<script>
    $(function(){

        $('button.add').on('click',function(){
            //1. 获取图片的相关信息
            // 判断用户是否选择了图片?
            let img_url = $('#img_url').val();

                let prev = current.prev(); // 前一个元素

            });

            //删除
            remove.click(function () {
                if (confirm('确认删除吗?')) {
