.net - 将输入参数传递给 ActionResult MVC 4

Question

我有以下.cshtml

    <fieldset>
      <legend></legend>
      <p>
        @using (Html.BeginForm("PlayerList", "Players", new{id = "Id"}, FormMethod.Post))
        {
            @Html.DropDownListFor(Model => Model.Teams, new SelectList(Enumerable.Empty<SelectListItem>(), "Id", "Name"),
               "Select a Team", new { id = "ddlTeams" }) <input type="submit" value="Get Player List" />
        }
      </p>
    </fieldset>

DropDownList 由一些 javascript 填充:

$("#ddlComps").change(function () {
        var compid = $(this).val();
        $.getJSON("../Players/LoadTeamsByCompId", { compid: compid },
                     function (teamsData) {
                        var select = $("#ddlTeams");
                        select.empty();
                        select.append($('<option/>', {
                            value: 0,
                            text: "Select a Team"
                        }));
                        $.each(teamsData, function (index, itemData) {
                            select.append($('<option/>', {
                                value: itemData.Value,
                                text: itemData.Text
                            }));
                        });
                     });
    });

为什么当我点击提交按钮时，没有 Id 参数传递给 ActionResult PlayerList？

Answer 1

在您的 DropDownList 上指定一个名称参数，指示该值用于“ID”参数。 name="id"应该可以解决。
