I got a fine email about questions, and in that email it said if I had further questions about the contents of the j query book I should ask in the forums. So I register, expecting to find a forum for this book I got from SitePoint and there IS no such forum. It’s bewildering. The closest thing is the JavaScript forum.
I have this question about the book Jquery Novice To Ninja on page 237 on the last line of code in the example it shows label.text(‘OK!’).addClass yada yada …
The example mentions that this label.text property is styled to show a green checkbox if the validation passes instead of the text ‘OK!’ and the example on the next page shows this.
The question is, if this is showing a green arrow instead of ‘OK!’ then what is the purpose of the string ‘OK!’ in the above line of code? 
Hi GarryFre, welcome to SitePoint! 
The JavaScript forum is the best place for questions about that book, but I understand what you are saying about this being unclear. If there were forums for each book, it’s unlikely that they would be visited often, so the liklihood of getting prompt replies would be less. The JS forum is very active, so you’ll most likely get more reliable answers there, and lots of people there have the book, too.
I’m working through this book also, but I’m not up to that page yet. However, looking at that page, my ‘educated’ answer would be that it’s always good to have some fallback text in case images don’t load, or in case people are using screen readers etc, which rely on text. From an accessibility point of view, it’s never good to have a meaningful image without some meaningful text to accompany it as a fallback.
I suspect that’s the reason.
