jquery - Store original text once -


i have simple function gets original text of div, , changes text when user resizes window (responsive site). when user enlarges window again, original text must shown. it's simple, have small problem.

function limith2text() {         var origtext = $(".result .right .mask").text();         var width = $(window).width();         if (width < 811) {             $(".result .right .mask").each(function () {                 var $this = $(this);                 $this.text($this.text().slice(0, 75));                 $this.append('...').show();             });         } else {             $(".result .right .mask").each(function () {                 $(this).text(origtext);             });         }     }

the console shows var origtext contains text of 3 [.result .right .mask] divs. see, html repetition of [.result .right .mask]. instead of (for example) 'hello text', shows 'hello text hello text hello text'. when user resizes, grows exponential browser crashes. can't figure out how once store text of 1 div?

thanks help!

try using .eq():

var origtext = $(".result .right .mask").eq(0).text();

this reduce set of matched elements 1 @ specified index , store text of 1 div.

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 ...
