pretty-print JSON using JavaScript

Question

How can I display JSON in an easy-to-read (for human readers) format? I\'m looking primarily for indentation and whitespace, with perhaps even colors / font-styles / etc.

Answer 1

var jsonObj = {"streetLabel": "Avenue Anatole France", "city": "Paris 07",  "postalCode": "75007", "countryCode": "FRA",  "countryLabel": "France" };

document.getElementById("result-before").innerHTML = JSON.stringify(jsonObj);

In case of displaying in HTML, you should to add a balise

document.getElementById("result-after").innerHTML = "
"+JSON.stringify(jsonObj,undefined, 2) +"
"

Example:

var jsonObj = {"streetLabel": "Avenue Anatole France", "city": "Paris 07",  "postalCode": "75007", "countryCode": "FRA",  "countryLabel": "France" };

document.getElementById("result-before").innerHTML = JSON.stringify(jsonObj);

document.getElementById("result-after").innerHTML = "
"+JSON.stringify(jsonObj,undefined, 2) +"
"

div { float:left; clear:both; margin: 1em 0; }
