一、element使用cron
1、引入vue-cron

npm install vue-cron

2、main.js引入

//全局引入
import VueCron from 'vue-cron'
Vue.use(VueCron);

3、页面使用

<template>
  <div class="cronDemo">
    <el-popover v-model="isShow">
      <el-input slot="reference" @click="cronPopover=true" 
        v-model="cron" placeholder="请输入定时策略" 
        style="width: 40% ;margin-left: -50%">
      </el-input>
      <cronComponent@change="changeCron" @close="cronPopover=false" i18n="cn">
      </cronComponent>
    </el-popover>
  </div>
</template>
 
<script>
  import {cronComponent} from 'vue-cron';
  export default {
    components: { cronComponent},
    data(){
      return {
        isShow: false,
        cron:''
      }
    },
    methods: {
      changeCron(val){
        this.cron=val
      },
    }
  }
</script>

二、Ant Design Vue 使用cron

1、JCronModal.vue

<template>
  <a-modal
    title="corn表达式"
    :width="modalWidth"
    :visible="visible"
    :confirmLoading="confirmLoading"
    @ok="handleSubmit"
    @cancel="close"
    cancelText="关闭">
    <div class="card-container">
      <a-tabs type="card">
        <a-tab-pane key="1" type="card">

          <a-radio-group v-model="result.second.cronEvery">
            <a-row>

            <a-row>
              <a-radio value="2">每隔

二、JCron.vue
需引入JCronModal.vue

<template>
  <div class="components-input-demo-presuffix">
    <a-input @click="openModal" placeholder="corn表达式" v-model="cron" @change="handleOK">
      <a-icon slot="prefix" type="schedule" title="corn控件"/>
      <a-icon v-if="cron" slot="suffix" type="close-circle" @click="handleEmpty" title="清空"/>
    </a-input>
    <JCronModal ref="innerVueCron" :data="cron" @ok="handleOK"></JCronModal>
  </div>
</template>
<script>
  import JCronModal from '@/authority/taskMonitoring/taskManagement/components/JCronModal'
  export default {
    name: 'JCron',
    components: {
      JCronModal
    },
    props: {
      value: {
        required: false,
        type: String,
        default: () => {
          return '* * * * * ? *'
        }
      }
    },
    data () {
      return {
        cron: this.value
      }
    },
    watch: {
      value (val) {
        this.cron = val
      }
    },
    methods: {
      openModal () {
        this.$refs.innerVueCron.show()
      },
      handleOK (val) {
        this.cron = val
        this.$emit('change', this.cron)
        // this.$emit("change", Object.assign({},  this.cron));
      },
      handleEmpty () {
        this.handleOK('')
      }
    },
    model: {
      prop: 'value',
      event: 'change'
    }
  }
</script>
<style scoped>
  .components-input-demo-presuffix .anticon-close-circle {
    cursor: pointer;
    color: #ccc;
    transition: color 0.3s;
    font-size: 12px;
  }
  .components-input-demo-presuffix .anticon-close-circle:hover {
    color: #f5222d;
  }
  .components-input-demo-presuffix .anticon-close-circle:active {
    color: #666;
  }
</style>

3、页面使用
需引入JCron.vue

<j-cron ref="innerVueCron" v-decorator="['cronExpression', {'initialValue':'0/1 * * * * ?',rules: [{ required: true, message: '请输入cron表达式!' }]}]" @change="onChangeCron"></j-cron>

import JCron from '@/authority/taskMonitoring/taskManagement/components/JCron'
components: {
    JCron,
}
onChangeCron (e) {
  this.form.cron = e
}
