javascript - How to implement a generic click event for anchors -


currently have php script throws out bunch of buttons(format in case needed is

<a class="classinfo" id="id">name</a>

the file retrieved dynamically , there can many buttons possible, maybe none , maybe million(unlikely though). anyways javascript. need use javascript , cant redirect user website(mostly because operation repeated heavily , gets extremely tedious..).

is possible me use combination of javascript + jquery detect button pressed , operation appropriately?

example of hoping this: user clicks 1 of buttons(which has unique id number). javascript detects button clicked(i cant use fixed code number of buttons , ids can change whenever feel it). javascript send out ajax request , fancy operations(i got part covered).

now possible me detect button clicked? struggling this.

the target property of event object tell element clicked on.

document.addeventlistener('click', function (e) {   var target = e.target;   if (target.tagname && target.tagname.tolowercase() == "a") {     alert(target.id);   } });

see a live demo

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).
