How to convert Array 2D to Array collection in Flex

i have 2d array follows:

asia  india  chennai  tn  category1 product1 100 asia  india  mumbai   mh  category1 product1 100 asia  india  calcutta ct  category1 product1 100 asia  india  calcutta ct  category2 product2 200 emea  uk     london   ln  category3 product1 123     emea  uk     london   ln  category3 product2 455     emea  uk     reading  rn  category1 product1 500     emea  uk     reading  rn  category1 product2 430

how can convert above 2d array array collection i  can access each data individual attribute first column to  indicate attribute "continent",2nd column "country" etc .,  arraycollection haveing structure {continent:"asia",  country:"india",...etc} , on.how achieve dynamically.

hi rohini_1327,

 

your question not clear. since refer 2d array, take mean have array of arrays, such that:

 

myarray:array = [("asia", "india", "chennai", "tn", "category1", "product1", 100),

     ("asia", "india", "mumbai", "mh", "category1", "product1", 100),

     ("asia", "india", "calcutta", "ct", "category1", "product1", 100),

     ("asia", "india", "calcutta", "ct", "category2", "product2", 200),

     ("emea", "uk", "london", "ln", "category3", "product1", 123),

     ("emea", "uk", "london", "ln", "category3", "product2", 455),

     ("emea", "uk", "reading", "rn", "category1", "product1", 500),

     ("emea", "uk", "reading", "rn", "category1", "product2", 430)];

 

 

 

if so, since know category names , nice , neat:

 

 

var types:array = ["continent", "country", "city", "abbr", "cat1", "prod1", "qty"];  // array of names columns

 

var myarraycollection:arraycollection = new arraycollection;

 

for each(var arr:array in myarray)    //  iterate through each elment of 2d array

{

       var temp:object = new object;  // temporary holder our arraycollection items

      for(var i:int = 0; < 7; i++)          //  iterate through  each sub-array

      {

             temp[types(i)] = arr(i);        

       }                                                    

       myarraycollection.additem(temp);

}

 

 

now:  myarraycollection[0].continent = "asia"

 

or:  var obj:object = myarraycollection.getitemat(3);

obj.city = "calcutta"

 

       

you have iterate through list. in case, 2d array, have 2 nested iterations. if each array element of myarray array, add iteration function.
