javascript - jQuery, Display none first LI in UL - Stack Overflow-软件玩家 - 软件改变生活!
im just wondering if what I want to do is possible with jQuery...
I have the following...
<ul class="navmenu">
<li>Something</li>
<li>Something</li>
<li>Someting</li>
<li>Something</li>
</ul>
What i want to do is display:none; the first LI within .navmenu, is this possible?

Just use:
$('.navmenu > li:first-child').hide();
jsFiddle Example.
You also may want to check out the jQuery Tutorials and jQuery Selectors API Docs as this is a pretty basic usage of jQuery.
<sarcasm>No, you can't do it. Ever.</sarcasm>
$('.navmenu li:first').hide()
CSS Solution (this should prevent the first element from flickering on page load):
.navmenu > li:first-child {display: none;}
sure,
$('ul.navmenu li:first').css('display', 'none');
You can use a descendant selector, >, to select the li children of the ul with the navmenu class name, then use the first-child pseudo class to select just the first one. Then you can set css styles using the css method:
$("ul.navmenu > li:first-child").css("display", "none")
Live example: http://jsfiddle/uDeQE/1/
Yep, certainly is:
$('.navmenu li:first')
You could also user the pseudo selector in CSS if its styling you're after:
.navmenu li:first-child
