AngularJS 和 Leaflet 地图居中绑定到 ng-repeat 迭代变量

Question

我正在尝试将传单的中心属性绑定到模型，如下所示：

<!DOCTYPE html>
<html>
<title>Test Leaflet</title>
<link rel="stylesheet" href="http://cdn.leafletjs.com/leaflet-0.7.1/leaflet.css" />
<script src="http://cdn.leafletjs.com/leaflet-0.7.1/leaflet.js"></script>
<script src="http://ajax.googleapis.com/ajax/libs/angularjs/1.2.6/angular.min.js"></script>
<script src="angular-leaflet-directive.min.js"></script>
<script src="map.js"></script>
<body ng-app="mapApp" ng-controller="mapCtrl">
<ul>
<li ng-repeat="m in maps | orderBy:'ident':false">
        <div>
        {{m.ident}}
        <leaflet center="{{m.center}}" width="300px" height="300px"></leaflet>
        </div>
</li>
</ul>
</body>
</html>

与 JavaScript:

var mapApp = angular.module('mapApp', ['leaflet-directive']);
mapApp.controller('mapCtrl', ['$scope', function($scope, $http)
{
    $scope.maps = [
        { ident: "MAP1", center: { lat: 45, lng: 90, zoom: 10 } },
        { ident: "MAP2", center: { lat: -45, lng: -90, zoom: 10 } },
        { ident: "MAP3", center: { lat: 45, lng: -90, zoom: 10 } },
        { ident: "MAP4", center: { lat: -45, lng: 90, zoom: 10 } }
      ];
}]);

但是这不起作用。只有在删除中心属性后，我才能获得地图，但它们不会居中，即：

<leaflet width="300px" height="300px"></leaflet>

任何人都可以在不完全改变整体结构的情况下协助完成这项工作。

（提前道歉：我无法让示例在 Plunker 或 Fiddle 上运行，尽管它在我所有的浏览器中都运行良好）

Answer 1

我想你有几个选择...其中一个是这个...

将此添加到您的控制器：

angular.extend($scope, {
    center: {
        lat: 51.505,
        lng: -0.09,
        zoom: 4
    }
});

您可能还需要这样做（根据 https://github.com/tombatossals/angular-leaflet-directive）：

"If you want to have more than one map on the page and access their respective map objects, add an id attribute to your leaflet directive in HTML:"

<leaflet id="mymap" lf-center="center" height="480px" width="640px"></leaflet>

让我知道你能走多远...我们将从那里开始。

Answer 2

所以我决定模拟它并测试一些东西。这对我有用...

HTML:

<ul>
<li ng-repeat="m in maps | orderBy:'ident':false">
        <div>
        {{m.ident}}
        <leaflet id="{{m.ident}}" center="m.center" width="300px" height="300px"></leaflet>
        </div>
</li>
</ul>

JS:

$scope.center = {center: { lat: 45, lng: 90, zoom: 1 }};

$scope.maps = [
    { ident: "MAP1", center: { lat: -45, lng: -90, zoom: 18 } },
    { ident: "MAP2", center: { lat: -45, lng: -90, zoom: 14} },
    { ident: "MAP3", center: { lat: -45, lng: -90, zoom: 10} },
    { ident: "MAP4", center: { lat: -45, lng: -90, zoom: 6 } }
  ];

让我知道...
