jquery mobile - Header back button with forced refreshing -


i needed force refreshing using this technique. when navigate new page jqm correctly adds button in header. when go first page button incorrectly appears. possible conditionally create button? have tried manually creating button , conditionally hiding based on parameter in uri seems once button appears can never hide again.

edit: here code demonstrates problem. not not hide custom button when go page 1, doesn't hide "page 1" content when on page 2, or visa versa. seems once has been shown cannot rehidden. 

<html>     <head>         <link rel="stylesheet" href="http://code.jquery.com/mobile/1.3.1/jquery.mobile-1.3.1.min.css" />         <script src="http://code.jquery.com/jquery-1.9.1.min.js"></script>         <script src="http://code.jquery.com/mobile/1.3.1/jquery.mobile-1.3.1.min.js"></script>         <script>             var backbuttonvar = null;             var page1var = null;             var page2var = null;         </script>     </head>      <body>         <div data-role="page" data-add-back-btn="false">             <div data-role="header">                 <h1>test</h1>                 <a id="backbutton" data-role="button" data-direction="reverse" data-rel="back" data-icon="arrow-l" data-iconpos="left">myback</a>             </div>              <div id="page1" data-role="content">                 <a href="index.html?id=2">go page 2</a>             </div>              <div id="page2" data-role"content">                 page 2             </div>              <script>                 $(document).ready(function() {                     jquery(document).on('pagehide', 'div', function(event, ui) {                         var page = jquery(event.target);                         page.remove();                     });                      backbuttonvar = $('#backbutton');                     page1var = $('#page1');                     page2var = $('#page2');                     // root?                     if (window.location.search == '') {                         backbuttonvar.hide();                         page1var.show()                         page2var.hide()                     } else {                         backbuttonvar.show();                         page1var.hide()                         page2var.show()                     }                 });             </script>         </div>     </body> </html>

here fix. give back-button class backbutton. .hide() if active page home page page1, else .show() it.

demo

$('.backbutton').hide(); $(document).on('pagebeforeshow', function () {  var activepage = $.mobile.activepage;  if (activepage[0].id != 'page1') {   $('.backbutton').show();  }  else {   $('.backbutton').hide();  } });

if have question, please let me know.

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).
