I have an HTML table which I want to update every 1 second on page. It have few div and classes within. So I tried AJAX to update it every 1 second. HTML is this:-
<div class="abcd">
<div style='float: left;'>
<br><br>
<p style="padding-left:16px; font-size: 20px;">Amount(<?php echo $market; ?>) | Price(<?php echo $bm; ?>)   | Total(<?php echo $bm; ?>)</p>
<div class="panel-hello scrollbar" id="style-11">
<div class="data-table">
<table class="table table-hello table-bordered table-hover force-overflow" id="btcaddresses">
<tbody style="border: 1px solid green; height: 300px; overflow-y: scroll;">
</tbody>
</table>
</div>
</div>
</div>
And AJAX script:-
function loadXMLDoc()
{
var xmlhttp;
if (window.XMLHttpRequest)
{// code for IE7+, Firefox, Chrome, Opera, Safari
xmlhttp=new XMLHttpRequest();
}
else
{// code for IE6, IE5
xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
}
xmlhttp.onreadystatechange=function()
{
if (xmlhttp.readyState==4 && xmlhttp.status==200)
{
document.getElementsById("btcaddresses").innerHTML=xmlhttp.responseText; // your div
}
}
xmlhttp.open("GET","getdatabase.php",true); //your php file
xmlhttp.send();
}
window.setInterval(function(){
loadXMLDoc();
}, 1000);
And getdabase.php contains:-
<?php
require('../setup.php');
$seql = "select price, sum(total), sum(aleft) from trade where status = 'active' and bm = 'USD' and m = 'BTC' and type = 'sell' group by price";
$query100 = mysqli_query($conn, $seql);
while ($row = mysqli_fetch_array($query100))
{
echo '<tr style="cursor: pointer; font-size: 15px;">
<td>'.number_format($row['sum(aleft)'], 8).'</td>
<td>'.number_format($row['price'], 8).'</td>
<td>'.number_format($row['sum(total)'], 8).'</td>
</tr>';
}
mysqli_close($conn);
?>
Problem is , it is not working and even if does it's not having any table classes specified in class.
<?php
require('../setup.php');
$seql = "select price, sum(total), sum(aleft) from trade where status = 'active' and bm = 'USD' and m = 'BTC' and type = 'sell' group by price";
$query100 = mysqli_query($conn, $seql);
$result = '';
while ($row = mysqli_fetch_array($query100))
{
$result .= '<tr style="cursor: pointer; font-size: 15px;">
<td>'.number_format($row['sum(aleft)'], 8).'</td>
<td>'.number_format($row['price'], 8).'</td>
<td>'.number_format($row['sum(total)'], 8).'</td>
</tr>';
}
mysqli_close($conn);
echo $result;
?>
This should work, but indeed you should return a json.
Edit : full html code working fine for me : (I had to remove some php parts)
