I have a standard css/jquery menu where I use addClass/removeClass to set whatever li
I am on to '开发者_Go百科current'. However, the code to do this uses $(this)
. I want to also do this same set of procedures from links not in the menu. For example, I would like the menu 'active' flag to be in the right place after following a page link that is somewhere buried in the page content and not in the menu itself.
Menu HTML
<ul class="nav2">
<li class="current"><a href="#tab-1" rel="panel">Page one</a></li>
<li><a href="#tab-2" rel="panel">Page two</a></li>
<li><a href="#tab-3" rel="panel">Page three</a></li>
<li><a href="#tab-4" rel="panel">Page four</a></li>
</ul>
Page HTML
<p>Herein you will find a further description of
<a href="#tab-2" rel="panel">page two</a>.
Javascript
$('a[rel=panel]').click(function (e) {
$('a[rel=panel]').parent('li').removeClass('current');
$(this).parent().addClass('current');
//$("a [href='" + $(this).attr('href') + "']").parent('li').addClass('current');
});
(The commented out line is my failed attempt to make the "secondary" link act just like the "primary" link in the menu.)
Help? Thanks!
This should work:
$('a[rel=panel]').click
(
function (e)
{
$('.current').removeClass ('current');
var Targ = $(e.target).attr ('href');
if (Targ)
$("ul.nav2 a[href*='" + Targ + "']").parent ().addClass ('current');
}
);
.
See it in action at jsbin.
As the link (a
element) inside the content has no list item (li
) element as parent (it is p
and you don't show further ancestors), it should just be:
$("a [href='" + $(this).attr('href') + "']").addClass('current');
But that assumes that you defined you CSS accordingly and the class current
has effects when attached to a link element.
$('a[rel=panel]').click(function (e) {
$('a[rel=panel]').parent('li').removeClass('current');
// $(this).parent("li").addClass('current');
$(".nav2 a[href='" + $(this).attr('href') + "']").parent('li').addClass('current');
});
this worked fine over at:

let me know if you need more in this one.
Thanks for the help, I see what you guys are doing, but it isn't working for what I need.
@ Felix: I need to set 'current' class for the parent (li) not for (a). Also this is all just 1 page. I am using jquery scrollTo to slide things around onClicks.
@ Brock: Your example works perfectly, however:
I am trying to use this in conjunction with jquery lavalamp, and even though the 'current' class gets correctly applied to the right (li) I still cannot get the visual current indicator to stick to the right menu item.
More fully, my code in (head) is:
<script type="text/javascript" src="js/jquery-1.4.1.min.js"></script>
<script type="text/javascript" src="js/jquery.easing.min.js"></script>
<script type="text/javascript" src="js/jquery.lavalamp.min.js"></script>
<script type="text/javascript" src="js/jquery.scrollTo-1.4.2-min.js"></script>
<script type="text/javascript" src="js/scrollto.js"></script>
<script type="text/javascript">
$(function() {
$(".nav2").lavaLamp({fx: "backout", speed: 500, click: function(event, menuItem) {
return true;
} }); });
</script>
where scrollto.js contains
$(document).ready(function() {
//Get the height of the first item
$('#mask').css({'height':$('#tab-1').height()});
//Calculate the total width - sum of all sub-panels width
//Width is generated according to the width of #mask * total of sub-panels
$('#panel').width(parseInt($('#mask').width() * $('#panel div.tab').length));
//Set the sub-panel width according to the #mask width (width of #mask and sub-panel must be same)
$('#panel div.tab').width($('#mask').width());
//Get all the links with rel as panel
$('a[rel=panel]').click(function (e) {
//Get the height of the sub-panel
var panelheight = $($(this).attr('href')).height();
//Resize the height
$('#mask').animate({'height':panelheight},{queue:false, duration:500});
//Scroll to the correct panel, the panel id is grabbed from the href attribute of the anchor
$('#mask').scrollTo($(this).attr('href'), 800);
//Set class for the selected item
//.parent() added for toggling li classes instead of a classes
//$('a[rel=panel]').parent('li').removeClass('current');
$('.current').removeClass ('current');
//$(this).parent().addClass('current');
var Targ = $(e.target).attr ('href');
if (Targ) {
$("ul.nav2 a[href*='" + Targ + "']").parent ().addClass ('current');
}
//Discard the link default behavior
//return false;
e.preventDefault();
});
$('#mask').scrollTo('#tab-1', 400 );
});
Thanks for any further help!
