Cocos2d-x的SprideMonkey的JavaScript与C++的交互 - 单个全局变量操作

js全局变量的操作.

1.修改值.

该例子是说.js里面有个全局变量x.现在把x获取到c++中. 这块是个字符串.

[cpp] jsval x;
JS_GetProperty(sc->getGlobalContext(), sc->getGlobalObject(), "x", &x);
JSString* pS = JS_ValueToString(ScriptingCore::getInstance()->getGlobalContext(), x);
JSStringWrapper pW(pS);
CCLog(pW.get().c_str());

            jsval x;
            JS_GetProperty(sc->getGlobalContext(), sc->getGlobalObject(), "x", &x);
            JSString* pS = JS_ValueToString(ScriptingCore::getInstance()->getGlobalContext(), x);
            JSStringWrapper pW(pS);
            CCLog(pW.get().c_str());

2.获取值.

改例子是说.js里面有个全局变量x.现在通过c++把值给设置成HelloWorld!

[cpp] jsval x = c_string_to_jsval(sc->getGlobalContext(), "HelloWorld!");
JS_SetProperty(sc->getGlobalContext(), sc->getGlobalObject(), "x", &x);

jsval x = c_string_to_jsval(sc->getGlobalContext(), "HelloWorld!");
JS_SetProperty(sc->getGlobalContext(), sc->getGlobalObject(), "x", &x);
待续...复杂的Arry和Object.
