Element 对话框简单使用

官方文档介绍的是页内对话框，但没有基于组件的对话框，这里记录一下，原理就是父子传值是否显示

父页导入组件

<template>
    <div class="home">
        <el-button @click="btnAdd">添加用户</el-button>
        <Dialog :visible.sync="visible" title="添加用户"></Dialog>
    </div>
</template>

<script>
    import Dialog from "../components/dialog";

    export default {
        name: 'Home',
        components: {
            Dialog
        },
        data() {
            return {
                visible: false
            }
        },
        methods: {
            btnAdd() {
                this.visible = true
            }
        }
    }
</script>

对话框

<template>
    <div>
        <el-dialog
                v-bind="$attrs"
                v-on="$listeners"
                @open="onOpen"
                @close="onClose"
                :title="title"
                对话框打开后是否可以点击后边灰色区域关闭对话框
                :close-on-click-modal='false'>
            <el-row :gutter="15">
                <el-form ref="elForm" :model="formData" :rules="rules" size="medium" label-width="100px">
                    <el-col :span="23">

                        </el-form-item>
                    </el-col>
                    <el-col :span="23">
