Javascript is a programming or scripting language primarily used for client-sided programming in web browsers. It can also be used as a server-side programming language but this is generally used less often. Javascript was originally created by Netscape for their browser Netscape Navigator, and is now an implementation of the ECMAScript standard. It is typically used in web browsers for form validation, floating navigation, AJAX and other nifty things to make web pages more interactive.
jQuery has a .data() method for storing data in the DOM should you need to for one reason or other. This is preferable to storing data in some other attribute such as "rel" or "alt" which is often seen in tutorials and examples on blogs.
There are two ways to get substrings using Javascript using the string object's substr() and substring() functions. You could also extract a string using a regular expression but I'll cover that in another post.

A couple of days ago I looked at how to count the words in a textarea or input with jQuery and in this post look at how to do the same but for an FCKeditor instance. FCKeditor is an in-browser HTML editor. The code for counting the words uses regular Javascript and does not require jQuery.
This post shows how to get a word count from an HTML textarea or text input using jQuery and display it on the page. The word count is updated as the user types.
There are a variety of ways to access elements with jQuery including by the name property of form elements (the name="" part of <input name="foo">). This can be useful so you don’t have to assign an id to each and every form element as well as a name which is needed to pass the form value to the next page.
