JavaScriptObject #

is_refcounted, core, not_builtin_classes

A wrapper class for web native JavaScript objects.

JavaScriptObject is used to interact with JavaScript objects retrieved or created via JavaScriptBridge.get_interface, JavaScriptBridge.create_object, or JavaScriptBridge.create_callback.

extends Node

var _my_js_callback = JavaScriptBridge.create_callback(myCallback) # This reference must be kept
var console = JavaScriptBridge.get_interface("console")

func _init():
    var buf = JavaScriptBridge.create_object("ArrayBuffer", 10) # new ArrayBuffer(10)
    print(buf) # Prints [JavaScriptObject:OBJECT_ID]
    var uint8arr = JavaScriptBridge.create_object("Uint8Array", buf) # new Uint8Array(buf)
    uint8arr[1] = 255
    prints(uint8arr[1], uint8arr.byteLength) # Prints "255 10"

    # Prints "Uint8Array(10) [ 0, 255, 0, 0, 0, 0, 0, 0, 0, 0 ]" in the browser's console.
    console.log(uint8arr)

    # Equivalent of JavaScriptBridge: Array.from(uint8arr).forEach(myCallback)
    JavaScriptBridge.get_interface("Array").from(uint8arr).forEach(_my_js_callback)

func myCallback(args):
    # Will be called with the parameters passed to the "forEach" callback
    # [0, 0, [JavaScriptObject:1173]]
    # [255, 1, [JavaScriptObject:1173]]
    # ...
    # [0, 9, [JavaScriptObject:1180]]
    print(args)
