# jQuery.isPlainObject()

Check to see if an object is a plain object (created using "{}" or "new Object").

Note: Host objects (or objects used by browser host environments to complete the execution environment of ECMAScript) have a number of inconsistencies which are difficult to robustly feature detect cross-platform. As a result of this, $.isPlainObject() may evaluate inconsistently across browsers in certain instances. An example of this is a test against document.location using $.isPlainObject() as follows:

console.log( $.isPlainObject( document.location ) ); which throws an invalid pointer exception in IE8. With this in mind, it's important to be aware of any of the gotchas involved in using $.isPlainObject() against older browsers. A couple basic examples that do function correctly cross-browser can be found below.
