Learn all about the jQuery function .context.
.context property was deprecated in jQuery 1.10 and is only maintained to the extent needed for supporting
.live() in the jQuery Migrate plugin. It may be removed without notice in a future version.
.live() method for binding event handlers uses this property to determine the root element to use for its event delegation needs.
The value of this property is typically equal to
document, as this is the default context for jQuery objects if none is supplied. The context may differ if, for example, the object was created by searching within an
<iframe> or XML document.
Note that the context property may only apply to the elements originally selected by
jQuery(), as it is possible for the user to add elements to the collection via methods such as
.add() and these may have a different context.
