I just wonder what I am doing with console.log is wrong or not.
I have simple two files as below:
index.html
index.js
and when opening the index.html in chrome(c:\temp\index.html), it does not output console.log message in console tab as below.
So am I missing something?
As you can see, if you run it below code, it shows console.log properly.
function doSomething() {
console.log("Work!");
}
doSomething();

Looks like you have a typo:
<script scr='index.js'>
should be
<script src='index.js'>
function doSomething() {
console.log("Work!");
}
doSomething();
<div>Hi</div>
<script src='index.js'> </script>
You have to change scr to src in that way it will works.

I want to use EditorJS in my project. So I have created an HTML file after reading the documentation. Here is the file called index.html:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta http-equiv="X-UA-Compatible" content="IE=edge">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Home</title>
</head>
<body>
<div id="editorjs"></div>
<script src="https://cdn.jsdelivr.net/npm/#editorjs/editorjs#latest"></script>
<script>
import EditorJS from '#editorjs/editorjs'
const editor = new EditorJS('editorjs')
</script>
</body>
</html>
After opening the file into the browser, EditorJS is not showing up and this message is printed in the console- Uncaught SyntaxError: Cannot use import statement outside a module.
How to fix this problem?

<script>
const editor = new EditorJS({
autofocus: true
});
</script>
</body>
</html>
When you add a script tag in your HTML file, you don't need to import the library again you can just start using it!
The script isn't a type module, use:
<script type="module">
hay if anybody understand why is prompt showing up even before the console printing
i appreciate the help
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">

console.log('i should appear first on the console')
var promptInput = prompt('I\'m am here befor anything else')
</script>
</body>
</html>
console.logs are actually asynchronous in that they are synchronized (as in always in order) but perform an asynchronous call.
prompt is a very old API and one of the few that actually blocks the page - so even-though it appears after the console.log you see it as soon as it is called.
That said - this is not true for every console nor is it guaranteed - the console.log may appear before the prompt depending on the browser/console implementation.
If you want to get the console before prompt you can add setTimeOut-setTimeout() is an asynchronous function.

setTimeout(() => {var promptInput = prompt('I\'m am here befor anything else')

i wrote this simple function to show a message when you close the window but it didnt work.
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Document</title>
</head>
<body onunload="closing()">
<script language="javascript">
function closing(){
alert('Bye');
}
</script>
</body>
</html>
Your popup blocker might block it. MDN docs source
That sort of behavior - alerts popping up on a close, are usually not desired by users.
Did you try using the unload event?
The errors appear at the console after i open this code on live server on vscode, im learning Vue.js and the code itself opens the file but i dont know how to fix those errors.
Ive reasearched somethings about the errors but couldnt fix them.`

JavaScript not working on external file
(4 answers)
Closed 5 years ago.
i have 2 files....one html and one js....
html code:
<!DOCTYPE html
<html lang="en">
<head>
<meta charset="utf-8">
<meta http-equiv="X-UA-Compatible" content="IE=edge">
<meta name="viewport" content="width=device-width, initial-scale=1">
<script type="text/javascript" src="external.js"></script>
<title> Sign In And Registration Page </title>
</head>
<body>
<div id="headerTag">
</div>
///codes here....
</body>
</html>
js code:
some functions here performed on click operation.....
function onClickOperation ()
{
///here codes..
}
problem is that the functions are not being called...when i put the same js code in the html file directly, it works....what do i have to do to load those functions from separate js file?
external.js should have the code called after DOM has finished loading like so
document.addEventListener('DOMContentLoaded',function(){
// code here
});
or it should be included inside the body tag below the DOM elements it should interact with
Try wrapping the script in the body and just before the </body> tag:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8">
<meta http-equiv="X-UA-Compatible" content="IE=edge">
<meta name="viewport" content="width=device-width, initial-scale=1">
<title> Sign In And Registration Page </title>
</head>
<body>
<div id="headerTag">
</div>
///codes here....
<script type="text/javascript" src="external.js"></script>
</body>
</html>
