jQuery: Selecting only ul, not ul ul
I'm trying to beat a basic accordion style menu into submission – using jQuery.
Here's the menu:

Here's 开发者_StackOverflow中文版a snippet of code that gives it accordion functionality:
$('#access ul li').click(function(){
$('#access ul ul:visible').slideUp();
$(this).children('ul:hidden').slideDown();
});
The problem: a click on a sub-menu link makes the submenu slide up (and close).
I want to keep the submenu open when the submenu link is clicked, and slide up only when a top level links are clicked.
How can I select only the top level ul with jQuery to animate the submenu? Or is there a way to select the sub-menu link and "tell it" to keep the submenu open on click?
I would appreciate your wisdom!
It seems like you need to use the >
operator in CSS.
.foo > .bar
selects all elements with class bar
that is a direct child of an element with class foo
Got it, working code:
$('#access ul.menu > li > a').click(function(){
$('#access ul ul:visible').slideUp();
$(this).siblings('ul').slideDown();
});
});
To keep the menu from sliding back up again this works:
$('#access ul.menu > li > a').click(function(){
var siblingUl = $(this).siblings('ul');
if(siblingUl.is(':visible')) { // The currently open menu was clicked
// Remove this if you want nothing to happen
siblingUl.slideUp();
return;
}
$('#access ul ul:visible').slideUp();
siblingUl.slideDown();
});
});
You can't stop the menu from closing because the browser is making a new request and loading the menu fresh when you click on the links. Just watch the URL bar. When you click the sub-menu links, the URL changes.
You'll need to add something to the URL to stop the sub-menu from collapsing, or test the URL to see if it should re-open the accordion after the page loads.
This is much simpler and works for me.
$(".parent").click(function() {
$(this).children('ul').slideToggle();
});
i have took 10 minutes to read and understand your code because you have a lot of styles and id's and this is complicating it a lot, take care of the best practices
All you need is something like
<ul>
<li>
<a class="menu">Menu</a>
<ul>
<li><a>Submenu</a></li>
</ul>
</li>
<li>Other menu</li>
</ul>
...
$(document).ready(function(){
$(".menu").click(function(){
$(this).next().toggle()
})
})
