triggers - jquery: What happens after binding an event more than once? -


thanks jquery, .on method binds trigger element. have html like:

<div class='xyz'>click me</div>

and script like:

$('.xyz').on('click', function(){   alert('why?'); }); $('.xyz').on('click', function(){   alert('why?'); });

clicking on click me div triggers alert 2 times. it's ok, but:

  1. what happens after binding second click trigger div?
  2. is browser behavior or done jquery variables?

here fiddle: http://jsfiddle.net/hpmhpm/fcrec/

what happens after binding second click trigger div?

jquery register's new click event handler on .xyz, no matter, how many event handler's attached element

is browser behavior or done jquery variables?

it's done jquery

you can have many event handler's want on same element, consider scenario -

this valid :

$('.xyz').on('click', function(){   // work }); $('.xyz').on('click', function(){   // other work });

linux - Does gcc have any options to add version info in ELF binary file? -

i mean whether gcc can insert source code version infor elf binary section or similar. not want change source file, add info gcc option in makefile. you can emit version info text file, turn text file object file statically link executable. the first step simple have write code: script or write version info in format plain text file. write makefile rule produce version.o version.txt, using objcopy . you'll have object file 2 useful symbols defined in it: beginning , end of textual version info. add generated object executable, , you'll able access version 2 ways: running strings on binary, or writing code in application print version string (you'll need declare start , end symbols variables in header file).
