javascript - Post variables not set when submitting a form with JS -


i have form submit javascript user clicks label. there weird behavior datas not posted. if submit form delay (even delay of 0) works.

here html:

<form action="/other-page" method="post">     <input id="val-1" type="checkbox" name="filter[]" value="1">     <label for="val-1">value 1</label>      <input id="val-2" type="checkbox" name="filter[]" value="2">     <label for="val-2">value 2</label> </form>

the script:

<script>     $('label').click(function() {         var form = $(this).closest('form')          // if use following line values won't set         form.submit()          // if use `settimeout` works, delay of 0         settimeout(function() {              form.submit()         }, 0)     }) </script>

it's not big issue can make work settimeout writing delay of 0 ugly. thought browser bug tested chrome , firefox , have same result.

any idea happening?

this because you're listening on label click. try listening checkbox click.

$('input[type=checkbox]').click(function() {     $(this).closest('form').submit(); });

clicking on label means browser "click" associated element. , since you're submitting form on label click, won't give browser chance this.

why settimeout 0 work, because trick post execution untill browser done current actions. can find more info on @ why settimeout(fn, 0) useful?

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).
