javascript - Drop down menu hiding menus -


i'm building drop down menu project i'm working on, don't working entirely should. want show sub-menus when hover root-level menus, , close again after short delay when menu or sub-menu not hovered anymore. of works; sub-menus showed when root-level items hovered , hidden when stop hovering root-level item. problem sub-menus hidden when move cursor root-level item sub-menu item other first , hover that. not good, appreciated.

i created jsfiddle code shows issue more clearly.

so, here's code:

menu.htm

<div id=m_wrapper>     <ul id=menu>         <li onmouseover="show_sub_menu('0')" onmouseout="start_timer()">item 1             <div id=s0 onmouseover="show_sub_menu('0')" onmouseout="start_timer()">                 <a href=#>item 1.1</a>                 <a href=#>item 1.2</a>                 <a href=#>item 1.3</a>             </div>         </li>     </ul> </div>

menu.css

#m_wrapper {     position:relative;     display:table; } #menu {     position:relative; } #menu li {     width:100px;     position:relative;     float:left;     list-style-type:none; } #menu div {     position:absolute;     visibility:hidden;     display:inherit;     width:100%;     z-index:30 } #menu div {     position:relative;     display:block;     z-index:35; }

menu.js

var countdown = 300; var timer = null; var menu_item = null;  window.show_sub_menu = function(cath) {     if (menu_item) {         menu_item.style.visibility = 'hidden'; //make sure show 1 menu @ time     }      menu_item = window.document.getelementbyid("s" + cath);     menu_item.style.visibility = 'visible'; //show menu      if (timer) {         window.cleartimeout(timer); //reset timer, menu kept open         timer = null;     } };  window.start_timer = function() {     timer = window.settimeout(close_sub_menu, countdown); };  window.close_sub_menu = function() {     menu_item.style.visibility = 'hidden'; };

you don't have make complex.

ofcourse can same through javascript, see how easy, readable , simple through jquery.

see demo

just use following script

$('#menu li').hover(     function(){             $(this).stop().animate({height: '100px'},1000,function(){});             $(this).find('div').show(600);         }//gets called upon mousehover     ,     function(){             $(this).stop().animate({height: '20px'},1000,function(){});         } //gets called upon mouseout   ); //hover ends

and also, don't know why have written tonns of css. use these:

#menu {     list-style:none; } #menu li {     width:100px;     border:1px solid #ccc;     text-align:center;     cursor:pointer;     height:20px;     overflow:hidden;  } #menu li div {     border:1px solid #ccc; } #s0  {     height:auto; } #s0 {     display:block; }

there's plenty can through it, selected dropdown item. selection through arrow key , not. jquery makes simple you.

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
