null
and undefined
values.type +'a opt = 'a Js_of_ocaml.Js.opt
Type of possibly null values.
type +'a optdef = 'a Js_of_ocaml.Js.optdef
Type of possibly undefined values.
val null : 'a opt
The null
value.
val some : 'a -> 'a opt
Consider a value into a possibly null value.
val undefined : 'a optdef
The undefined
value
val def : 'a -> 'a optdef
Consider a value into a possibly undefined value.
module type OPT = Js_of_ocaml.Js.OPT
Signatures of a set of standard functions for manipulating optional values.
module Opt = Js_of_ocaml.Js.Opt
Standard functions for manipulating possibly null values.
module Optdef = Js_of_ocaml.Js.Optdef
Standard functions for manipulating possibly undefined values.
type +'a t = 'a Js_of_ocaml.Js.t
Type of Javascript objects. The type parameter is used to specify more precisely an object.
type +'a meth = 'a Js_of_ocaml.Js.meth
Type used to specify method types: a Javascript object <m : t1 -> t2 -> ... -> tn -> t Js.meth> Js.t
has a Javascript method m
expecting n arguments of types t1
to tn
and returns a value of type t
.
type +'a gen_prop = 'a Js_of_ocaml.Js.gen_prop
Type used to specify the properties of Javascript objects. In practice you should rarely need this type directly, but should rather use the type abbreviations below instead.
type 'a readonly_prop = < get : 'a > gen_prop
Type of read-only properties: a Javascript object <p : t Js.readonly_prop> Js.t
has a read-only property p
of type t
.
type 'a writeonly_prop = < set : 'a -> unit > gen_prop
Type of write-only properties: a Javascript object <p : t Js.writeonly_prop> Js.t
has a write-only property p
of type t
.
type 'a prop = < get : 'a ; set : 'a -> unit > gen_prop
Type of read/write properties: a Javascript object <p : t Js.writeonly_prop> Js.t
has a read/write property p
of type t
.
Type of read/write properties that may be undefined: you can set them to a value of some type t
, but if you read them, you will get a value of type t optdef
(that may be undefined
).
type +'a constr = 'a Js_of_ocaml.Js.constr
A value of type (t1 -> ... -> tn -> t Js.t) Js.constr
is a Javascript constructor expecting n arguments of types t1
to tn
and returning a Javascript object of type t Js.t
. Use the syntax extension new%js c e1 ... en
to build an object using constructor c
and arguments e1
to en
.
type (-'a, +'b) meth_callback = ('a, 'b) Js_of_ocaml.Js.meth_callback
Type of callback functions. A function of type (u, t1 -> ... -> tn -> t) meth_callback
can be called from Javascript with this
bound to a value of type u
and up to n arguments of types t1
to tn
. The system takes care of currification, so less than n arguments can be provided. As a special case, a callback of type (t, unit -> t) meth_callback
can be called from Javascript with no argument. It will behave as if it was called with a single argument of type unit
.
type 'a callback = (unit, 'a) meth_callback
Type of callback functions intended to be called without a meaningful this
implicit parameter.
val wrap_callback : ('a -> 'b) -> ('c, 'a -> 'b) meth_callback
Wrap an OCaml function so that it can be invoked from Javascript.
val wrap_meth_callback : ('b -> 'a) -> ('b, 'a) meth_callback
Wrap an OCaml function so that it can be invoked from Javascript. The first parameter of the function will be bound to the value of the this
implicit parameter.
val _true : bool t
Javascript true
boolean.
val _false : bool t
Javascript false
boolean.
type match_result_handle = Js_of_ocaml.Js.match_result_handle
A handle to a match result. Use function Js.match_result
to get the corresponding MatchResult
object. (This type is used to resolved the mutual dependency between string and array type definitions.)
type string_array = Js_of_ocaml.Js.string_array
Opaque type for string arrays. You can get the actual Array
object using function Js.str_array
. (This type is used to resolved the mutual dependency between string and array type definitions.)
type normalization = Js_of_ocaml.Js.normalization
Opaque type for Unicode normalization forms.
val nfd : normalization t
Canonical Decomposition
val nfc : normalization t
Canonical Decomposition, followed by Canonical Composition
val nfkd : normalization t
Compatibility Decomposition
val nfkc : normalization t
Compatibility Decomposition, followed by Canonical Composition

, function f
is called.
Apply a possibly failing coercion function. coerce_opt v c f
attempts to apply coercion c
to value v

is null
or the coercion returns null
, function f
is called. Typical usage is the following:
Js.coerce_opt (Dom_html.document##getElementById id)
Dom_html.CoerceTo.div (fun _ -> assert false)
Tests whether a Javascript object is an instance of a given class.
Invokes any available debugging functionality. If no debugging functionality is available, it has no effect. In practice, it will insert a "debugger;" statement in the generated javascript.

module Unsafe = Js_of_ocaml.Js.Unsafe
Unsafe Javascript operations
Attach a JavasScript error to an OCaml exception. if force = false
and a JavasScript error is already attached, it will do nothing. This function is useful to store and retrieve information about JavaScript stack traces.
Attaching JavasScript errors will happen automatically when compiling with --enable with-js-error
.
Extract a JavaScript error attached to an OCaml exception, if any. This is useful to inspect an eventual stack strace, especially when sourcemap is enabled.
The Error
exception wrap javascript exceptions when caught by OCaml code. In case the javascript exception is not an instance of javascript Error
, it will be serialized and wrapped into a Failure
exception.
