I have the following very massive array:
var arrayBig = {"count":31,"items":{"76":{"title":"office1","address":"<p><strong>London<\/strong><\/p>\r\n<p>Baker Str.<\/p>\r\n<p>Web site: <a href=\"http:\/\/example.org\">http:\/\/example.org<\/a><\/p>"},"57":{"title":....... etc. }....
And all I need is to get the first number in 'items', e.g. 76, with jQuery.
