Callbacks

[joaqib]

Hi tsuyoshiwada,

First of all thanks for the project because it seems amazing.
The problem I am encountering is that I am not able to create callbacks functions for the scroll.
The example option is in typescript but even if I change it to Plain JS and pass the object as the options, it does not work for me.

I just convert this code into JS and the console.log does not execute before the scrolls

`const scroller = new SweetScroll({

// Stop scrolling case of trigger element that contains the is-disabled class.
before: (offset: Offset, $trigger: Element | null, scroller: SweetScroll): boolean | void => {
console.log('Before!!', offset, scroller);
if ($trigger && $trigger.classList.contains('is-disabled')) {
return false;
}
},
});`

I have search Github for code using the callbacks of the sweet-scroll library without any success.
I hope this does not bother as I feel is more my fault than yours but I am in a complete roadblock.

Thanks for everything in advance!

Experimenting I just discovered that the callbacks are only executed when a method is called but not on the scroll, Is that the desired behavior??

I was asking this myself, and it works as follows:

`document.addEventListener('DOMContentLoaded', function() {
var scroller = new SweetScroll({
// your options

  // After completion
  after: function after(offset, $trigger, scroller) {
    // what needs to be done after completion
  },
}, '#content');

}, false);`
