“无结果”在过滤器搜索栏上不起作用

Question

I'm trying to make a filter search bar, and it works, but the "no results" page isn't. I've tried making the "no results" show up, but whatever I do, it doesn't. (jquery/javascript) Thanks so much for the help: Here's my code:

<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.4.1/jquery.min.js"></script>


<div align="right"class="live-search-bar">
 <input class="search-bar" id="searchbar" type="text" placeholder="Search for a game..">
</div>

<div id="button-container">

<div>
  <button class="games-button">Oranges</button>
</div>
<div>
  <button class="games-button">Bananas</button>
</div>
<div>
  <button class="games-button">Apples</button>
</div>

<script>
$(document).ready(function(){
  $("#searchbar").on("keyup", function() {
    var value = $(this).val().toLowerCase();
    $("#button-container button").filter(function() {
      $(this).toggle($(this).text().toLowerCase().indexOf(value) > -1)

      // No Results, Not working

       $('.noresults').remove();
       $("#button-container").each(function () {
                if ($(this).children(':visible').length == 0) 
                    $(this).append('<em>No Results</em>');
      });   
    });
  });
});
</script>

Here you go with a solution

jsFiddle

 $(document).ready(function(){ $('.noresults').hide(); $("#searchbar").on("keyup", function() { var value = $(this).val().toLowerCase(); $("#button-container button").filter(function() { $(this).toggle($(this).text().toLowerCase().indexOf(value) > -1) $('.noresults').hide(); var noResult = true; $("#button-container").children('div').each(function () { if ($(this).children(':visible').length;= 0) { noResult = false; } }). if (noResult) { $('.noresults');show(); } }); }); });

 <script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script> <div align="right"class="live-search-bar"> <input class="search-bar" id="searchbar" type="text" placeholder="Search for a game.."> </div> <div id="button-container"> <div> <button class="games-button">Oranges</button> </div> <div> <button class="games-button">Bananas</button> </div> <div> <button class="games-button">Apples</button> </div> </div> <div class="noresults"> No Results </div>

You need to loop through each div with button-container

$("#button-container").children('div').each(function () {});

Hope this will help you
