Jquery returns JSON data in IE browser prompts to download the problem _javascript tips

Today encountered jquery return JSON data, ie browser prompts to download the problem, when the data submitted after the return of the original JSON data, in the fire arc test Normal, but the Internet Explorer is always prompted to save, search on the internet, most of it is said that the contenttype set to "text/ XML "I tested the bottom, the return value is undefined,

Original return value set: Context. Response.ContentType = "Application/json";

Try: Context. Response.ContentType = "text/xml;"; Failed

Then I tried it: context. Response.ContentType = "Text/plain;charset=utf-8";

Success!
