// * **Synchronicity** Sync +// * **Bubbles** Yes +// * **Cancelable** No +// * **Target** `.js-task-list-container` +// +// `tasklist:disabled` +// +// Fired when the TaskList is disabled. +// +// * **Synchronicity** Sync +// * **Bubbles** Yes +// * **Cancelable** No +// * **Target** `.js-task-list-container` +// +// `tasklist:change` +// +// Fired before the TaskList item change takes affect. +// +// * **Synchronicity** Sync +// * **Bubbles** Yes +// * **Cancelable** Yes +// * **Target** `.js-task-list-field` +// +// `tasklist:changed` +// +// Fired once the TaskList item change has taken affect. +// +// * **Synchronicity** Sync +// * **Bubbles** Yes +// * **Cancelable** No +// * **Target** `.js-task-list-field` +// +// ### NOTE +// +// Task list checkboxes are rendered as disabled by default because rendered +// user content is cached without regard for the viewer.
