How to Display a JavaScript Object
Topic: JavaScript / jQueryPrev|Next
Answer: Use console.log() or JSON.stringify() Method
You can use the console.log() method, if you simply wants to know what's inside an object for debugging purpose. This method will print the object in browser console.
Example
Try this code »// Sample object
var obj = {name: "John", age: 28, gender: "Male"};
// Printing object in console
console.log(obj);If you open the browser console you'll see the output that looks something like this figure.
To open the dedicated Console panel: Press Ctrl+Shift+J (Windows / Linux) or Cmd+Opt+J (Mac).
Alternatively, you can also use the JSON.stringify() method to print the object either on a web page or browser console. Let's try out the following example and see how it works:
Example
Try this code »// Sample object
var obj = {name: "John", age: 28, gender: "Male"};
// Converting object to JSON string
var str = JSON.stringify(obj);
// Printing the string
document.write(str);
console.log(str);For nicely indented output, you can optinally pass replacer and space parameters, as shown below:
Example
Try this code »// Sample object
var obj = {name: "John", age: 28, gender: "Male"};
// Converting object to JSON string
var str = JSON.stringify(obj, null, 4); // indented with 4 spaces
// Printing the string
document.getElementById("output").innerHTML = str;
console.log(str);See the tutorial on JavaScript Objects to learn more about creating and manipulating objects.
