Executing a CGI script via javascript

Question

How can I make a cgi script be executed when a javascript function is called? Currently I am using a small iframe and loading the cgi script there, but it does not seem to be working. here is a snippet of code:

function back()
{
    document.getElementById("hidden").src="scripts/backImage.cgi";//execute background script
    document.getElementById("scan").src="scripts/getImage.cgi";//reload the display iframe
}

Answer 1

You can use XMLHttpRequest to trigger access to your cgi script.

Answer 2

You can use jQuery.ajax, or the shorthand:

jQuery.get("scripts/backImage.cgi");
