A wrapper class for web native JavaScript objects.

Description

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)
