如何使用jQuery解析JSON

Question

This is my JSON output from server side:

[{"id":1,"name":"Information Technology"},
 {"id":2,"name":"mechanical engineering"},
 {"id":3,"name":"computer science"},
 {"id":4,"name":"electronics and communication"}] 

How can I parse this in my client side using jQuery?

Answer 1

IF you're getting it through jquery's getJson method, your object will be automatically be parsed.
A second option will be to parse it yourself through the parseJSON jquery method ( http://api.jquery.com/jQuery.parseJSON/ ) or through the browser's native implementation of JSON parsing : JSON.parse .
The last alternative would be to evaluate the object using eval , but that isn't recommended.

Answer 2

正如您专门要求使用JQuery的解决方案一样，您应该查看JQuery文档，这是他们的JSON解析文档Jquery.parseJSON

Answer 3

使用jQuery的

var theObject = jQuery.parseJSON(jsonString);

Answer 4

try this

for (var idx in json_object){
 console.log(json_object[idx].id, json_object[idx].name);
}
