Refresh a table with jQuery/Ajax every 5 seconds

So I have a table pulling information from a database and I was wondering how I could make it refresh its information without reloading the whole page.

You should have a page that return the information and pull data using Ajax / jQuery. 

<div class="result"></div>

setInterval(function() {

    $.get('table.php', function(data) {
      $('#result').html(data);
    });

}, 5000);

The following works with JQuery Datatables 1.10

`var tableName;
//Set AJAX Refresh interval.
$(function() {
    setReloadInterval(10);  //Refresh every 10 seconds. 
}

//Because function takes seconds we * 1000 to convert seconds to milliseconds.
function setReloadInterval(reloadTime) {
    if(reloadTime > 0)
        internalId = setInterval("reloadTable()", (reloadTime * 1000);
}

//Auto Refresh JQuery DataTable 
function reloadTable() {
    tableName.ajax.reload();
}

//Table defined...
$(document).ready(function () {
    tableName = $('#tableName').DataTable({
        "sAjaxSource": "/someUrl",
});`

You'll need a getTable.php page that displays your table, and nothing else: no headers, footers, etc.

PHP (getTable.php) - this can be any server side code (asp, html, etc..)

<?php
    echo '<table><tr><td>TEST</td></tr></table>';
?>

Then, in your JS, you can easily refresh the table by using the load() method:

HTML

<div id="tableHolder"></div>

JS

<script type="text/javascript">
    $(document).ready(function(){
      refreshTable();
    });

    function refreshTable(){
        $('#tableHolder').load('getTable.php', function(){
           setTimeout(refreshTable, 5000);
        });
    }
</script>

Use ajax, following example is in jQuery:

$(function() {
    var prevAjaxReturned = true;
    var xhr = null;

    setInterval(function() {
        if( prevAjaxReturned ) {
            prevAjaxReturned = false;
        } else if( xhr ) {
            xhr.abort( );
        }

        xhr = $.ajax({
            type: "GET",
            data: "v1="+v1+"&v2="+v2,
            url: "location/of/server/script.php",
            success: function(html) {
                 // html is a string of all output of the server script.
                $("#element").html(html);
                prevAjaxReturned = true;
           }

        });

    }, 5000);
});

The success function assumes that your server script outputs the html that you want to replace in the element with id 'element'.

Here is another option for you to use. This solution is using an IIFE which is preferred over setInterval. You can read more about IIFE at the link above.

JAVASCRIPT:

var $results = $('#results'),
    loadInterval = 5000;
(function loader() {
    $.get('script.php', function(html){
            $results.hide(200, function() {
                $results.empty();
                $results.html(html);
                $results.show(200, function() {
                    setTimeout(loader, loadInterval);
                });
            });
    });
})();

HTML:

<div id="results"></div>

setTimeout(function(){

      jqueryFunction(Args);

},100);

will work...

100 = 100 milliseconds
