我想创建带有样式组件的弹出窗口,并添加淡入和淡出动画。但问题是,当我通过单击 X 按钮关闭弹出窗口时,动画不会播放。这是我的代码:
从 'react' 导入 React, { useRef, Dispatch, SetStateAction }; 从“样式组件”导入样式,{关键帧};导入 { MdClose 作为 PopupClose } 来自 'react-icons/md';
const fadeIn = 关键帧` from { 不透明度:0; }
到{ 不透明度:1; } `;
const fadeOut = 关键帧` from { 不透明度:0; }
到{ 不透明度:1; } `;
常量背景= styled.div<{ref: any, showPopup: boolean}>
;top: 0; bottom: 0; left: 0; right: 0; background: rgba(0, 0, 0, 0.4); position: fixed; display: flex; justify-content: center; align-items: center; transition: all .3s; animation:${props => props.showPopup ? fadeIn : fadeOut} .3s;
const PopupWrapper = styled.div<{noRoundCorners?: boolean}>
;width: 600px; background: #fff; position: relative; z-index: 10; border: 1px solid #DCDCDC; box-sizing: border-box; box-shadow: 0px 4px 16px rgba(67, 67, 67, 0.1); border-radius:${({noRoundCorners})=> noRoundCorners ? '1px' : '40px'}; transition: all .2s;
const PopupContentWrapper = styled.div<{noRoundCorners?: boolean}>`
高度:650 像素;溢出-y:自动;::-webkit-滚动条 { 宽度:10px; }
::-webkit-滚动条-轨道 { 边距底部: ${({noRoundCorners})=> noRoundCorners ? '1px' : '35px'}; 背景颜色:透明; }
::-webkit-scrollbar-thumb { 背景颜色:#3AA4A4; 边框半径:20px; 边框:3px实心透明; 背景剪辑:内容框; } `
const PopupContent = styled.div
;height: 1000px; padding-left: 30px; padding-right: 30px;
const PopupHeader = styled.div
;display: flex;
const 标头 = styled.p
;font-family: Open Sans; font-style: normal; font-weight: bold; font-size: 24px; line-height: 24px; margin-left: 30px;
const ClosePopupButton = styled(PopupClose)
;cursor: pointer; position: absolute; top: 20px; right: 20px; width: 32px; height: 32px; padding: 0; z-index: 10; transition: all .2s;
类型 PopupProps = { 显示弹出窗口:布尔值; noRoundCorners?:布尔值; 标头:字符串; setShowPopup:调度
; 孩子?:React.ReactNode; } export const Popup = ({ showPopup, noRoundCorners, 子项, header, setShowPopup }: PopupProps) => { const PopupRef = useRef();
const closePopup = (e: React.SyntheticEvent) => { if (PopupRef.current === e.target) { setShowPopup(假); } };
返回( <> {显示弹出? ( {标题}
setShowPopup((prev:boolean) => !prev)} /> {孩子们} ) : 无效的} ); };
问题是,一旦您按下关闭按钮,您的组件就会被卸载。
const closePopup = (e: React.SyntheticEvent) => {
if (PopupRef.current === e.target) {
setShowPopup(false);
} };
您可以设置超时时间来观看关闭动画。
const closePopup = (e: React.SyntheticEvent) => {
if (PopupRef.current === e.target) {
setTimeout(function() {
setShowPopup(false);
}, 300);
}
};
