如何实现文件下载使用AJAX和MVC [英] How to implement file download with AJAX and MVC

问题描述

我想使用MVC下，jQuery的AJAX调用一些PARAMS提供文件下载操作

I would like to provide a file download operation by using the jQuery AJAX call with some params under MVC

例如

(javascript)
function DoDownload(startDate) {

  $.ajax({ 
     url:"controller/GetFile/",
     data: {startDate:startDate}
     ...
  });

}

C# Controller Code

 public void GetFile(string startDate) {

  var results = doQuearyWith(startDate);

  // Create file based on results

  ....
  // HOw do I tell the server to make this a file download??
 }

通常我只想让我的文件下载链接，如：

I typically would just make my file download a link such as:

<a h r e f="mycontroller/getfile/1"/>Download</a>

但在上述日期的情况下将是动态的。

but in the case above the date will be dynamic.

如果我不使用AJAX，这将是一个preferred方式使用JavaScript来传递在PARAMS到MVC控制器？

If I dont use ajax, what would be a preferred way to pass in the params to the MVC controller using javascript?

例如：

window.location  = "mycontroller/GetFile/" + $("#fromDate").val();

假设的日期2012年12月25日是 这会产生

assuming the date is 12-25-2012 would this produce

mycontroller/GetFile/12/25/2012

将MVC把这三个PARAMS？

would MVC treat this as three params?

推荐答案

我最后怎么了做的是从喜欢我的javascript调用我的控制器：

What I ended up doing is calling my controller from my javascript like:

VAR URL =/ myController的/的GetFile？的startDate =+ $（＃指明MyDate）。VAL（）+等等...

var url = "/mycontroller/GetFile?startDate=" + $("#mydate").val() + etc...

了window.location = URL;

window.location = url;

mycontroller.cs

mycontroller.cs

 public void GetFile(DateTime startDate) 
{

}

我最初关注的是与日期参数。我没有想得分析它。

My original concern was with the date parameters. I didnt want to have to parse it.
