Module Js.Unsafe

module Unsafe: sig .. end
Unsafe Javascript operations

type any 
Top type. Used for putting values of different types in a same array.
val inject : 'a -> any
Coercion to top type.
val coerce : 'a Js.t -> 'b Js.t
Unsafe coercion between to Javascript objects.
val get : 'a -> 'b -> 'c
Get the value of an object property. The expression get o s returns the value of property s of object o.
val set : 'a -> 'b -> 'c -> unit
Set an object property. The expression set o s v set the property s of object o to value v.
val delete : 'a -> 'b -> unit
Delete an object property. The expression delete o s deletes property s of object o.
val call : 'a -> 'b -> any array -> 'c
Performs a Javascript function call. The expression call f o a calls the Javascript function f with the arguments given by the array a, and binding this to o.
val fun_call : 'a -> any array -> 'b
Performs a Javascript function call. The expression fun_call f a calls the Javascript function f with the arguments given by the array a.
val meth_call : 'a -> string -> any array -> 'b
Performs a Javascript method call. The expression meth_call o m a calls the Javascript method m of object o with the arguments given by the array a.
val new_obj : 'a -> any array -> 'b
Create a Javascript object. The expression new_obj c a creates a Javascript object with constructor c using the arguments given by the array a.
val obj : (string * any) array -> 'a
Creates a Javascript literal object. The expression obj a creates a Javascript object whose fields are given by the array a
val pure_expr : (unit -> 'a) -> 'a
Asserts that an expression is pure, and can therefore be optimized away by the compiler if unused.
val eval_string : string -> 'a
Evaluate Javascript code
val js_expr : string -> 'a
js_expr e will parse the JavaScript expression e if e is available at compile time or will failback to a runtime evaluation. See eval_string
val pure_js_expr : string -> 'a
pure_js_expr str behaves like pure_expr (fun () -> js_expr str).
val global : < .. > Js.t
Javascript global object
val callback : ('a -> 'b) -> ('c, 'a -> 'b) Js.meth_callback
Wrap an OCaml function so that it can be invoked from Javascript. Contrary to Js.wrap_callback, partial application and over-application are not supported: missing arguments will be set to undefined and extra arguments are lost.
val meth_callback : ('b -> 'a) -> ('b, 'a) Js.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. Contrary to Js.wrap_meth_callback, partial application and over-application is not supported: missing arguments will be set to undefined and extra arguments are lost.

Deprecated functions.


val variable : string -> 'a
Access a Javascript variable. variable "foo" will return the current value of variable foo.
