jquery - Check if has class -

-

this html:

<div id="gallery">     <div class="item"></div>     <div class="somethingelse"></div>     <div class="item"></div>     <div class="somethingelse"></div>     <div class="item active"></div>     <div class="somethingelse"></div>     <div class="item"></div> </div>

now, each item want add number in div, did this:

function initmenu() {     $( ".gallery-menu" ).html("");     var columns = $('.item').length;     ( var = 0; < columns; i++ ) {         $( ".gallery-menu" ).append( );     } } initmenu();

now simple 0 1 2 3 in gallery-menu div good.

now want check if active. added check this:

function initmenu() {     $( ".gallery-menu" ).html("");     var columns = $('.item').length;     ( var = 0; < columns; i++ ) {         if ($(".item:eq(i)").hasclass('active')) {             $( ".gallery-menu" ).append( + "-active");         } else {             $( ".gallery-menu" ).append( );         }     } } initmenu();

but it's not working.. able point me in right direction?

a cleaner way use jquery's each() function:

$('.item').each(function(i, el){     if ($(this).hasclass('active')) {         $( ".gallery-menu" ).append( + "-active");     } else {         $( ".gallery-menu" ).append( );     } });

i used pyinstaller create standalone exe file pyqt project. did not use single file option because exe created single file option takes long open. therefore, pyinstaller created dist folder contains bunch of files including program.exe file. create setup.exe file place contents of dist folder in program directory , create shortcut in start menu , on desktop. want super simple user. maybe setup.exe files when download program cnet. found inno-setup, looks promising. however, not know if there special considerations because program standalone program create python/pyqt program. thanks! have experience task? there program using task not know about? inno-setup or nsis easiest use. tell them files include , put them , create nice installer you. wrote short tutorial on experiences using innosetup might find helpful: http://www.blog.pythonlibrary.org/2008/08/27/packaging-wxpymail-for-distribution/ note tutorial based around wxpython app wrote, concepts same.
