javascript - Alert user for unsaved changes in page within panels using jquery -


i have situation here, need stop user if user has left unsaved changes on page.

i got information on internet moving current page other page like

var warnmessage= "you have unsaved changes"; $('input:not(:button,:submit),textarea,select').change(function () {                 window.onbeforeunload = function () {                     if (warnmessage != null) return warnmessage;                 };             });              $('input:submit').click(function(e) {                 warnmessage = null;             });

this works fine when closing tab or url getting changed.

i have panels on page 3 different panels;each submit, cancel , reset. now, need alert user when happens open panel; last panel has unsaved changes user should alerted

if he/she has unsaved changes on panel, submit/reset/cancel button clicked should confirm user.

is possible?

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).
