Div标签未重新加载

I am attempting to reload only a div tag on a page when there is new content in the database

in Ajax I test for new content:

function adshandler() {
var d = new Date();
var cache = d.getTime();
$.getJSON("check_time.php?cache=" + cache, function(update) {
    if (update.count === true) {
        //location.reload();
        $('#slideshow').reload();
    }
}); 
} 
setInterval(adshandler, 10000);

The div is on the same page as the ajax:

//Monday Afternoon
if ($dayofweek == "Monday" && $timeofday >= "12:00:00" && $timeofday <= "16:59:59"){
//Monday afternoon timeslot
echo "<div id='slideshow'>";
$stma= $conn->prepare("SELECT `Monday_Afternoon`
FROM `Client_Ads`");
$stma->execute();
while($resultst = $stma-> fetch()){
$mondayafternoonlist = $resultst["Monday_Afternoon"];
echo "<div class='slideshow'>";
echo "<img src='/$mondayafternoonlist'>";
echo "</div>";
}
echo "</div>";
}

There are more than one div with a similaridandclass, each one behind anifandelse if` statement, depending on the day of the week etc.

My $('#slideshow').reload(); is not working? I have also tried $('#slideshow').load();.

    You can achieve it using .load() function in very few line. Following is a working example.

    <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.2.2/jquery.min.js"></script>
    <script>
        function changeDate() {
            $("#d2p").load(location.href + " #d2");
        }
    </script>
    <div id="d1p">
        <div id="d1">
            <?php echo date("H : i : s"); ?>
        </div>
    </div>
    

    This is the DIV which is going to refreshed on click of button partially on this page.

    <div id="d2p">
        <div id="d2">
            <?php echo date("H : i : s"); ?>
        </div>
    </div>
    <button onclick="changeDate();">Change Date</button>
    

    Here is the demo Load div without refreshing entire page
