1.解决使用dialog的什么问题？

1.解决引入Dialog去定义一个visible变量

2.减少一些重复的dom，比如每个dialog都带有的确定和取消

3.统一去配置elementPlus的Dialog的api

2.基于 el-dialog 进行初步封装

<template>
  <div class="spurs-dialog">
    <el-dialog
        v-bind="$attrs"
        v-model="dialogVisible"
        :append-to-body="true"
        :close-on-click-modal="false"
        :close-on-press-escape="false"
        draggable
        >
      <slot name="body"></slot>
      <template #footer>
      <span class="dialog-footer">
        <el-button @click="dialogVisible=false">取消</el-button>
        <el-button  v-if="dialogType!='readonlyDialog'" type="primary" @click="saveSubmit">
          确 定
        </el-button>
      </span>
      </template>
      <slot name="footer"></slot>
    </el-dialog>
  </div>
</template>
<script setup lang="ts">
import {ref} from "vue";
let dialogVisible = ref(false)
defineExpose({
  dialogVisible
})
const props = defineProps({
  dialogType: {type:String, default:""}//默认有确定和取消readonlyDialog展示dialog只有取消
});
const close = () =>{
  dialogVisible.value = false
}
const emit = defineEmits(['saveSubmit'])
const saveSubmit = () => {
  emit('saveSubmit');
}
</script>

1.首先用v-bind="$attrs"去接收elementPlus 所有父组件使用的 api等

2.用defineExpose把控制显示隐藏的dialogVisible暴露出去，让父组件去控制

3.定义dialog的类型 默认都有 确定和取消按钮 但是有的dialog只有展示功能 定义readonlyDialog的时候只有取消按钮，然后定义一个footer的插槽来定义特殊的情况

4.通过defineEmits 定义确定按钮saveSubmit事件，让父组件去接收

使用

<template>
  <div class="simple-dialog">
    <el-button @click="spursDialogRef.dialogVisible = true">打开dialog</el-button>
    <spurs-dialog
        ref="spursDialogRef"
        :title="title"
        @saveSubmit="saveSubmit"
    >
      <template #body>
        <span>我是dialog111</span>
      </template>
      <template #footer>
        <el-button type="success" @click="spursDialogRef.dialogVisible = true">我是操作2</el-button>
      </template>
    </spurs-dialog>
  </div>
</template>
<script setup lang="ts">
import SpursDialog from '@/components/SpursDialog/index.vue'
import {ref} from "vue";
let title = ref('提示')
const spursDialogRef = ref <any> ()
const saveSubmit = () => {
  console.log("点击了确定按钮")
}
</script>

3.一个页面多个dialog的情况

定义不同的ref

<template>
  <div class="simple-dialog">
    <el-button @click="spursDialogRef.dialogVisible = true">打开dialog</el-button>
    <el-button @click="spursDialogRef2.dialogVisible = true">打开dialog2</el-button>
    <spurs-dialog
        ref="spursDialogRef"
        :title="title"
        @saveSubmit="saveSubmit"
    >
      <template #body>
        <span>我是dialog111</span>
      </template>
      <template #footer>
        <el-button type="success" @click="spursDialogRef.dialogVisible = true">我是操作2</el-button>
      </template>
    </spurs-dialog>
    <spurs-dialog
        ref="spursDialogRef2"
        :title="title"
        :dialogType="dialogType"
    >
      <template #body>
        <span>我是dialog2222</span>
      </template>
    </spurs-dialog>

  </div>
</template>
<script setup lang="ts">
import SpursDialog from '@/components/SpursDialog/index.vue'
import {ref} from "vue";
let dialogType = ref('readonlyDialog')
let title = ref('提示')
const spursDialogRef = ref <any> ()
const spursDialogRef2 = ref <any> ()
const saveSubmit = () => {
  console.log("点击了确定按钮")
}
</script>

4 嵌套的对话框

<template>
  <div class="simple-dialog">
    <el-button @click="spursDialogRef.dialogVisible = true">打开dialog</el-button>

    <spurs-dialog
        ref="spursDialogRef"
        :title="title"
        width="900"
        @saveSubmit="saveSubmit"
    >
      <template #body>
        <span>我是dialog111</span>
        <br>
        <el-button @click="spursDialogRef2.dialogVisible = true">打开内层 Dialog</el-button>
        <spurs-dialog
            ref="spursDialogRef2"
            :title="title"
            @saveSubmit="saveSubmitInner"
        >
          <template #body>
            <span>我是内层 Dialog222222222</span>
          </template>
        </spurs-dialog>
      </template>
      <template #footer>
        <el-button type="success" @click="spursDialogRef.dialogVisible = true">我是操作2</el-button>
      </template>
    </spurs-dialog>


  </div>
</template>
<script setup lang="ts">
import SpursDialog from '@/components/SpursDialog/index.vue'
import {ref} from "vue";
let dialogType = ref('readonlyDialog')
let title = ref('提示')
const spursDialogRef = ref <any> ()
const spursDialogRef2 = ref <any> ()
const saveSubmit = () => {
  console.log("点击了确定按钮")
}
const saveSubmitInner = () => {
  console.log("点击了内层确定按钮")
}
</script>

5.全局使用dialog

最后在main.ts文件进行注册即可使用

import SpursDialog from '@/components/SpursDialog/index.vue'//引入dialog组件
app.component('SpursDialog', SpursDialog)//注册dialog
