JQuery How to select all anchors within current list item?
I wish to, using JQuery, show and hide some anchor tags as I hover over a list item.
How do you loop through the current anchors within a list item using $(this) ?
Here's what I have so far:
$(document).ready(function() {
$('.currentlist > li').mouseover(function(event){
// loop through each anchor tag within this list using $(this)
// and add the .a开发者_运维问答ctive class
});
$('.currentlist > li').mouseout(function(event){
// loop through each anchor tag within this list using $(this)
// and remove the .active class
});
});
a .active
{
display: block;
}
a.edit-icon
{
display: none;
}
a.delete-icon
{
display: none;
}
<ul class="currentlist">
<li><a href="#" class="active">index</a><a href="#" class="edit-icon">edit</a><a href="#" class="delete-icon">delete</a></li>
<li><a href="#" class="active">profile</a><a href="#" class="edit-icon">edit</a><a href="#" class="delete-icon">delete</a></li>
<li><a href="#" class="active">contactus</a><a href="#" class="edit-icon">edit</a><a href="#" class="delete-icon">delete</a></li>
<li><a href="#" class="active">findus</a><a href="#" class="edit-icon">edit</a><a href="#" class="delete-icon">delete</a></li>
</ul>
Try this:
$(document).ready(function() {
$('.currentlist > li').mouseover(function(event){
$(this).find('a').addClass('active');
});
$('.currentlist > li').mouseout(function(event){
$(this).find('a').removeClass('active');
});
});
Where $(this)
refers to hovered li
and $('a', $(this))
context selector is used to find all links inside them and add/remove classes.
You can use .hover()
to shorten the events, .find()
to get the anchors and .addClass()
and .removeClass()
to toggle .active
on and off, like this:
$(function() {
$('.currentlist > li').hover(function() {
$(this).find('a').addClass('active');
}, function() {
$(this).find('a').removeClass('active');
});
});
You'll want to use .hover()
here because mouseover
and mouseout
will fire when entering and exiting children, where mouseenter
and mouseleave
(which .hover()
uses) won't).
Also your CSS needs a fix, this:
a .active
{
display: block;
}
Shouldn't have a space, it should be like this:
a.active
{
display: block;
}
Also, it should be moved to the end so it overrides the .edit-icon
and .delete-icon
definitions.
Here's a working version with all of the above changes.
Something like
$(event.currentTarget).find("a.active").removeClass("active")
should do it for you.
