use string variable in forEach() loop to fetch data in angular

Question

can i use string variable in angular.forEach() loop like this:

var variable= "keyname";
angular.forEach($scope.arrCategory[0].variable,function(k,d){
    //alert(k);
    angular.forEach(k,function(kk, dd){
        alert(dd);
    });
});

if it is wrong how should i use this variable in loop?

You should use bracket notation to access property by variable name:

var variable = "keyname";
angular.forEach($scope.arrCategory[0][variable], function(k,d) {
    angular.forEach(k, function(kk, dd) {
        alert(dd);
    });
});
