Newbie stuck with jQuery alerts not prompting notifications in browsers
Question
I started learning jQuery on thenewboston.com and got stuck after a dozen tutorials. When I was learning JavaScript, I had no problem with alerts and prompts - they would pop up in the browser. I started having problems after I stared learning jQuery.
I have a simple code that should count all the elements on the page and prompt user the number of elements.
For index.html file:
<html>
<head>
</head>
<body>
<p>Some text.</p>
<script type="text/javascript" src="js/jquery.js"></script>
<script type="text/javascript" src="js/selectors.js"></script>
</body>
</html>
For selectors.js file:
var count = $('*').length;
alert(count);
jquery.js is filled with code downloaded from the official jQuery site (compressed production version).
The code you see here is provided by thenewboston.com instructor, and I checked it dozens of times for mistakes (the videos appear a bit older, don't know if something drastically changed in the meantime). Also, file architecture is fine. Both jquery.js and selectors.js are within js folder, and index.html is in root.
What I try so far after googling:
- tried Firefox and Chrome
- tinkered with permission settings in both browsers (turned notifications off and on)
- tried putting the -script- code within the -head- tags
- tried changing
type="text/javascript"totype="application/javascript"within -script- tags
Sorry, I changed <> symbols with -- because I had some formatting issues within bulleted lists.
I tried researching, but I couldn't find a solution to this problem. I found something similar (I think on stackoverflow even), and the OP managed to find a solution by turning his browser notifications on.

This code works just fine .
var count = $('*').length;
alert(count);
You can even run it in the dev console, and it works.

Okay, nvm guys I found a solution...
I was using Firefox when I was downloading jQuery. What happened was that Firefox opened a new tab with all the code after clicking download. I copy-pasted that code to my empty text file and called it jQuery.js.
Now using Chrome, I downloaded it again, and it was the real deal. I just renamed it, and put it in the js folder, and voila. feeling stupid
Thx for the answers and effort guys!
