c#给html传参数,c# - 通过Html.ActionLink将输入参数传递给控制器​​方法 - 堆栈内存溢出...

当用户单击Html.ActionLink ，我需要调用一个控制器方法，该方法将为该用户下载csv报告。 我还需要将此控制器中两个输入框的值传递给该控制器，以表示它们要查找的开始和结束日期范围。

目前，我可以使用jQuery分配Html.ActionLink参数，但是它们没有将其返回给控制器。 控制器方法中的两个参数都用null值实例化。

我也不能使用表单/提交方法，因为已经在此特定表单上使用了该方法，以允许用户在导出到csv之前查看请求的日期范围内的数据。

jQuery的

$(document).ready(function() {

$('#startDate').change(function () {

$('a').attr('start', $(this).val());

});

$('#endDate').change(function () {

$('a').attr('end', $(this).val());

});

});

ASP MVC 3视图

@using (Html.BeginForm())

{

@Html.TextBox("startDate", ViewBag.StartDate as string, new { placeholder = " Start Date" })

@Html.TextBox("endDate", ViewBag.EndDate as string, new { placeholder = " End Date" })

@Html.ActionLink("Export to Spreadsheet", "ExportToCsv", new { start = "" , end = ""} )

@ViewBag.ErrorMessage

}

控制器方式

public void ExportToCsv(string start, string end)

{

var grid = new System.Web.UI.WebControls.GridView();

var banks = (from b in db.AgentTransmission

where b.RecordStatus.Equals("C") &&

b.WelcomeLetter

select b)

.AsEnumerable()

.Select(x => new

{

LastName = x.LastName,

FirstName = x.FirstName,

MiddleInitial = x.MiddleInitial,

EffectiveDate = x.EffectiveDate,

Status = x.displayStatus,

Email = x.Email,

Address1 = x.LocationStreet1,

Address2 = x.LocationStreet2,

City = x.LocationCity,

State = x.LocationState,

Zip = "'" + x.LocationZip,

CreatedOn = x.CreatedDate

});

grid.DataSource = banks.ToList();

grid.DataBind();

string style = @" ";

Response.ClearContent();

Response.AddHeader("content-disposition", "attachment; filename=WelcomeLetterOutput.xls");

Response.ContentType = "application/excel";

StringWriter sw = new StringWriter();

HtmlTextWriter htw = new HtmlTextWriter(sw);

grid.RenderControl(htw);

Response.Write(style);

Response.Write(sw.ToString());

Response.End();

}
