// Title: search-jobs-home.js
// Description: This script is intended for the yacht homepage. It detects wether a certain radio button is checked
// and posts to different url's depending on the selected radio button. It also changes the name attribute of the input box 
// since the internal jobboard accepts "trefwoord" and the external jobboard uses "p_text". Also, the external jobboard does 
// not accept homemade form variables, only a predifined set of attributes. Posting other variables results in a error (400).
