Trouble with associative array

Why wouldn't I be able to get the value of Control.subsriptions in the first case, but am in the second?

Code:

Control.subscriptions = new Array();
Control.subscriptions["abc"] = 'what?';
Control.subscriptions["Def"] = 'is next?';
alert(Control.subscriptions); //alerts blank
alert(Control.subscriptions["abc"]); //alerts "what?"

Code:

Control.subscriptions = new Array();
Control.subscriptions[0] = 'what?';
Control.subscriptions[1] = 'is next?';
alert(Control.subscriptions); //alerts "what?, is next?"
alert(Control.subscriptions[0]); //alerts "what?"

I need to be able to see them to make sure I have cleared all objects later on

I believe it is because you can't increment associative arrays. Because the values are strings instead of a numerical index. So since you didn't call a specific index or set of indeces, it doesn't know what to return.

At least that is the way I understand it... hopefully I am not way off base.

I'm thinking the same thing as you. It can't really iterate through them as it normally would. I specifically alerted every associative and got values, and then did my cleanup and saw everything turned to null. You'd think there has to be a better way though to ensure that things got cleaned properly. I'm working on an AJAX app where there's not one refresh so its important to clean the objects up.

Is there a particular reason it HAS to be associative? I think it would be much more clean to use the default array indeces. Seems to me it would be more versatile, and a lot less room for typographical errors.

Well i have it set up that the key is an ID of a DIV. It uses that to automatically build out onclicks and whatnot. I could redo that class so that i wont need that though possibly. It works fine now, so if that is the answer I have to write it down for later.

Gotcha, no reason to change it if it is working.
