DataTables Processing Info does not show up
<p>I included my server-side processing DataTables in jQuery UI TABS but after integration the processing info does not show up anymore :(<br><br>
This <a href="https://stackoverflow.com/questions/11311505/display-processing-message-in-jquery-datatables">stackoverflow.com</a> post writes something about a hidden "Processing..."-Div.<br>
Is it possible that my case matches a "z-index" problem?<br>
<br>
This is the DataTables code :</p>

<pre><code>$(document).ready(function() {

    $('#example').DataTable( {
        "processing": true,
        "serverSide": true,
        "ajax": {
            "url": "ajax_ssp_class.php",
            "type": "GET"
        },
        "order": [ [0,'asc'] ],
        "paging":true,
        "pagingType": "simple_numbers",
        "pageLength": 50,
        "lengthMenu": [[50, 100, 250, -1], [50, 100, 250, "All"]],
        "lengthChange": true
    } );
});
</code></pre>

<p>The proof whether the div is existent is tested as true:<br></p>

<pre><code>&lt;div id="example_processing" class="dataTables_processing" style="display: block; z-index: 10000;"&gt;Processing...&lt;/div&gt;
</code></pre>

<p><br><strong>THE SOLUTION</strong><br>
I added the following line to the pre-drawing. Now it works.</p>

<pre><code>"fnPreDrawCallback":function(){
    //alert("Pre Draw");
    $('#example_processing').attr('style', 'font-size: 20px; font-weight: bold; padding-bottom: 60px; display: block; z-index: 10000 !important');
}
</code></pre>
