Question

i want to create a function that compares 2 arrays and returns indexes of items found. if for examples my arrays are:

var distances:Array = new Array (0,275,217,385,275,0,251);
var selectedDist:Array = new Array (217,275,251);

i would like it to return 2,4,6

Answer 1

Try the following:

var indices:Array = [];

for each(var distance:int in selectedDist) {
    var index:int = distances.indexOf(distance);
    if (index >= 0) {
        indices.push(index);
    }
}

return indices;
