在填写表单时,我发送了closedBy
所选项目的ID
if (selectedClosedPlaces != undefined) {
place.closedBy = selectedClosedPlaces.map(function(g) {
return g._id;
});
} else {
place.closedBy = ['no_name'];
}
我使用{{place.closedBy}}在html中显示它。
我将拥有像这样的json数据
[{"_id":"56bc720bd0113ab80dd3cb2d","name":{"en":"fshu","de":"hfasj"},"closedBy":["no_name"],"category":{"_id":"56bb2999f197db040dc3b12b","name":{"en":"asdfdsf","de":"asdf"}}}},
{"_id":"56bc7238d0113ab80dd3cb2e","name":{"en":"jsfadk","de":"jkgdj"},"closedBy":["56bc720bd0113ab80dd3cb2d"],"category":{"_id":"56bb2999f197db040dc3b12b","name":{"en":"asdfdsf","de":"asdf"}}}}]
对于第一个,它将为null,所以我给了一些像['no_name']
这样的名字。添加第一个后,我可以使用selectbox选择closedBy。
现在我正在为第二个人归来。我正在使用封闭的第二个id,请检查上面的json。有了那个id,我需要获取那个特定的名字
示例:我拥有此{id} 56bc720bd0113ab80dd3cb2d
ID我需要显示name.en和name.de => fshu and hfasj
。
我正在使用服务来获取值
//此处的服务代码
.service('PlaceService', function($http) {
return {
init: function(callback) {
$http.get('/api/places').then(function(place_response) {
callback(place_response);
});
}
}
})
并在控制器中
PlaceService.init(function(place_response) {
$scope.places = place_response.data;
console.log($scope.places); //giving all the places details like the //above json.
console.log($scope.places.closedBy); // Not giving closedBy value here
任何人都可以帮助我

找到另一个第一个项,在对象数组中有特定的id,你可以使用_underscore js lib,如下所示:
var yourWantedId = ...;
var result = _.findWhere(selectedClosedPlaces, {"_id": yourWantedId });
