javascript - 如何获取for循环 Angular js中的所有值

Question

当我发出警报时，我只得到 i 的最后一个值。找不到我哪里出错了

  $scope.addToList = function (products,qty) {
    if ($scope.order.length > 0) {
        for (var i = 0; i < $scope.order.length; i++) {
            $scope.Thx=$scope.order[i].id;
            }}};

   alert($scope.Thx);

Answer 1

首先将 $scope.Thx 声明为数组。

$scope.Thx = [];

$scope.addToList = function (products, qty) {
    if ($scope.order.length > 0) {
        for (var i = 0; i < $scope.order.length; i++) {
            $scope.Thx.push($scope.order[i].id);
        }
    }
};
