MVC將json編碼爲DataTables

Question

使用以下代碼填充數據以使用Ajax填充DataTable。

我的問題是，當我將公司名稱保存到數據庫時，我使用了AllowHtml（需要）。

所以我的問題是： 我如何在圖像編碼標題= asset.CompanyName這樣的數據表沒有得到腳本/ HTML什麼樣的？

// GET: Jsons/Customers 
    public JsonResult Customers([ModelBinder(typeof(DataTablesBinder))] IDataTablesRequest requestModel) 
    { 

     Db db = new Db(); 

     IQueryable<CustomersDTO> query = db.Customers.Where(x => x.CompanyId == companyId); 

     var totalCount = query.Count(); 

     #region Filtering 
     // Apply filters for searching 
     if (requestModel.Search.Value != string.Empty) 
     { 
      var value = requestModel.Search.Value.Trim(); 

      query = query.Where(p => p.Id.ToString().Contains(value.ToString()) || 
            p.CompanyName.Contains(value) 

           ); 
     } 

     var filteredCount = query.Count(); 

     #endregion Filtering 

     #region Sorting 
     // Sorting 
     var sortedColumns = requestModel.Columns.GetSortedColumns(); 
     var orderByString = String.Empty; 

     foreach (var column in sortedColumns) 
     { 
      orderByString += orderByString != String.Empty ? "," : ""; 
      orderByString += (column.Data) + (column.SortDirection == Column.OrderDirection.Ascendant ? " asc" : " desc"); 
     } 

     query = query.OrderBy(orderByString == string.Empty ? "Id asc" : orderByString); 

     #endregion Sorting 

     // Paging 
     query = query.Skip(requestModel.Start).Take(requestModel.Length); 


     var data = query.Select(asset => new 
     { 

      Id = asset.Id, 
      //Allowing HTML for CompanyName 
      Title = asset.CompanyName, 
      Zip = asset.Zip, 
      City = asset.City, 
      Active = asset.Active 

     }).ToList(); 

     return Json(new DataTablesResponse(requestModel.Draw,data, filteredCount, totalCount), JsonRequestBehavior.AllowGet); 
    }

Answer 1

的問題是你是不是HTML編碼data.Title。

return '<a href="' + someUrl + '" class="openEditor">' + htmlEncode(data.Title) + '</a>'; 

您需要建立自己的htmlEncode實現，或者使用this one：

return '<a href="' + someUrl + '" class="openEditor">' + data.Title + '</a>'; 

應替換。
