Sorting a JScript Array on a String Field with leading No.s

Question

I have a JS object, with an internal array of another JS object. The internal onw is like

function outerObj()
{
    this.items = new Array();
    this.clear = function () {
        this.items = new Array();
    }
    function __item(v1, v2, v3, v4) {
        this.Val_1 = v1;
        this.Val_2 = v2;
        this.Val_3 = v3;
        this.Val_4 = v4;
    }
    this.add = function (vA, vB, vC, vD) {
        this.items.push( new __item(vA, vB, vC, vD) );
    }
    ...
}

The array is loaded through an SPServices getListItems() call, using .each( . . . ) on the resultant XML. The results are ordered (<OrderBy>), but the results are the common irritation:

1
10
11
2
21
3
42A
42B

I cannot get away from the inclusion of letters (this is the name of real-world items), while I want the sort to be

1
2
3
10
11
21
42A
42B

Suggestions?

Answer 1

Just use javascript array.sort()

code would look like this:

this.items.sort()

Answer 2

Actually, Elisha, it would look like this.

    items.sort(function (v1, v2) { 
        /* algorythm here */ 
    }); 

The algorythm is where I can add the intelligence that is aware of the fact that the array is holding objects, not values, and where i can really examine the property upon which i am sorting.

In fact, I can write an external function, and call it from the anonymous function.

Thanks Elisha; this got me on track.

I am answering here, so that I can use the ability to format the answer. But Elisha should get the credit on this one.

Incidentally, the function needs to return a negative number, zero, or a positive number. The sign of what is returned indicates the sorting order between the two arguments passed in.
