Comparing elements between two arrays in AngularJS

Question

Comparing elements between two arrays in AngularJS

I am working with two arrays, the first one looks like this:

$scope.blinkedBoxes=[3,4,1,2,..]

There will be a maximum of 8 elements in this array, each element being a number from 1 to 4.

The second array is as follows:

$scope.clickedImages=[2,4,3,1,...]

I am creating the following function:

$scope.checkCrossCorrectness = function(array1, array2){}

My goal is:

If the first element of $scope.blinkedBoxes is 2 (or any number from 1 to 4), then the first element of $scope.clickedImages cannot be 2 (or the same as the first element of the first array), it must be 1, 3, or 4. This rule applies to the subsequent elements as well (for example, if the second element in the first array is 3, then the second element in the second array can be 1, 2, or 4).

How should I go about implementing this logic?

Answer №1

Although I'm not completely certain if this is relevant to angular specifically, it seems that a basic forEach loop can be used to compare the indexes for equality.

For instance:

$scope.blinkedBoxes = [1, 2 ..] // and so on
$scope.clickedImages = [2, 1, ..] // and so forth

function functionToExecuteOnClickOrOtherAction(){
    $scope.blinkedBoxes.forEach(function(val, index){
        var isEqual = val === $scope.clickedImages[index];

        if(isEqual){
            // perform some action?
        }
    });
}
