twitter bootstrap - jQuery validation regex for white space getting a "Uncaught TypeError: Cannot call method 'call' of undefined error" -


here jquery code per previous stackoverflow question

$('#productid').validate({      rules: {          product: {              required: true,              term: {regex: /^$|\s/}          }      },      messages: {          product: {              required: "a text much",              term: "please avoid spaces"          },      },         showerrors: function (errormap, errorlist) {           $.each(this.successlist, function (index, value) {              $('#'+value.id+'').popover('destroy');          });            $.each(errorlist, function (index, value) {               $('#'+value.element.id+'').attr('data-content',value.message, 'title', 'oops!').popover({                  placement: 'top',                  trigger: 'manual',                  delay: { show: 500, hide: 5000 }              }).popover('show');           });       }   });

what trying show popover if there white space in term entered. every time gives me error

uncaught typeerror: cannot call method 'call' of undefined

i know wrong regex part. because tried same code minlength , worked well. doing wrong?

p.s using twitter bootstrap popover.

update: more error

uncaught typeerror: cannot call method 'call' of undefined ----------jquery.validate.js:504      $.extend.check ---------- jquery.validate.js:504      $.extend.element ---------- jquery.validate.js:357     $.extend.defaults.onfocusout ---------- jquery.validate.js:231      delegate ---------- jquery.validate.js:317      (anonymous function) ---------- jquery.validate.js:1184      jquery.event.dispatch ---------- jquery.js:3075      elemdata.handle ---------- jquery.js:2751      jquery.event.trigger ---------- jquery.js:2987     jquery.event.simulate ---------- jquery.js:3302      handler

my guess should using this.errorlist instead of errorlist in second $.each. it's possible difference between 2 loops in value.id , value.element.id significant too.

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 ...
