我正在使用knockoutjs呈現項目的集合。在允許用戶進行一些內聯編輯之後,我需要將集合發回服務器。但是,該集合沒有在服務器上填充,因爲我沒有使用name =「[0] .Blah」命名約定。有誰知道如何使用knockoutjs渲染名稱屬性,或者如何創建一個模型綁定器,這將允許我從ValueProvider中提取值?knockoutjs與mvc集合模型綁定
您可以在下面的調試過程中看到ValueProvider的屏幕截圖。
這裏是我的管理視圖模型:
public class FundLevelInvestmentUploadResult
{
public string FileName { get; set; }
public IList<FundLevelInvestmentViewModel> Items { get; set; }
public int NumberOfErrors { get; set; }
public bool ShowErrorsOnly { get; set; }
public FundLevelInvestmentUploadResult()
{
Items = new List<FundLevelInvestmentViewModel>();
}
}
下面是 「項目」 的管理類:
public class FundLevelInvestmentViewModel
{
private string _fund;
private string _fundType;
private string _date;
private string _netOfWaivedFees;
private string _waivedFees;
private string _bcip;
private string _fxRate;
public uint RowIndex { get; set; }
public int? DealCode { get; set; }
public bool DealCodeIsValid { get; set; }
public string Fund
{
get { return _fund; }
set { _fund = GetString(value); }
}
public bool FundIsValid { get; set; }
public string FundType
{
get { return _fundType; }
set { _fundType = GetString(value); }
}
public bool FundTypeIsValid { get; set; }
public string DateOfInvestment
{
get { return _date; }
set { _date = GetString(value); }
}
public bool DateOfInvestmentIsValid { get; set; }
public string NetOfWaivedFees
{
get { return _netOfWaivedFees; }
set { _netOfWaivedFees = GetString(value); }
}
public bool NetOfWaivedFeesIsValid { get; set; }
public string WaivedFee
{
get { return _waivedFees; }
set { _waivedFees = GetString(value); }
}
public bool WaivedFeeIsValid { get; set; }
public string BCIP
{
get { return _bcip; }
set { _bcip = GetString(value); }
}
public bool BCIPIsValid { get; set; }
public string ExchangeRateToUSD
{
get { return _fxRate; }
set { _fxRate = GetString(value); }
}
public bool ExchangeRateToUSDIsValid { get; set; }
public string FileName { get; set; }
private IList<string> _errors;
public IList<string> Errors
{
get { return _errors ?? (_errors = new List<string>());}
set { _errors = value; }
}
public bool Show { get; set; }
public FundLevelInvestmentViewModel()
{
Errors = new List<string>();
Show = true;
}
// knockoutjs is returning "null" instead of "" for a null object when calling ko.mapping.fromJS
private string GetString(string value)
{
if (value == "null")
return string.Empty;
return value;
}
}
這裏是我的淘汰賽視圖模型:
var viewModel = {
FileData: ko.observableArray([]),
validateFile: function (file, event) {
$.ajax({
type: 'post',
url: newUrl,
data: ko.mapping.toJS(file)
}).done(function (data) {
var newFile = ko.mapping.fromJS(data);
var index = file.Items.indexOf(file);
viewModel.FileData.replace(file, newFile);
});
}
};
如果使用'toJSON'發送回服務器,它應該可以工作。你可以發佈你的模型? – Tyrsius
我添加了代碼@Tyrsius。 – devlife
你嘗試過發佈'file.FileData'嗎? – Tyrsius
