<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?

So...As you can see here, Whenever i live reload this on my browser(firefox, chrome) It just keeps on reloading and dosen't open but when i use the for loop and then use the if condition to skip a loop, It opens.
Please is there something i'm doing wrong, Because i just started learning javascript.
It's because you're creating an infinite loop. When you have the if statement and the continue keyword, it will skip to the next loop without incrementing w variable.
hay if anybody understand why is prompt showing up even before the console printing

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.

Whenever I try to exit the Fullscreen in the console it shows that exitFullscreen is not a function
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1">
<title></title>
</head>
<body>
<button onclick="o()">O</button>
<button onclick="x()">X</button>
<script type="text/javascript" charset="utf-8">
function o(){
document.documentElement.requestFullscreen();
}
function x(){
document.documentElement.exitFullscreen();
}
</script>
</body>
</html>
From the code above by clicking on button x I should exit Fullscreen but it is not happening
Look at the documentation.
requestFullscreen is a method on elements
exitFullscreen is a method on the document
use this for exit the full screen
document.exitFullscreen();
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();

<div>Hi</div>
<script scr='index.js'> </script>

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 need to create a simple mailto function so when I click on the html file it brings up my default email application with the composed mail "ready-to-go." I figured a click event on the mailto ID would be sufficient, but it is not firing. What should I do? FYI, I do not want the user to click on the hyperlink. I plan on removing it.
<script type="text/javascript">
$(document).ready(function(){
$("#mymailto").click();
}); // document.ready
</script>
