I have a fairly simple HTML file:
<!doctype html>
<html>
<head>
<meta charset="UTF-8">
<title>deploy.rb</title>
<script src="test.js" type="text/javascript"></script>
<script src="OtherScript.js" type="text/javascript"></script>
<link rel="stylesheet" href="style.css">
</head>
<body>
body
</body>
</html>
test.js looks like this:
window.onload = function () { alert("It's loaded!") }
Can someone tell me why I don't get an alert when the page loads? (and why none of the functions in OtherScript.js are executing)
The full contents of the html file can be found here, if it helps.
I'm an idiot. OtherScript.js also used window.onload. I consolidated both scripts into the same file, and now it works file.
you might check the directory structure. The code looks fine to me, so if I had to guess the .js files are not being found correctly. If they're in the same directory as the HTML file you might try appending ./ to the beginning of the filename.

so this is my code:
<!DOCTYPE html>
<html>
<head>
<link rel="stylesheet" href="style.css">
</head>
<body>
<script type="module">
import * as THREE from 'https://unpkg.com/three#0.126.1/build/three.module.js'
const scene = new THREE.Scene
console.log(scene)
</script>
</body>
</html>
it works just fine but as soon as i put the "src="script.js" to the script tag, the code suddenly stops working... can somebody explain to me why this is happening?
Each script tag only loads from either src or from within the body, not both. You'll need 2 script tags to load the inline code as well as the script file in one of them each.
I'm trying to work with three.js and really just html and js in general for the first time. I'm playing around with the example code and I found that even if I import the three.js file from the script tag in my Main.js file, it doesn't work unless I uncomment the script tag currently commented out. Why is this the case? Is there anyway i can run it in just my Main.js file without the first script tag?
<!DOCTYPE html>
<html>
<head>
<!-- <meta charset="utf-8"> -->
<title>My first three.js app</title>
<style>
body { margin: 0; }
</style>
</head>
<body>
<!-- <script src="node_modules\three\build\three.js"></script> -->
<script src="js/Main.js"></script>
</body>
</html>
please try this option: in your main html page <script type="module" src="js/Main.js"></script> and in your main.js page import other js pages
Try replacing
<script src="node_module/three/build/three.js"></script>
with
<script type="module" src="node_module/three/build/three.module.js"></script>
If you are importing module functions, it should be declared as a module.
(Not sure why type="module" should be part of the tag
<script src="js/Main.js"></script>
unless Main.js is exporting functions to be used outside of it.)
I'm working on a project, and I didn't understand why a call to external script doesn't work.
Then I just did a extremely simple page html which includes a script alert, as you can see below... Can you tell me what's the problem ? I believe the problem is not the code, but what else can it be?
My browser is a recent Chrome, and my OS is Ubuntu.
My HTML file is index.html :
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<meta http-equiv="X-UA-Compatible" content="IE=edge">
<title>MyPage</title>
</head>
<body>
<p>Blablabla</p>
<script type="text/javascript" src="/script.js"></script>
</body>
</html>
The Javascript file is script.js in the same folder:
<script type="text/javascript">
alert('Hey');
</script>
Paths starting with / are absolute paths. If the script and the HTML page are in the same directory, the script's path is simply "script.js":
<script type="text/javascript" src="script.js"></script>
<!-- Here --------------------------^ -->
If the file is in the same folder remove the "/" from script.js
<script type="text/javascript" src="script.js"></script>
Also if the js file has the script tags remove them.
If you want the alert when the doc is ready, consider doing something like:
document.addEventListener("DOMContentLoaded", function(event) {
alert('Hey')
});
I think that the script in the file dosen't need this script tag
<script type="text/javascript">
alert('Hey');
</script>
you can make like this
alert('hey');
just that try out and check if the file path in html to the js file is the right one.
Hi you don't need the script tags in the file:
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<meta http-equiv="X-UA-Compatible" content="IE=edge">
<title>MyPage</title>
</head>
<body>
<p>Blablabla</p>
<script type="text/javascript" src="/script.js"></script>
</body>
</html>
The Javascript file is script.js in the same folder:
alert('Hey');
I have solve this problem by using Visual Studio. Just open the html file in VS and then run this file from here. It will connect your js file to html.
I have one file, that is external from my index.html page, named code.js with this code on it:
function parse() {
if (a === 1)
alert("a equals 1");
}
(function() {
parse();
})();
As I said, that file is called code.js.
Now, I have an index.html file that is in the same folder/directory as the code.js file. Now, this is my index.html:
<!DOCTYPE html>
<html>
<head>
<title>Javascript</title>
<link rel="stylesheet" type="text/css" href="style.css" />
<script src="code.js"></script>
<script type="text/javascript">
var a = 1;
</script>
</head>
<body>
<h1>Javascript</h1>
</body>
</html>
So I want to be able for the code.js file to use the variable from my javascript that is in the index.html file. I am doing this because I am going to make my own javascript library, but I need to do learn this first. Any solutions?
Switch the order of your script tags:
<script type="text/javascript">
var a = 1;
</script>
<script src="code.js"></script>
This way, the global variable a will be initialized before the parse method in code.js is called.
To add on to what Robby said, browsers load a page in order from top to bottom, left to right, because that is how they are written (sort of). This means in your supplied code, code.js is loaded and run before you set a=1. As Robby mentioned, you can easily switch the order of your <script> tags and be fine.
This applies to other elements as well, so any other elements will not be accessible before their place in the HTML document. For example, a <div> in the body cannot be referenced by code run in the head, because the body has not been loaded yet. You can circumvent this by adding a <script> tag at the end of your HTML document, to be run after the main document has been loaded, but not necessarily all other external data like images (external scripts should be fine, however). The snippet below is what I have found works best:
<!DOCTYPE html>
<html>
<head>
<title>Javascript</title>
<link rel="stylesheet" type="text/css" href="style.css" />
<!-- Any script here could be anywhere (embedded/external) and in any order -->
<script>
function ready() {
document.getElementById('a').textContent = 'a = ' + a;
}
</script>
<script type="text/javascript">
var a = 1;
</script>
<!-- <script src="code.js"></script> - load external code here -->
</head>
<body>
<h1>Javascript</h1>
<div id="a">a = ?</div>
<script>ready(); // Runs code after document is initialized</script>
</body>
</html>
Here´s my html code:
<!DOCTYPE html>
<html>
<head>
<script type="text/javascript" src="/Users/EdvinHedblom/Library/MobileDocuments/com~apple~CloudDocs/javascriptfile.js"></script>
</head>
<body>
The problem is that it doesn't take the functions from path. what am i doing wrong?
Make sure your index.html and js file folder same disk.
2.and just remove / in src at the beginning.
<script type="text/javascript" src="Users/EdvinHedblom/Library/MobileDocuments
/com~apple~CloudDocs/javascriptfile.js">
</script>
or just save your javascript.js file in folder name called "js"
and link your js file this,
<script type="text/javascript" src="js/avascript.js"></script>
First check whether that js file exists in the given path , if so
try to use like this
src="Users/EdvinHedblom/Library/MobileDocuments/com~apple~CloudDocs/javascriptfile.js"
If you load a file from the filesystem, then the prefix file:// should be used.
If an absolute path is used, don't forget the additional slash representing the root of the filesystem (in total three slashes).
In your case the HTML should then look like:
<!DOCTYPE html>
<html>
<head>
<script type="text/javascript" src="file:///Users/EdvinHedblom/Library/MobileDocuments/com~apple~CloudDocs/javascriptfile.js"></script>
</head>
<body>
</body>
</html>
