我有一个视图，该视图显示了基于他们从文档中检索到的PO的行项列表。一旦视图加载了底部的行项，我在条目旁边有一个"x"按钮，但不明白如何在不重新加载页面的情况下对视图项执行操作。

本质上，当用户完成"删除"行项时，我希望它们提交，然后表单将重新组合在一起，但只是保留视图上的行。

(注意:使用filehelper来解析一个特殊分隔的文件，这就是为什么有这么多额外的运行和流和字符串。还要注意;)

Class -

namespace WebDocumentEditor
{
    public class LineItemListInfo
    {
        public string asiLineNumber { get; set; }
        public string itemSKU { get; set; }
        public string itemQTY { get; set; }
        public string itemUOM { get; set; }
        public string itemPrice { get; set; }
    }
}

控制器构建列表:

public ActionResult SearchForPODocument(string POinput)
        {
            string contents = string.Empty;
            if (POinput == "" | POinput == null)
            {
                return RedirectToAction("Index");               
            }
            LoadConfigValues();
            foreach (string file in Directory.GetFiles(exportsArchive))
            {
                using (var stream = new StreamReader(file))
                {
                    contents = stream.ReadToEnd().ToString();
                    if (contents.Contains(POinput))
                    {
                        SendPOfor850Trim(contents, POinput);
                        ViewBag.DocumentWithPO = documentWithPO;
                        SendFoundPOForASIHDRParse(documentWithPO);
                        SendFoundPOForASISTAParse(documentWithPO);
                        SendFoundPOForASILINParse(documentWithPO);
                        break;                    
                    }
                }
            }
            ViewBag.PoNotFound = "PO Not Found";
            return View();
        }

//Helper Method to break up info from ASISLIN Line
    public void SendFoundPOForASILINParse(string documentWithPO)
    {
        var engine = new FileHelperEngine<ParseASILIN>();
        var result = engine.ReadString(documentWithPO);

        foreach (ParseASILIN parse in result)
        {
            if (parse.lineID.Contains("ASILIN"))
            {
                //action on ASILIN line found
                SetupLineItemInfo(parse.asiLineNumber, parse.itemSKU, parse.itemQTY, parse.itemUOM, parse.itemPrice);
            }
            ViewBag.LineItemList = lineItemList;
        }
    }

    //This moves the parsed info into the LineItemLiftInfo class properties to be appended as a whole line
    public void SetupLineItemInfo(string asiLineNumber, string itemSKU, string itemQTY, string itemUOM, string itemPrice)
    {
        LineItemListInfo fullLineItemCombined = new LineItemListInfo();
        fullLineItemCombined.asiLineNumber = asiLineNumber;
        fullLineItemCombined.itemSKU = itemSKU;
        fullLineItemCombined.itemQTY = itemQTY;
        fullLineItemCombined.itemUOM = itemUOM;
        fullLineItemCombined.itemPrice = itemPrice;
        lineItemList.Add(fullLineItemCombined);
    }

视图:

ASILIN:

<ul id="lineItems" class="list-unstyled">
    <li>
        ASILineNumber | Item Price | Item Quantity | Item SKU | Item Unit Of Measurement
    </li>
    @foreach (var item in (List<LineItemListInfo>)ViewBag.LineItemList)
        {
        <li>
            <button type="button" id="removeLine"class="glyphicon glyphicon-remove"></button>
            @item.asiLineNumber | @item.itemPrice | @item.itemQTY | @item.itemSKU | @item.itemUOM
        </li>
    }
</ul>
