jquery - Issue with fading in a scroll to top -


i have site fixed side bar containing site header , site content scrolls on right. want fade in scroll top button within header (sidebar) using similar method http://gazpo.com/2012/02/scrolltop/ doesnt seem triggering, site having fixed sidebar?

how re-write jquery out scrolling content , not entire page scrolling

<script type="text/javascript"> $(document).ready(function(){       $(window).scroll(function(){         if ($(this).scrolltop() > 100) {             $('.scrollup').fadein();         } else {             $('.scrollup').fadeout();         }     });       $('.scrollup').click(function(){         $("html, body").animate({ scrolltop: 0 }, 600);         return false;     });  });

thanks

it 1 of many things (i'm streakycobra - jsfiddle useful here)

  • did check "scrollup" class of button, , not "scrollup"?

  • what css properties .scrollup? display set none, or opacity 0? if so, fade in , fade out can not affect it, fading in or out not visible.

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).
