.next( [selector ] ) Returns: jQuery

Description: Get the immediately following sibling of each element in the set of matched elements. If a selector is provided, it retrieves the next sibling only if it matches that selector.

  • version added: 1.0.next( [selector ] )

    • selector
      Type: Selector
      A 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 immediately following sibling 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 immediately following sibling matches the selector, it remains in the newly constructed jQuery object; otherwise, it is excluded.

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:

1
 
                                

                                  

                                    $('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.

Examples:

Example: Find the very next sibling of each disabled button and change its text "this button is disabled".
