Javascript 带有jquery的PHP函数按类动态随机插入记录

我创建了下面的函数来显示具有随机名称的块。创建另一个数组，然后抓取更多记录，并使用fadeIn、fadeOut效果按类名将它们随机插入标记中。除了剧本之外，所有的作品实际上都是在李的作品中注入了“新名字”

    function query_in_memoriam() {

/*authentication call hidden */
$query = "SELECT formatted_name FROM xxxx WHERE xxxx = 'xxxx' ORDER BY RAND(last_name) LIMIT 30";
$result = mysqli_query($link, $query);

$i = 0;
$buildMemoriam = "";
while ($i < 20){
    $result_array = mysqli_fetch_array($result);
    $buildMemoriam .= '<li class="name">'.$result_array['formatted_name'].'</li>';
    $i++;
}   

$buildMemoriamDisplay = '<div id="memoriam" class="row bg-standard">
    <h2>In Memoriam </h2>
    <p>In progress, randomizes on refresh, just need to fade in/out names. JA 8/31</p>
    <div id="memoriam-container">
        <ul class="memoriam-items">
        ' . $buildMemoriam . '
        </ul>
    </div>
</div>';

$i = 21;
$array = "";
    while ($i < 30 ){
        $result_array = mysqli_fetch_array($result);
        $array = '"'.$result_array['formatted_name'].'",';
        $i++;
    }
?>
<script>
jQuery(document).ready(function( $ ) {
var names = [<?php json_encode($array); ?> ];
var lis = document.getElementsByClassName('name');

window.setInterval(function changeNameRandomly() {
  var randomNamesIndex = Math.floor(Math.random() * names.length);
  var randomLiIndex = Math.floor(Math.random() * lis.length);
  var randomName = "";
  $(lis[randomLiIndex]).fadeOut("slow", function() {
    randomName = names[randomNamesIndex];
    var addit = true;
    $(".name").each(function()
    {
        if ( $(this).text() == randomName ) {
            // console.log("Duplicate: looking again");
            addit = false;
            $(lis[randomLiIndex]).fadeIn();
        }
     });
     if(addit) {
        $(lis[randomLiIndex]).html(randomName);
        // console.log(randomName);
        $(lis[randomLiIndex]).fadeIn();
     }
  }.bind(this));

}, 2000);
});
</script>
<?php
return $buildMemoriamDisplay;
}

你不是在制作数组，而是在制作字符串。。。每次都要更换。这里是更新的代码

$array = array();
while ($i < 30 ){
     $result_array = mysqli_fetch_array($result);
     $array[] = $result_array['formatted_name'];
     $i++;
}

还有这个

var names = <?php echo json_encode($array); ?>;
