Category: Properties


The DOM node context originally passed to jQuery(); if none was passed then context will likely be the document.


A string containing the jQuery version number.


Contains flags for the useragent, read from navigator.userAgent. This property was removed in jQuery 1.9 and is available only through the jQuery.migrate plugin. Please try to use feature detection instead.


A Promise-like object (or “thenable”) that resolves when the document is ready.


A collection of properties that represent the presence of different browser features or bugs. Intended for jQuery’s internal use; specific properties may be removed when they are no longer needed internally to improve page startup performance. For your own project’s feature-detection needs, we strongly recommend the use of an external library such as Modernizr instead of dependency on properties in jQuery.support.


The number of elements in the jQuery object.


A selector representing selector passed to jQuery(), if any, when creating the original set.
