JavaScript JavaScript Basics (Retired) Introducing JavaScript The JavaScript Console

JavaScript Basics: The JavaScript Console

(I'm using a Worksource Oregon desktop computer.) I tried to use Windows 7 Professional/Enterprise Internet Explorer 11 on this exercise. I used the F12 key to open the IE 11 console. I highlighted the "Console" tab once the console opened, but I didn't have any code appear in the console box at all to tell me where the errors were in the JavaScript file. I did use the F5 key to refresh the page, but nothing happened. What do I need to do to make the Windows 7 Professional/Enterprise IE 11 console to work properly on this exercise?

I haven't used IE but if the console is blank you might not be getting errors. What I do is normally console.log("Hello World") (in my source code and refresh the page) or something else to make sure that my code is running. Also if you have the opinion I recommend downloading and using chrome because their dev tools are nice and straightforward.

Specifically if you are trying to run loops or conditional statements etc I will console log one thing before the loop and something else inside the loop or condition to see parts of the code are running. Also http://jshint.com/ is a useful tool. Unless you are running an AJAX request for something similar if there are no errors the console is normally blank.

Brigette Eckert: WorkSource Oregon does have Google Chrome, but their desktop computers are set up to run on IE 11 automatically.

I investigated the Microsoft web site & it mentions using the F12 key then Ctrl + 2. See the following links: IE 11 Console: https://msdn.microsoft.com/library/bg182326(v=vs.85), Tools Menu: http://go.microsoft.com/fwlink/p/?LinkID=285857, Console Tool Ctrl + 2: https://msdn.microsoft.com/en-us/library/dn255006(v=vs.85), and IE 11 script errors: http://go.microsoft.com/fwlink/p/?LinkID=285822.

I'm going to try the F12 key & Ctrl + 2 & see what happens. It should work. If it doesn't, I'll have to ask for help again.

I tried both WorkSource Oregon Microsoft Windows 7 Professional/Enterprise IE 11 & Google Chrome JavaScript Console, & neither worked. I suspect the Microsoft Windows 7 Enterprise Mozilla Firefox JavaScript Console won't work at the Multnomah County Library, either.

Team Treehouse, Inc. uses Mac OS X & since their Workspace runs on that system, I don't think it's compatible to Microsoft Windows IE 11, Google Chrome, or Mozilla Firefox JavaScript Console. This is a brick wall to completing this module.

I'm not far enough in JavaScript yet to know how to do loops & conditional statements, nor do I know AJAX, but I'll get there eventually.

I wrote down your web link hint in my notes. Thanks for that.
