I want to parse this JSON data to an array using JavaScript or Java And I need full_name,brand & MRP of products.

How to do it please help?

This json is not well formatted, anyway in 10 seconds you can find plenty of resources on stackoverflow, like this: stackoverflow.com/questions/1688099/converting-json-to-java — Paolof76

In javascript you can do that:

var jsonText = '[{"name":"Message", "data": [] ... // jsonText is the string with the json 
var obj = JSON.parse(jsonText);

In java you can represent your json as a Map.

String json = ...
ObjectMapper mapper = new ObjectMapper();
Map<String,Object> map = mapper.readValue(json, Map.class);

But this JSONData is coming from URL And how can i display this??

Davide Lorenzo MARINO Over a year ago

You have to convert it to a string. If it comes from url, from the body of an ajax call or just from a string in your code it doesn't change.

var json=xmlhttp.responseText; obj=jQuery.parseJSON(json); How to print after getting response from AJAX?

Now it is an object. You can place a breakpoint on your javascript code and inspect it with the integrated debugger on your browser (or printing it with console.log function).

suppose you have URL like var url = http://localhost?jsonData=[...]

In javascript, u can get jsonData like var jsonData = url.split("=")[1];

But it is of string type. To parse it to JSON write jsonData = JSON.parse(jsonData)

Now to get an array of Strings which you want to display, var printData = jsonData.map(function(jsonObj){ return jsonobj.title + jsonobj.brand.name + jsonObj.price; })

Now you can see printData in console using below code console.log(JSON.stringify(printData));
