JS代码：
//保存
function btnAdd() {
var formData = new FormData($("#frm")[0]); $.ajax({
url: "/Admin/ContentManage/SaveEdit",
type: "POST",
data: formData,
contentType: false, //必须false才会避开jQuery对 formdata 的默认处理 XMLHttpRequest会对 formdata 进行正确的处理
processData: false, //必须false才会自动加上正确的Content-Type
success: function (data) {
if (data == "OK") {
alert("保存成功");
$.iDialog("close"); //刷新父页面
}
else {
alert("保存失败：" + data);
}
}
});
}
ASP.NET MVC后台代码：
//首先判断路径是否存在,不存在则创建路径
string path = Path.Combine(System.Configuration.ConfigurationManager.AppSettings["UploadsFiles"], folder + "/" + DateTime.Now.ToString("yyyyMMdd") + "/");
string physicalPath = server.MapPath(path);
if (!Directory.Exists(physicalPath))
{
Directory.CreateDirectory(physicalPath);
} HttpPostedFileBase file = request.Files[];
string newFileName = Guid.NewGuid().ToString().Replace("-", "") + Path.GetExtension(file.FileName);
string savePath = Path.Combine(physicalPath, newFileName);
file.SaveAs(savePath);
fileName = file.FileName;
string url = Path.Combine(path, newFileName);
return url;
