javascript - How can I make my menu expand all the subitems? -


i have list menu javascript code makes collapse , expand .onclick.

although make show 1 item because every time try new solution for loop or case can't work.

this current code:

<ul id="navigation">     <li class="main"><a>diagonóstico</a></li>     <li class="sub"><a href="javascript:void(0);" class="sub_di1"> › grátis (na compra de qualquer serviço) </a></li>     <li class="main"><a>hardware</a></li>     <li class="sub"><a href="javascript:void(0);" class="sub_ha1"> › instalação/configuração de componentes</a></li>     <li class="sub"><a href="javascript:void(0);" class="sub_ha2"> › instalação/configuração de periféricos </a></li>     <li class="sub"><a href="javascript:void(0);" class="sub_ha3"> › limpeza interna/externa </a></li>     <li class="sub"><a href="javascript:void(0);" class="sub_ha4"> › cooling pack </a></li>     <li class="sub"><a href="javascript:void(0);" class="sub_ha5"> › performance pack </a></li>     <li class="main"><a>software</a></li>     <li class="sub"><a href="javascript:void(0);" class="sub_so1"> › actualização de sistema operativo </a></li>     <li class="sub"><a href="javascript:void(0);" class="sub_so2"> › instalação de sistema operativo </a></li>     <li class="sub"><a href="javascript:void(0);" class="sub_so3"> › instalação de drivers e aplicações </a></li>     <li class="sub"><a href="javascript:void(0);" class="sub_so4"> › configurações de internet e redes wireless </a></li>     <li class="sub"><a href="javascript:void(0);" class="sub_so5"> › legalize o seu pc </a></li>     <li class="main"><a>backup</a></li>     <li class="sub"><a href="javascript:void(0);" class="sub_ba1"> › backup de dados até 4gb </a></li>     <li class="sub"><a href="javascript:void(0);" class="sub_ba2"> › backup , go </a></li>     <li class="sub"><a href="javascript:void(0);" class="sub_ba3"> › suportes danificados </a></li>     <li class="sub"><a href="javascript:void(0);" class="sub_ba4"> › recuperação de dados sem intervenção física </a></li>     <li class="main"><a>segurança</a></li>     <li class="sub"><a href="javascript:void(0);" class="sub_se1"> › remoção de vírus e spyware </a></li>     <li class="sub"><a href="javascript:void(0);" class="sub_se2"> › instalação de anti-vírus </a></li>     <li class="sub"><a href="javascript:void(0);" class="sub_se3"> › configurações de controlo parental </a></li> </ul> 
$(function () {     $("li.sub:not(:first)").hide();     $("li.main a").click(function () {         $("li.sub").slideup("fast");         $(this).parent("li.main").next("li.sub").slidedown("slow");     }); });

here jsfiddle it.

i thinking for loop goes way trough each sub-menu category instance: 

for(var i=1; i<5; i++) {     $(this).parent("li.main").next("li.sub_ha" + i).slidedown("slow"); }

then doing each main menu giving each of them class menu1,menu2,menu3 etc.

next selects next sibling of selected element, can use nextuntil mehod.

$(this).parent().nextuntil("li.main").slidedown("slow");

$(function() {     var $subitems = $("li.sub");     $subitems.not(':first').hide();      $("li.main a").click(function() {         var $targets = $(this).parent().nextuntil("li.main").slidedown("slow");         $subitems.not($targets).slideup("fast");     }); });

Why does Ruby on Rails generate add a blank line to the end of a file? -

running rails generate controller foo home results in: class foocontroller < application controller def home end end (there's nothing on line in actual file, blank line) is there purpose blank line? it's common use newline indicate end of line, last line. many editors (like vi, use) add in newline silently. consensus text files (especially in unix world) should end in newline, , there have been problems historically if wasn't present. why should text files end newline? the tool used count lines in file "wc" counts newlines in file, without trailing newline show 3 instead of 4. it improves readability of templates used in generator. consider: https://github.com/rails/rails/blob/master/railties/lib/rails/generators/rails/controller/templates/controller.rb to remove trailing newline, template have last line of: end<% end -%> instead of: end <% end -%> that seems less readable me. the discussion below refers
