alert("hello there"); not rendering

js code: 

alert("hello there");
document.write("No it works!");
console.log("program complete");

html includes: 

<script src='scripts.js'></script>

Why is this not working?

I had the same problem. I would click the preview icon but no alert would display and the console gave the same errors. After clicking the refresh button on the browser (Chrome) it worked as it should. I'm not sure why it was doing that. Maybe it had something to do with the cache.

Hitting the refresh button in Chrome does the trick for me!!!

My guess is that you blocked your site from displaying alerts. Check your browser's settings for how to un-block it

Hey there Cora!

So depending on your browser you should be able to bring up a console. This is a text input area where you can test individual bits of code in real time. (If you're using Google Chrome you'll find it in Developer Tools in More Tools.)

If you were to enter alert("hello there!") into the console, it does in fact throw and alert, so there's no problems there in terms of syntax. If it doesn't, then you'll need to re-enable pop up alerts in your browser window. A quick Google search should give you a detailed how-to.

i fixed the code as the teacher told. Im not having the alerts too.

Im using chrome, and even when i save the changes, the javascript console is giving me the same error.

So i think the problem is not in the browser, the problem is that the changes are not saving......

I am using Chrome as well. I have found that with a lot of these videos, you need to close your workspace and clear your browser data in between every video. Its a pain, but it works.

With Chrome, you should go into your advanced settings and manage exceptions in:

chrome://settings/ *Content Settings *JavaScript -> Manage exceptions -> Create new entry in the list [.]teamtreehouse.com -> Done Plugins -> Manage exceptions -> Create new entry in the list [.]teamtreehouse.com -> Done PopUp -> Manage exceptions -> Create new entry in the list [.]teamtreehouse.com -> Done

I fixed my problem with this steps
