I have created and exact fiddle of my problem here for testing: http://jsfiddle.net/aVBUy/7/
The issue is, when I click on navbar items, I have a script which scrolls to the element id. And I am using scrollspy to highlight the nav elements when page is in correct position. However the scrollspy is only changing the active state when it hits the top of the browser/device. Because my navbar is fixed I need an offset applied to scrollspy to offset by 51px (navbar height).
I've tried everything and I can't get it to work. Please check my fiddle and see if you can find the where I'm going wrong, would help me so much.
Here's my minimised code...
HTML
<div class="navbar navbar-inverse navbar-fixed-top">
<div class="navbar-inner">
<div class="container">
<a class="btn btn-navbar" data-toggle="collapse" data-target=".nav-collapse">
<span class="icon-bar"></span>
<span class="icon-bar"></span>
<span class="icon-bar"></span>
</a>
<a class="brand" href="#"><img src="img/logo.gif" alt="" /></a>
<div class="nav-collapse collapse">
<ul class="nav">
<li><a href="#welcome" data-scroll="#welcome">Welcome</a></li>
<li><a href="#about" data-scroll="#about">About</a></li>
<li><a href="#route" data-scroll="#route">The Route</a></li>
<li><a href="#bike" data-scroll="#bike">The Bike</a></li>
</ul>
</div>

<div class="container">
<div id="welcome" class="row-fluid">
<div class="span12">
<h3>Welcome</h3>

CSS
body {
padding: 51px 0 0;
}
/* Override Bootstrap Responsive CSS fixed navbar */
@media (max-width: 979px) {
.navbar-fixed-top, .navbar-fixed-bottom {
position: fixed;
margin-left: 0px;
margin-right: 0px;
}
}
body > .container {
padding: 0 15px;
}
SCRIPT
var offsetHeight = 51;
$('.nav-collapse').scrollspy({
offset: offsetHeight
});
$('.navbar li a').click(function (event) {
var scrollPos = $('body > .container').find($(this).attr('href')).offset().top - offsetHeight;
$('body,html').animate({
scrollTop: scrollPos
}, 500, function () {
$(".btn-navbar").click();
});
return false;
});
FIDDLE
You need to apply the offset to the body.
$('body').scrollspy({
offset: offsetHeight
});
Also, you will need to subtract at least one from the offsetHeight in the line below, otherwise it will not work when scrolling up.
var scrollPos = $('body > .container').find($(this).attr('href')).offset().top - (offsetHeight - 1);
