RE: [flexcoders] Associative Arrays / "Hashes"

[Erik Westra]

So if I understand it correctly u have a series of events. If u would
convert this xml to and object u would have something like this:

event[0].month = "04";
event[0].day = "14";
event[0].short = "heckey";
event[0].description = "bla";


Now u want to get access to all events on a certain day in a certain
month like this

myObject["04"]["14"][0].short = "hockey";
myObject["04"]["14"][0].description = "bla";


In order to be able to do that u need to convert your initial data, u
can do that like this:

/*
input:
        
        events_array
                        [0]
                                month
                                day
                                short
                                description
                        [1]
                                ...

output:

        object
                [month_str]
                        [day_str]
                                [0]
                                        short
                                        description
                                [1]
                                        ...
                        [day_str]
                                ...
                [month_str]     
                        ...

                                        
*/
public function convertData(events_array:Array):Object
{
        var obj:Object = new Object();
        var length_num:Number = events_array.length;
        while (length_num--)
        {
                var currentEvent_obj:Object = events_array[length_num];
                var month_str:String = currentEvent_obj.month;
                var day_str:String = currentEvent_obj.day;
        
                var month_obj:Object = obj[month_str];
                if (!month_obj)
                {
                                month_obj = myObject_obj[month_str] =
new Object();
                };
        
                var day_array:Array = month_obj[day_str];
                if (!day_array)
                        {
                        day_array = month_obj[day_str] = new Array();
                };
        
                day_array.push({short: currentEvent_obj.short, 
                                    description:
currentEvent_obj.description});
        };
        return obj;
};

Subject: [flexcoders] Associative Arrays / "Hashes"



I am trying to see if I can get an array to be more like a hash...

what i mean is say I have the following:

<node>
<events>
  <month>04</month>
  <day>14</day>
  <short>hockey</short>
  <description>blah</description>
</events>
<events>
  <month>04</month>
  <day>14</day>
  <short>reading</short>
  <description>blah</description>
</events>
<events>
  <month>04</month>
  <day>14</day>
  <short>baseball</short>
  <description>blah</description>
</events>
<node>

I want to loop through that and produce something like this...

myObject[<month>][<day>]=Array(of Objects for that day);

so I could just do a myObject[<month>][<day>] and get back an array of
objects of those events.

First, does this make sense and two how would I do this in AS?

Thanks,
Michael
