循环遍历对象数组以查找是否有一个值不同

Question

我有一个对象数组，并且想知道其中一个对象的值是否与其余值不同。

$scope.myArray = [{name:'ted', age:'18', gender: 'm'}, 
        {name:'bob', age:'18', gender: 'm'}, 
        {name:'ben', age:'19', gender: 'm'} 
]; 

现在我遍历他们...

angular.forEach($scope.myArray, function(value, key) { 
    console.log(value.age); 
    //logs 18, 18, 19 
    //how to I evaluate if one of the ages is different? 
}); 

Answer 1

你可以做somethng这样

angular.forEach($scope.myArray, function(value, key) { 
    if ($scope.myArray[0].age != value.age){ 
     $scope.isDifferent = true; 
     return false;   
    }   
});
