As marketers we are always building and tweaking lead capture forms. Refining which and how much information to capture based on our percieved value of what we offer in return (whitepapers, free trials, etc.). Building lead capture forms in HTML is not particularly difficult, but unfortunatley HTML provides no standardized way to validate form fields (at least not until everyone is on HTML5 compliant browsers). Therefore, to enforce required fields on forms we must resort to JavaScript. Typically this requires the assistance of a JavaScript developer who must be re-engaged each time the form fields are tweaked. Not anymore.
