javascript - datatables and server-side processing - load on demand -


i've build simple table using datatables , connected server-side script populate table data.

above table have 2 checkboxes , 2 date selects specify filter criterias. when page loading table filled, because @ startup datatable pulling first page of data server.

i disable first initial data load, when page loaded i'll empty table, after i'll select criterias , press 'load' button data loaded.

i know how add filter criterias server params, need load data server after user click button.

below datatable script:

var mytable= $('table#mytable').datatable({     "table-layout": "fixed",     "bjqueryui": true,     "sdom": '<"h"lpr>t<"f"ip>',     "idisplaylength": 25,     "alengthmenu": [[25, 50, 100, 500], [25, 50, 100, 500]],     "bsort": false,     "spaginationtype": "full_numbers",     "bpaginate": true,     "bprocessing": true,     "bserverside": true,     "sajaxsource": "data.asmx/sales",     "fnserverdata": function(ssource, aodata, fncallback) {         var secho = aodata[0].value;         var idisplaystart = aodata[3].value;         var idisplaylength = aodata[4].value;          $.ajax({             contenttype: "application/json; charset=utf-8",             type: "post",             url: ssource,             //below parameters             data: "{'secho': '" + secho                 + "','idisplaystart': '" + idisplaystart                 + "','idisplaylength': '" + idisplaylength                 + "'}",             success: function(msg) {                 fncallback(msg.d);             },             error: function(xmlhttprequest, textstatus, errorthrown) {                 alert(xmlhttprequest.status);                 alert(xmlhttprequest.responsetext);             }         });     },     "bautowidth": false,     "aocolumns": [{             "stype": "numeric",             "mdata": "nr",             "swidth": "50px"         }, {             "stype": "string",             "mdata": "name"         }, {             "stype": "string",             "mdata": "surname"         }] });

you specify ideferloading parameter datatables, number of records table contains in dom, or 0 if no records.

$(document).ready(function() { $('#example').datatable( {     "bprocessing": true,     "bserverside": true,     "sajaxsource": "scripts/server_processing.php",     "ideferloading": 0 } ); } );

running rails generate controller foo home results in: class foocontroller < application controller def home end end (there's nothing on line in actual file, blank line) is there purpose blank line? it's common use newline indicate end of line, last line. many editors (like vi, use) add in newline silently. consensus text files (especially in unix world) should end in newline, , there have been problems historically if wasn't present. why should text files end newline? the tool used count lines in file "wc" counts newlines in file, without trailing newline show 3 instead of 4. it improves readability of templates used in generator. consider: https://github.com/rails/rails/blob/master/railties/lib/rails/generators/rails/controller/templates/controller.rb to remove trailing newline, template have last line of: end<% end -%> instead of: end <% end -%> that seems less readable me. the discussion below refers ...
