DOM binding

This is a partial binding to the DOM Core API.

DOM objects

Sourceclass type 'node nodeList = object ... end

Specification of NodeList objects.

Sourcetype nodeType =
  1. | OTHER
  2. | ELEMENT
  3. | ATTRIBUTE
  4. | TEXT
  5. | CDATA_SECTION
  6. | ENTITY_REFERENCE
  7. | ENTITY
  8. | PROCESSING_INSTRUCTION
  9. | COMMENT
  10. | DOCUMENT
  11. | DOCUMENT_TYPE
  12. | DOCUMENT_FRAGMENT
  13. | NOTATION
Sourcemodule DocumentPosition : sig ... end
Sourceclass type node = object ... end

Specification of Node objects.

Sourceclass type attr = object ... end

Specification of NamedNodeMap objects.

Sourceclass type element = object ... end

Specification of Element objects.

Sourceclass type characterData = object ... end

Helper functions

Sourceval insertBefore : node Js.t -> node Js.t -> node Js.t Js.opt -> unit

insertBefore p n c inserts node n as child of node p, just before node c, or as last child if p is empty. The expression insertBefore n c p behave the same as p##insertBefore n c but avoid the need of coercing the different objects to node t.

Sourceval replaceChild : node Js.t -> node Js.t -> node Js.t -> unit

The expression replaceChild p n c behave the same as p##replaceChild n c (replace c by n in p) but avoid the need of coercing the different objects to node t.

Sourceval removeChild : node Js.t -> node Js.t -> unit

The expression removeChild n c behave the same as n##removeChild c (remove c from n) but avoid the need of coercing the different objects to node t.

Sourceval appendChild : node Js.t -> node Js.t -> unit

The expression appendChild n c behave the same as n##appendChild c (appends c to n) but avoid the need of coercing the different objects to node t.

Sourceval list_of_nodeList : 'a nodeList Js.t -> 'a Js.t list
Sourcetype node_type =
  1. | Element of element Js.t
  2. | Attr of attr Js.t
  3. | Text of text Js.t
  4. | Other of node Js.t
Sourceval nodeType : node Js.t -> node_type
Sourcemodule CoerceTo : sig ... end

Events

Sourcetype (-'a, -'b) event_listener

The type of event listener functions. The first type parameter 'a is the type of the target object; the second parameter 'b is the type of the event object.

Sourceclass type 'a event = object ... end
Sourceclass type ['a, 'b] customEvent = object ... end

Event handlers

Sourceval no_handler : ('a, 'b) event_listener

Void event handler (Javascript null value).

Sourceval handler : ('e event Js.t as 'b -> bool Js.t) -> ('a, 'b) event_listener

Create an event handler that invokes the provided function. If the handler returns false, the default action is prevented.

Sourceval full_handler : ('a -> 'e event Js.t as 'b -> bool Js.t) -> ('a, 'b) event_listener

Create an event handler that invokes the provided function. The event target (implicit parameter this) is also passed as argument to the function.

Sourceval invoke_handler : ('a, 'b) event_listener -> 'a -> 'b -> bool Js.t

Invoke an existing handler. Useful to chain event handlers.

Sourceval eventTarget : < .. > as 'a event Js.t -> 'a Js.t

Returns which object is the target of this event. It raises Not_found in case there is no target (if the event has not been triggered yet)

Sourcetype event_listener_id
Sourcemodule Event : sig ... end
Sourceval addEventListenerWithOptions : < .. > Js.t as 'a -> 'b Event.typ -> ?capture:bool Js.t -> ?once:bool Js.t -> ?passive:bool Js.t -> ('a, 'b) event_listener -> event_listener_id

Add an event listener. This function matches the option-object variant of the addEventListener DOM method, except that it returns an id for removing the listener.

Sourceval addEventListener : < .. > Js.t as 'a -> 'b Event.typ -> ('a, 'b) event_listener -> bool Js.t -> event_listener_id

Add an event listener. This function matches the useCapture boolean variant of the addEventListener DOM method, except that it returns an id for removing the listener.

Sourceval removeEventListener : event_listener_id -> unit

Remove the given event listener.

Sourceval preventDefault : 'a event Js.t -> unit

Call this to prevent the default handler for the event. To stop propagation of the event, call Dom_html.stopPropagation.

Sourceval createCustomEvent : ?bubbles:bool -> ?cancelable:bool -> ?detail:'b -> ['a, 'b] customEvent Js.t Event.typ -> ('a, 'b) customEvent Js.t

Create a custom event of given type.
