MVC3 导出不了文件，不知哪儿有问题
function _exportExcel() {
var postUrl = "/Resume/Export";
$.post(postUrl);
}

<a href="#" class="easyui-linkbutton" iconCls="icon-export" onclick="_exportExcel();">导出</a>

单击导出按钮，能执行到FileResult Export 为何下载不了welcome.txt文件呀？？有知道的不

C# code

                public FileResult Export()        {                    byte[] data = Encoding.UTF8.GetBytes("欢迎访问");             return File(data, "text/plain", "welcome.txt");        }

[解决办法]
AJAX无法帮你导出数据
function _exportExcel() {
var postUrl = "/Resume/Export";
location.href=postUrl;
}
