Selecting DOM Elements Within a Specified Context - J Query

You need a reference to a single DOM element or a set of DOM elements in the context of another DOM element or document in order to operate on the element(s) using jQuery methods.


The jQuery function when passed a CSS expression will also accept a second parameter that tells the jQuery function to which context it should search for the DOM elements based on the expression.
