1、组件页面

<template>
  <!-- 时间点选择组件 -->
  <div class="m-select-wrap">
    <input
      :class="['u-select-input f16', color === 'blue' ? '' : 'white-color']"
      type="text"
      readonly
      @click="openSelect"
      @blur="onBlur"
      v-model="selectName" />
    <div :class="['triangle-down', { 'rotate': rotate }]"></div>
    <div :class="['m-options-panel f16', showOptions ? 'show': 'hidden']">
      <div class="flexBox">
      <p @mousedown="getValue(item.name, item.value, index)" v-for="(item, index) in selectData" :key="index">
        <!-- status
             1蓝色：已上报并上报成功
             2红色：已上报但上报失败
             3绿色：有数据但未上报
             4灰色：无数据(时间未到)

</style>

2、使用页面

        2.1 引入js

import Select from "./components/selectmodel"

        2.2 在components注册

components: {
      Select
},

        2.3使用

<Select
                :selectData="selectData"
                :selValue="selValue"
                color="white"
                :selName="selName"
                v-model="queryParam.ptime"
                @getValue="getValue" />

        2.4 写方法

getValue (name, value, index) {
        this.queryParam.ptime = value;
      },
