Question

라이브 검색을위한 플러그인을 사용하고 있습니다. 모든 것이 잘 작동하고 있습니다. 단지 아약스 요청이 시작될 때 결과에 ​​나타나지 않는 로딩 png를 추가하려고합니다. form id = "search-kb-form"클래스를 추가하기 위해 코드를 사용자 정의하고 결과가 완료되면 클래스를 제거하십시오.

 <form id="search-kb-form" class="search-kb-form" method="get" action="<?php echo home_url('/'); ?>" autocomplete="off"> 
     <div class="wrapper-kb-fields"> 
      <input type="text" id="s" name="s" placeholder="Search what you’re looking for" title="* Please enter a search term!"> 
      <input type="submit" class="submit-button-kb" value=""> 
     </div> 
     <div id="search-error-container"></div> 
    </form>
