Add new 'canProgress' event for Introduction Screen

[davoutuk]

Can I suggest adding a new event to this otherwise excellent widget?

Add a new 'canProgress' event that can be used to check whether it is valid to progress to the next page, like:

canProgress: (page) {
// return true if movement to next page is permitted, or false if the progression is to be stopped.
}

Hi, you can already freeze the scroll and/or hide progress dots by using :
freeze: true
isProgress: false

But yes, a canProgress event could be nice.
I will try to add it in next release, but not much time to maintain this project :/

@davoutuk I can add the event but couldn't get exactly what you want. Could you please explain more why do you need such event. Why do you need to check whether it is valid to progress to the next page?

Hello, I was trying to use this widget as the basis for a UI wizard, with text and radio button inputs on each page. For this, I wanted to have a facility to validate the inputs at a page level, and the introduction of a page level 'canProgress' event would allow the validation to be performed inside that event handler.
