Description: Get the immediately following sibling of each element in the set of matched elements, optionally filtered by a selector.
selectorA string containing a selector expression to match elements against.
Given a jQuery object that represents a set of DOM elements, the .next() method allows us to search through the successors of these elements in the DOM tree and construct a new jQuery object from the matching elements.
The method optionally accepts a selector expression of the same type that we can pass to the $() function. If the selector is supplied, the elements will be filtered by testing whether they match it.
Consider a page with a simple list on it:
<ul> <li>list item 1</li> <li>list item 2</li> <li class="third-item">list item 3</li> <li>list item 4</li> <li>list item 5</li> </ul>
If we begin at the third item, we can find the element which comes just after it:
$('li.third-item').next().css('background-color', 'red');
The result of this call is a red background behind item 4. Since we do not supply a selector expression, this following element is unequivocally included as part of the object. If we had supplied one, the element would be tested for a match before it was included.
