jQuery Waypoints仅处理具有指定类的第一个元素

Question

I am trying to implement the jQuery Waypoints plugin to add an .active class to any element with a .foo class as it gets into the viewport:

<div class="foo"></div>
<div class="foo"></div>

var inview = new Waypoint.Inview({
  element: $('.foo')[0],
  entered: function(direction) {
    $(this.element).addClass("active");
  }
});

JS Fiddle: http://jsfiddle.net/g6mouxnd/

The example above will add the .active class to the first .foo container only. How do I make it work for the second and any subsequent .foo container as well?

Answer 1

You can loop over every .foo and create an Inview for each:

$('.foo').each(function() {
  new Waypoint.Inview({
    element: this,
    entered: function(direction) {
      $(this.element).addClass('active');
    }
  });
});
