Getting the value of an object's property where the key is a blank string
javascript, javascript-objects, properties
Solution
If you're trying to get the value of the property whose key is an empty string, then you can do
var value = myObject[''];
If you try to get the "first property" of an object, you can't because properties in javascript objects aren't ordered.
Problem
Given this object: ``` : http://www.w3.org/2005/Atom gd: http://schemas.google.com/g/2005 openSearch: http://a9.com/-/spec/opensearch/1.1/ app: http://www.w3.org/2007/app; media: http://search.yahoo.com/mrss/ ``` How do I get the value of the first property? I suspect this is an easy process, but I'm drawing a blank. Thanks in advance. The object is built as such: Server side (php): ``` $namespaces = $feedXML->getNamespaces(true); $arr = array( 'Status' => 'Success', 'Message' => 'Feed fetched.', 'Namespaces' => $namespaces, 'Feed XML' => $feedXML ); echo json_encode($arr); ``` Client side (JS): ``` var output = ''; for (property in dataj["Namespaces"]) { output += property + ': ' + dataj["Namespaces"][property] + '; '; } alert(output); ``` I would like to be able to check the namespaces to see if this is Atom or RDF. It sounds like just iterating each property is going to be the best way.
