Question

我有一个带有datetime字段和status（on / off）字段的表单，我将它们组合在一个json对象{"time":"2002-03-01T03:01:00.000Z","status":"off"}中 onclick添加按钮，我需要将此对象添加到json数组结果应该是这样的：

[{"time":"2002-03-01T03:01:00.000Z","status":"off"},
{"time":"2002-03-01T03:01:00.000Z","status":"on"},
{"time":"2002-03-01T03:01:00.000Z","status":"off"},
{"time":"2002-03-01T03:01:00.000Z","status":"on"}]

在每个按钮单击中将对象添加到数组中

Answer 1

您对它的外观不太清楚，但是您只需要在控制器中的某个位置插入array.push(object)，就可以通过ng-click在某个按钮上调用它。

这是一个演示：

var app = angular.module('myApp', []);
app.controller('myCtrl', function($scope) {
  $scope.array = [{
      "time": "2002-03-01T03:01:00.000Z",
      "status": "off"
    },
    {
      "time": "2002-03-01T03:01:00.000Z",
      "status": "on"
    },
    {
      "time": "2002-03-01T03:01:00.000Z",
      "status": "off"
    },
    {
      "time": "2002-03-01T03:01:00.000Z",
      "status": "on"
    }
  ];

  $scope.add = function(object) {
    $scope.array.push(object);
    $scope.st = null; // reset
  }
});

  <div ng-app="myApp" ng-controller="myCtrl">

    Time: <input ng-model="tm" type="datetime-local" /><br>
    Status: <select ng-model="st" ng-options="x for x in ['on','off']"></select><br>
    <button ng-click="add({'time':tm,'status':st || 'off'})">Add</button>
    
    <hr>
    <div ng-repeat="obj in array">
      Time: {{obj.time | date}}, status: {{obj.status}}
    </div>
    <hr>
    <pre>{{array | json}}</pre>

  </div>
</body>

</html>

Answer 2

您可以这样做

<input type="text" ng-model="$scope.jsonStyleObject"> 

<button ng-model="$scope.jsonStyleObject"ng-click="addItemFunction($scope.jsonStyleObject)">Add to array of 
objects</button>

在视图中使用ng-click可以在控制器中调用一个函数（我的首选方法是使用“ vm。”，但也可以使用“ $ scope”）。

创建json数组并在angularjs中单击按钮时向其添加对象
