3 Days trying to figure this out :/ so any help is welcomed.
The problem is that you should initialize the side-nav in Javascript code like this
var elem = document.querySelector('.sidenav');
var instance = new M.Sidenav(elem);
// with jquery
$(document).ready(function(){
$('.sidenav').sidenav();
});
now your code will work perfect
var elem = document.querySelector('.sidenav');
var instance = new M.Sidenav(elem);
// Initialize collapsible (uncomment the lines below if you use the dropdown variation)
// var collapsibleElem = document.querySelector('.collapsible');
// var collapsibleInstance = new M.Collapsible(collapsibleElem, options);
// Or with jQuery
$(document).ready(function(){
$('.sidenav').sidenav();
});

On the materialize website, this code is given to initialize Sidenav bar
document.addEventListener('DOMContentLoaded', function() {
var elems = document.querySelectorAll('.sidenav');
var instances = M.Sidenav.init(elems, options);
});
but You modify This code and remove option in var instance and now code look like and you should paste this code in your script tag or your javascript file
document.addEventListener('DOMContentLoaded', function() {
var elems = document.querySelectorAll('.sidenav');
var instances = M.Sidenav.init(elems);
});
Now I explain what is the problem in upper code that given on the materialize website
in code, variable instances give 2 arguments 1st argument is elems and 2nd argument is the option that is not defined in your code so you remove the option argument in this code to solve this problem
Initialization is the most important thing when using materialize.js, for example i want to initialize a carousel.
// Javascript
document.addEventListener('DOMContentLoaded', function() {
var elems = document.querySelectorAll('.carousel');
var instances = M.Carousel.init(elems, options);
});
// Or with jQuery
$(document).ready(function(){
$('.carousel').carousel();
});

I am kinda new to website development, so I am asking for some help on the matter. I have the following snippet of html
<!DOCTYPE html>
<html lang="en">
<head>
<script src="https://code.jquery.com/jquery-1.10.2.js"></script>
<meta charset="UTF-8" />
<meta http-equiv="X-UA-Compatible" content="IE=edge" />
<meta name="viewport" content="width=device-width, initial-scale=1.0" />
<!--CSS Styles -->
<link rel="stylesheet" href="../assets/css/styles.css"/>
</head>
<body>
<!--Navigation bar-->
<div id="nav-placeholder"></div>
<!--end of Navigation bar-->
</body>
<script src="../assets/js/navigation_bar.js" type="text/javascript", locator="about"></script>
</html>
It calls the navigation_bar.js script provided here
locator = document.currentScript.getAttribute('locator');
function changeActiveElement(element_id){
console.log("Called");
nav_element = document.getElementById("navigation");
for (i = 0; i < nav_element.length; i++) {
console.log(nav_element[i].id)
if(nav_element[i].id == element_id) document.getElementById(element_id).className = "active-nav-link";
else document.getElementById(element_id).className = "nav-link";
}
}
$(function()
{$("#nav-placeholder").load("/assets/html/nav.html", function(){
changeActiveElement(locator);
});}
);
whereas the nav.html file is here:
<nav>
<h1>Some name</h1>
<ul id="navigation" class="navigation">
<li><a id="about" href="/pages/about.html" class="nav-link">About</a></li>
<li><a id="compt" href="#compt" class="nav-link">Competences</a></li>
<li><a id="projects" href="#projects" class="nav-link">Projects</a></li>
<li><a id="contact" href="#contact" class="nav-link">Contact</a></li>
</ul>
<button class="burger-menu" id="burger-menu">
<ion-icon class="bars" name="menu-outline"></ion-icon>
</button>
</nav>
The scope of the snippet is to change the class of the a tags listed in the navigation element. The navigation bar is correctly loaded via $("#nav-placeholder").load("/assets/html/nav.html"), yet changeActiveElement function is never executed via the callback.
Can someone explain me this behaviour?
I tested your code and everything is working except that nav_element is not a list and therefore nav_element.length throws an error. You could use document.querySelectorAll("#navigation"); instead, which returns a node list of all selected elements. Although, I would not recommend doing a for loop on elements by id. Use classes to select the elements. Id is only for one element.
This question already has answers here:
Why is simple JavaScript code not running?
(3 answers)
Closed 1 year ago.
I'm trying to get a JS slider to work. I'm using Brackets as my code environment.
I have tried creating a local .js file and putting
<script type="text/javascript" src="https://cdnjs.cloudflare.com/ajax/libs/jquery/2.1.3/jquery.min.js">
<script type="text/javascript" src="my.js"></script>
line in <head>
I have also tried just putting only <script type="text/javascript" src="https://cdnjs.cloudflare.com/ajax/libs/jquery/2.1.3/jquery.min.js"> in <head> and then putting all of the script code within a <script> tag in <head>.
CodePen for that:
https://codepen.io/hiarooo/pen/zYNboJq
As you can see, the slider doesn't function properly.
However, I have noticed that if I simply put the code in the JS box of CodePen (I have commented it, but you can try uncommenting it to see what I mean) then the Slider functions perfectly.
What is wrong with the way I am doing things? I do not understand.
Thank you for any advice.

Try putting this way it works fine,because If you have code in your JavaScript that alters HTML as soon as the JavaScript file loads, there won't actually be any HTML elements available for it to affect DOM yet, so it will seem as though the JavaScript code isn't working, and you may get errors.Thanks :)
I am attempting to set a className to my nav element and it isn't working as intended. When I manually add the class to my HTML it puts a border around the unordered list items and the buttons. When I use js to add it, it shows that the nav tag has the attribute in the inspector but it does not add the border so I do not believe it is working. What am I doing wrong? I have linked to the bootstrap cdn and jquery cdn in the file.

JS
var nav = document.getElementsByTagName("nav");
nav.className = "navbar navbar-default";
console.log(nav);
Instead of using .className = try just setting the attribute of class to whatever you want. The main reason why it's not working, however, is because .getElementsByTagName() returns an array (nodeList) so you need to make sure when you set the class, it's properly indexed.
Using .setAttribute("atr", "value")
var button = document.getElementById("btnGo");
button.onclick = function () {
var nav = document.getElementsByTagName("nav");
for (var i = 0; i < nav.length; i++) {
nav[i].setAttribute("class", "myClassName");
}
};
Using .className
var button = document.getElementById("btnGo");
button.onclick = function () {
var nav = document.getElementsByTagName("nav");
for (var i = 0; i < nav.length; i++) {
nav[i].className = "myClass";
}
};
getElementsByTagName() return an array, you should write document.getElementsByTagName('nav')[0];
This is driving me nuts. I have put the html and javaScript code below. Whenever I refresh my page I get Uncaught TypeError: screen.addEventListener is not a function. I insert any other variable or ID for screen and it works fine.

screen.addEventListener('click', function(){

});
You have a naming issue. It is clashing with the window.screen object
console.log(window.screen);
MDN window.screen
Rename the variable to something else and it works fine.
var screenX = document.getElementById("screen");
screenX.addEventListener("click", function() { alert("x"); });
<div id="screen">Click</div>
or take it out of global scope
(function () {
var screen = document.getElementById("screen");
screen.addEventListener("click", function() { alert("x"); });
}());
<div id="screen">Click</div>
Trying to understand how Javascript and HTML5 work. I have a nav and when you press Part One I'm trying to show Content 1, when you press Part Two..etc. I have tried a couple things, and I am clearly not understand the .next properly, but I can only get it to show the first element, but when I press Part Two, Content Two doesn't show. I guess I am visualizing it wrong, instead of .first(), .next made sense to me since I feel like that would just get the next element. Anyways, here's some code, thanks in advance.

$(document).ready(function () {
$('ul').hide();
$('a.btnDown').click(function () {
$('nav>ul').fadeIn(200);
return false;

//all the content elements
var $suls = $('body>aside>ul');
var $as = $('a.contentDown').click(function () {

$suls.filter(':visible').hide();
//display the content item in the same position as the clicked contentDown
$suls.eq($as.index(this)).fadeIn(200);
}); //closes contentDown

You can use:
$('ul').hide();
$('a.btnDown').click(function () {
$('nav>ul').fadeIn(200);
});
$('a.contentDown').click(function () {
var idx = $(this).index('.contentDown');
$('body>aside>ul:eq(' + idx + ')').fadeIn(200).siblings('ul').hide();
});
