在大部分语言中,它被理解为数组(array)。 这些都是常见的数据结构。事实上大部分现代计算机语言都以某种形式支持它们。这使得一种数据格式在同样基于这些结构的编程语言之间交换成为可能。 有关JSON的更多介绍,访问它的官方网站:http://www.json.org 在JavaScript中使用JSON JSON是JavaScript对象描述符号(object literal...
JSON解析器只认可JSON文本,因此它比较安全: 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...
A JSON object is similar to a JavaScript object. We can also create a JSON array containing many objects, and then we can iterate over this array or use "[]" square brackets to get the desired object. Below is an example of an array of JSON objects: JSON Objects Array Example [ {"n...
JavaScript Object Notation, more commonly known by the acronym JSON, is an open data interchange format that is both human and machine-readable.
JSON建构于两种结构: “名称/值”对的集合(A collection of name/value pairs)。不同的语言中,它被理解为对象(object),纪录(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)。
JSON is a lightweight format for storing and transporting data JSON is often used when data is sent from a server to a web page JSON is "self-describing" and easy to understand JSON Example This example defines an employees object: an array of 3 employee records (objects): ...
The two primary parts that make up JSON are keys and values. Together they make a key/value pair.Key: A key is always a string enclosed in quotation marks. Value: A value can be a string, number, boolean expression, array, or object. Key/Value Pair: A key value pair follows a ...
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 of values. In JSON, array values must be type string, number...
