Java Script not working with Chrome.

I've been working through the Java Script Basics lessons and all was going well until the last 2 lessons. When I hit preview, my code doesn't do anything. I've double and triple checked that I've typed just what the teacher did and I'm pretty sure it's correct. I even tried typing in "document.write ("test"); on the first line and still nothing shows up in the preview. Anyone know what I'm doing wrong?

I would recommend trying to refresh the browser and see if that restores your preview. If not please paste your code here. Often times it's something simple but easily overlooked.

If we could see your code, it would be really helpful. Something as simple as a misplaced semicolon or bracket can cause JS to just not run.

Though first, I would say that you should try refreshing your page. That sometimes does the trick.

Here's the code I have, right off the video. I've tried refreshing and that doesn't work.

var answer = prompt("What programming language is the name of a gem?"); if ( answer === 'Ruby' ) { document.write ("<p>That's right!</p>); }

Again, the prompt screen never shows up. And JavaScript is turned on on my browser.

Megan -

I noticed in the code you posted that you are missing a closing parenthesis in your "That's right!" statement. I'm not sure this is the problem. Can you try the following. Open up the javascript console in chrome. (Usually either shift+command+J pr shift+control+J). At the console prompt type in or paste your first line of code

var answer = prompt("What programming language is the name of a gem?");

Then if the prompt pops up enter Ruby and press return. They type console.log(answer). This should print "Ruby" to the console. See attachment:

If this all works then chrome isn't the issue. Do you have something running which prevents popups?

Just tried and the first line works in the console, the prompt box showed up and everything. Pop-ups aren't blocked, that was one of the first things I looked into.

I tried just putting the first line of code into workspaces and it doesn't work still, even though it works in the console.

There is nothing wrong with the code and chrome seems to be working. I'm assuming you've had workspaces working before. The only thing I can think to try is maybe another browser. Firefox is a good option. If you still can't get it to work I would contact support directly.

Yes, I've been using Workspaces for a couple months with no problems until the last 2 lessons. Thank you for double checking my work, I was thinking it is a technical problem also. I'll contact support.
