I am trying to use particle-js for my website. My code is quite simple, since it is the very first thing I tried to implement.
My project consists of 4 files: code.html, particles-config.json, particles.js and style.css. With the last one still being empty.
The code.html file:
<!DOCTYPE html>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
<title>My Website</title>
<link rel="stylesheet" type="text/css" href="style.css">
<script src="https://code.jquery.com/jquery-3.6.0.min.js"></script>
<script src="particles.js"></script>
</head>
<body>
<header>
<p>Test 1</p>
<div id="particle-div"></div>
<button id="particle-button">Start</button>
<p>Test 2</p>
<script>
$("#particle-button").click(function(){
particlesJS.load('particle-div', 'particles-config.json')
});
</script>
</header>
</body>
</html>
And the config file is just with the content from the one provided on this github under particle.json. And the particle.js is the exact same file from the github.
However when I run the code, I dont see the particles. It just opens up an empty white space between Test 1 and test2. I amlso not getting any error messages in the browser console (I use Firefox).
Could anyone tell me what am I doing wrong?
EDIT:
Here is a screen shot of the network tab:

I have been looking for a way to get the same navigation bar on every page. Right now, I have a jQuery script that is loaded onto every page, that should replace a div placeholder; however, when I run the program, the navigation bar is simply not there.
JQuery code:
$(function() {
$("#dropdown").hover(function() {
$("#submenu").stop();
$("#submenu").slideToggle(500);
});
$("#submenu").hover(function()
{
$("#submenu").stop();
$("#submenu").slideToggle(500);
});
$.get("navigation.html", function(data){
$("#nav-placeholder").replaceWith(data);
});
});
Navigation file:
<nav>
CV Game Development
<div class="menu">
<div id="dropdown">Tutorials</div>
<div id="submenu">
Beginner
Intermediate
Advanced
</div>
</div>
</div>
</nav>
Actual HTML file to be used:
<html>
<meta charset="utf-8">
<meta name="viewport" content="width=device-width">
<link rel="stylesheet" type="text/css" href="main.css">
<script src="https://code.jquery.com/jquery-3.1.1.js"></script>
<script src="main.js"></script>
<head>
<title>CV Game Development</title>
<div id = "nav-placeholder"></div>
</head>
<body>
<h1 id = "intro">Welcome</h1>
<h3 id = "subintro">to the CV Game Development website</h3>
<p id = "info">Here is an abundance of information to get you started making 2D games with GameMaker: Studio.</p>
</body>
</html>
It seems like it should work, and yet, it doesn't. Any help is much appreciated, thank you!
As Mohamed-Yousef noticed in comments you have placed your nav-placeholder div element in head tag, which is wrong place for it.
It should be inside body element.
Also your meta, css and script tags must be in head element.
<html>
<head>
<title>CV Game Development</title>
<meta charset="utf-8">
<meta name="viewport" content="width=device-width">
<link rel="stylesheet" type="text/css" href="main.css">
<script src="https://code.jquery.com/jquery-3.1.1.js"></script>
<script src="main.js"></script>
</head>
<body>
<div id="nav-placeholder"></div>
<h1 id="intro">Welcome</h1>
<h3 id="subintro">to the CV Game Development website</h3>
<p id="info">Here is an abundance of information to get you started making 2D games with GameMaker: Studio.</p>
</body>
</html>
1st: give <nav> an id to be
<nav id="nav">
2nd: you can use .load() instead of .get() .. And the.load() code should looks like
$('#nav-placeholder').load("navigation.html #nav");
The above code will wrap <nav id="nav"> into <div id="nav-placeholder">
3rd: if you need to replace with you can use unwrap() instead .. so your code should be like this
$('#nav-placeholder').load("navigation.html #nav" , function(){
$('#nav').unwrap();
});
4th: I don't know yet Why your <div id = "nav-placeholder"></div> inside <head> but any way I tested it and the code will work even if its wrapped to <head> ..
<!DOCTYPE html>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
<script type="text/javascript" src="../scripts/angular.min.js"></script>
<script type="text/javascript" src="../scripts/jquery-3.2.0.js"></script>
<link rel="stylesheet" type="text/css" href="../css/home.css">
<title>Hello</title>
</head>
<body>
<div id="d1">

</div>
</body>
</html>
I am trying to add styles to html elements in jsp page but when i add the style and run it on tomacat 9.0 nothing happens there and only plain text appears.
And when I moved to page source and click the links to css it shows me an error
HTTP Status 404 – Not Found
Type Status Report
Message /TutorNextDoor/css/home.css
Description The origin server did not find a current representation for the target resource or is not willing to disclose that one exists.

You can move your css and scripts folder inside Webcontent and give the path in the html/jsp file in the following manner :
<!DOCTYPE html>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
<!-- Scripts -->
<script type="text/javascript" src="<%=request.getContextPath()%>/scripts/angular.min.js"></script>
<script type="text/javascript" src="<%=request.getContextPath()%>/scripts/jquery-3.2.0.js"></script>
<!-- CSS -->
<link rel="stylesheet" type="text/css" href="<%=request.getContextPath()%>/css/home.css">
<title>Hello</title>
</head>
<body>
<div id="d1">
asfsdg
</div>
</body>
</html>
I'm just starting on JavaScript and I'm following along this online course where it claims that if I insert <script> tags at the bottom of the page just before the <body> closing tag I should be able to see the website render first followed by the JavaScript code, but it is actually executing the other way around, the JavaScript code executes first and it's not until after I click "OK" on the message popping up that I'm able to see the website fully rendered.
Here is the code
index.html
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8">
<link rel="stylesheet" href="css/main.css">
<title>JavaScript Basics</title>
</head>
<body>
<div class="container">
<h1>Where to place your JavaScript code.</h1>
</div>
<script src="scripts.js"></script>
</body>
</html>
scripts.js
alert("This text should appear after page is fully rendered");
I honestly don't know if this is how the code is supposed to work. Do alert(); scripts always execute first? Maybe the browser has something to do with it? (I'm using the latest version of Chrome). Anyhow, a well explained answer of what's happening would be much appreciated.
Personally, I would do something more like:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8">
<link rel="stylesheet" href="css/main.css">
<title>JavaScript Basics</title>
</head>
<body>
<div class="container">
<h1>Where to place your JavaScript code.</h1>
</div>
<script>
window.onload = function() {
alert('This should now load after the page.');
}
</script>
</body>
</html>
The window.onload = fun... says "wait until the page has finished loading". Depending on what the browsers decide to (with images, layout, plugins etc.), this may or may not work for you.
Or even something like:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8">
<link rel="stylesheet" href="css/main.css">
<title>JavaScript Basics</title>
</head>
<body>
<div class="container">
<h1>Where to place your JavaScript code.</h1>
</div>
<script async defer src="scripts.js"></script>
</body>
</html>
With this example, the async attribute means "grab this script file in the background" and the defer means "wait until the page has loaded to execute it".
I'm not really sure why this is not working but I have an MVC View that I want to display the current date/time/seconds on the page. I've put the javascript in the "Scripts/script.js" file. I then added the following at the bottom of the MVC View.
#section scripts {
<script src="~/Scripts/script.js"></script>
<script type="text/javascript">
$(document).ready(function () {
setDateTimer();
});
</script>
}
Thing is when I run it something is causing an error. Unfortunately at the moment I can't see the actual error message because of the way they have the site configured any error just takes you to a generic error page. I do know it has something to do with the code above because removing it cause the page to work.
For testing purposes I even removed all but simple javascript code in the file but that still doesn't work. Right now this is all that is in my script.js file.
function setDateTimer() {
var today = new Date();
}
I know the name of the of the .js file in the code is correct because I just dragged and dropped it to the page from the solution explorer.
Here is most of my _Layout page.
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8" />
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<link href="~/Content/Site.css" rel="stylesheet" />
</head>
<body>
<div class="container body-content">
#RenderBody()
<footer></footer>
</div>
<script src="~/Scripts/jquery-1.10.2.min.js"></script>
<script src="~/Scripts/bootstrap.min.js"></script>
<script src="~/Scripts/modernizr-2.6.2.js"></script>
</body>
</html>
Layout page doesn't have a place to render the section you can change it like
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8" />
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<link href="~/Content/Site.css" rel="stylesheet" />
</head>
<body>
<div class="container body-content">
#RenderBody()
<footer></footer>
</div>
<script src="~/Scripts/jquery-1.10.2.min.js"></script>
<script src="~/Scripts/bootstrap.min.js"></script>
<script src="~/Scripts/modernizr-2.6.2.js"></script>
#RenderSection("scripts",true)
</body>
</html>
Context
I've used Mocha before many times, both in the browser and just using the command line. I tend to use Chai's expect module for bdd.
I have five test files that have been working with command line npm test. I just want to run the tests in the browser for better debugging.
Problem
The setup is just boggling my mind. I either get a blank Mocha page without tests or I see the first test flash on screen, then it redirects.
Current specRunner.html
<!DOCTYPE HTML
<html>
<head>
<title>Mocha Tests</title>
<link rel="stylesheet" href="node_modules/mocha/mocha.css" />
<script src="node_modules/jquery/dist/jquery.min.js"></script>
<script src="node_modules/mocha/mocha.js"></script>
<script src="node_modules/chai/chai.js"></script>
<script>mocha.setup('bdd');</script>
<script src="mineLocation.js"></script>
<script src="test/mineTests.js"></script>
<script>
window.expect = chai.expect;
mocha.run();
</script>
</head>
<body>
<div id="mocha"></div>
</body>
</html>
Previous Attempts
I've tried moving script tags around, thinking that dependencies are being unmet at load time.
I've tried relative vs. absolute paths. Console says all the tags are loading correctly.
I've tried modifying the run script tag. When it is as the example above, it turns out a blank page and says "Cannot read property 'appendChild' of null", pointing back to Mocha:
When the run script tag looks like this:
$(function() {
window.mochaPhantomJS ? mochaPhantomJS.run() : mocha.run();
});
It redirects from /specRunner.html to /2,1 and the console error repeats about every 30 seconds.
Here you go, just tested it.
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Mocha Test</title>
<link rel="stylesheet" type="text/css" href="node_modules/mocha/mocha.css">
</head>
<body>
<div id='mocha'></div>
<div id='app'></div>
<script src="node_modules/mocha/mocha.js"></script>
<script src="node_modules/chai/chai.js"></script>
<script src="app.js"></script>
<script>
mocha.setup('bdd');
var expect = chai.expect;
</script>
<!-- Tests -->
<script src="app_test.js"></script>
<script>
mocha.run();
</script>
</body>
</html>
So, I've found that it's not necessarily an issue with the HTML setup, but rather an issue with a test.
Setting the location variable globally within the file causes the strange redirection (to /2,1) and error "Cannot read property 'appendChild' of null".
Moving the variable within the describe statement, on line 4, fixes the problem.
My final HTML is cleaner as well:
<html>
<head>
<meta charset="utf-8">
<title>Mocha Tests</title>
<link rel="stylesheet" href="node_modules/mocha/mocha.css" />
</head>
<body>
<div id="mocha"></div>
<script src="node_modules/mocha/mocha.js"></script>
<script>mocha.setup('bdd');</script>
<script src="node_modules/chai/chai.js"></script>
<script>var expect = chai.expect;</script>
<!-- src files -->
<script src="narcissistic.js"></script>
<script src="morseCodeDecoder.js"></script>
<script src="windComponents.js"></script>
<script src="mineLocation.js"></script>
<!-- test files -->
<script src="test/narcissisticTests.js"></script>
<script src="test/morseTests.js"></script>
<script src="test/windTests.js"></script>
<script src="test/mineTests.js"></script>
<script>mocha.run();</script>
