How to detect direction

[ukropf]

How i can to detect scroll direction (up or down) in beforeMove callback function?

I did it this way, not sure the best way, but it worked for me
In the onepagescroll setup script:

var prevIndex = 1;
jQuery(".main").onepage_scroll({
...
afterMove: function(index) {
...
prevIndex = parseInt(jQuery('body').attr('class').substr(jQuery('body').attr('class').indexOf('viewing-page-')+13)); //at the very end of afterMove method
},

Then I check whether prevIndex is less or more than index variable where I need it and it works for me.

Easiest would be like this:

    $(document).ready(function(){

      var prevIndex = 1;

      $(".main").onepage_scroll({
        sectionContainer: "section",
        responsiveFallback: 600,
        loop: true,
        afterMove: function(index) {
          if (prevIndex<index) {
            // move next page
            console.debug("next > afterMove("+index+") prvIdx:"+prevIndex);
          } else {
            // move prev page
            console.debug("prev > afterMove("+index+") prvIdx:"+prevIndex);
          }
          prevIndex = index; //at the very end of afterMove method
        }
      });

    });
