I'm following tutorial cideon on JavaScript and wrote some examples in Notepad++ and saved them as something.html. The problem is when I open it with IE or Chrome, the code between <script> and </script> tags doesn't run at all. What is wrong with that?

<!doctype html>
<html>
<head>
 <title>Example of prompt()</title>
 <script>
 var user_name;
 user_name = prompt("What is your name?");
 document.write("welcome to my page ")
 + user_name + "!");
 </script>
</head>
</html>

    Look at the console. You will see an error there... Commented Apr 20, 2016 at 8:44
  • you have a syntax error (closing a parentheses too early) Commented Apr 20, 2016 at 8:44
  • Yeah, Sorry/ I missed that paranthesis. Commented Apr 20, 2016 at 8:47
  • @LPK, where I can find errors on console? Commented Apr 20, 2016 at 8:47

There is a syntax error in document.write statement.

Write it as follow

document.write("welcome to my page "+ user_name + "!");

There is one too many ")"

document.write("welcome to my page " + user_name + "!");

When you open in chrome. Press F12 or Right Click> Inspect Element. Make sure you select "Console" at the top. Pay attention and try to understand what the console tells you.

In your case, this is what it says when I paste that code into my console:

enter image description here

"Unexpected token" This means that it can't understand the script, it was expecting a ; or a new line because you have a bracket at the end. Remove that and it should work.

First, move the script part out of the head to the body tag.

Second, write 

document.write("welcome to my page " + user_name + "!");

in one line and remove the first closing parenthesis.

<!doctype html>
<html>
 <head>
 <title>Example of prompt()</title>
 </head>
 <body>
 <script>
 var user_name;
 user_name = prompt("What is your name?");
 document.write("welcome to my page " + user_name + "!");
 </script>
 </body>
</html>
