What is the best way to sort out the <li> elements within a <ul> that has a specific id

        <ul class="apple" id="A">
             <li>
             <li>
              .....
              ......
              ......

        </ul>

         <ul class="apple" id="C">
             <li>
             <li>
              .....
              ......
              ......

        </ul>

The code snippet above showcases a list item with the id of C that is contained within an unordered list with the class of "apple".

When trying to select the ul element with the id B using jQuery, the following syntax was attempted: $(selector).find('ul.apple #B'). However, this method did not yield the desired result.

The objective is to display all list items under the ul element with the class of "apple" and id of "C". This functionality is being implemented in FTL (Freemarker) and there is an attempt to call the id defined in Freemarker from JavaScript.

Thank you for your assistance :)

Answer №1

It is crucial for ids to be unique within a document. The only selector you need to target an id is $('#B'), eliminating the need for any additional selectors like .find since there will always be only one matching element on the page.

If you are looking to reference the li elements under the #B id, here are two approaches:

// obtain a reference to the list
var $B = $('#B');
// get children (which are lis)
var $lis = $B.children();

Alternatively, you can directly retrieve the lis as follows:

var $lis = $('#B li');

Answer №2

Typically, all you really need to include is the ID since it's unique on the page. A selector like this should suffice:

#B li

However, if you find yourself needing to specify both the element and class - perhaps for consistency across multiple pages - you can do so without any spaces between them:

ul.apple#b li

Answer №3

The HTML 4.01 guidelines clearly state that each element's ID should be distinct.

Therefore, to easily target an element by its unique ID, you can simply use the following jQuery syntax:

$('#A');

Answer №4

locate user interface elements using their id and class name: $('B .apple')
