vue3+elementPlus实现年份选择器

作者:乐了个乐

这篇文章主要为大家详细介绍了vue3如何通过elementPlus实现一个简单的年份选择器,文中的示例代码讲解详细,需要的小伙伴可以跟随小编一起学习一下

下面是vue3结合elementPlus实现简单年份选择器的示例代码,希望对大家有所帮助

1.组件

<template>
  <div class="year-range-picker">
    <el-date-picker
      v-model="startYear"
      type="year"
      :placeholder="config['archivesCenter:archiveList:startYear']"
      size="mini"
      class="year-picker"
      style=" max-width: 150px !important;"
      @change="changeStartYear"
      format="YYYY"
       value-format="YYYY"
    >
    </el-date-picker>
    <span class="range-word"> {{config['archivesCenter:archiveList:to']}} </span>
    <el-date-picker
      v-model="endYear"
      type="year"
       :placeholder="config['archivesCenter:archiveList:endYeare']"
      size="mini"
      class="year-picker"
      style=" max-width: 150px !important;"
      @change="changeEndYear"
      format="YYYY"
      value-format="YYYY"
    >
    </el-date-picker>
  </div>
</template>
 
<script setup lang="ts">
//导入多语言配置
import {languageData} from '~/stores/global'
import { ElMessage } from 'element-plus'
 
const config:any = computed(() => languageData().languageConfig.config);
interface IProps {
 yearRange:Array
}
const props = withDefaults(defineProps<IProps>(), {
  yearRange:[]
})
//绑定年份
const startYear =ref("")
const endYear =ref("")
const emits =defineEmits(['yearChanged'])
watchEffect(()=>{
     startYear.value = String(props.yearRange[0]);
     endYear.value = String(props.yearRange[1]);
     
})
 
const  changeStartYear=(val) =>{
       if (Number(val)&&Number(endYear.value)&&(Number(startYear.value) > Number(endYear.value))) {
        startYear.value = ''
        return   ElMessage.error(config.value['archivesCenter:archiveList:timeTip'])
      }
      if (val) {
         startYear.value = val;
      }
      let times=[Number(startYear.value) || '', Number(endYear.value) || '']
 
      // 将改动传回父组件
      emits("yearChanged", times);
    }
const   changeEndYear=(val) =>{
      if (Number(val)&&Number(startYear.value)&&(Number(startYear.value) > Number(endYear.value))) {
          endYear.value = ''
        return   ElMessage.error(config.value['archivesCenter:archiveList:timeTip'])
      }
 
      if (val) {
          endYear.value = val;
      }
      let times=[Number(startYear.value) || '', Number(endYear.value) || '']
 
     emits("yearChanged", times)
    }
</script>
 
 
<style scoped lang="less">
.year-range-picker {
  color: black;
  text-align: center;
  font-size: 18px;
}
 
.range-word {
  margin-left: 10px;
  margin-right: 10px;
}
 
 .year-picker {
  max-width: 100px !important;
}
</style>

2.组件使用

    <!-- :yearRange 为父组件向子组件传参 -->
    <!-- :key 保证父组件的数据更新后,重新渲染子组件,使子组件也同步更新 -->
    <!-- @yearChanged 监听子组件向父组件传参 -->
           <yearRangePicker
            :yearRange="yearRange"
            :key="`${yearRange[0]}_${yearRange[1]}`"
            @yearChanged="handleYearChanged"
                  >
          </yearRangePicker>`
