Web 原生 JavaScript 对象的封装类。

.. rst-class:: classref-introduction-group

描述
----

JavaScriptObject 用于与通过 :ref:`JavaScriptBridge.get_interface<class_JavaScriptBridge_method_get_interface>`\ 、\ :ref:`JavaScriptBridge.create_object<class_JavaScriptBridge_method_create_object>` 或 :ref:`JavaScriptBridge.create_callback<class_JavaScriptBridge_method_create_callback>` 检索或创建的 JavaScript 对象进行交互。

\ **示例：**\ 

::

    extends Node
    
    var _my_js_callback = JavaScriptBridge.create_callback(myCallback) # 必须保留该引用
    var console = JavaScriptBridge.get_interface("console")
    
    func _init():
        var buf = JavaScriptBridge.create_object("ArrayBuffer", 10) # 新建 ArrayBuffer(10)
        print(buf) # 输出 [JavaScriptObject:OBJECT_ID]
        var uint8arr = JavaScriptBridge.create_object("Uint8Array", buf) # 新建 Uint8Array(buf)
        uint8arr[1] = 255
        prints(uint8arr[1], uint8arr.byteLength) # 输出 255 10
        console.log(uint8arr) # prints in browser console "Uint8Array(10) [ 0, 255, 0, 0, 0, 0, 0, 0, 0, 0 ]"
    
        # 等效于 JavaScriptBridge: Array.from(uint8arr).forEach(myCallback)
        JavaScriptBridge.get_interface("Array").from(uint8arr).forEach(_my_js_callback)
    
    func myCallback(args):
        # 将使用传递给“forEach”回调的参数调用
        # [0, 0, [JavaScriptObject:1173]]
        # [255, 1, [JavaScriptObject:1173]]
        # ...
        # [0, 9, [JavaScriptObject:1180]]
        print(args)
