javascript - 从基于 typescript 的 Angular Controller 调用 GoogleMap MarkerClusterer 方法

Question

我已经开始在我的项目中研究 TypeScript 方法，目前有点困惑如何正确组织对 MarkerClusterer 方法的调用。我目前必须对引用进行类型定义:

///<reference path="../../typings/angularjs/angular.d.ts" /> 
///<reference path="../../typings/google.maps.d.ts" /> 

但是对于 MarkerClusterer js，我无法找到定义 ts 库。我的代码现在看起来是这样的:

class paspController {

public map: any;
public markers;
public mapTab: boolean;
public currentId: number;

//Some code

showTab(tabIndex: number) {
    if (tabIndex == 2) {
        this.mapTab = true;
        var that = this;
        setTimeout(function () {
            this.options = {
                zoom: 2,
                center: new google.maps.LatLng(1, 1),
                mapTypeId: google.maps.MapTypeId.ROADMAP
            };
            if (!that.map) {
                that.map = new google.maps.Map(document.getElementById('map'), this.options);
            }
            jQuery.ajax({
                type: "GET",
                url: 'GetDivesWithCoordinates/' + that.currentId,
                success: function (data) {                      
                    that.markers = [];
                    var marker;                       
                    for (var i = 0; i < data.length; i++) {
                        marker = new google.maps.Marker({ map: that.map, draggable: false, title: data[i].Location + ": " + data[i].DiveComment, position: new google.maps.LatLng(data[i].CoordinateX, data[i].CoordinateY) });
                        that.markers.push(marker);
                    }
                   // THIS IS MY PROBLEM => var markerCluster = new MarkerClusterer(that.map, markers);
                },
                error: function (e) {
                },
                async: false
            });
        }, 100);           
    }
}

我应该如何正确调用 MarkerClusterer，或者我应该将它放在 Controller 逻辑之外？

Answer 1

THIS IS MY PROBLEM => var markerCluster = new MarkerClusterer(that.map, markers);

声明它:

declare var MarkerClusterer:any;

typescript 不会再提示了。
