jQuery .animate()切換到GSAP TweenMax

[英]jQuery .animate() switch to GSAP TweenMax

我正在做一個項目,該項目以不同的速度快速連續地對單個單詞進行動畫處理。 我已經使用jQuery.animate()和回調程序制作了一些快速而骯臟的東西來制作此動畫。

您也可以在Codepen和下面的代碼上看到一個示例(相當大)。

我想知道如何將其轉換為使用GSAP 以下是我目前正在替代jQuery的.animate()並且該版本的Codepen也位於此處

TweenMax.staggerFromTo('.frame', 1, { opacity: 0, delay: 1 }, { opacity: 1, delay: 1 }, 1);

如您所見,我的GSAP版本無法像我的快速jQuery版本一樣正常工作。

您還可以看到,在我巨大的jQuery可怕文件中,我可以輕松地修改每個幀的速度,這一點非常重要,因此我也需要能夠使用GSAP版本來做到這一點。

我該怎么辦?

首先,請閱讀我的答案之一,如果您以前從未聽說過或嘗試過GSAP ,則可以通過大量鏈接向您介紹 GSAP

其次,您的Codepen不適用於Chrome(45 +,Macbook Pro),但適用於Firefox。 我不確定是什么原因,但我想是關於安全性的。

無論如何,由於callbacks-inin-callbacks循環:),您的jQueryanimate()調用很難理解:即使我們繼續使用animate() ,我也不知道是否會有更好的方法來實現它們。 animate()

話雖如此,使用GSAP制作所有動畫的決定必須受到鼓掌:)

可以在此處找到Codepen URL,這是最終JavaScript的樣子:

var timeline = new TimelineMax({ paused: true });
var easeOut = Power2.easeOut;
var easeIn = Power2.easeIn;
var durationRegular = 0.2;
var durationSlow = 0.8;
var durationFast = 0.1;
var pauseLocation = 5;
var pauseInterval = 2;
var container = $('#ad-container'), content = $('#ad-content');
var bannerInit = function() { showBanner(); };
var showBanner = function() {
  content.removeClass('loading');
  $('#preloader').addClass('off');
  anim();
};
var anim = function() {
  var frames = $('.frame');
  var numFrames = frames.length;
  var dataSpeed = '';
  TweenMax.set(frames, { autoAlpha: 0 });
  timeline
    .to(frames[0], 1, { autoAlpha: 1, ease: easeOut })
    .to(frames[0], durationRegular, { autoAlpha: 0, ease: easeIn });
  for (var i = 1; i < numFrames; i += 1) {
    dataSpeed = $(frames[i]).data('speed');
    var duration = durationRegular;
    if (dataSpeed === 'slowPace') {
      duration = durationSlow;
    } else if (dataSpeed === 'fastPace') {
      duration = durationFast;
    }
    timeline
      .to(frames[i], duration, { autoAlpha: 1, ease: easeOut })
      .to(frames[i], duration, { autoAlpha: 0, ease: easeIn });
  }
  timeline.play();
  timeline.addPause(pauseLocation, onTimelinePaused);
};
var onTimelinePaused = function() {
  TweenMax.delayedCall(pauseInterval, function() {
    timeline.resume();
  });
};
//
bannerInit();

這里使用的GSAP的主要功能稱為TimelineMax ,可以在此處找到其文檔。
