public List Regions { get; set; }
在名为News.An Region Model的模型中
public class Region
{
public int Id { get; set; }
public string Name { get; set; }
public static Region Parse(DataRow row)
{
return new Region
{
Id = Database.GetInteger(row["Id"]),
Name = Database.GetString(row["Region"]),
};
}
}
在Javascript中我使用带有formdata的AJAX post方法.我想设置这个区域.
var regionList = [];
if (selected === "region") {
if (region.length <= 0) {
toastr.warning('Lütfen en az bir bölge seçin !!!');
return;
}
for (var i = 0; i < region.length; i++) {
var item = {
Id: region[i]
}
regionList.push(item);
}
console.log(regionList);
formData.append("Regions", regionList);
}
JS上面的代码我写这样来设置它
public ActionResult AddByRegion(News item)
{
int refPortal = SessionRepository.GetPortalId();
if(refPortal!=1)
return View("List", NewsRepository.ListAll(SessionRepository.GetPortalId()));
if (item == null
|| string.IsNullOrEmpty(item.Title)
|| string.IsNullOrEmpty(item.Content)
)
return Content(Serialization.JsonSerialize(new { Status = 400 }));
return Content(Serialization.JsonSerialize(new { Status = 200, Result = NewsRepository.AddByRegion(item) }));
}
上面的代码我将进入控制器.但它至少返回0记录,但至少我选择了两个区域.
$.ajax({
type: 'POST',
url: '@Url.Action("AddByRegion", "News")',
data: formData,
contentType: false,
processData: false,
success: function(data) {
var result = JSON.parse(data);
if (result.Result === "SUCCEED") {
toastr.success('@Resources.Resource.Success_MediaAdd');
window.location.reload();
return;
}
else {
toastr.error('@Resources.Resource.Error_Unexpected');
return;
}
},
error: function(error) {
toastr.error('@Resources.Resource.Error_Unexpected');
return;
},
beforeSend: function() {
waitingDialog.show('Wait...');
},
complete: function() {
waitingDialog.hide();
}
});
我的Ajax方法在上面.我哪里弄错了？
提前致谢.
解决方法:
如果您使用FormData发送数据,则需要.append()将每个单独的名称/值赋予FormData.由于它是一个集合,因此必须包含集合索引器(例如,必须为零和连续)
formData.append("Regions[0].Id", someValue);
formData.append("Regions[0].Name", someValue);
formData.append("Regions[1].Id", someValue);
formData.append("Regions[1].Name", someValue);
由于你在循环中这样做,你可以使用
for (var i = 0; i < region.length; i++) {
formData.append("Regions[" + i + "].Id", region[i])
}
