Talk:Greasemonkey Hacks/Web Forms
Many, if not all, of the descriptions of how to hook submissions from forms are wrong. The following code, simply does not work in FF 3.x:
real_submit = HTMLFormElement.prototype.submit;
HTMLFormElement.prototype.submit = handleSubmit;
window.addEventListener('submit', handleSubmit, true);
It fails with an error in regards to the "prototype" property.
Is there a known fix for this?
