Google Maps API 对象的使用方式如下:google.maps."Constructor" 看起来。

我想伪造下面列出的电话...

//var map = new google.maps.Map(value);
//var fireStationBound = new google.maps.LatLng(val,val);
//var bounds = new google.maps.LatLngBounds(boundary, boundary);
//var markerFireStation = new google.maps.Marker(val);
//var waterstationLayer = new google.maps.KmlLayer(val);
//map.mapTypes.set();

...使用下面的代码...

 $(document).ready(function() {

   function google() {

     /* todo: Setup for every constructor a test function returning the test data */

     function LatLng(value) {

     }

     function LatLngBounds(value,value) {

     }

     function Marker(value) {

     }

     function Map(value) {

     }

     function KmlLayer(value) {

     }

     var maps = {
                  maps: {
                          LatLng: LatLng,
                          LatLngBounds: LatLngBounds,
                          Marker: Marker,
                          Map: Map,
                          KmlLayer: KmlLayer
                        }
                };
                return maps;
     }

     **// Works**
     var google = new google();    
     var bound = new google.maps.LatLng(10);
     var bounds = new google.maps.LatLngBounds(10,20);
     var marker = new google.maps.Marker(10);
     var layer = new google.maps.KmlLayer(10);
     var map = new google.maps.Map(10);
     **// Doesn't Work **
     map.mapTypes.set();
});

我怎样才能伪造这个谷歌代码...

map.mapTypes.set();

...通过调用...返回

var map = google.maps.Map(val);

我的 JavaScript 必须是什么样子才能键入 map.mapTypes.set() 并最终调用 set 函数？

我只想伪造我在代码中用于单元测试的 Google 对象。

最佳答案

这是我们的 v3.19.18 版 Google map stub 。它最初是用 CoffeeScript 编写的，但我通过 js2coffee 运行了它这是一个原始的 Javascript 实现。我已经为您添加了 mapTypes.set()。
