Symfony: Using JavaScript in a onChange-event in a form and calling an action from the JS-Function -


i never used javascript before need in symfony-project (symfony 1.4) , have problems add code working:

i have template (indexsuccess) in module „aktionlimit“ show values of variables of object of class „aktion“ :

<p>value1: <?php echo $aktion->getvalue1()  ?></p> <p>value2: <?php echo $aktion->getvalue2()  ?></p> <p>value3: <?php echo $aktion->getvalue3()  ?></p>  <?php include_partial('form', array('form' => $form)) ?>

this executeindex:

$this->aktion = aktionlimitpeer::getbyname($this->getuser()->getattribute('aktion'));  $aktionparam = new aktion(); $aktionparam->setname($this->aktion->getname());  $this->form = new aktionlimitform(array(), array("aktion" => $aktionparam));

the aktionlimitform looks this:

$aktionform = new aktionform($this->getoption('aktion'), array("limit" => true));  $this->embedform('aktion', $aktionform);    $this->widgetschema['neuerwert']= new sfwidgetforminputtext();

the embedded aktionform has 1 element (a dropdown-box includes unique names of objects of „aktion“):

$this->widgetschema['name'] = new sfwidgetformchoice(array('choices' =>   aktionpeer::gettypes()),array('onchange' => '???'));

whenever user chooses „aktion“ in dropdown-box want load current object „aktion“ (referenced name) in executeindex , show values (value 1-3) in indexsuccess.(when submitting leads action.)

i need function calls executeindex in onchange-event. have declare function in web/js-folder, right?. how call function form? , how call action in javascript-function?

i hope understood i've written – today have difficulties explain problem in english :) help?

first of all, consider upgrading symfony 2.

then, don't need configure in form type, if decide use jquery (nice javascript framework). jquery can bind events elements easy.

$(document).ready( function() {     $('#id_of_the_form_field').change(function() {         // selected value         var selected = $(this).val()          // magic pony stuff     }); });

to call php actions javascript, need make ajax request related route.

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).
