Question

我是新手，所以如果我的问题毫无用处，我很抱歉...... :)我希望能够点击搜索输出的结果（与下拉菜单相同，除了它以及...搜索栏）我在互联网上看了但没有什么可以让我感兴趣。谢谢。 PS：我的数据库的连接在另一个代码中但不应该有用到目前为止，这是我的代码：

<body>
    <h1>LIVE SEARCH WITH AJAX TEST</h1>
     <div class="search">
    <input type="search" name="search" id="recherche" class="search" onkeypress="showdiv()">
    </div>
    <div class="resultat" id="resultat" id="resultat" style="display: none;">
        <a>Please continue typing...</a>
        <br>
        <a href="#">&nbsp;</a>
        <br>
        <a href="#">&nbsp;</a>
        <br>
        <a href="#">&nbsp;</a>
        <br>
        <a href="#">&nbsp;</a>
    </div>
    <script type="text/javascript">
      function showdiv() {
          document.getElementById("resultat").style.display = "block";
      }
   </script>

PHP：

<?php

include 'connect.php';

if ($connect->connect_error) {
    die("Connection failed: " . $connect->connect_error);
}

if (isset($_GET['motclef'])) {
    $motclef = $_GET['motclef'];

    $sql = "SELECT name FROM smartphone WHERE name LIKE '%" . $motclef . "%' LIMIT 5";
    $result = $connect->query($sql);

    if ($result->num_rows > 0) {
        // output data of each row
        while($row = $result->fetch_assoc()) {
            echo  $row["name"] . "<br>";
        }
    } else {
        echo "Aucun resultat trouvé pour: " . $motclef;
    }
}
?>

jQuery：

$(document).ready(function(){
  var delay = (function(){
    var timer = 0;
    return function(callback, ms){
      clearTimeout (timer);
      timer = setTimeout(callback, ms);
    };
  })();

  $('#recherche').keyup(function() {
      delay(function(){
        var recherche = $('#recherche').val();
        if (recherche.length > 1) {
          $("#resultat").html("");
          $.get( "fetch.php", { motclef: recherche} )
          .done(function( data ) {
            $("#resultat").html(data);
          });
        }
      }, 1000 );
  });

});
