Recently I decided to learn Javascript and have been trying to create a script that will put a border around empty elements before the form is submitted. Essentially I want the form to be live validation and notify the user before they click submit. Any help would be greatly appreciated.
There are very many plugins if you want to use jQuery as your title suggests:

Just pick whatever you want :-)
Or if you want to use plain JS, just search "javascript form validation" on google, you'll find thousands of entries, e.g.
http://www.learn-javascript-tutorial.com/javascript-form-validation.cfm and http://www.tizag.com/javascriptT/javascriptform.php

We have an e-commerce site that allows you to check out as a guest.
An individual has been using it to check if stolen credit card numbers function.
We plan to add invisible captcha, which helps for people using scripts/headless browsing/automation, but it doesn't stop someone from manually using it this way.
We could track a cookie that starts to prevent/timeout the user from checking out if there are enough recent requests, but that's easily workaround-able.
It seems like a situation where it can't be limited too much further because normal users need to be able to check out, but are there any other specific methods that would help?

You need to create an array, put it into ng-repeat and push an object into that array onclick of add button.
This must be helpful. http://www.shanidkv.com/blog/angularjs-dynamic-table-addremove-action

I want to build a calendar with javasCript that allow users to enter their shift manually and have 2 option when a date is clicked on( swap or give away)? any thought on how to do it? im I going to need an API? building the calendar will I have to build it using table or which is most efficient way?
I am a rookie coder who started less than a month so pardon if I am not too specific.
How about a php calendar? This works good http://fast-apps.co.uk/fast_cal.php#go
Also you can use Google Calendar and embed that too.
Here is an example of where I have it.

I'm making a php mysqli forum, and i would like users to be able to style their posts so it doesn't look so dull.
I want some basic buttons, like [Header1,Header,Header3,Normal,] and also [italic,bold,underlined]
I now have two questions,
1.
How do I make the buttons and style the textarea?
How do i get styled text into a mysql db?
Thanks in advance.

Use things like TinyMCE, it as all the things you need and manymore. It will make you textarea a full richtext editor.
You can't do it as is without any javascript.
You can use another editor.
To get styled texte from you database, you need to save the text with the formatting before restoring it.

Could someone please point me at a resource that shows how to add buttons to a textarea on a web page? Similar to Yahoo mail where an email address is turned into a button with a cross for removal.
In fact exactly how tags are added to the Tags textarea on this site.
There are very good jQuery plugins that accomplish this. One of them is tag-it library. You can find examples on this page, as well as source code and documentation on how to use it. You can always style it according to your needs through css.
