在Vue3中封装一个可复用的公共CSSProperties

// 目录 /xxx/src/hooks/use-scroll-updown-bottom-content/index.ts 全局定义hooks
import { computed } from 'vue'
import type { CSSProperties } from 'vue'type UpDownOperationType = 'up' | 'down'export const useScrollUpdownBottomContent = (type: UpDownOperationType = 'up',extraHeight = 0
) => {const style = computed<CSSProperties>(() => {const style: CSSProperties = {}if (type === 'up') {style.transform = `translateY(calc(100% + ${extraHeight}px))`} else if (type === 'down') {style.transform = `translateY(calc(100% - ${extraHeight}px))`}style.transitionDuration = '0.25s'style.transitionTimingFunction = 'linear'style.transitionProperty = 'transform'return style})return {style}
}

// 目录 xxx/pages/pages/index.vue 业务组件中使用
import { useScrollUpdownBottomContent } from '@/hooks'
const { style: authInfoScrollStyle } =  useScrollUpdownBottomContent('up', 80)
console.log(authInfoScrollStyle)
// {
//   "transform": "translateY(calc(100% + 80px))",
//   "transitionDuration": "0.25s",
//   "transitionTimingFunction": "linear",
//   "transitionProperty": "transform"
// } 

简单例子,TypeScript中定义CSS Properties
在多个地方重复使用此样式信息，提高代码的可复用性。

interface CustomStyles {backgroundColor: string;color: string;fontSize: string;
}const customStyles: CustomStyles = {backgroundColor: 'blue',color: 'white',fontSize: '16px'
};
