js代码 -----url指向你的后台上传操作

//多图片上传
upload.render({
    elem: '#multiple_img_upload'
    ,url: '/admin/Goods/upload'
    ,multiple: true
    ,before: function(obj){
        //预读本地文件示例，不支持ie8
        obj.preview(function(index, file, result){
            $('#div-slide_show').append('<img src="'+ result +'" alt="'+ file.name
                +'" title="点击删除" class="layui-upload-img">')
        });
    }
    ,done: function(res){
        //如果上传成功
        if (res.status == 1) {
            //追加图片成功追加文件名至图片容器
            multiple_images.push(res.data.url);
            $('.multiple_show_img').val(multiple_images);
            layer.msg(res.msg);
        }else {
            //提示信息
            dialog.tip(res.message);
        }
    }
});

核心js ------type:代表可以上传的图片后缀名也可以加gif

var n = wk.uploads({num:3,type:'jpg,png',url:"{:url('admin/upload/upload')}"});
function imgDel(e,obj){
    wk.uploads_del(e,obj,n,"{:url('admin/upload/deleteLocality')}");
}
