如何将一个值从表单传递给Ajax.ActionLink作为参数来调用一个函数

Question

我是Asp.net的新手，遇到了问题，这是我的代码： 这是我的表格：

我想将表单的SectionName字段作为参数传递给Controller的方法。

<div class="row">
<div class="col-sm-3">
    @Html.LabelFor(m => m.SectionName)
    @Html.DropDownListFor(model => model.SectionName, new SelectList(" "), "--Select Section--", new { @class = "form-control" })

</div>
<div class="col-sm-3">
    <div class="editor-lable">@Html.LabelFor(m => m.Date)</div>
    <div class="editor-field">@Html.EditorFor(m => m.Date)</div>
</div>
@*<div class="col-sm-3">
        <div class="editor-lable">@Html.LabelFor(m => m.AllPresent)</div>
        <div class="checkbox">@Html.EditorFor(m => m.AllPresent)</div>
    </div>*@
<div class="row">
    <div class="col-md-10">
        <input type="submit" id="onClick" value="Submit" class="btn btn-primary" />
    </div>
</div>

@foreach (var item in Attendances)
{

    @Ajax.ActionLink(item.SectionName, "AttendanceDetail", "Faculty", new { sectionName = Model.SectionName },
                        new AjaxOptions() { UpdateTargetId = "p1" })

}

</div>

这是我的控制器方法：

[HttpGet]
public ActionResult AttendanceDetail(GetStudentAttendance_Result model, string sectionName)
{
    GetStudentAttendance_Result at = new GetStudentAttendance_Result() {
        AttendanceDetail = model.AttendanceDetail,
        Name = model.Name,
        RollNo = model.RollNo,
        Present = model.Present,
        StudentId = model.StudentId,
        AttendanceId = model.AttendanceId
    };

    if (sectionName == null) {
        return View(at);
    } else {
        var atten = Db.GetStudentAttendance(sectionName);
        return PartialView("AttendanceDetail", atten);
    }
}

请帮我这样做！ 谢谢！
