Answer 1

at the end i resolved like this

searchBar.on("keyup", ()=>{
  if (searchBar.val() != "") {
    $(".users-list-name").each((i, obj)=>{
      console.log($(obj))
      if (!$(obj).text().toLowerCase().includes(searchBar.val().toLowerCase())){
        $(obj).parent().parent().parent().hide()
      } else {
        $(obj).parent().parent().parent().show()
      }
    }
  )
} else {
  $(".users-list").show()
}
})

Answer 2

this was refering to the window. I fixed it so it grabs the actual element: let elem = $(".users-list-name")[index]

 const searchBar = $(".users-layout.search input") searchBar.on("keyup", () => { if (searchBar.val().= "") { $(".users-list-name").each(index => { let elem = $(".users-list-name")[index] if (.$(elem).text().toLowerCase().includes(searchBar.val().toLowerCase())) { console.log($(elem).text()) $(elem).hide() } else { console.log($(elem).text()) $(elem).show() } }) } })

 <div class="users-layout"> <div class="search"> <input /> </div> </div> <div class="users-list"> <a href="#" class="back-icon"> <i class="fas fa-arrow-left"></i></a> <div class="content"> <div class="details"> <span class="users-list-name">Admin</span> <p>Test Message</p> </div> </div> <div class="status-dot"><i class="fas fa-circle"></i></div> </div> <div class="users-list"> <a href="#" class="back-icon"> <i class="fas fa-arrow-left"></i></a> <div class="content"> <div class="details"> <span class="users-list-name">Admin</span> <p>Test Message</p> </div> </div> <div class="status-dot"><i class="fas fa-circle"></i></div> </div> <script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
