Seems like there is something wrong with the if/else statements as the event is actually fired. If you add console.debug("scrollevent fired"); at the beginning of the function and use firebug to show the console log, you will notice that the output is actually written to the output (check the JSFiddle).
Unfortunately I cannot debug your code as I cannot find a couple of elements with the given Id's in your code sample...

This is my first post here so please don't be mad at me if I'm doing something wrong.
Here is the case: Trying to add bootstrap 3 scrollspy functionality into my code on codepen and it's basically not working. Tried different solutions from stackoverflow, etc. and nothing helps.
Is there any good person who can take look into my code?
HTML:
<div class="container-fluid">
<nav class="navbar navbar-default navbar-fixed-top">
<div class="navbar-header">
<button type="button" class="navbar-toggle collapsed" data-toggle="collapse" data-target="#bs-example-navbar-collapse-1" aria-expanded="false">
<span class="sr-only">Toggle navigation</span>
<span class="icon-bar"></span>
<span class="icon-bar"></span>
<span class="icon-bar"></span>
</button>
<a class="navbar-brand" href="#">Patryk Jamróz</a>
</div>
<div class="collapse navbar-collapse" id="bs-example-navbar-collapse-1">
<ul class="nav navbar-nav navbar-right">
<li class="active">About <span class="sr-only">(current)</span></li>
<li>Projects</li>
<li>Contact </li>
</ul>
</nav><!-- navbar -->
<div data-spy="scroll" data-target="#nav" data-offset="0">
<h3 class="text-center" id="about">about</h3>
<h3 class="text-center" id="projects">projects</h3>
<h3 class="text-center" id="contact">contact</h3>
</div>
CSS:
.container-fluid {
padding-right: 15px;
padding-left: 15px;
margin-right: auto;
margin-left: auto;
}
.row {
margin-left: 0;
margin-right: 0;
}
body {
position: relative;
}
In codepen settings tab I included:
CSS:
bootstrap.min.css
JS:
jquery.min.js
bootstrap.min.js
Here is a link to my codepen: https://codepen.io/PatrykJamroz/full/RMZJva
First thing is you need to initiate the body and not a div tag so your body should have the following:
<body data-spy="scroll" data-target=".navbar" data-offset="0">
And not the:
<div data-spy="scroll" data-target="#nav" data-offset="0">
because the body is the thing that the scroll event is attached to so initiating a div does no good unless you are scrolling with that div.
Next you need to attach it the the .navbar or the nav itself would be the best practice. And also I see that you are using jquery 3 and this may cause an issue with bootstrap 3 so you may want to switch to jquery 2.
I think that you don't really undestand how bootstrap scrollspy actually work. You have to make the 'body' as the main scrollspy container! take a look:
$('body').scrollspy({
target: '#bs-example-navbar-collapse-1'
})
$('#scrollDiv').on('activate.bs.scrollspy', function () {
//Do stuff if there is a new event in scrollspy
})
.container-fluid {
padding-right: 15px;
padding-left: 15px;
margin-right: auto;
margin-left: auto;
}
.row {
margin-left: 0;
margin-right: 0;
}
body {
position: relative;
}
<div id="scrollDiv" class="container-fluid" data-spy="scroll" data-target="#bs-example-navbar-collapse-1">
<nav class="navbar navbar-default navbar-fixed-top">
<div class="navbar-header">
<button type="button" class="navbar-toggle collapsed" data-toggle="collapse" data-target="#bs-example-navbar-collapse-1" aria-expanded="false">

In that way it work! Good luck, bye.
u can try whit jquery
$("#yourtarget").click(function() {
$('html, body').animate({
scrollTop: $("#yourDiv").offset().top
}, 2000);
});
https://fiddle.jshell.net/8v72rtxb/
I have the following code.
<div class="menu-horizontal container">
<div class="row menu-container" id="menu">
<div class="col-md-3 menu-item">
<a data-toggle="collapse" class="collapsed collapse-toggle" data-parent="#menu" href="#studies-collapse" aria-expanded="false" aria-controls="collapseExample">

</a>
<div class="collapse" id="studies-collapse">
<div class="container">
<div class="row">
Something...
</div>
</div>
</div>
</div>
<div class="col-md-3 menu-item">
<a data-toggle="collapse" class="collapsed collapse-toggle" data-parent="#menu" href="#research-collapse" aria-expanded="false" aria-controls="collapseExample">

</a>
<div class="collapse" id="research-collapse">
<div class="container">
<div class="row">
Something...
</div>
</div>
</div>
</div>
</div>
</div>
I have no idea why data-parent doesn't work though. Expand one collapse div doesn't close the other collapse. I tried to copy the code from the example of bootstrap, but it still doesn't work.
Also in my project, I include jquery.js before bootstrap.min.js. I have checked some other questions, they said that bootstrap.min.js might have been included twice. But should that be the case?
Thanks for reading!
I figured a workaround for this. Even without using the data-parent attribute.
https://fiddle.jshell.net/zyd1vL4o/
$(document).ready(function(){
$('.collapse').on('show.bs.collapse', function (e) {
$('.collapse').collapse("hide")
})
})

import 'bootstrap/js/dist/collapse';
Include this in your file and the collapse should work.
If its not closing, then you might not be properly linking to to your bootstrap js. You shouldn't need to add anything extra.
check for the following js files:
bootstrap.min.js
bootstrap.bundle.min.js
If you're creating a bootstrap theme then in the functions do this:
wp_register_script( 'write your theme name here', get_template_directory_uri() . '/bootstrap/js/bootstrap.min.js', array( 'jquery' ) );
I tried this link solution but not able to conclude. I am new to this..tried everything but all vain I want something like this what to do

To the link or the button give
data-target = "#idofthepanel"
Refer to the panel using id instead of class
Also,
You have given data-target="#mynavbar" , but navbar is a class and not an id.

I have tried this. but it creates div hide and show. I want dropdown menu in navigation bar.
This is the result of this code
I've searched and searched and can't seem to find my issue. I apologize if this is answered somewhere else. I inherited a "simple" site that needs scrollspy implemented and I can't get anything to work for the life of me.
Here are some excerpts from the code:

Any help would be greatly appreciated as I'm sure it is probably something minor I am overlooking but haven't been able to find in 6 hours of playing with it.
in order to use bootstrap scrollspy your navigation have to be as bootstrap's navigation .
build your NAV as this link below and it will work
http://getbootstrap.com/components/#navbar
try the below example.
$(function(){
$('body').scrollspy({ target: '#myNav' })
})
section > div[id]{
height:800px;
padding-top:50px;
}
