Question

我试图从我的html代码中获取数据，如“acquringCode”，“cardAcceptor”和“merchantId”。我无法想象如何在我的控制器中获取该数据。我知道它的request.form。我相信我做错了。有没有更简单的方法让我通过函数传递对象或每个名称作为参数？

HTML

<script type="text/javascript">
$(document).ready(function () {
    $("#SavetreventLocationLookupAddButton").click(function () {
        $("#addSaveTreventLocationLookup").submit();
    });
});

        </tr>

            </td>
        </tr>
         <tr>
            <td colspan="2" class="label">Merchant Id:</td>

            AdminProductionServices.TreventLocationLookup treventLocationLookup = Administrator.Models.AdminProduction.TreventLocationLookup.loadTreventLocationLookup(Guid.Empty, Guid.Empty, string.Empty, string.Empty, string.Empty)[0];

            treventLocationLookup.acquiringInstitutionIdentifcationCode = acquiringInstitutionIdentificationCode;
            treventLocationLookup.cardAcceptorIdentificationCode = cardAcceptorIdentificationCode;
            treventLocationLookup.merchantId = merchantId;
            Administrator.Models.AdminProduction.TreventLocationLookup.addTreventLocationLookup(treventLocationLookup);

Answer 1

创建一个像这样的viewModel：

public class TreventLocationLookupViewModel
{
    public string InstitutionIdentificationCode {get; set;}
    public string CardAcceptorIdentificationCode {get; set;}
    public string MerchantId {get; set;}
}

然后在你的Action中使用它：

public ActionResult AddSaveTreventLocationLookup(TreventLocationLookupViewModel model)
{

        AdminProductionServices.TreventLocationLookup treventLocationLookup = Administrator.Models.AdminProduction.TreventLocationLookup.loadTreventLocationLookup(Guid.Empty, Guid.Empty, string.Empty, string.Empty, string.Empty)[0];

        treventLocationLookup.acquiringInstitutionIdentifcationCode = model.InstitutionIdentificationCode;
        treventLocationLookup.cardAcceptorIdentificationCode = model.CardAcceptorIdentificationCode;
        treventLocationLookup.merchantId = model.MerchantId;

        Administrator.Models.AdminProduction.TreventLocationLookup.addTreventLocationLookup(treventLocationLookup);

    return RedirectToAction("SearchTreventLocationLookup", "Prod");
}

MVC将负责将请求值绑定到模型。无论如何，您应该阅读有关模型绑定器和验证的内容，以获得一个想法。

Answer 2

请尝试将FormCollection参数添加到操作AddSaveTreventLocationLookup

像这样：

public ActionResult AddSaveTreventLocationLookup(FormCollection formCollection)
{

// now you can get the values you want
     string acquiringInstitutionIdentificationCode = formCollection["AcquiringInstitutionIdentificationCode"];
.......

Answer 3

veblock的回答是完全正确的。但您也可以绑定到操作中的简单变量。

public ActionResult AddSaveTreventLocationLookup(string InstitutionIdentificationCode, string CardAcceptorIdentificationCode, string MerchantId)
    {
     ..code..
    }

只要您的表单字段与变量命名相同，MVC将在查找request.form，request.querystring和路由变量中的可能源之后为您绑定它们。

如何使用method =“post”从表单中获取数据？如何在我的控制器中请求数据？
