Updating sort order during sort change event - jQuery UI -


i want value of list element index of sorted position during sort event.

this value should update automatically during sort change event. 

        <script type="text/javascript">         $(function() {             $('#sortable').sortable({                 start : function(event, ui) {                     var start_pos = ui.item.index();                     ui.item.data('start_pos', start_pos);                 },                 change : function(event, ui) {                     var start_pos = ui.item.data('start_pos');                     var index = ui.placeholder.index();                      if (start_pos < index) {                         $('#sortable li:nth-child(' + index + ')').html(index-2);                     } else {                         $('#sortable li:eq(' + (index + 1) + ')').html(index + 1);                     }                 },                 update : function(event, ui) {                     var index = ui.item.index();                     $('#sortable li:nth-child(' + (index + 1) + ')').html(index);                  },                 axis : 'y'             });         });       </script>

i created fiddle http://jsfiddle.net/jagan2explore/4mcpq/

to explain requirement.

if move 1'st element 5th position other elements values updated rightly, if move 5th 1'st value updates accordingly.

suppose if move list element 1 5 & 5 2 without leaving (during single sort event ), values not updated accordingly.

am missing something??

any appreciated. in advance

try this:

update : function(event, ui) {     var index = ui.item.index();     var start_pos = ui.item.data('start_pos');      //update html of moved item current index     $('#sortable li:nth-child(' + (index + 1) + ')').html(index);      if (start_pos < index) {         //update items before re-ordered item         for(var i=index; > 0; i--){             $('#sortable li:nth-child(' + + ')').html(i - 1);         }     }else {         //update items after re-ordered item         for(var i=index+2;i <= $("#sortable li").length; i++){             $('#sortable li:nth-child(' + + ')').html(i-1);         }     } },

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 ...
