How to work with object, if I want...
var object = { 'title': value };
alert( object[ /* Whatever */ ] ); // Should return 'title' NOT value
Thanks.

@All OP confirmed in a comment on a now-deleted answer that he/she really wants the string "title" -- the name of the property.T.J. Crowder– T.J. Crowder2010-11-26 11:33:22 +00:00Commented Nov 26, 2010 at 11:33

This question is similar to: How do I loop through or enumerate a JavaScript object?. If you believe it’s different, please edit the question, make it clear how it’s different and/or how the answers on that question are not helpful for your problem.dumbass– dumbass2024-12-21 08:50:06 +00:00Commented Dec 21, 2024 at 8:50

Use a for...in loop to enumerate an object's keys, like this:
for(var key in object) {
alert(key); //to get the key's value, use object[key]
}
To be safe, in case someone messed with the object prototype, use .hasOwnProperty() like this:
for(var key in object) {
if(object.hasOwnProperty(key)) {
alert(key);
}
}

hasOwnProperty. :-) And possibly ECMAScript 5's Object.keys.

@Marry - you're kind :) there are lots of brilliant people here, many much smarter than I...and some of the top JavaScript guys aren't here at all ;)
