The preview doesn't work on my browser until I refresh the tab and then only the first alert displays.

Hey Martin,

I just ran through this exercise following along with Dave's instructions. Try checking your code against this:

alert("Hello from Treehouse");
document.write("<h1>Welcome to JavaScript Basics</h1>");
alert("Thanks for visiting.");

Make sure you're not missing a semi-colon or a closing set of quotations. If it all looks good, try posting your code so we can look under the hood for you.

Also, if you're wondering how to post your code into the forums, follow this:

How to Post Code on the Forums

There are two ways to share your code on the forums here, excluding using external tools from outside of Treehouse.

Method One

The first method is to use a series of three ` (backticks, located at the top left of the keyboard) without any spaces on one line, paste all of your code starting on the second line, then closing the code block with a second series of three backticks. Take a peek at the link for the "Markdown Cheatsheet" located above the "Post Answer" button anytime you're about to post a comment or answer. Using this method, the code will look like this, if you replace the apostrophes with backticks:

'''css
(code here)
'''

Method 2

The second method is a little more convoluted, but it lets us look at your entire project and make our own copy to try fixing issues. I'll order the steps since it can be a little confusing the first time around:

1. Open the workspace you're having trouble with.

2. On the menu bar located to the left of the "Preview Workspace" button is the "Snapshot Workspace" (camera icon), click that.

3. A popout will appear with another button that says "Take Snapshot", click that.

4. It should create a new snapshot, which will appear beneath the "Take Snapshot" button in the popout. Click the snapshot you want to share.

5. The snapshot should open a new browser tab. Highlight the url in the snapshot's browser tab (it should look like this: https://w.trhou.se/ducj79b1i0 ).

6. Create your forum post and paste the snapshot's url into the post. Other Treehouse users will be able to open the snapshot, then 'fork' a new copy to check out.

Keep in mind that you can only ever have five snapshots, but you can delete them by hovering over the snapshot located below the "Take Snapshot" button in the popout and click the trash bin icon.

Good luck!

Not being able to see your code, it's hard to say exactly. But I'd check the browser settings just to make sure you're not somehow inadvertently blocking pop-ups. Keep in mind that the alert counts as just that.

Hey Mathew,

Switch the apostrophes with backticks, I use apostrophes in the example above because it will trigger the code block otherwise.

As for the actual problem, I understand now. If you view a javascript file that isn't linked to anything in Chrome, it will just output the lines within the file as typed. Try linking the script to a barebones index.html file and it will work as intended.

Good luck!

I'm having similar challenges as the initial poster. I'm using textwrangler as my editor - and have saved the file as playaround.js (if that matters). Using a chrome browser, and the text shows up - exactly how it is presented to the browser:

'''js alert("Hello from Treehouse"); document.write("<h1>Welcome to JavaScript Basics</h1>"); alert("Thanks for visiting.");'''

No, sorry that my post was not formatted clearly; I attempted to show that it was javascript. It is written as shown:

''' alert("Hello from Treehouse"); document.write("Welcome to JavaScript Basics"); alert("Thanks for visiting."); '''

right now, I'm viewing this document as a single js document, not linked to anything at all. Could this be a reason why the interactivity is not working when viewed through chrome? Or should it work regardless of being a single js document?

And when I mean "a single js document", I mean that it is not linked to an index.html file like the example shown in Daves tutorial. Any help is appreciated - I am a budding developer with a long ways to go!

I'll use those tips going forward with any issues.

The rest of the coding examples have been going fine.

It may just be my getting used to this platform.

Thanks for the help.

I had same issue. It most likely isn't your code. You have to refresh the browser because the page is cached. So refreshing your browser refreshes the cache.

I hate to tell on myself for something so silly, but I figured out that my alerts were not showing up at first because I didn't save my file before hitting preview. A quick command + s, and my alert showed up immediately. Excuse: This is my first time using the workspace. Like I said, I feel pretty ridiculous, but that might help someone.
