IE + jQuery.Form +多部分+ JSON响应= IE浏览器尝试下载响应 [英] IE + jQuery.Form + multipart + json response = ie tries to download response

问题描述

我试图用它通过jQuery.Form插件一个文件字段提交一个表单，这里的code：

I'm trying to submit a form with a file field in it via jQuery.Form plugin, here's the code:

$('form').ajaxSubmit({
  url: "/path",
  dataType: "json",
  contentType: "multipart/form-data"
...

，服务器然后返回JSON作为响应。除了IE浏览器，它试图下载响应，文件中的所有浏览器的伟大工程。如果我从表格中删除文件领域，它也工作得很好。

The server then returns json as a response. Works great in all browsers except IE, which tries to download the response as a file. If I remove the file field from the form, it also works just fine.

我在这里，并在谷歌看到的各种解决方案，基本上试图描述，包括设置加密类型为通过jQuery的形式几乎是万能的，但没有奏效。

I've seen various solutions here and in Google and basically tried almost everything described, including setting enctype for the form via jQuery, but it didn't work.

任何建议将非常欢迎。

推荐答案

我还没有找到一个直接的解决办法，但我最终还是采取了以下措施：我用数据类型：文本我在阿贾克斯的设置，然后从控制器返回的明文，分离与值; 和解析他们在客户端。这样，IE和Forefox不再试图下载一个响应。

I have not found a direct solution to this, but I eventually implemented the following workaround: I used dataType: "text" in my ajax settings and then returned plaintext from controller, separating values with ; and parsing them on the client side. That way IE and Forefox stopped trying to download a response.

我没有发现任何其他方式prevent所述行为等，然后返回明文。我试图返回JSON作为明文，然后用$ .parseJSON解析它，但它并没有因为一些JS错误工作。

I did not find any other way to prevent said behavior other then to return plaintext. I tried returning JSON as plaintext and then parsing it with $.parseJSON, but it didn't work due to some js errors.
