Title: compare two arrays
Hi..
Let say..
array1 = [1,2,3,4,5];
array2 = [2,4];
I want to remove the elements that exists in both arrays.
So to achieve..
array3 = [1,3,5];

you can run for loop on small array to see if its elements exist in the big array . The existing element can be removed using array.splice(startIndex,count); method

private function compareArray():void{
var array1:Array = new Array(1,2,3,4,5);
var array2:Array = new Array(2,4);
for(var i:int;i<array2.length;i++){
for(var a:int;a<array1.length;a++){
if(array2[i]== array1[a]){
array1.splice(a,a+1);
}
}
}
trace(array1)
}

Sorry here is a fix .
private function compareArray():void{
var array1:Array = new Array(1,2,3,4,5);
var array2:Array = new Array(2,4);
for(var i:int=0;i<array2.length;i++){
for(var a:int=0;a<array1.length;a++){
if(array2[i]== array1[a]){
array1.splice(a,1);
}
}
}
trace(array1)
}
