json xhr响应打开一个下载文件弹出窗口
问题描述：
对于我们的一个ajax请求（使用.json响应），我们的一些客户端抱怨他们看到一个文件下载提示，要求用户下载.json响应。我很为难，因为考虑到这是一个xhr的回应，这绝对不会发生。有没有人看到这个？
For one of our ajax request (with a .json response) some of our clients have complained that they are seeing a "File Download" prompt asking the user to download the .json response. I am baffled because considering that this is an xhr response, this should never happen. Has anyone seen this?
谢谢

使用ASP MVC并且具有与IE相同的问题，在返回您的响应时使用此功能：
For people who are using ASP MVC and have the same problem with IE, use this when returning your response:
return Json(result, "text/plain");
编辑：标准类型是：application / json，但不适用于IE。使用text / html是危险的。
the standard type is: "application/json", but does not work with IE. using text/html is dangerous.
