There are many scripting languages used in web design. This is essential in developing a web site for businesses and requires more work if the website is made with a goal to compare parcel delivery prices because coding is more complex.

For the scripting languages, there are many types such as JavaScript, Perl, VBScript, Hypertalk, AppleScript and Lingo. The most popular of these languages is JavaScript which was originally released as LiveScript by Netscape. Once it has converted into JavaScript, the language became more universal making codes compatible with about any type of platform as long as a JavaScript interpreter is installed.

With the rise of applications that are web compatible, scripting languages are also in demand. New scripting languages are developed to accommodate those who have basic knowledge regarding programming. Another factor that impacted the development of scripting languages is the evolving power of today’s computers. This means that the scripting language should also be able to keep up with these modern changes.

There are many advantages to today’s recently developed scripting languages such as ease of use and mastery, even the ones with no or basic knowledge in programming will be able to use it, complex tasks can be accomplished in just a few steps, there are many text editors available and running code is faster as well as editing it.

The main disadvantage with modern scripting languages is it can be easily downloaded by anyone without the maker being aware that their system is already being hacked. This weakness is what makes JavaScript together with VBScript still a more reliable option.

There are many elements in a webpage where scripting languages can be used. If you want to have rollovers on either the text or image, you can do so with scripting language. There are websites wherein popup windows are necessary such as inputting a date from a calendar this can be done by using Java applets or by installing ActiveX controls.

If the user has to fill out a form when they compare parcel delivery prices, you can place asterisk in fields that are required. If nothing is inputted in these fields, the form will not be submitted and an error message will prompt the user.
