JSONstands forJavaScript Object Notation. JSON is a human and machine-readable format to represent data asStructured Data. JSON is used primarily to transfer data from one computer to another or even between different programs on the same computer. To visualize JSON, let us say that we want to...
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...
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 Booleans Array Example [true, true, false, false, true] JSON Array of Objects 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....
JavaScript Object Notation, more commonly known by the acronym JSON, is an open data interchange format that is both human and machine-readable.
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): ...
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)。
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, ...
JSON (JavaScriptObjectNotation) is a lightweight data-interchange format that is easy for humans to read and write, and for machines to parse and generate. What does JSON do? JSON’s human-readable text transmits data objects consisting of attribute-value pairs and array data types. It was ...
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。
