uniapp微信小程序自定義封裝分段器。

話不多說先上效果

這里我用的是cil框架 vue3 下面貼代碼
組價(jià)代碼：

<template>
  <view class="page">
    <view
      v-for="(item, index) in navList"
      :key="index"
      @click="changeNav(index)"
      :class="current == index ? 'selectNav' : ''"
      >{{ item.title }}{{ item.num ? "（" + item.num + "）" : "" }}</view
    >
  </view>
</template>

<script setup lang="ts">
import { ref, reactive, watch } from "vue";
const emit = defineEmits(["changeNav"]);
const props = withDefaults(
  defineProps<{
    navList: any;
    currentNav?: number;
  }>(),
  { navList: [], currentNav: 0 }
);
const current = ref<number>(props.currentNav);
const changeNav = (index: number) => {
  current.value = index;
  emit("changeNav", current.value);
};
</script>

<style lang="scss" scoped>
.page {
  width: 100%;
  height: 88rpx;
  background-color: #fff;
  display: flex;
  align-items: center;
  justify-content: space-around;
  font-size: 30rpx;
  color: #14131f;
}

.selectNav {
  color: #00cd73;
  font-size: 34rpx;
  position: relative;
  font-weight: 600;
}

.selectNav::after {
  content: "";
  position: absolute;
  bottom: -20rpx;
  left: 0%;
  width: 90rpx;
  height: 10rpx;
  background: #00cd73;
  border-radius: 5rpx;
}
</style>

父組件使用方法：文章來源地址http://www.zghlxwxcb.cn/news/detail-759217.html

<template>
  <view class="page">
    <Sectionalizer :navList="navList" @changeNav="changeNav"></Sectionalizer>
  </view>
</template>
<script setup lang="ts">
import { ref, reactive } from "vue";
import Sectionalizer from "@/components/sectionalizer.vue";
const navList = ref<any>([
  {
    title: "未進(jìn)行",
    num: 5,
  },
  {
    title: "進(jìn)行中",
    num: 2,
  },
  {
    title: "已完成",
    num: 12,
  },
]);
const changeNav = (index: number) => {
  console.log(index);
};
</script>
