当我添加另一个功能（如通知）时，我的搜索功能将不起作用

这是我的搜索代码，当没有添加通知功能时它可以正常工作。但是一旦我添加了“通知”功能，它就不会使这个“搜索”功能起作用。请帮忙

编辑：我添加了有关如何显示具有搜索功能的表格数据的代码。

    $(document).ready(function(){
            $("#search").keyup(function(){

                if( $(this).val() != "")
                {
                    $("#table tbody>tr").hide();
                    $("#table td:contains-ci('" + $(this).val() + "')").parent("tr").show();
                }
                else
                {

                    $("#table tbody>tr").show();
                }
            });
        });

        $.extend($.expr[":"], 
        {
            "contains-ci": function(elem, i, match, array) 
            {
                return (elem.textContent || elem.innerText || $(elem).text() || "").toLowerCase().indexOf((match[3] || "").toLowerCase()) >= 0;
            }
        });

那么这是其输入的 Html 代码

    <input type="search" id="search" class = "search" name = "search" placeholder="Search...">

那么这是我如何在我的页面中填充表格的代码

    <label id = "title">Manage Licenses</label><br/> 
            </div>
        </div>
        <div class="row" style = "padding-bottom : 20px;">
            <?php
            $qry = $con->prepare("SELECT * FROM tbllicense, tblrequests WHERE ExpirationDate < DATE_ADD(NOW(), INTERVAL 2 MONTH) AND 
            tblrequests.ID = Request_ID AND tblrequests.Status = 'accepted' ORDER BY ExpirationDate");
            $qry->execute();
            $rows = $qry->fetchAll(PDO::FETCH_ASSOC);
            $expiredcount = 0;
            ?>
            <table class = "table" id = "table">
            <thead>
                <th>Record ID</th>
                <th>Name</th>
                <th>Email</th>
                <th>License Type</th>
                <th>Expiration</th>
                <th>Options</th>
                <tbody>
                <?php
                foreach ($rows as $row) {
                    ?>
                    <tr>
                        <td><?= $row["Request_ID"] ?></td>
                        <td><?= $row["txtFName"] . " " . $row["txtSurname"] ?></td>
                        <td><?= $row["txtEmail"] ?></td>
                        <td><?= $row["txtLicense"] ?></td>
                        <td><?= date("M d, Y", strtotime($row["ExpirationDate"])) ?></td>
                        <td><input type = "button" class = "btnAccept" value = "Renew" onclick = "renew(<?= $row["Request_ID"] ?>)"/></td>
                    </tr>
                    <?php
                }
                ?>
                </thead>
                </tbody>
            </table>
        </div>

当我添加此功能时（通知）。搜索无法正常工作，当我在搜索表单中输入时，结果将是空白的。

    <li style = "float:right">
        <div style = "float:right">
        <?php
        $qry = $con->prepare("SELECT * FROM tbllicense, tblrequests WHERE ExpirationDate < DATE_ADD(NOW(), INTERVAL 2 MONTH) AND 
            tblrequests.ID = Request_ID AND tblrequests.Status = 'accepted'
            UNION
            SELECT * FROM tblvisa, tblrequests WHERE ExpirationDate < DATE_ADD(NOW(), INTERVAL 2 MONTH) AND 
            tblrequests.ID = Request_ID AND tblrequests.Status = 'accepted' ORDER BY ExpirationDate"
            );
            $qry->execute();
            $rows = $qry->fetchAll(PDO::FETCH_ASSOC);

        if ($qry->rowCount()) {

            echo '<img width=15 height=13 src="img/alert.png" />';
