Update the styling for the second list item within a specified unordered list class instantaneously

Looking to emphasize the second list item (li) within a selected dropdown list with a designated unordered list class of "chosen-results".

<div class="chosen-container chosen-container-single select-or-other-select form-select required chosen-processed" title="" id="edit_title_field_und_select_chosen">
  <div class="chosen-drop">
    <ul class="chosen-results">
      <li class="active-result result-selected" data-option-array-index="0">- Select -</li>
      <li class="active-result" data-option-array-index="1">select to create new title</li>
      <li class="active-result" data-option-array-index="2">This</li>
      <li class="active-result" data-option-array-index="3">That</li>
    </ul>
  </div>
</div>

In need of assistance utilizing jQuery to consistently target and highlight the second li element within the ul class "chosen-results" by altering its CSS attributes?

I've attempted various approaches, including a basic script such as

$("ul.chosen-results:second li").css('background-color','yellow');

The objective is to differentiate this specific list item from the others in terms of highlighting when hovered over.

UPDATE: Also explored the following methods, which unfortunately did not yield any visible changes:

(function ($) {
   $("ul.chosen-results li:nth-child(2)").css('background-color','yellow');
 //$('ul.chosen-results > li:eq(1)').css('background','red');
})(jQuery);

Answer №1

To choose the second child element, you can utilize the :nth-child(2) selector. Alternatively, you can opt for li:nth-of-type(2) to specifically target the second <li> child element.

Answer №2

For this task, you can utilize either :eq() or .eq(). Remember, these selectors are zero-based, so the element at index 1 is actually the second element in the list:

$('ul.chosen-results > li:eq(1)').css('background','yellow')
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div class="chosen-container chosen-container-single select-or-other-select form-select required chosen-processed" title="" id="edit_title_field_und_select_chosen">
  <div class="chosen-drop">
    <ul class="chosen-results">
      <li class="active-result result-selected" data-option-array-index="0">- Select -</li>
      <li class="active-result" data-option-array-index="1">select to create new title</li>
      <li class="active-result" data-option-array-index="2">This</li>
      <li class="active-result" data-option-array-index="3">That</li>
    </ul>
  </div>
</div>

Answer №3

Give this a shot

$("ul.chosen-results li:nth-child(2)").css('background-color','yellow');

Update :

I tested it out and it's working perfectly. Take a look at the code snippet below:

$("ul.chosen-results li:nth-child(2)").css('background-color','yellow');
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div class="chosen-container chosen-container-single select-or-other-select form-select required chosen-processed" title="" id="edit_title_field_und_select_chosen">
  <div class="chosen-drop">
    <ul class="chosen-results">
      <li class="active-result result-selected" data-option-array-index="0">- Select -</li>
      <li class="active-result" data-option-array-index="1">select to create new title</li>
      <li class="active-result" data-option-array-index="2">This</li>
      <li class="active-result" data-option-array-index="3">That</li>
    </ul>
  </div>
</div>
