objectThe object that will be checked to see if it's a plain 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. Some basic example of use-cases that do function correctly cross-browser can be found below.
Example:
Check an object to see if it's a plain object.
jQuery.isPlainObject({}) // true
jQuery.isPlainObject("test") // false
