如何在页面加载上设置功能条件？

Question

我有这个控制器：

   (function () {
    "use strict";
    angular.module('damageEvent').controller("inspectionsDamageEventsController", ["siteId",                                                                         "mapguideService",
                                                                                    inspectionsDamageEventsController]);

    function inspectionsDamageEventsController(siteId, mapguideService, inspectionsDamageList) 
    {
       var self = this;
       this.siteId = siteId;
       this.mapguideService = mapguideService;
       this.isMapGuideEnabled = mapguideService.enabled;

       self.mapguideService.zoom("site", self.siteId);

    }
    })();

此行在页面加载时触发：

 self.mapguideService.zoom("site", self.siteId);

我需要根据此值在页面加载时触发上面的行：

this.isMapGuideEnabled

如果isMapGuideEnabled为真，则mapguideService.zoom（）会被触发，否则不会。

如何在页面加载时设置此条件？

if救援......

(function () {
    "use strict";
    angular.module('damageEvent').controller("inspectionsDamageEventsController", ["siteId",                                                                         "mapguideService",
                                                                                    inspectionsDamageEventsController]);

    function inspectionsDamageEventsController(siteId, mapguideService, inspectionsDamageList) 
    {
       var self = this;
       this.siteId = siteId;
       this.mapguideService = mapguideService;
       this.isMapGuideEnabled = mapguideService.enabled;

       if (this.isMapGuideEnabled) {
         self.mapguideService.zoom("site", self.siteId);
       }
    }
    })();
