我现在看教程。有两种获取对像的方法。
可是我用第一种可以获取到。用第二种一直为空，
我想问一下。用第二种，需要怎么的设置。或是要求。因为我现在看到其它的绑定全都用第二个方法。
而且用第二种方法。那这个函数js_proxy_t * p = jsb_get_native_proxy(this);因该也起到作用的。

这是绑定的代码。
急求解，。。。。。
看下的构造函数里就知道了，你用JS_GetPrivate可以是因为你JS_SetPrivate了，这是给js对象设置一个你自己的私有数据的指针,用这种方式你还需要在finalize钩子函数里自己清理掉内存 https://developer.mozilla.org/en-US/docs/Mozilla/Projects/SpiderMonkey/JSAPI_reference/JS_SetPrivate
jsb_get_js_proxy不行是因为你没有创建这一个proxy对象，使用jsb_new_proxy，具体方法看看自动引擎里自动生成的代码里constructor的写法

照着引擎里自动生成的constructor写，把类名神马的改一下应该就好了
好的。谢谢
官方的教程那个自动绑定。写的莫名其妙。怎么都不懂。只好手动了。
