Limiting area of page scroll on navigation click

I am using the following jquery code to scroll to particular sections when a menu in the navigation tab is clicked. You must have well guessed by now that its a one page website. So coming further, the problem is that when the menu is clicked it scrolls to that particular DIV section but the header hides behind the menu's div. I mean it scrolls way too much up. I want to limit the level of scrolling. Say the it should stop 200px before than what it actually reaches a stop point now. Is it possible?
Here is my code
$(document).ready(function() {
$('body').find('a').click(function(){
var $href = $(this).attr('href');
var $anchor = $($href).offset();
var $li = $(this).parent('li');
$li.addClass('active');
$li.siblings().removeClass('active');
$('body,html').animate({ scrollTop: $anchor.top }, 1000);
return false;
});
});

Instead of hard coding the header value, a better approach would be dynamically getting the height of header, so it won't create issues in mobile and other devices.
$(document).ready(function() {
$('body').find('a').click(function(){
var $heightEx = $('.navbar').height(); // use your respective selector
var $href = $(this).attr('href');
var $anchor = $($href).offset();
var $li = $(this).parent('li');
$li.addClass('active');
$li.siblings().removeClass('active');
$('body,html').animate({ scrollTop: ($anchor.top - $heightEx) }, 1000);
return false;
});
});
EDIT
This is the code I personally use
$("a").on('click', function(event) {
$heightEx = $('header').height();
if (this.hash !== "") {
event.preventDefault();
var hash = this.hash;
$('html, body').animate({
scrollTop: ($(hash).offset().top - $heightEx)
}, 800);
}
});

Maybe, you need to change 'animate' scrollTop parameter:
$('body,html').animate({ scrollTop: $anchor.top - 200px }, 1000);

How to integreate two codes with delay?

i have this code to animate my page with anchors
$('a[href*=#]').click(function(){
$('html, body').animate({
scrollTop: $( $.attr(this, 'href') ).offset().top
}, 500);
return false;
});
And this other code to make a delay when the link is presed
function delay (URL) {
setTimeout( function() { window.location = URL }, 500 );
}
So when i have a link with demo the first code runs perfeclty but when i add the delay like this <a onclick="delay ('#contentexpand-1')">demo</a> the first code doesn't work just jump to the anchor.
Please help me! thanks in advance :)

The problem is that your animation is attached to <a> tags. That does not get triggered when you simply set the window location. The solution is to trigger the animate both ways:
// Smoothly scroll to a tag defined by <a name="anchorName">
function scrollTo (anchorName) {
$('html, body').animate( {
scrollTop: $( "a[name=" + anchorName + "]" ).offset().top
}, 500);
}
// Make all # anchors scroll smoothly to their targets
$(document).ready(function(){
$('a[href*=#]').click(function() {
var anchorName = $(this).attr('href').substr(1); // strip off #
scrollTo(anchorName);
return false;
});
});
// Scroll to an anchor after half a second
function delay (anchorName) {
setTimeout( function() { scrollTo(anchorName); }, 500 );
}
I am not convinced that your code for finding the offset was right so I adjusted it a bit to make it clearer.
The tag you want to scroll to is defined like this:
<a name="demo">demo</a>
Then you can choose either behaviour:
scroll smoothly to demo immediately
<a onclick="delay ('demo')">scroll smoothly to demo after half second delay</a>

Bootstrap scrolling navbar issues

The website I'm working on: zarwanhashem.com
You can find my previous question (which includes my code) here: Bootstrap one page website themev formatting problems
The selected answer solved my issues but I have another problem because of the jQuery adjustment with the -50. Now the navbar incorrectly indicates the page I am on. i.e. The navbar is supposed to darken the section that you are currently in. So if you click "about" it will take you to the about page and darken the about link in the navbar. But the link BEFORE the page you are on is highlighted because the -50 makes the navbar think that it is on the previous section. You can easily try this to see what I mean.
How can I fix this? Thanks. The reason I didn't add this onto my old question is because the person stopped looking at it.
Also please keep your explanations simple/dumb them down a little for me. I know very basic HTML and CSS, and I don't know any Javascript.
scrolling js:
//jQuery to collapse the navbar on scroll
$(window).scroll(function() {
if ($(".navbar").offset().top > 50) {
$(".navbar-fixed-top").addClass("top-nav-collapse");
} else {
$(".navbar-fixed-top").removeClass("top-nav-collapse");
}
});
//jQuery for page scrolling feature - requires jQuery Easing plugin
$(function() {
$('a.page-scroll').bind('click', function(event) {
var $anchor = $(this);
$('html, body').stop().animate({
scrollTop: $($anchor.attr('href')).offset().top -50
}, 1500, 'easeInOutExpo');
event.preventDefault();
});
});
js added at end of document as suggested by poster in previous question:
$(window).ready(function(){
$('div[class^="content-section"]').css('min-height', $(window).height());
})

You are putting the .active class on the wrong element somehow. You need to put the .active class on the clicked element. You should handle the active state with js. This is my solution based on your HTML structure but I'm sure there are different solutions as well.
$(document).on('click', '.page-scroll', function(event) {
var clicked = event.target; //get the clicked element
if($(clicked).closest('ul').hasClass('dropdown-menu')){ //check if clicked element is inside dropdown
$(clicked).closest('ul').parent().siblings().removeClass('active'); //remove active class from all
$(clicked).closest('ul').parent().addClass('active'); add active class on clicked element parent - in your case <li> tag.
}else{
$(clicked).parent().siblings().removeClass('active');
$(clicked).parent().addClass('active');
}
}
Let me know if this works for you.
EDIT after you posted your code
Try replacing your function with this:
$(function() {
$('a.page-scroll').bind('click', function(event) {
var $anchor = $(this);
$('html, body').stop().animate({
scrollTop: $($anchor.attr('href')).offset().top -50
}, 1500, 'easeInOutExpo');
if($($anchor).closest('ul').hasClass('dropdown-menu')){
$($anchor).closest('ul').parent().siblings().removeClass('active');
$($anchor).closest('ul').parent().addClass('active');
}else{
$($anchor).parent().siblings().removeClass('active');
$($anchor).parent().addClass('active');
}
event.preventDefault();
});
});

here is a work around this problem.
just change the contents of your scrolling-nav.js to the following:
//jQuery to collapse the navbar on scroll
$(window).scroll(function() {
if ($(".navbar").offset().top > 50) {
$(".navbar-fixed-top").addClass("top-nav-collapse");
} else {
$(".navbar-fixed-top").removeClass("top-nav-collapse");
}
});
//jQuery for page scrolling feature - requires jQuery Easing plugin
$(function() {
$('a.page-scroll').bind('click', function(event) {
var $anchor = $(this);
$('html, body').stop().animate({
scrollTop: $($anchor.attr('href')).offset().top -50
}, 1500, 'easeInOutExpo', function(){
$('ul.navbar-nav li, ul.dropdown-menu li').removeClass('active');
$($anchor).parent('li').addClass('active');
});
event.preventDefault();
});
});

Selection and focus on element of webpage not working (offset)

My question is a little tricky to explain, but I will try anyway. I have two horizontal tabs which, when you click on them, open a text box content. I'm trying to "focus" on them when they get clicked on. I've found a lot of material online but nothing works except for this code I'm showing below:
$(".accordionButton").click(function() {
$('html, body').animate({
scrollTop: $(this).offset().top
}, 500);
});
$(".accordionButtonone").click(function() {
$('html, body').animate({
scrollTop: $(this).offset().top
}, 500);
If I only click on the first accordionButton it works. If I click on the second accordionButton for first, it works. If I click on the first accordionButton after I've clicked on the second it works, but if I click on the second accordionButton after I click on the first it doesn't work: the focus remains at the bottom of the page. I don't know what could be the problem, I'm making some attempt with the animate function (jQuery tutorial) and the offset function (jQuery tutorial) but I would be grateful even only to know what is going wrong...
UPDATE: a partial solution is
$(".accordionButton").click(function() {
$('html, body').animate({
scrollTop: $(this).offset().top
}, 500);
});
$(".accordionButtonone").click(function() {
$('html, body').scrollTop(0);
});

$(".accordionButton").click(function() {
$('html, body').animate({
scrollTop: $(this).nextAll('div .accordionContent').offset().top
}, 500);
});
$(".accordionButtonone").click(function() {
$('html, body').animate({
scrollTop: $(this).nextAll('div .accordionContentone').offset().top
}, 500);
})
You have to put all that into a callback
$('.accordionContent').slideUp('normal', function(){
$(".accordionButtonone").click(function() {
$('html, body').animate({
scrollTop: $(this).nextAll('div .accordionContentone').offset().top
}, 500);
})
});

The solution is NOT elegant, but it works:
$(".accordionButton").click(function() {
$('html, body').animate({
scrollTop: $(this).offset().top
}, 10);
});
$(".accordionButtonone").click(function() {
$('html, body').scrollTop(458);
});

You are making it scroll down by using offset. remove the offset and it will stop scrolling down. also, instead of using individual selectors, why don't you write some code that utilizes jquery's 'this'
$(this)

jquery scrolling won't scroll from exact location

I'm using the following jquery to make my links scroll to the next div. However, I've run into a problem. From the top of the page the script works fine. As soon as I click a link from another div (another link further down the page) the script only scrolls so far either up or down but not to the next specified div. How can I make the script scroll fully from the current location of where the link is located?
$(function() {
$('#nav a').bind('click',function(event){
var $anchor = $(this);
$('html, body, #container, .main').stop().animate({
scrollTop: $($anchor.attr('href')).offset().top
}, 1500,'easeInOutExpo');
event.preventDefault();
});
});

You have a error here:
scrollTop: $($anchor.attr('href')).offset().top
//------^^^^^^^---------------------------------this itself a selector
change to this and try with:
scrollTop: $anchor.attr('href').offset().top
or this one too:
$('#nav a').bind('click',function(event){
var $anchor = $(this).attr('href');
$('html, body, #container, .main').stop().animate({
scrollTop: $($anchor).offset().top
}, 1500,'easeInOutExpo');
event.preventDefault();
});
CHECKOUT IN FIDDLE

You're not calling the correct spot...
this should do the trick... Set the anchor point first.
$(function() {
$('#nav a').bind('click',function(event){
var $anchor = $(this).attr('href');
$('html, body, #container, .main').stop().animate({
scrollTop: $($anchor).offset().top
}, 1500,'easeInOutExpo');
event.preventDefault();
});
});

ok, so I've made you a JSFiddle, the js-code I rewrote to the code below, but you can have a have a look at the full thing here: http://jsfiddle.net/re7Xc/
$(function() {
$('a.scrolltonext').click(function(event){
event.preventDefault();
var parentblock = $(this).parent();
var nextblock = parentblock.next();
//nextblock.css('background-color','#00f');
if(nextblock.size()>0) {
$('html, body').stop().animate({
'scrollTop': nextblock.offset().top
}, 800);
}
});
});
the catch in this script though is that I put the links in the div itself, so it's not in a #nav somewhere. So you'd have to rewrite that part if you put the links in your #nav!
I put an if-statement in there as well, because I thought it'd be better if you check if there is a next-div first, before scrolling there.
Hope it makes some sense, and let me know if it works for you!
cheers
