• 32 try console.log(JSON.stringify(data)); – chridam Commented Jan 26, 2015 at 11:47
• 5 Use JSON.stringify(data) to convert it into string ang then try to print. – Sanjeev Singh Commented Jan 26, 2015 at 11:48

• console.log(JSON.stringify(data)); is the simplest answer, but if you want something more fancy you can use console-log-json from the NPM repository: npmjs.com/package/console-log-json – 7wp Commented Jul 13, 2022 at 15:24

console.log(JSON.stringify(data)) will do what you need. I'm assuming that you're using jQuery based on your code.

If you're wanting those two particular values, you can just access those and pass them to log.

console.log(data.input_data['quantity-row_122']); 
console.log(data.input_data['price-row_122']); 

I used '%j' option in console.log to print JSON objects

console.log("%j", jsonObj);

To output an object to the console, you have to stringify the object first:

success:function(data){
     console.log(JSON.stringify(data));
}

I usually do like this:

console.log(JSON.stringify(data, undefined, 4));

{"success":true,"input_data":{"quantity-row_122":"1","price-row_122":" 35.1 "}}

console.dir() will do what you need. It will give you a hierarchical structure of the data.

success:function(data){
     console.dir(data);
}

like so

> Object
  > input_data: Object
      price-row_122: " 35.1 "
      quantity-row_122: "1"
    success: true

I don't think you need console.log(JSON.stringify(data)).

To get the data you can do this without stringify:

console.log(data.success); // true
console.log(data.input_data['quantity-row_122']) // "1"
console.log(data.input_data['price-row_122']) // " 35.1 "

Note

The value from input_data Object will be typeof "1": String, but you can convert to number(Int or Float) using ParseInt or ParseFloat, like so:

 typeof parseFloat(data.input_data['price-row_122'], 10) // "number"
 parseFloat(data.input_data['price-row_122'], 10) // 35.1

If you just want to print object then

console.log(JSON.stringify(data)); //this will convert json to string;

If you want to access value of field in object then use

console.log(data.input_data);

You can also use util library:

const util = require("util")

> myObject = {1:2, 3:{5:{6:{7:8}}}}
{ '1': 2, '3': { '5': { '6': [Object] } } }

> util.inspect(myObject, {showHidden: true, depth: null})
"{\n  '1': 2,\n  '3': { '5': { '6': { '7': 8 } } }\n}"

> JSON.stringify(myObject)
'{"1":2,"3":{"5":{"6":{"7":8}}}}'

This is an old post but I'm chiming in because (as Narem briefly mentioned) a few of the printf-like features are available with the console.log formatters. In the case of the question, you can benefit from the string, number or json formatters for your data.

Examples:

console.log("Quantity %s, Price: %d", data.quantity-row_122, data.price-row_122);
console.log("Quantity and Price Data %j", data);

Object

input_data: Object price-row_122: " 35.1 " quantity-row_122: "1" success: true
