Answer 1

I have given id for the check box then below code is working for me

 $(document).ready(function() {  
            $('#yourDataTableID').DataTable();  
            $("#button").click(function() {  
                var chcklist = new Array();  
                var oTable = $('#yourDataTableID').dataTable();  
                var rowcollection =  oTable.$("#checkboxID:checked", {"page": "all"});  
                rowcollection.each(function(index,elem) {  
                    chcklist.push($(elem).val());    
                });       

                 $.ajax({
                      type : 'POST',
                       url: "/DataTableQuery/checkPaginatedData",
                      dataType : 'JSON',
                      data : {list: chcklist},
                      success : function(data, success) {           

                }
              }); 
            });  
        });

Answer 2

See here: How can I select all checkboxes from all the pages in a jQuery DataTable

The answer should be the line:

var allPages = table.fnGetNodes();
