Mar 03, 2019 The JSON.stringify method converts a JavaScript object or value to a JSON string, optionally replacing values if a replacer function is specified or optionally including only the specified properties if a replacer array is specified. Javascript JSON: Objects. Earlier, JSON parsers did a bit more than what JavaScript eval functions could do, i.e parse, interpret and return the data as JavaScript objects and arrays. But now JSON object has two methods: stringify and parse stringify: To serialize JavaScript objects into a JSON string. Serialize JavaScript. Serialize JavaScript to a superset of JSON that includes regular expressions, dates and functions. The code in this package began its life as an internal module to express-state. To expand its usefulness, it now lives as serialize-javascript — an independent package on npm. Old ps2 games.

Javascript JSON: Parsing and Serialization
The quick popularity of JSON can be attributed to the reason that data could be parsed into an usable object very easily using JSON.
Parsing data using XML was bit difficult, as the data has to be parsed into the DOM document, making the extraction a bit of a cumbersome exercise Winamp old version apk.
Hence, elimination of extra method calls is one of the prime reasons of incredible popularity of JSON with JavaScript webdevelopers
Javascript JSON: Objects
Earlier, JSON parsers did a bit more than what JavaScript eval() functions could do, i.e parse, interpret and return the data as JavaScript objects and arrays.
But now JSON object has two methods : stringify() and parse()
stringify() : To serialize JavaScript objects into a JSON string.
parse() : To parse JSON into a native JavaScript value.
The demo below serializes a JavaScript object into a JSON string by making use of JSON.stringify() and stores the value in jsonString
The JSON string can be passed directly into JSON.parse() to create an appropriate JavaScript value.

Example: JSON Syntax JSON Object.
-->JSON (JavaScript Object Notation) is an efficient data encoding format that enables fast exchanges of small amounts of data between client browsers and AJAX-enabled Web services.
This article demonstrates how to serialize .NET type objects into JSON-encoded data and then deserialize data in the JSON format back into instances of .NET types. This example uses a data contract to demonstrate serialization and deserialization of a user-defined
Person
Free touch screen games download. type and uses DataContractJsonSerializer.Normally, JSON serialization and deserialization are handled automatically by Windows Communication Foundation (WCF) when you use data contract types in service operations that are exposed over AJAX-enabled endpoints. However, in some cases you may need to work with JSON data directly.
Note
This article is about DataContractJsonSerializer. For most scenarios that involve serializing and deserializing JSON, we recommend the tools in the System.Text.Json namespace.
This article is based on the DataContractJsonSerializer sample.
To define the data contract for a Person type
- Define the data contract for
Person
by attaching the DataContractAttribute to the class and DataMemberAttribute attribute to the members you want to serialize. For more information about data contracts, see Designing service contracts.
To serialize an instance of type Person to JSON
Note
If an error occurs during serialization of an outgoing reply on the server or for some other reason, it may not get returned to the client as a fault.
- Create an instance of the
Person
type. - Serialize the
Person
object to a memory stream by using the DataContractJsonSerializer. - Use the WriteObject method to write JSON data to the stream.
- Show the JSON output.
To deserialize an instance of type Person from JSON
- Deserialize the JSON-encoded data into a new instance of
Person
by using the ReadObject method of the DataContractJsonSerializer. - Show the results.

The JSON serializer throws a serialization exception for data contracts that have multiple members with the same name, as shown in the following sample code.
