C#后端接收代码
HttpFileCollection hfc = System.Web.HttpContext.Current.Request.Files;string str1 = AppDomain.CurrentDomain.SetupInformation.ApplicationBase;string imgPath = "";string fileName = "";fileName = hfc[0].FileName;imgPath = Server.MapPath("~/bin/" + fileName);imgPath = Server.MapPath("~/bin/" + modelId + "/" + productid + "/" + nodeid + "/" + filetype + "/" + fileName);hfc[0].SaveAs(imgPath);return Content(new AjaxResult { Status = ResultType.success, Message = "执行成功" }.ToJson());
具体使用过程中需要注意的是
auto: false
bindAction: ‘#testListAction’
这两个参数主要是设定为当你选择文件时不上传文件,而指定某个按钮来执行上传的动作
假设需要选择文件时则执行上传动作,只需要把auto设为true,并且去掉bindAction这个参数
其它参数可参照layui官网文档
上传文件需要判断的很多,只是简单记录个例子方便自己以后的使用。
