The difference between JSON object to obtain the specified element and JSON.parse () and JSON.stringify () of

Use JSON.parse (param) to achieve

Example:

var param = {

　　 "name": "Joe Smith" ,

　　 "text" : {

　　　　 "Age": "18 is" ,

　　　　 "Sex": "MALE" 

　　} 

} 

var   obj = the JSON.parse (param);   // a character JSON string into JSON object

 

Then, this can be read: console.log (obj.text); == >> {age: "18", sex: "male"}

 

Difference JSON.parse () and JSON.stringify () of

 

1.JSON.parse ( "to be converted arrays").

2.JSON.stringify ( "to be converted arrays").

3. Use a difference.

①.JSON.stringify string is parsed from an object.

②.JSON.parse json is parsed from a string (key-value pairs).

4. If the parameter does not correspond to the time of use, it can not be properly converted.

 

A .JSON.parse () {string parsed from a target json]

 

example:

1.// definition of a string, var data = '{ "name": "goatling"}'.

2.// analysis target, JSON.parse (data).

3. Results are:

name:"goatling"

 

Two .JSON.stringify () [parse the object from a character string]

 

1.var data={name:'goatling'}

2.JSON.stringify(data)

3. Results are:

'{"name":"goatling"}'
