jquery 无法在 'animate' : Partial keyframes are not supported 上执行 'Element'

Question

我有以下代码。我正在尝试对 png 进行动画处理，使其看起来有拉伸(stretch)效果。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，就像在其他函数中使用一样。

任何帮助将不胜感激

$("#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>

Answer 1

您正在 $("#light-switch")[0] 的索引中搜索，这是错误的。你不需要定义它。这将直接起作用 $("#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>
