给定下面的最小示例，两张地图最终位于不同的位置；出于某种原因，尽管坐标是瑞典斯德哥尔摩，但后者最终还是在法国。

我该如何解决这个奇怪的问题？

要重现，只需将以下内容复制到 html 文件中并在浏览器中运行它（jsFiddle 和 Plunkr 都不想显示地图......）：

<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">
<body ng-app="app">

    <div ng-controller="ctrl">
        <map center="59.325, 18.07" zoom="7"></map>
        <map center="map.center" zoom="7"></map>
    </div>

    <script src="../../../Scripts/angular.js"></script>
    <script src="http://maps.google.com/maps/api/js"></script>
    <script src="../../../Scripts/ng-map.js"></script>
    <script type="text/javascript">
        var app = angular.module('app', ['ngMap']);

        app.controller('ctrl', ['$scope',
            function ($scope) {
                $scope.map = {
                    center: [59.325, 18.07]
                }
            }
        ]);
    </script>
</body>
</html>

这是因为它使用谷歌地图初始化指令的方式

您的文本“59.325, 18.07”已加载到 html 上，这意味着在指令上编译它已经存在的值，否则，将对象 map.center 以它创建的指令的方式传递它不会获得值，架构应该是重构只是为了从对象中获取你的价值，当我创建自己的地图指令时，我发现了这些不同

这是我的指令的一部分：

mapModule.directive("map", ['$timeout', function ($timeout) {
   return {

     scaleControl: "@",
     show: "="
  },
  compile: function (tElem, tAttrs) {
     return {
        pre: function (scope, element, attrs, ctrl) {
           var toResize, toCenter;
           var map;
           var currentMarkers;

           var el = document.createElement("div");
           el.style.width = "100%";
           if (scope.height) {
              el.style.height = scope.height;
           }
           else {
              el.style.height = "450px";
           }
           element.prepend(el);

           carregaMapa();

           // update the control
           function carregaMapa() {
