css - jQuery mobile show loader for custom loading process? -


i'm building web application rich in images , interactive elements. these reasons want display page once images loaded:

$(document).on('pageinit', function(){     $('.ui-content').hide();     var imgs = $(".ui-content img").not(function() { return this.complete; });     var count = imgs.length;     if (count) {         imgs.load(function() {             count--;             if (!count) {                 $(".ui-content").show()             }         });     } else {         $(".ui-content").show();     } });

i need either a) remove loader , replace own, or b) have loader stay until above function finishes.

how either remove loader or keep until not needed?

jquery mobile custom loader

solution:

working jsfiddle: http://jsfiddle.net/gajotres/vdgb5/

mobileinit event must initialized before jquery mobile initialized , after jquery. additional changes css must done work.

first of all, need override default ui-loader-default class because opacity low , final spinner hard see. change opacity value how ever want.

.ui-loader-default {     opacity: 1 !important;       }

and our spinner. 

.custom-spinner {     width: 37px !important;     height: 37px !important;     background-image:url('http://pictures.reuters.com/clientfiles/rtr/images/ajax-loader.gif');     display: block; }

here's working example:

code example

html:

<!doctype html> <html>     <head>         <title>jqm complex demo</title>         <meta name="viewport" content="width=device-width; initial-scale=1.0; maximum-scale=1.0; minimum-scale=1.0; user-scalable=no; target-densitydpi=device-dpi"/>         <link rel="stylesheet" href="http://code.jquery.com/mobile/1.2.0/jquery.mobile-1.2.0.min.css" />         <style>              .ui-loader-default {                 opacity: 1 !important;                   }              .custom-spinner {                 width: 37px !important;                 height: 37px !important;                 background-image:url('http://pictures.reuters.com/clientfiles/rtr/images/ajax-loader.gif');                 opacity: 1 !important;                 display: block;             }         </style>         <script type="text/javascript" src="http://www.dragan-gaic.info/js/jquery-1.8.2.min.js"></script>         <script>             $( document ).bind( 'mobileinit', function(){                 $.mobile.loader.prototype.options.text = "loading";                 $.mobile.loader.prototype.options.textvisible = false;                 $.mobile.loader.prototype.options.theme = "a";                 $.mobile.loader.prototype.options.html = "<i class='custom-spinner'></i>";             });          </script>                <script src="http://code.jquery.com/mobile/1.2.0/jquery.mobile-1.2.0.min.js"></script>             <script>             $(document).on('pageshow', '#index', function(){                         $.mobile.loading( 'show');                       });          </script>     </head>     <body>         <div data-role="page" id="index">             <div data-theme="a" data-role="header">                 <h3>                     first page                 </h3>                 <a href="#second" class="ui-btn-right">next</a>             </div>              <div data-role="content">              </div>              <div data-theme="a" data-role="footer" data-position="fixed">              </div>         </div>      </body> </html>

$(document).on('pagebeforecreate', '#index', function(){          var interval = setinterval(function(){         $.mobile.loading('show');         clearinterval(interval);     },1);     });  $(document).on('pageshow', '#index', function(){       var interval = setinterval(function(){         $.mobile.loading('hide');         clearinterval(interval);     },1);       });

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).
