Jquery returns json data and prompts for download in IE browser_javascript skills

Today I encountered a problem where Jquery returns json data, and IE browser prompts for downloading. After submitting the data, the data returned is originally json data. It is normal when tested in Fire Arc, but IE always prompts to save. I searched online. Most of them say that the ContentType is set to "text/xml". I tested it and the return value is undefined.

The original return value setting: context.Response.ContentType = "application/json";

Try: context.Response.ContentType = "text/xml;"; failed

Later tried: context.Response.ContentType = "text/plain;charset=UTF-8";

Success!
