As the upcoming Zend Framework is going to implement AJAX functionality I really hope that they will integrate the prototype.js library. I realise that this is also used by Ruby on Rails which Zend is trying to avoid giving the impression they are ripping off. However it is a fantastic library and it would be great to see it become almost a standard. It can be relied on as it is being actively developed and is involved in major frameworks at this stage. In addition there are number of JS scripts and projects already implementing prototype.js. So … here's hoping!
