Print content of JavaScript object? [duplicate]

Typically if we just use alert(object); it will show as [object Object]. How to print all the content parameters of an object in JavaScript?

This will give you very nice output with an indented JSON object using JSON.stringify:

alert(JSON.stringify(YOUR_OBJECT_HERE, null, 4));

The second argument (replacer) alters the contents of the string before returning it.

The third argument (space) specifies how many spaces to use as white space for readability.

JSON.stringify documentation here.
