html - IE10 - avoid form names in global scope for javascript -


i've got web application search box, , onkeypress event calls query.keypress(). query defined in included javascript file. of time works correctly.

on ie10 screens, trying use search box gives error:

error: object doesn't support property or method 'keypress'

what have found of screens have query form name , id of 'query'. seems in ie10 appears in global scope, , overrides object literal javascript. info, search box not inside form.

i've replaced onkeypress code alert(query); , see [object htmlformelement] confirms happening.

does know how stop happening on ie10?

this problem can negated using own namespace, rather polluting global scope time , time again.

var my_stuff = {};  my_stuff.query = function () {}; my_stuff.my_const = 4; my_stuff.utilityfunction = function () {};

... way, breaks if add form element named my_stuff, won't break if add form elements called query, my_const or utilityfunction (not best names, gist).

like said, doesn't fix problem, negates it. polluting global scope bad practise.

you can, of course, not use global variable @ all, through closures. require lot of restructuring, if have application spread on multiple files, , no build process in place combine files.

(function () {     var query = function () {};      // query.keypress() as want! }());  // note can't use outside of closure.

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
