jquery 无法在 'Element' 上执行 'animate'：不支持部分关键帧

Question

我有以下代码。我正在尝试为 png 设置动画，使其看起来可以拉伸。但是当代码运行时，我收到错误：无法在 'Element' 上执行 'animate'：不支持部分关键帧。

Jquery 在文档上初始化，因为它在其他函数中使用。

如有任何帮助，我们将不胜感激

$("#light-switch")[0].animate(
    {height: "30%"} ,500, function(){
      console.log("moved")
 });

#light-switch{
   z-index: 5;
   width: 10%;
   height: 25%;
   position: absolute;
   top:63%;
   right:20%;
 }

<div class="clickable" id="light-switch-link" >
      <img id="light-switch" src="./images/switch-on.png" alt="light_switch"  />
</div>

您正在搜索 $("#light-switch")[0] 的索引，但这是错误的。你不需要定义它。这将直接工作 $("#light-switch").animate(.

这对你有用。

$("#light-switch").animate(
    {height: "30%"} ,500, function(){
      console.log("moved")
 });

#light-switch{
   z-index: 5;
   width: 10%;
   height: 25%;
   position: absolute;
   top:63%;
   right:20%;
 }

<div class="clickable" id="light-switch-link" >
      <img id="light-switch" src="./images/switch-on.png" alt="light_switch"  />
</div>
