I am at the start of learning Javascript, but within the first 10min I hit on a Chrome issue. I'm attempting to display the code I wrote with Visual Studio in the Chrome console, but rather than showing the code in the section below the menus 'Element', 'Console', 'Source' etc, the code displays exactly as I wrote it, but in the view panel including all html tags below the menu section 'Apps', 'Bookmarks', 'Customize Links' etc. How do I resolve this, any answers? I tried to use ctrl-o to open the .js file whilst in Visual Studio and also whilst on Chrome, but only the file path to the .js file opened, and when subsequently clicking on the file it looked like the image below.

To clarify - you are loading a .js file in the browser which is what is displaying in chrome (the content of that file).

What you want to do is run that js file and have Chrome's JavaScript interpreter (V8) parse that information. To do that, you must add your script to an index.html page and then in index.html, load that e.g something like <script type="text/javascript" src="script.js"></script>

Alternatively, you can just run the JavaScript directly in index.html via <script type="text/javascript"> // your JavaScript </script>

<html lang="en">
  <head>
    <meta charset="utf-8" />
    <script src="main.js"></script>

Comments
  • Navigating directly to a .js file in a browser will not execute it; it will just show the raw text for you to view. If you want to run it in a browser, create a simple HTML page with a <script> tag.
  • Please don't post pictures of your code, post the actual text of the code.
  • @ScottMarcus In this case I'd argue the screenshot is better. The issue doesn't relate to the code or debugging it, but rather software and/or environment behavior.
  • @TylerRoper A screenshot of what the browser is displaying, yes. But, not of the code, which is what my comment was mentioning.
  • @JavierBrea script.js is a valid javascript, and if there is a global variable script then it would not even throw an error.
  • Thank you @t.niese, yes, to be strict, and suposing you have a global script variable, it would be valid. I was referring to this example, in which no global variable was set, and the intention of script.js was to load the script, not to execute it, and it was wrong. I supose I could explain it better.
  • @JavierBrea not valid javascript means that it has a syntax error. But the given code is syntactically correct and may or may not throw a runtime error, but it is still valid code.
  • Thank you Javier
  • Thank you @Ritu as soon as I read your explanation I understood my error.
