Bootstrap 4 navbar nav-item active class not working
Question
I am quite desperate, I checked every similar questions on stackoverflow and tried many solutions found on google but in vain... I'm really unable to find a working solution to my problem.
I am developping a site with Bootstrap 4 and I have a navbar. When I click on one of the nav-link I want it to have the "active" class, while others stay normal. I might not select the right elements or use wrong jquery/javascript code.
The navbar html code (1) is in a separate header.html file that I load with JS at the beginning of the html page (2) :
(1)
<nav class="navbar navbar-expand-lg navbar-dark bg-dark fixed-top ml-auto">
<div class="container">
<a class="navbar-brand" href="../index.html#"><img src="../images/DSIMB.svg" alt=""></a>
<button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#navbarResponsive" aria-controls="navbarResponsive" aria-expanded="false" aria-label="Toggle navigation">
<span class="navbar-toggler-icon"></span>
</button>
<div class="collapse navbar-collapse" id="navbarResponsive">
<ul class="navbar-nav ml-auto">
<li class="nav-item dropdown">
<a class="nav-link dropdown-toggle" href="" id="dropdown01" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false">Team</a>
<div class="dropdown-menu" aria-labelledby="dropdown01">
<a class="dropdown-item" href="members.html#">Members</a>
<a class="dropdown-item" href="publications.html#">Publications</a>
<a class="dropdown-item" href="teaching.html#">Teaching</a>
</div>
</li>
<li class="nav-item">
<a class="nav-link" href="web_tools.html#">Web Tools</a>
</li>
<li class="nav-item">
<a class="nav-link" href="research.html#">Research</a>
</li>
<li class="nav-item">
<a class="nav-link" href="infrastructures.html#">Infrastructures</a>
</li>
<li class="nav-item">
<a class="nav-link" href="news.html#">News</a>
</li>
<li class="nav-item">
<a class="nav-link" href="contacts.html#">Contacts</a>
</li>
</ul>
</div>
</div>
</nav>
(2)
<script>
$(function() {
$("#header").load("./header.html");
});
</script>
Here is the JS I put at the end of the html page just before the </body> tag:
<script>
$('.navbar .nav-item .navlink').click(function() {
$('.navbar .nav-item').removeClass('active');
$(this).addClass('active');
})
</script>
And here the active css class I want to set to the active nav-link:
.navbar .nav-item > .nav-link.active {
color:white;
font-weight: 700;
}
Please tell me what I am doing wrong...
UPDATE
I put here the solution I found thanks to a simple snippet (that I adapted to my code) taken from this site which @NmiDev kindly pointed to me.
I add my custom active class to the link in the navbar targeted thanks to href / location parsing:
$("#header").load("./header.html", function(){
$('a[href="' + location.pathname.split("/")[2] + '"]').addClass("active-nav");
});

It's seems that you don't need to override the css active class. White is the default behavior.
