问题描述
我想在选择孩子时捕捉父母的姓名和身份证.
I wants to catch parent name and id on child selection.
输出应为:
$scope.selected = [{"name": "Request1", "id":1,
"status":[{"name":"status1","isSelected":true},
{"name":"status2","isSelected":false}]
}]
能够选择孩子，但各自的父母没有.
Able to get selected child but respective parent not getting.
// Code goes here
var app = angular.module('demo', []);
app.controller('myController', function($scope){
$scope.requests=[{"name": "Request1", "id":1},
{"name": "Request2", "id":2},{"name": "Request3", "id":3}
];
$scope.statusList =[{ "name": "status1", "isSelected": true },
{ "name": "status2", "isSelected": false }
]
function initializeRequestStatus() {
angular.forEach($scope.requests, request => {
request.statusList = angular.copy($scope.statusList);
})
};
initializeRequestStatus();
});

推荐答案
您可以利用$ index获取父级名称和ID.
You can utilize the $index for getting the parent name and id.
// Code goes here
var app = angular.module('demo', []);
app.controller('myController', function($scope){
var result = [];
$scope.requests=[{"name": "Request1", "id":1},
{"name": "Request2", "id":2},{"name": "Request3", "id":3}
];
$scope.statusList =[{ "name": "status1", "isSelected": true },
{ "name": "status2", "isSelected": false }
];
$scope.getParent = function(index, selectedState){
result = [];
var req = {
"name": $scope.requests[index].name,
"id": $scope.requests[index].id,
"status": selectedState
}
result.push(req);
console.log("result",result);
return angular.toJson(result);
};
function initializeRequestStatus() {
angular.forEach($scope.requests, request => {
request.statusList = angular.copy($scope.statusList);
})
};
initializeRequestStatus();
});

<select class="form-control" ng-click="getParent($index, request.selectedStatus)" ng-options="status as status.name for status in request.statusList" ng-model="request.selectedStatus" multiple></select>
</li>
</ul>
<ul>
