Vue2进度条（Progress）
可自定义设置以下属性：
进度条宽度（width），单位 px，类型：string | number，默认 undefined；type: 'line' 时，为进度条宽度，默认值 '100%'；type: 'circle' 时，为进度圈宽高，默认值 120
当前进度百分比（percent），类型：number，默认 0
进度条的尺寸（lineSize），单位 px，类型：number，默认 undefined；type: 'line' 时，为进度条线高，默认值 8；type: 'circle' 时，单位是进度圈画布宽度的百分比，默认值 6
进度条的色彩（lineColor），类型：string | {'0%'?: string, '100%'?: string, from?: string, to?: string, direction?: 'left'|'right'}，默认 undefined；传入 string 时为纯色，传入 object 时为渐变，进度圈时 direction: 'left' 为逆时针，direction: 'right' 为顺时针
进度条边缘的形状（lineCap），类型：'round' | 'square'，默认 'round'
是否显示进度数值或状态图标（showInfo），类型：boolean，默认 true
进度数值或状态图标的尺寸（infoSize），单位 px，类型：number，默认 undefined；type: 'line' 时，默认值 14；type: 'circle' 时，默认值 undefined
进度完成时的信息（success），类型：string | slot，默认 undefined
内容的模板函数（format），类型：(percent: number) => (string | number) | slot，默认：(percent: number) => percent + '%'
进度条类型（type），类型：'line' | 'circle'，默认 'line'

①创建进度条组件Progress.vue：
其中引入使用了以下工具函数：
- 监听插槽存在 useSlotsExist
获取依赖注入 useInject
<script setup lang="ts"> import { computed } from 'vue' import { useSlotsExist, useInject } from 'components/utils' export interface Gradient { '0%'?: string '100%'?: string from?: string to?: string direction?: 'left' | 'right' // 默认 'right' } export interface Props { width?: number | string // 进度条宽度，单位 px；type: 'line' 时，为进度条宽度，默认值 '100%'；type: 'circle' 时，为进度圈宽高，默认值 120 percent?: number // 当前进度百分比 lineSize?: number // 进度条的尺寸，单位 px；type: 'line' 时，为进度条线高，默认值 8；type: 'circle' 时，单位是进度圈画布宽度的百分比，默认值 6 lineColor?: string | Gradient // 进度条的色彩，传入 string 时为纯色，传入 Gradient 时为渐变，进度圈时 direction: 'left' 为逆时针，direction: 'right' 为顺时针 lineCap?: 'round' | 'butt' // 进度条边缘的形状 showInfo?: boolean // 是否显示进度数值或状态图标 infoSize?: number // 进度数值或状态图标的尺寸，单位 px；type: 'line' 时，默认值 14；type: 'circle' 时，默认值 24 success?: string // 进度完成时的信息 string | slot format?: (percent: number) => string | number // 内容的模板函数 function | slot type?: 'line' | 'circle' // 进度条类型 } const props = withDefaults(defineProps<Props>(), { width: undefined, percent: 0, lineSize: undefined, lineColor: undefined, lineCap: 'round', showInfo: true, infoSize: undefined, success: undefined, format: (percent: number) => percent + '%', type: 'line' }) const { colorPalettes } = useInject('Progress') // 主题色注入 const slotsExist = useSlotsExist(['success']) // 进度条宽度/进度圈宽高 const progressSize = computed(() => { if (props.width === undefined) { if (props.type === 'line') { return '100%' } if (props.type === 'circle') { return '120px' } } return typeof props.width === 'number' ? `${props.width}px` : props.width }) // 进度条高度；进度圈线宽 const progressLineSize = computed(() => { if (props.lineSize === undefined) { if (props.type === 'line') { return 8 } if (props.type === 'circle') { return 6 } } return props.lineSize as number }) // 进度条/圈进度数值或状态图标尺寸 const progressInfoSize = computed(() => { if (props.infoSize === undefined) { if (props.type === 'line') { return '14px' } if (props.type === 'circle') { return '24px' } } return `${props.infoSize}px` }) // 圆条周长 const perimeter = computed(() => { return (100 - progressLineSize.value) * Math.PI }) // 圆条轨道路径指令 const path = computed(() => { const long = 100 - progressLineSize.value return `M 50,50 m 0,-${long / 2} a ${long / 2},${long / 2} 0 1 1 0,${long} a ${long / 2},${long / 2} 0 1 1 0,-${long}` }) // 是否为渐变色 const isGradientColor = computed(() => { if (props.lineColor !== undefined && typeof props.lineColor !== 'string') { return true } return false }) // 进度条/圈颜色 const lineColorComputed = computed(() => { if (props.lineColor === undefined) { return colorPalettes.value[5] } else if (typeof props.lineColor === 'string') { return props.lineColor } else { return `linear-gradient(to ${props.lineColor.direction || 'right'}, ${props.lineColor['0%'] || props.lineColor.from}, ${props.lineColor['100%'] || props.lineColor.to})` } }) // 进度圈渐变色 id const circleGradient = computed(() => { if (isGradientColor.value) { const gradientColor = props.lineColor as Gradient if (gradientColor.direction === undefined || gradientColor.direction === 'right') { return `right-${gradientColor['0%'] || gradientColor.from}-${gradientColor['100%'] || gradientColor.to}` } return `left-${gradientColor['100%'] || gradientColor.to}-${gradientColor['0%'] || gradientColor.from}` } return null }) const circleColorFrom = computed(() => { if (isGradientColor.value) { const gradientColor = props.lineColor as Gradient if (gradientColor.direction === undefined || gradientColor.direction === 'right') { return gradientColor['0%'] || gradientColor.from } else { return gradientColor['100%'] || gradientColor.to } } return }) const circleColorTo = computed(() => { if (isGradientColor.value) { const gradientColor = props.lineColor as Gradient if (!gradientColor.direction || gradientColor.direction === 'right') { return gradientColor['100%'] || gradientColor.to } else { return gradientColor['0%'] || gradientColor.from } } return }) const showPercent = computed(() => { return props.format(props.percent > 100 ? 100 : props.percent) }) const showSuccess = computed(() => { return slotsExist.success || props.success }) </script> <template> <div v-if="type === 'line'" class="progress-line-wrap" :style="` --progress-size: ${progressSize}; --progress-primary-color: ${lineColorComputed}; --progress-success-color: #52c41a; --progress-font-size: ${progressInfoSize}; --progress-border-radius: ${lineCap === 'round' ?
