Javascript 模态中的谷歌地图只显示第一张地图

我试图使用GoogleMapsAPI显示我从一组json数据传入的地址的映射，但是当我运行代码时，它只显示传入的第一个地址。当模式打开时，它会显示地图，但一旦关闭并打开另一个模式，它就不会显示地图，只是一个空白

模态控制器

.controller('ModalCtrl', function($scope, $ionicModal) {
  $ionicModal.fromTemplateUrl('templates/modal.html', {
    scope: $scope,
    animation: 'slide-in-up'
  }).then(function(modal) {
    $scope.modal = modal;
  });
  $scope.openModal = function(b,c) {
    $scope.modal.show();
    var myLatlng = new google.maps.LatLng(b,c);
  var mapProp = {
    center: myLatlng,
    zoom:15,
    mapTypeId:google.maps.MapTypeId.ROADMAP
  };
  var map=new google.maps.Map(document.getElementById("map"),mapProp);

    var marker = new google.maps.Marker({
        position: myLatlng,
        map: map
    });
    $scope.map = map;

  };
  $scope.closeModal = function() {
    $scope.modal.hide();
  };
  //Cleanup the modal when we're done with it!
  $scope.$on('$destroy', function() {
    $scope.modal.remove();
  });
  // Execute action on hide modal
  $scope.$on('modal.hidden', function() {
    // Execute action
  });
  // Execute action on remove modal
  $scope.$on('modal.removed', function() {
    // Execute action
  });

})

可以从中打开模式的页面

以下是一个在模式中使用的Ionic应用程序示例：

在模式模板中有映射指令（ui-gmap-google-map、ui-gmap-marker、ui-gmap-marker）：
