我一直在使用eval,它在一个webbrowser中工作,但不能在另一个webbrowser中工作(这些不是您的标准浏览器,而是与其他应用程序集成的浏览器)。在一个我的300多个项目的对象被正确处理。在opther中它处理从256到最后的项目,但跳过前255个! JSON也是正确的。评估的任何替代方案?也许是一个jsonToObject函数。我现在正在写自己的,但是我遇到了主要的时间限制,希望我不必重新发明轮子
任何想法或功能?
非常感谢
到目前为止,我有这个,我打算尝试以反向抛光为基础。不确定它是最有效的,但由于某种原因,它似乎是一个有趣的挑战。我的一部分是折叠到我所拥有的压力,所以我需要现实,并询问是否有任何可以与我分享的方法。
