JSON library support many different programming languages.JSON-convert to JavaScript Object The JSON text format is syntactically the same as the code used to create JavaScript objects. Because of this similarity, there is no need for a parser. JavaScript programs can use built-in eval () functions to generate native JavaScript objects using

1,json Module Introduction JSON (JavaScript Object notation) is a lightweight data interchange format. Easy for people to read and write. It is also easy to machine parse and generate. It is based on JavaScript programming Language, Standard ECMA-262 a subset of 3rd Edition-december 1999. JSON uses a completely langua
Object or array. Therefore, a complex Object can be nested. For example, a Person Object contains the name and address objects, which can be expressed as follows: {"Name": "Michael", "address ": { Quot; city quot;: quot; Beijing quot;, quot; street quot;: quot; Chaoyang Road quot;, quot; postcode quot;: 100025} } JavaScript processing JSON data This section describes how to use JSON to rep

For various languages (java/php /. net/javascript). The data format of the data interface can be easily recognized by everyone. Therefore, json/xml is applied. Json is easier to generate
(JSP. You can use JavaScript Object Notation (JSON) to group and cache metadata, and use JavaScript Functions to access metadata to verify user input. When JavaScript contains scattered metadata, you cannot control how much data is evaluated and how much data is passed to the client. All server code snippets will be evaluated and sent to the server. However, when using JSON to cache data, you can complet
