从一个array1删除重复项到array2

Question

我在angularjs中有两个数组。

$scope.array1 = ["ID","Name","Brand","State"]; $scope.array2 = ["ID","Name","Brand","State","created_by","approved_by","date"];

我想要如下输出：

$scope.array3 = ["created_by","approved_by","date"];

Answer 1

使用javascript中的filter（）和include（）函数来解决您的问题

$scope.array1 = ["ID","Name","Brand","State"];
$scope.array2 = ["ID","Name","Brand","State","created_by","approved_by","date"];
$scope.array3 = array2.filter(s => !array1.includes(s));
console.log($scope.array3);

您可以尝试一下。这可能对您有用。

Answer 2

您可以使用.filter()和.includes()来过滤第二个数组：

let array1 = ["ID","Name","Brand","State"];
let array2 = ["ID","Name","Brand","State","created_by","approved_by","date"];

let result = array2.filter(s => !array1.includes(s));

console.log(result);
