java - How to set s:hidden value from another JSP element -


i have following form :

<s:form id="storno_form"     namespace="namespace"     action="action">      <sj:submit id="submitid"         key="btn.show" targets="cancelation_content"         cssclass="button" validate="true">     </sj:submit> </s:form>

and outside form :

<sj:select     href="%{geturl}"     id="selectcampaign"     autocomplete="true"     selectboxicon="true"     key="select.campaign"     name="campaignid"     list="campaigns"     listkey="id"     listvalue="name"     headerkey="-1"     headervalue="%{gettext('select.headervalue')}"     onselecttopics="realod"     oncompletetopics="customizeautocompleter" />

how can submit value of select element form: have tried :

<s:form id="storno_form"     namespace="namespace"     action="action">     <s:hidden  value="%{'campaignid'}" name="campaignid" />     <sj:submit id="submitid"         key="btn.show" targets="cancelation_content"         cssclass="button" validate="true">     </sj:submit> </s:form>

but not working ?

you can javascript

onchange="var el=document.getelementbyid('selectcampaign');document.getelementbyid('storno_form')['campaignid'].value=el.options[el.selectedindex].value;"

the same can onclick event of <sj:submit tag.

with jquery it's easier

$(document).ready(function() {   $('#selectcampagn').change(function() {    var val = $('#selectcampagn').val();     $('input[name=campaignid]').val(val);   }); });

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).
