Vue3利用父子组件实现字典

子组件

<template>
    <div>
        <el-tag :type="tagType" v-if="tagVisible">{{ tagText }}</el-tag>
    </div>
</template>


<script setup>
import { defineProps, onMounted, ref } from 'vue'

const tagVisible = ref(false);
const tagType = ref("info");
const tagText = ref("");

// 定义参数 已经选中的ITEMID
const props = defineProps({
  dictType: {
    type: String, //参数类型
    default: String, //默认值
    required: true, //是否必须传递
  },
  dictValue: {
    type: String, //参数类型
    default: String, //默认值
    required: true, //是否必须传递
  }
})

const lastLogStatusDict = [
  {
    dictValue: 0,
    tagType: "primary",
    tagText: "运行中"
  },
  {
    dictValue: 1,
    tagType: "primary",
    tagText: "运行中"
  },
  {
    dictValue: 2,
    tagType: "danger",
    tagText: "异常"
  }
]

// //周期函数
onMounted(() => {
	//打印父组件传递的值
  // console.log(props.dictType, 'dictType');
  // console.log(props.dictValue, 'dictValue');

  const dictType = props.dictType;
  const dictValue = props.dictValue;
  
  if(dictValue==null){
    return;
  }
  tagVisible.value = true;

  if(dictType == "lastLogStatus"){
      tagType.value = lastLogStatusDict[dictValue].tagType;
      tagText.value = lastLogStatusDict[dictValue].tagText;
  }

})
</script>

<DictTag dictType="lastLogStatus" :dictValue="scope.row.lastLogStatus"/>

import DictTag from '@/components/dict/index.vue'
