Javascript example

Javascript is an embedded scripting language which works within the Internet Explorer and Netscape web browsers. It has fairly wide acceptance now across all web browser platforms.

I write a lot of Javascript in connection with my work. I have written extensive ecommerce applications using this language. Many of my scripts are distributed free and can be found at Internet.com .

Javascript has the potential to be used for Amateur Radio purposes. This simple example uses the math() function to calculate the length of a half wave dipole for any given frequency. View the source of this page to see how it works. The most difficult bit is getting the results rounded to two decimal places. Its not rocket science but it might encourage you to explore the use of Javascript.

Frequency MHz
Halfwave m ft
Quarterwave m ft
