javascript - Retrieving data from database on click -


i have raphael circle in page , want retrieve data database when circle clicked.

my piece of code purpose is:

var circle = r.circle(x, y, 10).click(retrievedata());

the problem is, function retrievedata called when creating circle , not when circle clicked. how can write piece of code, runs retrievedata if circle clicked , not on creation of object?

functions in events of raphael (like event driven paradigms) needs passed delegate (function pointer / function variable name.)

use following code (note absence of brackets after retrievedata function.)

var circle = r.circle(x, y, 10).click(retrievedata);

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).
