How to append to a json object in angular js

问题:

I am having an object like this $scope.releases = [{name : "All Stage",active:true}];

I need to append more data to it

[
  {name : "Development",active:false},
  {name : "Production",active:false},
  {name : "Staging",active:false}
]

So the final data should be like this

[
   {name : "All Stage",active:true}
   {name : "Development",active:false},
   {name : "Production",active:false},
   {name : "Staging",active:false}
]

I tried the following code. But it is not appending.

app.controller('MainCtrl', function($scope) {
  // I am having an object like this
  $scope.releases = [{name : "All Stage",active:true}];
  // I need to appned some more data to it
  $scope.releases = [
    {name : "Development",active:false},
    {name : "Production",active:false},
    {name : "Staging",active:false}
  ]
});

回答1:

  $scope.releases = [{name : "All Stage",active:true}];
  // Concatenate the new array onto the original
  $scope.releases = $scope.releases.concat([
    {name : "Development",active:false},
    {name : "Production",active:false},
    {name : "Staging",active:false}
  ]);

回答2:

Just use the Array concat method

$scope.release = [{name : "All Stage",active:true}];
$scope.releases = [
    {name : "Development",active:false},
    {name : "Production",active:false},
    {name : "Staging",active:false}
];
$scope.releases = $scope.releases.concat($scope.release);
