使用了这两个插件
lazy-load-img
vue-lazy-load-img
当有新数据替换掉原有的goodsList后，懒加载的图片不变，不知道怎么处理

<p v-for="item in goodsList">
    <vue-lazy-load-img 
        mode="diy" 
        :time="50" 
        :complete="true" 
        :position="{ top: 0, right: 0, bottom: 0, left: 0 }" 
        :diy="{ backgroundSize: 'cover', backgroundRepeat: 'no-repeat', backgroundPosition: 'center center' }"
        @before="before" 
        @success="success" 
        @error="error">
        <img 
            :src="'../image/load-img.png'" 
            :src="item.thumb_img">
    </vue-lazy-load-img>
</p>
                        
<script src="../script/lazy-load-img.js"></script>
<script src="../script/vue-lazy-load-img.js"></script>

data: {
    goodsList: []
}
