How to download a file by jQuery Ajax

0 votes

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?

Hello @kartik,

You don't need to do this through Ajax. Just use

window.location="download.action?para1=value1...."

Hope it helps!!

Thank You!!
