TweenMax 悬停不触发动画

Question

我正在尝试更改带有边框的 div 的宽度，鼠标悬停在另一个 div 的 link 上，但悬停不返回宽度回到 0。

function over(){
  TweenMax.to($(".grid-item-20"), 1, {
        width: "50%",
        ease: Expo.easeInOut
  });
};

function out(){
  TweenMax.to($("grid-item-20"), 1, {
        width: "0",
        ease: Expo.easeInOut,
  });
};

$(".grid-item-17 a").hover(over, out);

.grid-item-20 {
  border-bottom: 1px solid #000;
  width: 0%;
}

<div class="grid-item-17">

  <a href="#">Home</a>

</div>


<div class="grid-item-20">

</div>

您的选择器上缺少 dot

function out(){
  TweenMax.to($(".grid-item-20"), 1, {
        width: "0",
        ease: Expo.easeInOut,
  });
};

function over(){
  TweenMax.to($(".grid-item-20"), 1, {
        width: "50%",
        ease: Expo.easeInOut
  });
};

function out(){
  TweenMax.to($(".grid-item-20"), 1, {
        width: "0",
        ease: Expo.easeInOut,
  });
};

$(".grid-item-17 a").hover(over, out);

.grid-item-20 {
  border-bottom: 1px solid #000;
  width: 0%;
}
