Vue3全局封装modal弹框使用：

应用场景：全局动态form表单弹框
应用Vue3碎片： ref，reactive，app.component，defineExpose，defineProps，defineEmits
应用UI: element-plus dialog form

一.封装

1.引入
main.js

import App from './App.vue'
import ModalPanel from "@/components/element/ModalPanel.vue";
const app=createApp(App)
app.component('ModalPanel',ModalPanel)

2.使用

  <ModalPanel  
    :defineWidth="defineWidth" 
    :selSingle="selSingle"
    :editTitle="editTitle"
    :editType="editType"
    :editForm="editForm"
    :fixedParam="fixedParam"
    :randomParam="randomParam"
    @updateData="declareData"
    @updateShow="updateSingShow"
    :key="modalPannelKey"
   />

开启

const openModalPannel = () => {
  defineWidth.value=500;
  editType.value="add";
  editTitle.value="操作";
  fixedParam.value=[
  { name:"XX",value:"name"},
  ];
   randomParam.value=[
  { name:"xy",value:"name"},
  ];
}

关闭

const updateSingShow = () => {
  selSingle.value=false;
}

接收

const declareData= (data) => {
   //do...
}

二.具体封装

1.接收参数

const selSingleShow = ref(false);
const props = defineProps({
  defineWidth: {
    required: true,
    type: Number,
    default: 0,
  },
  selSingle: {
    required: true,
    type: Boolean,
    default: "",
  },
  editTitle: {
    required: true,
    type: String,
    default: "",
  },
  editType: {
    required: true,
    type: String,
    default: "",
  },
  editForm: {
    required: true,
    type: Object,
    default: {},
  },
  fixedParam: {
    required: true,
    type: Array,
    default: [],
  },
  randomParam: {
    required: true,
    type: Array,
    default: [],
  },
});
const emit = defineEmits(['updateData','updateShow']);
const formList = reactive([]);

2.初始化值

onMounted(() => {
  if(props!=undefined){
        formList.push(...props.fixedParam);
        formList.push(...props.randomParam);
       selSingleShow.value=props.selSingle;
    }
});

3.关闭弹框

const  updateSingle=()=>{
  emit("updateShow",selSingleShow);
}

4.更新数据

const updateNameChange=(data)=> {
    emit("updateData",data);
}

5.弹框

 <el-dialog
      v-model="selSingleShow"
      :title="editTitle"
      :width="defineWidth"
      align="left">
      <div class="modal-padding">
        <el-form
          ref="ruleFormRef"
          label-width="auto"
          label-position="top"
          :model="editForm"
          :rules="rules"
          class="demo-ruleForm"
        >
        <div v-for="(item, index) in formList">
          <el-form-item :label="item.name" :prop="item.value">
            <el-input v-model="editForm[item.value]" />
          </el-form-item>
        </div>
        </el-form>
      </div>
      <template #footer>
        <div class="modal-footer-padding">
          <el-button  type="primary"
            >确认</el-button
          >
          <el-button >取消</el-button>
        </div>
      </template>
    </el-dialog>

三，交互

1.组件暴露方法

import { ref, reactive, onMounted,defineExpose} from "vue";
defineExpose({
  updateView,
});

2.引入页调用

const ModalRef= ref(null);
const ModalKey= ref(0);

 <ModalPanel  ref="ModalRef" :key="ModalKey"/>

刷新数据

  if(ModalRef.value!=null){
    ModalRef.value.updateViewList() //刷新数据
  }

更新组件

ModalKey.value+= 1;
