jQuery -- Prevent User from Scrolling Up Past Certain Scroll Height

I am making a one-page website.
Basically, I have this animated landing page with a landing image and a bootstrap jumbotron. I want to be able to implement a function where once the user scrolls past the end of the jumbotron, the user cannot scroll back up to view the landing image and the jumbotron. In a sense, either hide or delete the <div>s that were at the top, or completely disable scrolling back to those points.
I found this code, but it automatically disables scrolling up to the page top (after 200 px) on page load:
$(function() {
var scrollPoint = 200;
$(window).scroll(function() {
$(window).scrollTop() < scrollPoint ?
$(window).scrollTop(scrollPoint) : '';
}).scroll();
});
Any ideas?

You can use this code to hide the jumbotron.
$(window).bind('scroll', function() {
if($(window).scrollTop() >= $('#id_of_jumbotron').offset().top +
$('#id_of_jumbotron').outerHeight() - window.innerHeight) {
hideTheJumboTron();
}
});

try this:
$(function () {
var scrollPoint = 200;
$(window).scroll(function () {
if ($(window).scrollTop() < scrollPoint) {
console.log($(window).scrollTop());
$(window).scrollTop(scrollPoint)
return false;
}
}).scroll();
});

fadeOut on scroll at pixel height

i'm trying to achieve a Scroll to Top button that fades in at a certain point on the page and fades out at a certain point...I have the fadeIn function working properly but can't seem to get the proper syntax for the click event fadeOut; it just disappears once you get to the top, instead of fading out if you're <= 675px. Any help is greatly appreciated!
HTML:
</div>
BACK TO LOGIN
</div>
jQuery:
$(document).ready(function() {
//Check to see if the window is top if not then display button
$(window).scroll(function() {
if ($(this).scrollTop() > 675) {
$('.scrollToTop').fadeIn(500);
} else {
$('.scrollToTop').fadeOut(500);
}
});
//Click event to scroll to top
$('.scrollToTop').click(function() {
$('html, body').animate({
scrollTop : 0
}, 800);
return false;
});
});

I think your question isn't so clear but maybe you mean that when click on the scrollToTop button it doesn't disappear until the scroll reach to top of page, it's because when your animation function is running the .scroll can't runs so fast that disappear button when reach to 675px but you can fadeout button as soon as click on it using this code:
jQuery: $(document).ready(function() {
var isClicked = false;
$('.scrollToTop').css("display","none");
$(window).scroll(function() {
if (isClicked == false){
if ($(this).scrollTop() > 675) {
$('.scrollToTop').fadeIn(500);
} else {
$('.scrollToTop').fadeOut(500);
}
}
});
$('.scrollToTop').click(function() {
isClicked = true;
$('.scrollToTop').fadeOut(500);
$('html, body').animate({
scrollTop : 0
}, 800, function(){
isClicked = false;
});
});
});
The isClicked variable is added to prevent blinking button (you can remove it to figure out what i'm saying).
Also i add this line:
$('.scrollToTop').css("display","none");
because it seems that you don't need a "Scroll To Top" button when page load for first time and you are on the top of page.

jQuery scrolling to a certain point on scroll event

At my page, i have a few booleans in my script, to check if the first screen is activated, and the same thing for the second screen. Screen 1 fills up the whole screen.
It looks something like this:
var headerLoaded = true,
contentLoaded = false;
When i scroll, i want the page to scroll automaticly to the 'content' area of my webpage. And i had this code for it:
$(window).scroll(function() {
if (($(window).scrollTop() > 0) && (!contentLoaded && headerLoaded)) {
$('html, body').animate({
scrollTop: $('#content').offset().top
}, 500, function() {
contentLoaded = true;
headerLoaded = false;
});
}
});
It checks if im not at the top of the page, and for the 2 booleans.
The function works great, but it's still calling the
$('html, body').animate({
scrollTop: $('#content').offset().top
}, 500, function() {
contentLoaded = true;
headerLoaded = false;
});
part when i'm scrolled down to the 'content' div.
So everytime i scroll when im at the 'content' div, its scrolling back to the top of that.
Btw, both of the div's are absolute.

So, the animate is calling your original $(window).scroll(...) over and over.
Try telling your main scroll listener not to start animating if its already animating.
var animating = false;
$(window).scroll(function() {
if (!animating && $(window).scrollTop() > 0 && !contentLoaded && headerLoaded) {
animating = true;
$('html, body').animate({
scrollTop: $('#content').offset().top
}, 500, function() {
animating = false;
contentLoaded = true;
headerLoaded = false;
});
}
});
wait.. i just read it..
You're just locking the screen at the content... why animate at all?
The answer I was giving was saying the animating the scroll will also trigger the main scroll, resulting in an endless loop... but what are you trying to do in the first place?

Assign top value to scrollTop

I have a project where the logo will load in the center of the page when the user comes to the website. Then, if the user scrolls down, the logo will scroll to the top and the content will follow, but, the logo will become fixed on top once it reaches top of the window. So, what I want to do is, stop the content from going to the top (because that content goes behind the logo), e.g. #Furniture is the div, that goes to top when an anchor tag with href"#Furniture" is clicked. I want to stop the div containing #Furniture at 150px (logo's height) from top of the browser. Is that possible?
Following is the code that I have used for smooth scrolling of any div to the top:
$(window).load(function () {
var $root = $('html, body');
$('a').click(function () {
var href = $.attr(this, 'href');
$root.animate({
scrollTop: $(href).offset().top
}, 500, function () {
window.location.hash = href;
});
return false;
});
});
Fiddle

Use like this:
var top_val = $(href).offset().top; // or anything your code for getting top value
$root.animate({
top: "+top_val+"
}, 500, function () {
window.location.hash = href;
});

How to scroll page on multiple ID in js

Please check what i did yet http://jsfiddle.net/dUVmh/1/ .
About the animation i want to achieve is that:
When you first scroll down the page then window scroll to #green DIV. After that if you again scroll down window scroll to #yellow DIV & same at the time of scrollup (fom #yellow to #green).
About the issue:
You can see the animation it's stuck on #green DIV.
$(window).scroll(function(){
if($(this).scrollTop() > 0) {
$("html, body").animate({ scrollTop: $('#green').offset().top }, 1000);
}
else if($(this).scrollTop() > 1000) {
$("html, body").animate({ scrollTop: $('#yellow').offset().top }, 1000);
}
else{
$("html, body").animate({ scrollTop: $('#red').offset().top }, 1000);
}
});
I didn't have much experience in JS.
Thanks i advance :)

This was a fun problem to work on.
This solution places the divs into an array, and remembers the array index of the element that was last scrolled to. Once a scroll event is triggered it checks to see if the new scrollTop is above or below the current divs top offset and moves to the next or previous div in the array accordingly.
This solution allows you to have many divs. I tried to remove the flickering you get when you scroll to fast, but the only way to do that I believe would be to disable the scrollbars during animation.
http://jsfiddle.net/dUVmh/35/
$(function() {
var divs = [],
body = $('body, html'),
currentDiv = 0,
timeout;
$('div').each(function() {
divs.push($(this));
});
// we only need to capture the first scroll event triggered and then
// add another listener once we have done our animation
var scrollListen = function() {
$(window).one('scroll', function() {
doScroll($(this).scrollTop());
});
};
// Without the timeout, the scroll event would be triggered again too soon
var scrollEnd = function() {
clearTimeout(timeout);
timeout = setTimeout(function() {
scrollListen();
}, 10);
};
// checks if the scroll direction was up and down and animates
// the body scrollTop to the next or previous div
var doScroll = function(scrollTop) {
var direction = scrollTop - divs[currentDiv].offset().top;
if (direction > 0 && currentDiv + 1 < divs.length) {
nextDiv = currentDiv + 1;
} else if (currentDiv - 1 > -1) {
nextDiv = currentDiv - 1;
}
if (currentDiv === nextDiv) {
scrollEnd();
}
body.animate({
scrollTop: divs[nextDiv].offset().top
}, 1000, function() {
currentDiv = nextDiv;
scrollEnd();
});
};
scrollListen();
});
Edit: Firefox scrollTop required to be changed on html and not body. Also fixed a problem with firefox calling scrollListen more than once at a time.

The problem is that the $(window).scroll(function()) gets called over and over again when scrolling through the ScrollTop animation with jQuery.
Here is a possible solution that checks if it is currently scrolling or not and only executes the ScrollTop animation once.
http://jsfiddle.net/dUVmh/29/
Side note: It might be a good idea to check which direction the user is scrolling (up or down) and depending on that scroll to the next div to the top or to the down.
You can check that be saving the last scrollTop position and comparing it with the current one.
UPDATE: Here's a solution that takes the scroll direction into account: http://jsfiddle.net/dUVmh/36/
