javascript - 从我的 map 更改样式

Question

我正在学习如何使用 Ext.js 框架，并且正在使用 MVVM 模型构建简单的应用程序。我构建了一个简单的 map 并尝试对其进行服装化，我使用 Google API 和 GMapPanel 小部件创建了一个应用程序，现在我想创建一个新样式并添加它，但是我在添加我的服装样式时遇到了一些问题.

我收到以下错误:

Uncaught TypeError: Cannot read property 'set' of undefined at constructor.init (MapController.js?_dc=20151109082919:198) at new constructor (ext-all-rtl-debug.js?_dc=20151109082919:63176) at constructor [as self] (ext-all-rtl-debug.js?_dc=20151109082919:12296) at Object.widget (ext-all-rtl-debug.js?_dc=20151109082919:14662) at constructor.create (ext-all-rtl-debug.js?_dc=20151109082919:26228) at constructor.lookupComponent (ext-all-rtl-debug.js?_dc=20151109082919:123938) at constructor.prepareItems (ext-all-rtl-debug.js?_dc=20151109082919:124418) at constructor.add (ext-all-rtl-debug.js?_dc=20151109082919:123436) at constructor.initItems (ext-all-rtl-debug.js?_dc=20151109082919:123861) at constructor.initComponent (ext-all-rtl-debug.js?_dc=20151109082919:123821)

我的代码:

init: function () {

    var me = this,
        map = me.getView(), //Reference to map view
        store = map.getViewModel().getStore('Markers'), // Get the store from the ViewModel
        markers = [], // Create and empty markers array
        data;
    // Load the store
    store.load(function (records) {
        // Iterate through each record
        Ext.each(records, function (record) {
            data = record.getData(); // Get the data object from each record
            markers.push(data); // Push the objects onto the markers array
        });
    });
    map.markers = markers;  // Set the markers config for the Map component to the markers array

    var styledMapType = new google.maps.StyledMapType(

    map.mapTypes.set('styled_map', styledMapType);
    map.setMapTypeId('styled_map');

您可以简单地将样式数组添加到 gmappanel mapOptions 对象:

{
    region: 'center',
    xtype: 'gmappanel',
    gmapType: 'map',
    center: new google.maps.LatLng(53.419824, -3.0509294),
    mapOptions: {
        mapTypeId: google.maps.MapTypeId.ROADMAP,
        zoom: 15,
        styles: [
            {elementType: 'geometry', stylers: [{color: '#ebe3cd'}]},
            {elementType: 'labels.text.fill', stylers: [{color: '#523735'}]},
            {elementType: 'labels.text.stroke', stylers: [{color: '#f5f1e6'}]},
            {
                featureType: 'administrative',
