Creates a reference to a [Callable] that can be used as a callback by JavaScript. The reference must be kept until the callback happens, or it won't be called at all. See [JavaScriptObject] for usage.

Returns an interface to a JavaScript object that can be used by scripts. The [code]interface[/code] must be a valid property of the JavaScript [code]window[/code]. The callback must accept a single [Array] argument, which will contain the JavaScript [code]arguments[/code]. See [JavaScriptObject] for usage.

A wrapper class for native JavaScript objects.

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]
