Download a file by jQuery Ajax

Question

I have a Struts2 action in the server side for file downloading.

<action name="download" class="com.xxx.DownAction">
    <result name="success" type="stream">
        <param name="contentType">text/plain</param>
        <param name="inputName">imageStream</param>
        <param name="contentDisposition">attachment;filename={fileName}</param>
        <param name="bufferSize">1024</param>
    </result>
</action>

However when I call the action using the jQuery:

$.post(
  "/download.action",{
    para1:value1,
    para2:value2
    ....
  },function(data){
      console.info(data);
   }
);

in Firebug I see the data is retrieved with the Binary stream. I wonder how to open the file downloading window with which the user can save the file locally?

Downloading files using AJAX method

1. $("#FileDownloadBtn"). click(function () {
2. event. preventDefault();
3. var rootPath = '@Url.Content("~")';
4. $. ajax({
5. type: "post",
6. url: rootpath + "/RequestFormEdit? handler=FileDownload",
7. success: function (data) {
8. }
