Cross Browser API form Submit

Seeking a small javascript form that will have categories (flooring, painting, windows, lighting etc) I have all categories and category id's. The form will also have a text input area for a zip code. This form will be on my website and submit the data to an API located on another page of my website. The data will have to be captured by this 3rd party API and then populate the search results on that page. My affiliate advertiser has already provided me with the script for their search form and results API. Please inquire if you have any questions.
