I'm getting an XML error messages for JSON?

UPDATE 2:

I did not mention that I do not get the error below in Chromium, but I do get it in IE8.

UPDATE 1:

ORIGINAL QUESTION:

I have a serverside page which generates json data, which works perfectly well when accessed by jquery. However, when i navigate to the webpage which actually generates the json data, I get the following clientside error message in the browser:

The XML page cannot be displayed 
Cannot view XML input using style sheet. Please correct the error and then click the Refresh button, or try again later. 


--------------------------------------------------------------------------------

Invalid at the top level of the document. Error processing resource 'http://companyname.com/json/data.aspx?id=7

[{"key":7,"value":"Default"}]

Why does that happen and how can I stop the error message fro开发者_JAVA百科m appearing?

Same problem here, context.Response.ContentType="text/plain"; made my day...

The error appears, because the JSON data is probably served as type text/xml and your browser tries to interpret the output as XML. If you served it as application/json that would probably not happen. Why would you want to directly access the page though?

Two tips here: 1) Install HttpFox Addon in Firefox which allows you to see exactly what is being sent/received 2) Install JSON View in Firefox which allows you to view JSON response in the browser.
