javascript - Expiring a page when back button is clicked -


i have page searches flight. if user has clicked button in browser, should display error message. tried following code: -

   function preventback(){window.history.forward();}      settimeout("preventback()", 0);      window.onunload=function(){null};

problem is not redirecting page saying "this document has been expired."

you can not detect if user has clicked "back" button natively. reason

this document has been expired

is send new form again , againt on previous page. great flaw in architecture.

however if still insist on approach, you can use this plugin. redirect error page, when back-click detects. (like window.location = '/path/to/error/page.html')

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 ...
