[英]How merge two objects array in angularjs?
I want to append following object array with existing one in angulajs for implementing load more feature. 我想在angulajs中追加跟随对象数组和现有的对象数组,以实现更多的加载功能。
ie,appending AJAX response with existing one each time. 即,每次附加现有的AJAX响应。
I have one variable, $scope.actions
which contains following JSON
data, 我有一个变量,
$scope.actions
包含以下JSON
数据,
{
"total": 13,
"per_page": 2,
"current_page": 1,
"last_page": 7,
"next_page_url": "http://invoice.local/activities/?page=2",
"prev_page_url": null,
"from": 1,
"to": 2,
"data": [
{
"id": 2108,
"action_type_id": 202,
"user_id": 1
},
{
"id": 2108,
"action_type_id": 202,
"user_id": 1
}
]
}
I want to append following JSON
response each time this variable. 我想在每次这个变量时追加
JSON
响应。
{
"data": [
{
"id": 2108,
"action_type_id": 202,
"user_id": 1
},
{
"id": 2108,
"action_type_id": 202,
"user_id": 1
}
]
}
I have tried with $scope.actions.data.concat(data.data);
我试过
$scope.actions.data.concat(data.data);
but it is not working and getting following error message 但它无法正常工作并收到以下错误消息
$scope.actions.data.concat is not a function
You can use angular.extend(dest, src1, src2,...);
你可以使用
angular.extend(dest, src1, src2,...);
In your case it would be : 在你的情况下,它将是:
angular.extend($scope.actions.data, data);
See documentation here : 请参阅此处的文档
https://docs.angularjs.org/api/ng/function/angular.extend https://docs.angularjs.org/api/ng/function/angular.extend
Otherwise, if you only get new values from the server, you can do the following 否则,如果只从服务器获取新值,则可以执行以下操作
for (var i=0; i<data.length; i++){
$scope.actions.data.push(data[i]);
}
This works for me : 这对我有用:
$scope.array1 = $scope.array1.concat(array2)
In your case it would be : 在你的情况下,它将是:
$scope.actions.data = $scope.actions.data.concat(data)
$scope.actions.data.concat is not a function
同样的问题,但我解决了这个问题
$scope.actions.data = [].concat($scope.actions.data , data)
Simple 简单
var a=[{a:4}], b=[{b:5}]
angular.merge(a,b) // [{a:4, b:5}]
Tested on angular 1.4.1 测试角度为1.4.1
