【问题描述】：

您好，我正在尝试向右设置动画，但它似乎不起作用，但不透明度更改确实在同一功能中起作用？

$(document).on("click touchstart tap", ".buttonchat", function () 
   
$('.message').each(function(i) 
   delay =(i)*500;
   
     $(this).delay(delay).animate(
    opacity: 0,
   right: "-150px"

  ,1000, function() 
    // Animation complete.
  );
   
   
 );
 );

正如您在这支笔中看到的那样，向右动画只会改变不透明度，这是怎么回事？ 笔：https://codepen.io/uiunicorn/pen/YzZXwJp

提前致谢

【参考方案1】：

您的消息跨度必须具有position: absolute 属性...

<span class="message" style="width: 18.2105rem; height: 1.26316rem; opacity: 1; position:absolute;">Hello! ? I hope you're having a good night</span>

这是W3 Schools的解释：

默认情况下，所有 html 元素都有一个静态位置，并且不能 感动。要操纵位置，记得先设置CSS 将元素的位置属性设置为相对、固定或绝对！

【讨论】：

或position: relative，这取决于您要实现的其他目标

【参考方案2】：

您应该考虑在 CSS 文件中添加“.”在一开始的时候。 和 Js 文件在下面进行更正。

 $(document).on("click touchstart tap", ".buttonchat", function () 
   
   
   
   $('.message').each(function(i) 
   delay =(i)*500;
   
     $(this).delay(delay).animate(
    "opacity": 0.20 ,
   "right": "0px" , "top": "0px" ,  "background-color" : "green"  

  ,1000, function() 
    // Animation complete.
 
  );
   
   
 );
 );

.message
  left: 0px;
position : absolute ; 
  
  
.relative position : relative ;
