Empty JSON respone

[alexpts@…]

Sorry my bad English.

If ajax respone is empty, then

541 string - parseJSON()

return window.JSON.parse( data )

SyntaxError: JSON.parse: unexpected end of data (Firefox 19.0.2)

This has nothing to do with jQuery. An empty string is not valid JSON, hence the error.

#14533 is a duplicate of this ticket.

Whilst it's not valid JSON, it's incredibly dense to leave this as it is. It should just fall back to not parsing the response instead of failing completely.

BTW- if you want to leave in the utterly daft behaviour then at *least* add in some way of informing the user of your silly decisions via some exception or whatever.

Open the browser's console. There will be a message there.

Would be nice if JSON.parse("") didn't throw an exception, as when using $.ajax() together with ASP.NET MVC, it is common practice to use 'void' as return type on simple POSTs, which returns an empty string.
