How Do I Use Scrollspy when I have links on the page and off the page?

I have an application with a landing page that has many sections, and use Scrollspy for the smooth scrolling effect in the page. At the end of my navigation items I have a call to action button that takes the user to another page. However, because it's in my navigation items, when the page loads, Scrollspy is throwing an error on the link to another page.
Uncaught Error: Syntax error, unrecognized expression: https://example.com/page2
Is there anything I can do to tell scrollspy to ignore that link or is there some other way to get rid of that error? Thanks!
Here is the code I am using to initialize scrollspy:
(function ($) {
'use strict';
// SmoothLink
function initSmoothLink() {
$('.nav-item a').on('click', function(event) {
var $anchor = $(this);
$('html, body').stop().animate({
scrollTop: $($anchor.attr('href')).offset().top - 0
}, 1500, 'easeInOutExpo');
event.preventDefault();
});
}
// StickyMenu
function initStickyMenu() {
$(window).on('scroll',function() {
var scroll = $(window).scrollTop();
if (scroll >= 50) {
$(".sticky").addClass("stickyadd");
} else {
$(".sticky").removeClass("stickyadd");
}
});
}
// Scrollspy
function initScrollspy() {
$("#navbarCollapse").scrollspy({
offset: 70
});
}
//MFPVideo
function initMFPVideo() {
$('.video_play').magnificPopup({
disableOn: 700,
type: 'iframe',
mainClass: 'mfp-fade',
removalDelay: 160,
preloader: false,
fixedContentPos: false
});
}
// Back To Top
function initBackToTop() {
$(window).on('scroll',function(){
if ($(this).scrollTop() > 100) {
$('.back_top').fadeIn();
} else {
$('.back_top').fadeOut();
}
});
$('.back_top, .footer_logo_link').on('click',function(){
$("html, body").animate({ scrollTop: 0 }, 1000);
return false;
});
}
function init() {
initSmoothLink();
initStickyMenu();
initScrollspy();
initMFPVideo();
initBackToTop();
}
$(document).on('turbolinks:load', function(){
init();
});
})(jQuery);

You can add in if statement to check if the href has a hash. If it doesn't have one, then it will just proceed as normal.
function initSmoothLink() {
$('.nav-item a').on('click', function(event) {
var $anchor = $(this);
if (this.hash !== "") {
$('html, body').stop().animate({
scrollTop: $($anchor.attr('href')).offset().top - 0
}, 1500, 'easeInOutExpo');
event.preventDefault();
}
});
}

Scrollspy looks for all a tags in given container, takes href attribute and uses it's value as jQuery selector. Here is the possible solution using JS:

Setting href and id is required in your case if you don't want to add additional checks in initSmoothLink() function.

scroll-to-top button on a mobile website

I'm trying to make the Scroll To Top button appear once the user started scrolling down, instead of it always being present, even when being at the top. Quick note, I barely have experience with JS, so I have no idea what I'm doing.
Anyway here is the page I'm having an error on: http://www.m.evans-carpentry.com/gallery/projects/
<script>
$(function() {
var $elem = $('#content');
$('#nav_up').fadeIn('slow');
$('#nav_down').fadeIn('slow');
$(window).bind('scrollstart', function(){
$('#nav_up,#nav_down').stop().animate({'opacity':'0.2'});
});
$(window).bind('scrollstop', function(){
$('#nav_up,#nav_down').stop().animate({'opacity':'1'});
});
$('#nav_down').click(
function (e) {
$('html, body').animate({scrollTop: $elem.height()}, 800);
}
);
$('#nav_up').click(
function (e) {
$('html, body').animate({scrollTop: '0px'}, 800);
}
);
});
</script>
Thanks!

you call jquery earlier announcements of jquery on line 30
<script>$('#nav Li: has (ul)').doubleTapToGo ();</script>
insert this line after the call jquery

Your code is too complex, try this:
$(document).ready(function(){
//Check to see if the window is top if not then display button
$(window).scroll(function(){
if ($(this).scrollTop() > 100) {
$('.scrollToTop').fadeIn();
} else {
$('.scrollToTop').fadeOut();
}
});
//Click event to scroll to top
$('.scrollToTop').click(function(){
$('html, body').animate({scrollTop : 0},800);
return false;
});
});
".scrollToTop" is the thing to be clicked that scrolls back to the top of the page.

jQuery scroll does not scroll up

I have this code below and the DEMO fiddle.
jQuery(document).ready(function () {
$(window).scroll(function () {
$('html, body').animate({
scrollTop: $('#content').offset().top
}, 1000);
});
});
I'm really confused why I can't scroll up? Anybody can explain to me why and please share some solutions you have.
Any help, is very appreciated.

Alright, this should do what you are asking for. I don't think it is very user friendly, but that is up to you.
Demo Fiddle
//this prevents the animate method from running multiple times.
var scrolling = false;
jQuery(document).ready(function () {
$(window).scroll(function () {
if ( $(window).scrollTop() <= 100 && scrolling === false) {
//set to true to prevent multiple scrolls
scrolling = true;
//run the animation
$('html, body').animate({
scrollTop: $('#content').offset().top
}, 1000, function() {
//when animation is complete, set scrolling to false
scrolling = false;
});
}
});
});

You can't scroll up because your code is wrapped in the scroll() function so it basically locks its position every time you try and scroll with either the mouses scroll wheel or arrow keys. If you amend to the following then it will position itself accordingly when the page first loads.
jQuery(document).ready(function () {
$('html, body').animate({
scrollTop: $('#content').offset().top
}, 1000);
});

Are you trying to have it animate when the link is clicked? If so you need to change your code:
jQuery(document).ready(function () {
$('a').click(function () {
$('html, body').animate({
scrollTop: $('#content').offset().top
}, 1000);
});
});
I would probably add a class or ID value to your link so you can target that one specific link. The code above would apply to all links on your page...although right now there is only the one.
<h1>Scroll to the Content</h1>
jQuery(document).ready(function () {
$('.scrollToContent').click(function () {
$('html, body').animate({
scrollTop: $('#content').offset().top
}, 1000);
});
});

I'm not sure if you will satisfied on this but i found something that can help a little on my problem.
jQuery(document).ready(function () {
$(this).bind('mousewheel', function(e){
if(e.originalEvent.wheelDelta /120 < 1) {
$('html, body').delay(200).animate({
scrollTop: $('#content').offset().top
}, 1000);
}
});
});
DEMO

No need to add the jquery functionality to achieve the requirement that has been asked. Please remove the Jquery code and run the code snippet provided in the fiddle. It is behaving as per the requirement.

scroll down function on click

below is the code I have for scrollTop. It works fine when I target a specific pixel, but I want to scroll down 300px, instead of scrollTop a certain div on click. can anyone help?
<div id="button"></div>
<div1 style="height:300px;">img1</div>
<div2 style="height:300px;">img2</div>
<div3 style="height:300px;">img3</div>
<div4 style="height:300px;">img4</div>
$(function() {
$("#button").on("click", function() {
$("html, body"). animate({"scrollTop":$().offset().top-300}, 1000);
return false;
});
});

Try using window.scrollBy(0,300);

$().offset().top doesnt do much of anything. Replace it with window.scrollY
$(function() {
$("#button").on("click", function() {
$("body").animate({"scrollTop": window.scrollY-300}, 1000);
return false;
});
});
Also negative is up and positive is down when we're talking about scrolling so you probably want to add 300 instead.

I think it's the best way.
var body = $('html, body');
$('#button').click(function() {
var n = $(document).height() - $(window).height();
body.stop().animate({scrollTop: n }, 1000, function() {
});
});
