我正在尝试使用JQuery和框架anime.js

为我的页面加载器实现for循环



    var testimonialElements = $(".loader-animation");
    for(var i=0; i< Elements.length; i++){
        var element = Elements.eq(i);
        //do something with element
    
         var basicTimeline = anime.timeline();
           basicTimeline
      .add({
        targets: element,
        opacity: {
        value: ['1','0'],
        duration: 2000,
        delay: 4000
      },
      letterSpacing: {
        value: ['30px','10px'],
        duration: 2000,
        easing: 'easeInOutSine'
      }
    });
        }
&#13;
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="container on-loader">	
    	<h2 class="loader-animation">Case1</h2>
    <h2 class="loader-animation">Case2</h2>
    <h2 class="loader-animation">Case3</h2>
    <h2 class="loader-animation">Case4</h2>
    </div>
&#13;
&#13;
&#13;

问题是,脚本没有循环并为每个循环启动动画。

非常抱歉,如果问题很简单,我是javascript&amp; anime.js框架。

答案 0 :(得分:0)

没有必要使用循环,首先你将.loader-animation选择器传递给你的动漫,你只需要使用callback函数,在该函数中它返回当前元素,它就是&#39;所有元素之间的顺序(1,2,3 ......)并将延迟乘以最后的顺序: (在你可以延迟第二次玩到甜蜜的意图之后)

见下面的工作代码段

&#13;
&#13;
var basicTimeline = anime.timeline();
basicTimeline.add({
  targets: ".loader-animation",
  opacity: {
    value: ['1', '0'],
    duration: 2000,
    delay: function(el, i) {
      $(el).removeClass("otherclass");
      return 2000 * (i + 1);
    },
  },
  letterSpacing: {
    value: ['30px', '10px'],
    duration: 2000,
    easing: 'easeInOutSine',
    delay: function(el, i) {
      return 2000 * (i);
    }
  }
});
