javascript - slickgrid - How to loop through rows which are outside canvas? -


i having markers on map , same number of rows in slickgrid?

what want when marker clicked id of marker matched rows , corresponding row should selected.

here code:

var $canvas = $(grid.getcanvasnode()); var $allrows = $canvas.find('.slick-row');      $($allrows).each(function() {         if ($(this).rowid == selectedmarker) {             $(this).addclass("active-row");              grid.scrollrowintoview($(this).index());         }     });

it works fine when row want present in grid grid dom contains 8 rows @ time (the grid has 30 rows).

how can loop through data?

you shouldn't modifying slickgrid's dom @ all. slickgrid overwrite changes it's rendering rows in view (with buffer). when scroll past buffer changes made dom lost.

you have change row's data , allow slickgrid add appropriate classes dom when it's rendering.

edit:

slickgrid setup:

dataview.getitemmetadata = metadata(dataview.getitemmetadata);  function metadata(metadataprovider) {   return function(row) {     var item = this.getitem(row),         ret = metadataprovider(row);      if (item && item.isactive) {       ret = ret || {};       ret.cssclasses = (ret.cssclasses || '') + ' active-row';     }      return ret;   }; }

then when click on marker:

var item = dataview.getitembyid(selectedmarker); var row  = dataview.getrowbyid(selectedmarker); item.isactive = true; dataview.updateitem(item.id, item); grid.scrollrowintoview(row);

Why does Ruby on Rails generate add a blank line to the end of a file? -

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 ...
