Wie erstellt man ein Array von Objekten aus einer $ .each-Schleife in jquery

Question

Hie, ich versuche, ein Geojson-Objekt aus einem Array von Objekten zu erstellen. Ich verwende einen $.each() durch das Array zu durchlaufen und zu versuchen, eine Anordnung des Objekts zurückzukehren i kendofeatures genannt (a GeoJSON Objekt) so etwas wie dieses:

kendofeatures.type = "Feature"; 
    kendofeatures.properties = { 
     "id": _id, 
     "Id": _id, 
     "FaultType": _faulttype, 
     "EntryGUID": _entryguid, 
     "Date": _datcaptured, 
     "Status": _status, 
     "Area": _area, 
     "Zone": _zones, 
     "Latitude": _latutude, 
     "Longitude": _longitude, 
     "Comments": _comments, 
     "User": _fullname, 
     "UserID": _idnumber, 
     "UserPhone": _phonenumber, 
     "UserMail": _email 
    }; 
    kendofeatures.geometry = { 
     "type": "Point", 
     "coordinates": [ 
      _latutude, 
      _longitude 
     ] 
    }; 

der Code ich etwas bin mit sieht wie folgt aus:

function displayFilterResults() { 
var kendofeatures = {}; 
var dataSource = $("#grid").data("kendoGrid").dataSource; 
console.log(dataSource); 
// TODO:Gets the filter from the dataSource 
var filters = dataSource.filter(); 
console.log(filters); 
// TODO:Gets the full set of data from the data source 
var allData = dataSource.data(); 
console.log(allData); 
// TODO:Applies the filter to the data 
var query = new kendo.data.Query(allData); 
console.log(query); 
var filteredData = query.filter(filters).data; 
console.log(filteredData); 
var geoJsonObject = { 
    "type": "FeatureCollection", 
    "features": [] 
}; 
$(filteredData).each(function (index, item) { 

    var _area = item.Area; 
    var _email = item.C_Email; 
    var _fullname = item.C_FullName; 
    var _idnumber = item.C_IDNumber; 
    var _phonenumber = item.C_MobileNumber; 
    var _comments = item.Comments; 
    var _datcaptured = item.DateTimeCaptured; 
    var _faulttype = item.FaultType; 
    var _id = item.Id; 
    var _entryguid = item.RecordID; 
    var _reportedvia = item.ReportedVia; 
    var _status = item.Responce; 
    var _latutude = item.XCoordinate; 
    var _longitude = item.YCoordinate; 
    var _zones = item.Zone; 

    kendofeatures.type = "Feature"; 
    kendofeatures.properties = { 
     "id": _id, 
     "Id": _id, 
     "FaultType": _faulttype, 
     "EntryGUID": _entryguid, 
     "Date": _datcaptured, 
     "Status": _status, 
     "Area": _area, 
     "Zone": _zones, 
     "Latitude": _latutude, 
     "Longitude": _longitude, 
     "Comments": _comments, 
     "User": _fullname, 
     "UserID": _idnumber, 
     "UserPhone": _phonenumber, 
     "UserMail": _email 
    }; 
    kendofeatures.geometry = { 
     "type": "Point", 
     "coordinates": [ 
      _latutude, 
      _longitude 
     ] 
    }; 
    console.log(kendofeatures); 
    geoJsonObject.features.push(kendofeatures); 

}); 
console.log(geoJsonObject); 

}

anstelle eines Arrays mit unterschiedlichen Eigenschaften in Objekten filteredData, featureCollection wird in einer Anordnung von dem gleichen Objekt mit den gleichen Eigenschaften ergibt, Geometrie usw. Meine Frage ist, wie ich die gewünschte featureCollection zurückgeben kann. so dass meine geoJsonObject kann etwas wie folgt aussehen:

{ 
"type": "FeatureCollection", 
"features": [ 
    { 
     "type": "Feature", 
     "properties": { 
      "id": 1, 
      "Id": 1, 
      "FaultType": "Sewer Burst", 
      "EntryGUID": "0ectey-yu78ee7e-01", 
      "Date": "2016/04/01", 
      "Status": "Assigned", 
      "Area": "Senga", 
      "Zone": "Residential", 
      "geometry": { 
       "type": "Point", 
       "coordinates": [ 
     24.960937499999996, 
     11.178401873711785 
    ] 
      } 
     }, 
     { 
      "type": "Feature", 
      "properties": {}, 
      "geometry": { 
       "type": "Point", 
       "coordinates": [ 
     30.585937499999996, 
     -19.642587534013032 
    ] 
      } 
     }, 
     { 
      "type": "Feature", 
      "properties": { 
       "id": 2, 
       "Id": 2, 
       "FaultType": "Water Burst", 
       "EntryGUID": "0ectey-yu78yre7e-01", 
       "Date": "2016/02/01", 
       "Status": "Closed", 
       "Area": "CBD", 
       "Zone": "CBD", 
      }, 
      "geometry": { 
       "type": "Point", 
       "coordinates": [ 
     24.43359375, 
     -9.535748998133627 
    ] 
      } 
     }, 
     { 
      "type": "Feature", 
      "properties": { 
       "id": 3, 
       "Id": 3, 
       "FaultType": "Pot Hole", 
       "EntryGUID": "07yye54y-yu78ee7e-01", 
       "Date": "2016/03/21", 
       "Status": "Unassigned", 
       "Area": "Riverside", 
       "Zone": "Residential", 
      }, 
      "geometry": { 
       "type": "Point", 
       "coordinates": [ 
     45.439453125, 
     -17.476432197195518 
    ] 
      } 
     } 
     ] 
} 

filteredData wie folgt aussieht:

Answer 1

Verschieben featureCollection = []; außerhalb der jeder Schleife. Sie möchten mit einem leeren Array vor der Schleife beginnen und dann während einer Iteration ein Objekt auf dieses Array schieben.

var featureCollection = []; 

$(filteredData).each(function(index, item) { 
    var kendofeatures = {}; 
    // ... 
    featureCollection.push(kendofeatures); 
}); 

var geoJsonObject = { 
    "type": "FeatureCollection", 
    "features": featureCollection 
}; 

Oder Ihre geoJsonObject zunächst definieren, und dass direkt in der Schleife verwenden:

var geoJsonObject = { 
    "type": "FeatureCollection", 
    "features": [] 
}; 

$(filteredData).each(function(index, item) { 
    var kendofeatures = {}; 
    // ... 
    geoJsonObject.features.push(kendofeatures); 
});
