Statistic
| 参数 | 说明 | 类型 | 默认值 |
|---|---|---|---|
| title | 数值的标题 | string | undefined |
| value | 数值的内容 | string | number | slot | undefined |
| valueStyle | 设置数值的样式 | CSSProperties | {} |
| precision | 数值精度 | number | 0 |
| prefix | 设置数值的前缀 | string | slot | undefined |
| suffix | 设置数值的后缀 | string | slot | undefined |
| separator | 设置千分位标识符 | string | ‘,’ |
| formatter | 自定义数值展示 | Function | (value: string) => value |
创建统计数值组件Statistic.vue
其中引入使用了以下工具函数：
<script setup lang="ts">
import { computed } from 'vue'
import type { CSSProperties } from 'vue'
import { formatNumber, useSlotsExist } from '../utils'
interface Props {
title?: string // 数值的标题 string | slot
value?: string | number // 数值的内容 string | number | slot
valueStyle?: CSSProperties // 设置数值的样式
precision?: number // 数值精度
prefix?: string // 设置数值的前缀 string | slot
suffix?: string // 设置数值的后缀 string | slot
separator?: string // 设置千分位标识符
formatter?: Function // 自定义数值展示
}
const props = withDefaults(defineProps<Props>(), {
title: undefined,
value: undefined,
valueStyle: () => ({}),
precision: 0,
prefix: undefined,
suffix: undefined,
separator: ',',
formatter: (value: string) => value
})
const showValue = computed(() => {
return props.formatter(formatNumber(props.value || '', props.precision, props.separator))
})
const slotsExist = useSlotsExist(['title', 'prefix', 'suffix'])
const showTitle = computed(() => {
return slotsExist.title || props.title
})
const showPrefix = computed(() => {
return slotsExist.prefix || props.prefix
})
const showSuffix = computed(() => {
return slotsExist.suffix || props.suffix
})
</script>
<template>
<div class="m-statistic">
<div v-if="showTitle" class="statistic-title">
<slot name="title">{
{ title }}</slot>
</div>
<div class="statistic-content" :style="valueStyle">
<span v-if="showPrefix" class="statistic-prefix">

</span>
<span class="statistic-value">

{ showValue }}</slot>
</span>
<span v-if="showSuffix" class="statistic-suffix">

{ suffix }}</slot>
</span>
</div>
</div>
</template>
<style lang="less" scoped>
.m-statistic {
font-size: 14px;
color: rgba(0, 0, 0, 0.88);
line-height: 1.5714285714285714;
.statistic-title {

color: rgba(0, 0, 0, 0.45);
font-size: 14px;
}
.statistic-content {

}
}
</style>
在要使用的页面引入
其中引入使用了以下组件：
<script setup lang="ts">
import Statistic from './Statistic.vue'
function formatter (value: string): string {
console.log('value', value)
return '1年有 ' + value + ' 天'
}
</script>
<template>
