Alle Popup von Ebenen bei Klick auf externen Link anzeigen und ausblenden - openlayrs3

Question

Von unten Funktion onOff: function() Ich bekomme Popup von externen Link, aber nur ein Popup. Müssen alle Popups von vecorlayer source anzeigen.

onOff: function() { 
    var abc = ConnectWebMap; 
     var vectorSource = new ol.source.Vector({ 
      projection : 'EPSG:4326', 
      format: new ol.format.GeoJSON(), 
      url: 'resources/multipoint.geojson' 
      }); 
    featureCount = [];  
     // Get the array of features 
var featureCount = vector.getSource().getFeatures(); 

// Go through this array and get coordinates of their geometry. 
featureCount.forEach(function(feature) { 
    console.log('get all features' + feature.getGeometry().getCoordinates()); 
    allpopup = []; 
    var allpopup = feature.getGeometry().getCoordinates(); 
    if (feature) { 
     popup.setPosition(allpopup); 
    content.innerHTML = feature.get('name'); 
    } 
}); 

Ich füge Marker durch GeoJSON und sie auf map.on('click', function(evt) zeigen Aber ich will alle Popup mit Button-Klick-Marker ein- und ausblenden sichtbar nur poup wird angezeigt und ausgeblendet.

Von Anker-Tag müssen alle Popups

<a id="toggle">Show/Hide</a> 

Below wechseln meine Json-Code ist

} 

Vektorebene

vector = new ol.layer.Vector({ 
    source: new ol.source.Vector({ 
    projection : 'EPSG:4326', 
    format: new ol.format.GeoJSON(), 
    url: 'resources/multipoint.geojson' 
}), 
    style: styleFunction1 
}); 

Popup-Funktion

  var element = document.getElementById('popup'); 
      var content = document.getElementById('popup-content'); 
      var closer = document.getElementById('popup-closer'); 



      var popup = new ol.Overlay({ 
       element: element, 
       positioning: 'bottom-center', 
       stopEvent: false 
      }); 
      map.addOverlay(popup); 

// display popup on click 
map.on('click', function(evt) { 
    var feature = map.forEachFeatureAtPixel(evt.pixel, function(feature, layer) { 
    return feature; 
    }, null, function(layer) { 
    return layer != circleLayer; 
    }); 

    if (feature) { 
    popup.setPosition(evt.coordinate); 
    content.innerHTML = feature.get('name'); 

    } else { 

    } 
}); 

closer.onclick = function() { 
    popup.setPosition(undefined); 
    closer.blur(); 
    return false; 
};

Zeigen alle Popup-

on: function() { 
    var abc = ConnectWebMap; 
    $('#popupGroup').html(''); 
    var vectorSource = new ol.source.Vector({ 
    projection : 'EPSG:4326', 
    format: new ol.format.GeoJSON(), 
    url: 'resources/multipoint.geojson' 
    }); 
    featureCount = [];  
     // Get the array of features 
     var featureCount = vector.getSource().getFeatures(); 

     multiPopup = 0; 
// Go through this array and get coordinates of their geometry. 
featureCount.forEach(function(feature) { 
// console.log('get all features' + feature.getGeometry().getCoordinates()); 
// multiPopup = feature.get('id'); 
allpopup = []; 
var allpopup = feature.getGeometry().getCoordinates(); 
if (feature) { 
    var popupTemplate = '<div id="popup' + multiPopup +'" class="ol-popup">'+ 
    '<a href="#" id="popup-closer' + multiPopup +'" class="ol-popup-closer"></a>'+ 
    '<div id="popup-content' + multiPopup +'"></div></div>'; 
    $('#popupGroup').append(popupTemplate); 

    var element = document.getElementById('popup' + multiPopup); 
    var content = document.getElementById('popup-content' + multiPopup); 
    var closer = document.getElementById('popup-closer' + multiPopup); 

    closer.onclick = function() { 
    popup.setPosition(undefined); 
    closer.blur(); 
    return false; 
    }; 

hide alle Popup

off: function() { 
    var abc = ConnectWebMap; 
    console.log('multiPopup' + multiPopup); 
    for(var i = 0; i<multiPopup; i++){ 
     $('#popup-closer' + i).click(); 
    }; 
    $('#popupGroup').html(''); 
} 

};
