Introduction to Programming – my first program

Hello. I am a beginner and I would like you to help me. While studying the video Programming > Introduction to Programming > Basics > Writing Your Program I found some problems in the result of my exercise. This is what I did:

First I tried to repeat the exercise that the teacher, Jim, wrote in the video, that's to say I wrote the file index.html, then myScript.js, both in the same directory. Here are the codes:

-------- index. html ------------------------------
<! DOCTYPE html>
<html lang="en">
   <head>
     <meta charset="utf-8">
     <meta name="keywords" content="">
     <title> Introduction to Programming </title>
     <script src="myscript.js"> </script>
   </head>
   <body>
   <h1> Introduction to Programming </h1>
   With <h2> JavaScript </h2>
   </body>
</html>

-------- myscript.js ------------------------------

console.log ("Hello from MyScript.js");

I opened the index.html file with the Chrome browser and also I opened "Developers tools" to look for the expected result (the message "Hello from myscrpt.js)… But I got this message:

 x   Failed to load resource

What is the problem? Is it related to local web server? I noticed that Jim uses localhost in the browser, but I do not know what I can do to install a local server to work with Chrome. What to choose? Is there a guide to do it? I'm lost.

thanks for help in advance. Eva

I finally found the answer! My two files were well written. I installed XAMPP on my computer. I stored my two files in htdocs \ MyProjects\ ... and the script worked: I coul read the message "Hello from MyScript.js"

When programming you need to remember the computer does EXACTLY and ONLY what you tell it to do.

I think this should be fixed if you remove the erroneous spaces in your code.

IE: 
</ head> 
should be 
 </head> 
with NO space in it.

Fixed Code:

<! DOCTYPE html>
<html lang="en">
<head>
 <meta charset="utf-8">
 <meta name="keywords" content="">
 <title> Introduction to Programming </title>
 <script src="myscript.js"> </script>
 </head>
 <body>
 <h1> Introduction to Programming </h1>
  With <h2> JavaScript </h2>
  </body>

</html>

Thanks Seth. I wrote </head> without spaces in my index.html. The program doesn't work.

Eva,

I'm not sure what the source of your problem is... I copied and pasted your HTML and JavaScript into separate files, and (after removing the whitespace as SETH suggested) I was able to view the console.log() output in Chrome. Are you sure that your index.html and myscript.js files are located in the same directory?

Best,

– J.

Hi J.

Both files are in the same directory (D:\sites\t4\index.html and D:\sites\t4\myscript.js) No spaces within tags. I don't have localhost

Thank you
