【问题描述】:
我几乎完成了这项工作,但不太确定我做错了什么。当我点击切换按钮时它会滑入,但当我再次点击它时它不会滑出,它只会在动画中重新运行幻灯片。
任何帮助都会很棒
我有以下状态和切换功能
const [close, setClose] = useState(false)
const toggleCart = () => {
setClose(!close)
}
跟随组件
<CartItems close={close} location={location} />
import React, { useState } from "react"
import tw, { styled } from "twin.macro"
import { useTransition, animated } from "react-spring"
const CartWrapper = styled.div`
.test {
position: fixed;
top: 0px;
z-index: 5000;
right: 0;
height: 100vh;
background: lightgrey;
padding: 25px;
}
`
export function CartItems({ location, close }) {
const transitions = useTransition(close, null, {
enter: { transform: "translate3d(100%,0,0)" },
leave: { transform: "translate3d(0%,0,0)" },
})
return (
<>
<CartWrapper>
{transitions.map(({ props }) => {
return (
<animated.div className="test" style={props}>
<h2>Shopping Cart</h2>
{cart}
<p>Total: {formattedTotalPrice}</p>
<form onSubmit={handleSubmitCheckout}>
{/* include validation with required or other standard HTML validation rules */}
<input
name="name"
placeholder="Name:"
type="text"
onChange={e => setName(e.target.value)}
/>
<input
name="giftMessage"
placeholder="Gift Message:"
type="text"
onChange={e => setGiftMessage(e.target.value)}
/>
<input type="submit" />
</form>
<button onClick={clearCart}>Remove all items</button>
</animated.div>
)
})}
{/* <button onClick={handleSubmit}>Checkout</button> */}
</CartWrapper>
</>
)
}
