18种基于anime.js的文字动画特效

// Initialize
var txt = new TextFx(this.el.querySelector('.title'));
 
// Show letters: 
// txt.show([effect] [,callback]);
// If nothing is passed, then there's no animation.
// ´effect´ can either be one of the predefined effects: ['fx1',...,'fx17'] or 
// an object literal representing both, in and out animations (anime.js based).
 
// Example:
effect = {
  in: {
    duration: 500,
    delay: function(el, index) { 
      return 250+index*40; 
    },
    easing: 'easeOutExpo',
    opacity: 1,
    translateY: ['50%','0%']
  },
  out: {
    duration: 500,
    delay: function(el, index) { 
      return index*40; 
    },
    easing: 'easeOutExpo',
    opacity: 0,
    translateY: '-50%'
  }
}
// ´callback´ is the callback function, after all the letters finished the animation.
 
// Hide letters: 
// txt.hide([effect] [,callback]); (same logic of show)
