2020.7.24基于layui和tp6的上传组件，只需要一句代码就完成了上传功能。
之前也做过简单的处理，但是文章已经太古老了~现在我对这个上传做了行的疯转，添加了上传进度条，将关闭按钮定位更加准确等
下面是示意图

具体事项代码：
1：在tp的common.php中添加如下代码
```

</div>
        <script>
            layui.use(['upload','element'], function(){
                var upload = layui.upload;
                var element = layui.element;
                var url = "{$url}";
                //执行实例
                var uploadInst = upload.render({
                    elem: '#kzl_uploader{$input_name}' //绑定元素
                    ,url: url //上传接口
                    ,before: function(obj){ //obj参数包含的信息，跟 choose回调完全一致，可参见上文。
                        layer.load(); //上传loading
                    }
                    ,done: function(res){
                        //上传完毕回调
                        layer.closeAll(); //关闭loading
                        if(res.code == 1 ||res.code ==200){
                            $("#kzl_close_btn{$input_name}").css("display","block");
                            var img = res.data;
                            $("#kzl_preview_img{$input_name}").attr("src",img);
                            $("input[name={$input_name}]").val(img);
                            $("input[name={$input_name}_100]").val(res.suoluetu1);
                            layer.msg(res.msg,{icon:1});
                        }else {
                            layer.msg(res.msg,{icon:0});
                        }
                    }
                  ,progress: function(n, elem){
                    var percent = n + '%' //获取进度百分比
                    element.progress('kzl_progress_{$input_name}_demo', percent); //可配合 layui 进度条元素使用
                    
                    //以下系 layui 2.5.6 新增
                    console.log(elem); //得到当前触发的元素 DOM 对象。可通过该元素定义的属性值匹配到对应的进度条。
                  }
                    ,error: function(){
                        //请求异常回调
                        layer.closeAll(); //关闭loading
                        layer.msg("上传出错，稍后重试",{icon:0});
                    }
                });
            });
            //重新上传

```

我的上传地址是：url('Upload/upload')，代码如下【tp6】如果你的框架是tp5的需要自行修改一下

```
 public function upload(){
        // 获取表单上传文件 例如上传了001.jpg
        $file = request()->file();
        try {
            validate(['image'=>'filesize:10240|fileExt:jpg,gif,jpeg,png|image:200,200,jpg'])
                ->check($file);
            $file = request()->file("file");
            // 上传到本地服务器
            $savename = \think\facade\Filesystem::disk('upload')->putFile( 'avatar', $file);

$suoluetu1_name = $this->th($savename);

$savename = Request::domain()."/data/upload/".$savename;
            return json(["code"=>200,"msg"=>"成功","data"=>$savename,"suoluetu1"=>$suoluetu1_name]);
        } catch (think\exception\ValidateException $e) {
            return json(["code"=>40000,"msg"=>$e->getMessage()]);
        }
    }
```
