Question

如何在angularJS中从2个不同的字符串和数字数组创建对象数组？例如：

$scope.array1=['sale1','sale2','sale3']
$scope.array2=[2,3,4]

从这两个数组我希望将一个数组作为

$scope.resultArray=[
                    {'key':'sale1','value':2},
                    {'key':'sale2','value':3},
                    {'key':'sale3','value':4}
                  ]

Answer 1

您可以执行以下操作：

for (var i = 0; i < $scope.array1.length; i++) {
   $scope.resultArray.push({
     'key': $scope.array1[i],
     'value': $scope.array2[i]
   });
 }

代码段正在运作：

(function() {
  'use strict';
  
  angular.module('app', [])
    .controller('mainCtrl', function($scope) {
      $scope.array1 = ['sale1', 'sale2', 'sale3'];
      $scope.array2 = [2, 3, 4];
      $scope.resultArray = [];

      for (var i = 0; i < $scope.array1.length; i++) {
        $scope.resultArray.push({
          'key': $scope.array1[i],
          'value': $scope.array2[i]
        });
      }
    });
})();

<body ng-controller="mainCtrl">
  <div ng-repeat="obj in resultArray track by $index">
    <span ng-bind="obj.key + ' - ' + obj.value"></span>
  </div>
</body>

</html>

Answer 2

使用下划线zip

$scope.array1=['sale1','sale2','sale3']
$scope.array2=[2,3,4]
$scope.resultArray = _.zip($scope.array1, $scope.array2)

Answer 3

for(var i=0;$scope.array1.length>i;i++){
     $scope.resultArray.push({$scope.array1[i]:$scope.array2[i]});

}
