JSON supports several data types, including the following: Objects. A JSON object data type is a set of name or value pairs inserted between {} (curly braces). The keys must be strings and separated by a comma and should be unique. Arrays. An array data type is an ordered collection ...
var myObject = myJSONtext.parseJSON(); 而JSON的字符串转换器(stringifier)则作相反的工作,它将JavaScript数据结构转换为JSON文本。JSON是不支持循环数据结构的,所以注意不能把循环的结构交给字符串转换器。 var myJSONText = myObject.toJSONString(); 这里是JSON官方网站提供的一个开源的JSON解析器和字符串转换...

JSON is a text-based data exchange language that usually appears in two forms: as a JSON object and as a JSON array. A JSON object consists of key-value pairs (“Data field”: “Value”) while a JSON array represents an ordered list of values (“Data field1”: “Value1”, “Data ...

JSON能够描述四种简单的类型(字符串、数字、布尔值及null)和两种结构化类型(对象及数组)。 字符串(string)是零个或多个Unicode字符的序列。 对象(object)是无次序的零个或多个名/值(name/value)对的集合,这里的name是string类型,value则可以是string、number、boolean、null、object或array类型。
