使用vant组件中的图片上传功能，删除不完善，如何自己定义vant中图片上传功能的删除功能；

1、html模板文件：

.upfile-img .weui-uploader__files{margin-left: .1rem;float: left;}
.upfile-img .weui-uploader__input-box{margin-left: .1rem;margin-right: 0;}
.show-img .van-doc-demo-block__title{padding: .05rem .15rem .15rem;}
.show-img .applay-uploadimg .weui-uploader__file{width: .95rem;height: .95rem;}
.showImgs .van-popup{background-color:rgba(0,0,0,0); max-width: 100%;}
