初始化插件

在页面 DOM 元素加载完毕之后,通过下面的方法来初始化该特效。

  1. $('.coidea-horizontal').imagesLoaded(function() {
  2.     $('.loader').addClass('is-loaded');
  3.  
  4.     var totalWidth = 0,
  5.         timeline = new TimelineMax({ paused: true });
  6.  
  7.     // set width of our scrolling div
  8.     $('.horizontal-container').each(function(index) {
  9.       totalWidth += parseInt($(this).width(), 10);
  10.     });
  11.     $('.coidea-horizontal').css({
  12.       'width': totalWidth
  13.     })
  14.  
  15.     // timeline
  16.     timeline.staggerTo('.image', 0.75, {
  17.         scaleX: 1.20,
  18.         transformOrigin: "right",
  19.         ease: Back.easeOut.config(0.5)
  20.       })
  21.       .staggerTo('.image', 0.75, {
  22.         scaleX: 1,
  23.         transformOrigin: "right",
  24.         ease: Back.easeOut.config(0.5)
  25.       }, 0, '-=0.5');
  26.  
  27.     // mouse wheel
  28.     window.addEventListener("wheel", onWheel);
  29.     // mouse wheel - firefox
  30.     window.addEventListener('DOMMouseScroll', onWheel);
  31.     // touch mobile
  32.     window.addEventListener("touchmove", onWheel);
  33.  
  34.     // main function
  35.     function onWheel(event) {
  36.  
  37.       event.preventDefault();
  38.       var normalized,
  39.           delta = event.wheelDelta,
  40.           scroll = (window.pageXOffset || document.scrollLeft) - (document.clientLeft || 0) || 0;
  41.       if (delta) {
  42.  
  43.         normalized = (delta % 120) == 0 ? -delta / 120 : -delta / 3;
  44.       } else {
  45.  
  46.         delta = event.deltaY || event.detail || 0;
  47.         normalized = -(delta % 3 ? delta * 10 : delta / 3);
  48.       }
  49.  
  50.       timeline.play().restart();
  51.  
  52.       TweenLite.to(window, 0.4, {
  53.         scrollTo: {
  54.           x: scroll + 200 * normalized
  55.         }
  56.       });
  57.     }
  58.   });
  59.  
  60.   // fast fix for resize window and refresh view, attention: not use in production!
  61.   window.onresize = function(){ location.reload(); }
