JavaScriptObject is used to interact with JavaScript objects retrieved or created via [method JavaScript.get_interface], [method JavaScript.create_object], or [method JavaScript.create_callback].
|
|
Example:
|
|
[codeblock]
|
|
extends Node
|
|
|
|
var _my_js_callback = JavaScript.create_callback(self, "myCallback") # This reference must be kept
|
|
var console = JavaScript.get_interface("console")
|
|
|
|
func _init():
|
|
var buf = JavaScript.create_object("ArrayBuffer", 10) # new ArrayBuffer(10)
|
|
print(buf) # prints [JavaScriptObject:OBJECT_ID]
|
|
var uint8arr = JavaScript.create_object("Uint8Array", buf) # new Uint8Array(buf)
|
|
uint8arr[1] = 255
|
|
prints(uint8arr[1], uint8arr.byteLength) # prints 255 10
|
|
console.log(uint8arr) # prints in browser console "Uint8Array(10) [ 0, 255, 0, 0, 0, 0, 0, 0, 0, 0 ]"
|
|
|
|
# Equivalent of JavaScript: Array.from(uint8arr).forEach(myCallback)
|
|
JavaScript.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)
|
|
[/codeblock]
