Rhino - 将 javascript 对象传递给 java [英] Rhino - Passing a javascript object to java

问题描述

我对 Rhino 很陌生，我的问题是如何实现以下目标，

Im quite new to Rhino and my question is around how to achieve the following,

假设我有一个 javascript 对象，它遵循以下类似的内容，我可以在 java 中使用它.

Say I have a javascript object that follows something like the following that I can consume within java.

var myObject = new Object();
myObject.string1 = "Hello";
myObject.string2 = "World";
myObject.int1 = 1;

但是如果它是动态的，我如何在 java 中使用它.例如如果您决定在 javascript 中向此对象动态添加更多成员.这是可行的吗?我的猜测是在 java 中定义的类必须考虑所有可能的成员才能做到这一点?

But how do I consume this within java if its dynamic. For .e.g. if you decide to add few more members dynamically to this object within javascript. Is this doable ? My guess is the class defined within java will have to take all the possible members into account to do this ?

希望我已经解释了我试图正确实现的目标.

Hopefully I have explained what im trying to achieve correctly.

推荐答案

JavaScript 对象，当您在 Java 中访问它们时，本质上都是同一个类:ScriptableObject，它实现了 Scriptable 接口 (GitHub 源代码).还有一些其他类用于函数和其他专用对象.

JavaScript objects, when you access them in Java, are all essentially the same class: ScriptableObject which implements the Scriptable interface (GitHub source). There are a few other classes for functions and other specialized objects.

Scriptable 接口包括 get、has 和 put 等方法，大致对应于 JavaScript 中的 myObject.string1、myObject.hasOwnProperty("string1") 和 myObject.string1 = "Hello".ScriptableObject 类添加了一些其他有用的方法来定义属性等.

The Scriptable interface includes methods like get, has, and put that correspond roughly to myObject.string1, myObject.hasOwnProperty("string1"), and myObject.string1 = "Hello" in JavaScript. The ScriptableObject class adds some other useful methods for defining properties, etc.
