Vue3统计数值（Statistic）

可自定义设置以下属性：

数值的标题（title），类型：string | slot，默认：‘’
数值的内容（value），类型：string | number，默认：‘’
设置数值的样式（valueStyle），类型：CSSProperties，默认：{}
数值精度（precision），类型：number，默认：0
设置数值的前缀（prefix），类型：string | slot，默认：‘’
设置数值的后缀（suffix），类型：string | slot，默认：‘’
设置千分位标识符（separator），类型：string，默认：‘,’
自定义数值展示（formatter），类型：Function，默认：(value: string) => value

效果如下图：在线预览

创建统计数值组件Statistic.vue

<script setup lang="ts">
import { ref, computed, onMounted } from 'vue'
import type { CSSProperties } from 'vue'
import { moneyFormat } from '../index'
interface Props {
  title?: string // 数值的标题 string | slot
  value?: string|number // 数值的内容
  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: '',
  value: '',
  valueStyle: () => { return {} },
  precision: 0,
  prefix: '',
  suffix: '',
  separator: ',',
  formatter: (value: string) => value
})
const showValue = computed(() => {
  return props.formatter(moneyFormat(props.value, props.precision, props.separator))
})
const prefixRef = ref() // 声明一个同名的模板引用
const showPrefix = ref(1)
const suffixRef = ref() // 声明一个同名的模板引用
const showSuffix = ref(1)
onMounted(() => {
  showPrefix.value = prefixRef.value.offsetHeight
  showSuffix.value = suffixRef.value.offsetHeight
})
</script>
<template>
  <div class="m-statistic">
    <div class="u-title">
      <slot name="title">{{ title }}</slot>
    </div>
    <div class="m-content" :style="valueStyle">
      <span ref="prefixRef" class="u-prefix" v-if="showPrefix">
        <slot name="prefix">{{ prefix }}</slot>
      </span>
      <span class="u-content-value">{{ showValue }}</span>
      <span ref="suffixRef" class="u-suffix" v-if="showSuffix">
        <slot name="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;
  .u-title {
    margin-bottom: 4px;
    color: rgba(0, 0, 0, 0.45);
    font-size: 14px;
  }
  .m-content {
    color: rgba(0, 0, 0, 0.88);
    font-size: 24px;
    .u-prefix {
      display: inline-block;
      margin-inline-end: 4px;
    }
    .u-content-value {
      display: inline-block;
      direction: ltr;
    }
    .u-suffix {
      display: inline-block;
      margin-inline-start: 4px;
    }
  }
}
</style>

在要使用的页面引入

其中引入使用了 Vue3栅格（Grid） Vue3卡片（Card）

<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>
