How to return the specific page in jQuery Datatables paging?

Question

I have a datable and "Edit" button in each row. When I click that button, /edit/ url opens. Everything is Ok until now. But if I need to go back to the datatable, it starts from the first page. What can I do for that?

 $('#table').dataTable({
        "sDom" : 'rtFip>',
        'fnDrawCallback' : function() {
            $('input:checkbox, input:radio').checkbox();
        },
        'sPaginationType' : 'full_numbers',
        "bServerSide" : true,
        "sAjaxSource" : "{% url 'get_menu_list' %}"
  });

DataTables has option to store state in a cookie.

$(document).ready(function() {
    $('#example').dataTable( {
        "stateSave": true
    } );
} );

Storing the state in a cookie fails for large tables. This local storage solution works for large tables.

$(document).ready(function() {
    $('#example').dataTable( {
        "bStateSave": true,
        "fnStateSave": function (oSettings, oData) {
            localStorage.setItem( 'DataTables', JSON.stringify(oData) );
        },
        "fnStateLoad": function (oSettings) {
            return JSON.parse( localStorage.getItem('DataTables') );
        }
    } );
} );

How to return the specific page in jQuery Datatables paging?

Use fnPagingInfo

Get information about the paging settings that DataTables is currently using to display each page, including the number of records shown, start and end points in the data set etc.

      $.fn.dataTableExt.oApi.fnPagingInfo = function ( oSettings )
      {
        return {
          "iStart":         oSettings._iDisplayStart,
          "iEnd":           oSettings.fnDisplayEnd(),
          "iLength":        oSettings._iDisplayLength,
          "iTotal":         oSettings.fnRecordsTotal(),
          "iFilteredTotal": oSettings.fnRecordsDisplay(),
          "iPage":          Math.ceil( oSettings._iDisplayStart / oSettings._iDisplayLength ),
          "iTotalPages":    Math.ceil( oSettings.fnRecordsDisplay() / oSettings._iDisplayLength )
        };
      };


      $(document).ready(function() {
      $('#example').dataTable( {
      "fnDrawCallback": function () {
      alert( 'Now on page'+ this.fnPagingInfo().iPage );
      }
      } );
      } );
