import {ref} from 'vue';
  export default {
    name: 'SearchInput',
    props: {
      placeholder: String,
      maxlength: Number
    },
    setup(){
      const inputValue = ref('');
      const searchData = (e) => {
        
      }
      return {
        inputValue,
        searchData
      }

src\store\mutations.js

添加新的逻辑

export default {
  setHeaderTitle(state, routerName) {
    switch (routerName) {
      case 'day':
        state.headerTitle = '当天信息'
        break

        break
      case 'year':
        state.headerTitle = '当年假期'
        break
      default:
        state.headerTitle = '当天信息'
        break
    }
  },
  /**
   * 设置输入框最大长度
   * @param {*} state
   * @param {*} routerName
   */

      case 'month':
        state.maxlength = 6
        break
      case 'year':
        state.maxlength = 4
        break
      default:
        state.maxlength = 8
        break
    }
  },
  /**
   * 设置输入框提示信息
   * @param {*} state
   * @param {*} routerName
   */
  setPlaceholder(state, routerName) {
    const date = new Date()

    let year = date.getFullYear(),
      month = date.getMonth() + 1,
      day = date.getDate()

    month = month < 10 ? '0' + month : month
    day = day < 10 ? '0' + day : day

    switch (routerName) {
      case 'day':
        state.placeholder = `格式：${year}${month}${day} （${year}年${month}月${day}日）`
        break
      case 'month':
        state.placeholder = `格式：${year}${month} （${year}年${month}月）`
        break
      case 'year':
        state.placeholder = `格式：${year} （${year}年）`

        break
    }
  },
}

src\App.vue

监听路由变化，重新更新输入框最大长度和提示信息缓存数据

<search-input :placeholder='placeholder' :maxlength='maxlength'></search-input>

// 监听路由变化，设置 header 标题
    watch(
      () => router.currentRoute.value.name,
      (value) => {
        store.commit('setHeaderTitle', value)
        store.commit('setPlaceholder', value)
        store.commit('setMaxlength', value)
      }
    )
