Jquery文件下载（$ .fileDownload） [英] Jquery File download ($.fileDownload)

问题描述

我正在使用jquery文件下载..

I am using jquery file download ..

代码如下：

 function downloadFile(){
var downloadOptions = {
preparingMessageHtml: "We are preparing your report, please wait...",
failMessageHtml: "No reports generated. No Survey data is available."
                  };

     $.fileDownload("displaySurveyReport.action",downloadOptions);
return false; 
}

这是我正在按钮点击

当我点击按钮，prepareMessageHtml：我们正在准备你的报告，请稍候...，显示在一个对话框...
问题是，这个对话框在完成准备之后不会关闭，我必须手动关闭...
如何让它关闭，当文件完成准备并准备下载..

When i click on the button , the preparingMessageHtml: "We are preparing your report, please wait...", is shown in a dialog box ... The problem is that this dialog box does not go off after the fle completes its preparing and i have to close it manually ... How can i make it go off when the file completes its preparation and is ready to download..

谢谢

推荐答案

p>为了使JQuery知道文件下载，您的响应头必须包含 Set-Cookie：fileDownload = true;路径= / 。

In order to make JQuery knows the file download just ocurred, your response header must contains Set-Cookie: fileDownload=true; path=/.

在Java中：

response.setHeader("Set-Cookie", "fileDownload=true; path=/");
