1.4.4 - jQuery.parseJSON(string_with_only_whitespaces like ' ') throws an exception

[christiaan.vandenpoel@…]

I don't know whether this is expected behavior but jQuery 1.4.4 raises an exception when you try jQuery.parseJSON with a string which contains onyl whitespaces.

This occurs for example when you do a Ajax request (dataType: 'json') and the server returns just a string with one or more whitespaces.

I'm using Chrome 7.0.517.44 on ubuntu/linux so it uses the native parser (window.JSON.parse() )

Well just whitespace isn't a valid JSON response AFAIK

[dmethvin]

​http://json.org/ indicates the minimal valid json is '{}'.

quite right, I'm taking this to the rails team, as this came up when using rails with ajax and json requests.

Thx for your help.
