**这样一个效果**
![](https://img.tnblog.net/arcimg/aojiancc2/a37b559d85bb4557862ff11ac5a309ed.png)

**主要分为三块：**
- 一块是：一个简单的可以拖动的右下角悬浮菜单组件封装，点击它弹出这个弹窗
- 一块是：对于这个弹窗的自定义样式，主要是header和body和footer插槽的使用，也是封装的一个组件
- 一块是：最下面关于图片上传的组件封装，还有就是图片预览的组件的使用


### 可以拖动的悬浮菜单部分代码如下：
是触发的第一个组件。部分代码如下，详细的可以参考下方连接

<template>
    <div>
        
        <div class="realTranslationInfos" v-drag>
            <div class="RealtranslationBox">
                <img draggable="false" @click="openFeedbackDialog()" src="@/assets/imgs/labroom/feedback.png" alt=""
                    width="66px" height="66px">
            </div>
        </div>
        

        
        <FeedbackDialog ref="feedbackDialog" />
    </div>
</template>
<script>
import FeedbackDialog from '@/pages/feedback/feedbackDialog.vue'
export default {
    // 组件名字
    name: 'FeedBack',
    components: {
        FeedbackDialog
    },
    // 组件参数
    props: {
        id: {
            type: String,
            default: ''
        },
        index: {
            type: Number,
            default: 0
        },
    },
    data() {
        return {
            // 用来给自己封装的弹窗组件传递参数
            dialogVisible: false
        }
    },
    mounted() {
    },
    // 组件方法
    methods: {
        openFeedbackDialog() {
            //调用子组件的方法打开弹窗
            this.$refs.feedbackDialog.openFeedbackDialog();
        }
    }
}
</script>
<style scoped="scoped" lang="scss">
.realTranslationInfos {
    width: 66px;
    height: 66px;
    // background: red;
    position: fixed;
    // position: absolute;
    bottom: 56px;
    right: 20px;

    // bottom: 122px;
    // right: -30px;
    .translationContent {
        min-height: 100px;
        line-height: 23px;
        width: 338px;
        padding: 18px 74px 19px 19px;
        background: #004CB3;
        opacity: 0.80;
        border-radius: 12px;
        color: #fff;
        position: fixed;
        // position: absolute;
        right: 58px;
        bottom: 22px;
        z-index: 99999;
    }

    .RealtranslationBox {
        display: flex;
        align-items: center;
        position: absolute;
        right: 2px;
        bottom: 5px;
        z-index: 99999;

        img {
            cursor: pointer;
        }
    }
}
</style>
```
详细的使用可以参考：https://www.tnblog.net/aojiancc2/article/details/7829

#### 这里打开子组件弹窗的方式是调用子组件的方法打开的弹窗
```
openFeedbackDialog() {
  //调用子组件的方法打开弹窗
  this.$refs.feedbackDialog.openFeedbackDialog();
}
```
vue3中父组件调用子组件方法有点不一样了，参考：https://www.tnblog.net/xiuxin/article/details/8153


### 第二块：关于弹窗的自定义样式
