The problem with this Captcha is it can be bypassed pretty easily(javascript runs on client, not on server), Suggest making it PHP and using it with AJAX.
Another problem with your Captcha is that you are giving the user the result:
var code = a + b + c + d + e + f + g;
document.getElementById("txtCaptcha").value = code;//why did you put the result available
document.getElementById("txtCaptchaDiv").innerHTML = code;
For example I could just parse the document using an XML parser(getting the info from txtCaptchaDiv), and send the Captcha as input to the txtCaptcha.
I think it would be nice to generate a image, with the result, and add some filters afterwards(on black background images, are hard to recognize).
