Types
compositionEvent
The DOM CompositionEvent represents events that occur due to the user indirectly entering text. See CompositionEvent on MDN
type compositionEvent = { type_: WebAPI.EventAPI.eventType, target: Null.t<WebAPI.EventAPI.eventTarget>, currentTarget: Null.t<WebAPI.EventAPI.eventTarget>, eventPhase: int, bubbles: bool, cancelable: bool, defaultPrevented: bool, composed: bool, isTrusted: bool, timeStamp: float, view: Null.t<WebAPI.DOMAPI.window>, detail: int, data: string,}Record fields
type_
Returns the type of event, e.g. "click", "hashchange", or "submit". Read more on MDN
target
Returns the object to which event is dispatched (its target). Read more on MDN
currentTarget
Returns the object whose event listener's callback is currently being invoked. Read more on MDN
eventPhase
Returns the event's phase, which is one of NONE, CAPTURING_PHASE, AT_TARGET, and BUBBLING_PHASE. Read more on MDN
bubbles
Returns true or false depending on how event was initialized. True if event goes through its target's ancestors in reverse tree order, and false otherwise. Read more on MDN
cancelable
Returns true or false depending on how event was initialized. Its return value does not always carry meaning, but true can indicate that part of the operation during which event was dispatched, can be canceled by invoking the preventDefault() method. Read more on MDN
defaultPrevented
Returns true if preventDefault() was invoked successfully to indicate cancelation, and false otherwise. Read more on MDN
composed
Returns true or false depending on how event was initialized. True if event invokes listeners past a ShadowRoot node that is the root of its target, and false otherwise. Read more on MDN
isTrusted
Returns true if event was dispatched by the user agent, and false otherwise. Read more on MDN
timeStamp
Returns the event's timestamp as the number of milliseconds measured relative to the time origin. Read more on MDN

dataTransfer
Used to hold the data that is being dragged during a drag and drop operation. It may hold one or more data items, each of one or more data types. For more information about drag and drop, see HTML Drag and Drop API. See DataTransfer on MDN
type dataTransfer = { mutable dropEffect: string, mutable effectAllowed: string, items: dataTransferItemList, types: array<string>, files: WebAPI.DOMAPI.fileList,}Record fields
dropEffect
Returns the kind of operation that is currently selected. If the kind of operation isn't one of those that is allowed by the effectAllowed attribute, then the operation will fail.
Can be set, to change the selected operation.
The possible values are "none", "copy", "link", and "move". Read more on MDN
effectAllowed
Returns the kinds of operations that are to be allowed.
Can be set (during the dragstart event), to change the allowed operations.
The possible values are "none", "copy", "copyLink", "copyMove", "link", "linkMove", "move", "all", and "uninitialized", Read more on MDN
items
Returns a DataTransferItemList object, with the drag data. Read more on MDN
types
Returns a frozen array listing the formats that were set in the dragstart event. In addition, if any files are being dragged, then one of the types will be the string "Files". Read more on MDN
files
Returns a FileList of the files being dragged, if any. Read more on MDN
Module
