Javascript
JavaScript is a programming language (not to be confused with Java) and can be used to add functionality to a website that cannot be achieved by using just HTML and CSS. For example data validation, image swapping and multi-level menus are functions that can be written using JavaScript.
The scripts (list of programmed instructions) can be stored within the HTML code itself, but the better approach is to have a separate JS function which is ‘called’ from the HTML. Storing the JavaScript as a separate function not only increases website maintainability it makes testing less onerous.
But although JavaScript can be used to add additional functionality to a website it is also important that the website works without JavaScript. For example some users disable or switch off JavaScript and some older browsers do not support JavaScript.
Web Marketing (Part Two)
Part one of this series highlighted the importance of having a good website.
Equally important for small business is to have a consistent image. This does not mean spending two million pounds with a design consultancy. But having a decent logo design, clear strapline (see below) and message etc embodied in the website, business cards and stationary builds credibility and looks more professional … and need not be expensive.
A strapline is the short phrase that best describes your business. This could be your USP – unique selling point eg "24-hour mobile chiropractor - there to get you mobile."
And having a professionally printed postcard advertisement in your local library or shop should be complemented by a website in the same style, with the same message. This attention to detail shows that you take your business, and therefore your clients, seriously.
