JavaScript page is blank (empty white). What should I do?

@JMRKERJun 08.2016 — #I am new at JavaScript.

I tried different web browsers (Chrome and IE). I tried different JavaScript code (e.g., to check the version of JQuery or to print "Hello World" in an alert box) that I got off the Internet. Nothing works. I use tags like this:

<html>
  <body>
  <script>

I use closing tags like these:

</script>
  </body>
  </html>

I tried .js extensions of different files of JavaScript code with the tags above. But these didn't work. The .jsp extensions render completely white pages with no content. How do I get the content of JavaScript to render and display properly?[/QUOTE]

What does the rest of your code look like?

What you have posted will only display a blank page (as expected).

@ZorgJun 08.2016 — #FYI:

[B]JavaScript[/B] is commonly used as a client side programming language with a file extension of [B].js[/B] (this code runs on the browser) and [B].jsp[/B] is a server side programming language for [B]JavaServer Pages[/B] (this runs on the server). The names are similar but these are not the same programming language.

If your trying to run the code above with the [I]<html>your code</html>[/I] tags then the file must have an extension of .html, not .js - HTML files commonly contain JavaScript and CSS.

[B]Example:[/B]

Copy this and name your file index.html - open it in the browser.

[code=html]
 <!DOCTYPE html>
 <html>
 
 <!-- anything in this head tag runs first -->
 <head>
 <title>JavaScript Use</title>
 <!-- put javascipt with in the head element -->
 <script>
 alert('Hello World'); // this will create a popup alert that says Hello World before the page loads completely
 </script>
 </head>
 
 <!-- anything in this body tag runs next -->
 <body>
 
 <h1>JavaScript Use</h1>
 <p>The button below also uses JavaScript when you click on it.</p>
 
 <button type="button"
 onclick="document.getElementById('hello').innerHTML = 'Hello Again!'">
 Click me for a nice greeting.</button>
 
 <p id="hello">This text will disappear...</p>
 
 <!-- if you put javascipt before the closing body tag, it will run after everything above loads-->
 <script>
 document.getElementById('hello').innerHTML = 'TADAAAAH!'; // This text will be in the <p id="hello"></p> after the page loads.
 </script>
 
 </body>
 </html>
 [/code]
