Pipelined Ajax and Changing URL

melissa

Hi I am using the pipelined ajax to return multiple pages, and would like change the url and also have it return multiple pages.

I am using the code here: https://datatables.net/examples/server_side/pipeline.html. So the processing is server side and 5 pages are returned for each Ajax request.

//copied from pipeline documentation
$.fn.dataTable.pipeline = function ( opts ) { ... }

$(document).ready(function() {
    var example = $('#example').DataTable( {
        "processing": true,
        "serverSide": true,
        "ajax": $.fn.dataTable.pipeline( {
            url: 'scripts/server_processing.php',
            pages: 5 // number of pages to cache
        } )
    } );
} );

Initial load returns 5 pages. I would like to have a button that when clicked, changes the ajax url.

$('#myButton').on('click', function() {
   if(example.ajax.url() != 'scripts/secondary_server_processing.php') {
      tblSublist.clearPipeline();
      tblSublist.ajax.url('scripts/secondary_server_processing.php').load();
}

This works but only returns 1 page, not 5 pages. When debugging, the $.fn.dataTable.pipeline code is not being executed.

Resolved: The url value needs to be the entire pipeline function, not just the 'url' that you want

$('#myButton').on('click', function() {
   if(example.ajax.url() != 'scripts/secondary_server_processing.php') {
      tblSublist.clearPipeline();
      tblSublist.ajax.url(
         $.fn.dataTable.pipeline ({
            url: 'scripts/secondary_server_processing.php',
            pages: 5
         })
      ).load();
}
