JSON 的两种结构：“名称/值” 对的集合：不同语言中，它被理解成对象（object）、记录（record）、结构（struct）、字典（dictionary）、哈希表（hash table）、有键列表（keyed list）或者关联数组（associative array）。值的有序列表：大部分语言中，它被理解成数组（array）。例如用以下 JSON 数据来描述一个人...
String.prototype.split() 它即可以带一个确定的字符串参数去分割目标字符串,也可以带一个正则表达式参数。 它可以带一个限制的数量,这样可以让最终的结果数组不再包含在这之后的空元素。 String.prototype.substring(): 不再要求第二个索引值大于第一个。 toString(): 现在可以把对象或者数组转换为文字。 break和...
JavaScript dictionaries are converted to Dictionary<string,object>. .NET Framework properties or input parameters that are structures are marshaled by value from a JavaScript object. Only public properties and fields on the target structure are candidates for matching JavaScript properties. If the structu...

To understand what’s going on, we need to better understand the inner workings of JavaScript. Closures are typically implemented by every function object linking to a dictionary-style object representing its lexical scope. If both functions defined insidereplaceThingactually usedpriorThing, it would ...
基本类型值包括"undefined","nul","Boolean","Number","String"(是的,String也是基础类型),除此之外都是引用类型。对于前五种基础类型的互换,应该没有太多要讲的。接下来会重点讲讲引用类型的互换: NSDictionary <--> Object 在上节中,我们把JSContext的globalObject转换成OC对象,发现是NSDictionary类型。要搞...
