这是首页，引用组件，组件见附件

<template>  
    <view style="background-color: aqua;">  

        <scroll-refresh-floor :refreshBackgroundImage='img'>  
            <view >下拉进入二楼</view>  
        </scroll-refresh-floor>  
    </view>  
</template>  

<script>  
    import scrollRefreshFloor from '../../components/scroll-refresh-floor.vue'  
    export default {  
        data() {  
            return {  
                img:"https://img2.baidu.com/it/u=921884047,4195025824&fm=253&fmt=auto&app=138&f=JPEG?w=560&h=300"  
            };  
        },  
        components: {  
            scrollRefreshFloor  
        },  
        methods: {  

        }  
    };  
</script>
