jquery - How to put the onchange event of a select list? -


i ready next problem. have select list populated follows:

<select id= "tables" name= "tables">     <option value="select">-- select --</option>     <option value = student> student</option>     <option value = teachers > teachers </option>     //etc.. </select>

on onchange event of select list select list populated.

my first problem when select item, "student", view still remains on "select" option.i want should show item select.

my second query is, if not write "-- select --" , "student first item" when click student first time nothing happens means 2nd selct list doesnot populated.

please help!

assuming html :

<select id= "tables" name= "tables">     <option value="">-- select --</option><!-- setting value none -->     <option value = student> student</option>      <option value = teachers > teachers </option> </select>

with jquery, it'll change event :

$('#tables').on('change', function(e) {     var value = $(this).val();      if(value.length != 0) {         alert(value);     }  });

see live example there.

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).
