JavaScript JavaScript Basics (Retired) Introducing JavaScript Your First JavaScript Program

Preview opens up a new tab in Chrome, instead of the dialog box. Why?

I've cleared all cache and cookies, and even reset the Chrome settings. Is there another setting that I need to check?

So, it appears as though my dialog box just looks different than McFarland's in the video. But the next thing I'm not getting is that with the first exercise, the "alert" for Thanks for Visiting is popping up before document.write page displays. Sorry for being such a noob; but that's why I'm here.

If I remember correctly I know some videos need be to brought up to date with new JS stuff, document.write will always go up after all alerts are done instead of with them now.

right on. Thanks again. At least I understand what I am seeing, and see the "logic".

put your <src> tag at the very bottom of the page right above the </body> tag so that everything else in the code will run before the javascript

Thanks Dalton. In the first lesson, <src> tag is not even mentioned. But I am moving into the next lesson and I can see that it will be addressed shortly. Thank you for your quick response.

ok. So, I have an alert element on the JS page, that is being referenced by the <src> tag on the HTML page. The <src> tag is at the bottom, above the </body> tag. But, when I preview it, the alert dialog box comes up before the HTML document presents itself.
