javascript - jQuery seed each() with an array of elements -


the script below throwing error (customfields not defined). need pass element ids differently?

i'm trying seed array form fields i'm looking calculate. should iterate through each of form fields in array , increment sum variable value of form element.

jquery(document).ready(function(){      jquery("#customfield_21070").attr('style','width:60px');     jquery("#customfield_21070").attr('disabled','disabled');      var customfields = [     '#customfield_11070',     '#customfield_11071',     '#customfield_20071',     '#customfield_20072',        '#customfield_20073',     '#customfield_20074'     ];      jquery(customfields).each(function() {         jquery(this).attr('style','width:60px');              jquery(this).keyup(function(){                 calculatesum();             });           });      });      function calculatesum() {          var sum = 0;          //iterate through each textboxes , add values         jquery(customfields).each(function() {              //add if value number             if(!isnan(this.value) && this.value.length!=0 && this.id !== "customfield_21070") {                 sum += parsefloat(this.value);             }          });         //.tofixed() method roundoff final sum 2 decimal places         jquery("#customfield_21070").val(sum.tofixed(2));     }

jquery's .each() method meant iterate on jquery object. should use simple for loop iterate array – it's lot faster using jquery .each() method, anyway.

for(var i=0, len=customfields.length; i<len; i++) {     console.log(customfields[i]); }

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 ...
