How can I sort an array with objects in?

programming flash

I want to sort an array that contains object references.
I want to sort on one of the values held by the objects.

I have the following sample code, say:


   ActionScript:abc = new Array();
   
   abc[0] = new Object();
   abc[0].anotherObj = new Object();
   abc[0].anotherObj.myNumber = 21;
   
   abc[1] = new Object();
   abc[1].anotherObj = new Object();
   abc[1].anotherObj.myNumber = 11;
   
   abc[2] = new Object();
   abc[2].anotherObj = new Object();
   abc[2].anotherObj.myNumber = 2;
   
   abc[3] = new Object();
   abc[3].anotherObj = new Object();
   abc[3].anotherObj.myNumber = 3;
   
   abc.sortOn("anotherObj.myNumber", Array.NUMERIC);
   trace(abc[0].anotherObj.myNumber);
   trace(abc[1].anotherObj.myNumber);

In the above code… I want to sort on anotherObj.myNumber.
The above doesn’t work.
I wasn’t sure what I should put for anotherObj.myNumber??

Any help would be appreciated.

Thanks.

look up Array.sortOn and/or sort functions (for Array.sort) in Flash help :slight_smile:

Not sure this is the best way.

abc = new Array();
reOrder = function (b, a) {
var a = a.anotherObj.myNumber;
var b = b.anotherObj.myNumber;
if (a<b) {
return -1;
} else if (a>b) {
return 1;
} else {
return 0;
}
};
abc[0] = new Object();
abc[0].anotherObj = new Object();
abc[0].anotherObj.myNumber = 21;
abc[1] = new Object();
abc[1].anotherObj = new Object();
abc[1].anotherObj.myNumber = 11;
abc[2] = new Object();
abc[2].anotherObj = new Object();
abc[2].anotherObj.myNumber = 2;
abc[3] = new Object();
abc[3].anotherObj = new Object();
abc[3].anotherObj.myNumber = 3;
abc.sort(reOrder);
