I have a very simple MailChimp signup form on my site. It’s a text field, and a submit button. I want this to submit without reloading the page, and to have very simple (ie unformatted) error reporting. No fancy floating message bubbles etc.
There is over a decade of posts on this topic, but there are so many variations and complications to them it's hard to work out what is the current best and simplest method. I’m not a programmer, so it’s been very hard to work out what to use.
Does anyone have a definitive example of code that achieves this? I would have thought that given how popular MailChimp is, they would provide their own embed code that does this, but the one I have generated from their site still reloads the page and has ugly error message formatting I can't change.
