tsファイルのローカルストレージエラー。無効な文字を言っている端末

Question

TSファイルでローカルストレージvaribalesを設定したり取得したりするのに問題はありませんが、私のコードの各場所でローカルストレージを呼び出しているので、端末が "Invalid Character"エラー。

import { Component } from '@angular/core'; 
import { LoadingController, ModalController, NavController, PopoverController } from 'ionic-angular'; 
import { getPostsService } from '../../services/getPosts.service'; 
import { changeDefaultCity } from '../../services/changeDefaultCity.service'; 



@Component({ 
    selector: 'page-home', 
    templateUrl: 'home.html', 
    providers: [getPostsService, changeDefaultCity]

export class Home { 

    listOfEvents: Array<any> = []; 
    selectedCity: string;

         if(!this.defaultCity){ 

           this.showCitySelector(); 

           } else { 
//default city already set so grab it from local storage 


/*THIS IS WHERE THE TERMINAL HAS A PROBLEM*/ 

      this.defaultCity = localStorage.getItem(“DefaultCity”); 

          //call service, get posts for this city 
            this.getPostSrvc.getPosts(this.defaultCity, 
           function getPostsSuccess (listOfEventsObject) { 
            for (var i in listOfEventsObject) {

/* when new city selected from list call showCitySelector */

     //ChangeCityFunction is the callback function for the popOver that shows the list of cities. 

       let changeCityFunction = function (changedNewCity) { 

              citySelectorPopOver.dismiss(); 

           //make sure no default city set 

              if(!that.defaultCity){ 

//TERMINAL GIVING SAME INVALID CHARACTER ERROR HERE 
         localStorage.setItem("DefaultCity", changedNewCity); 



              } 
              that.selectedCity = changedNewCity; 
              that.listOfEvents = []; 

           // call service again here. Same code from above    


       }; // end changeCityFunction 


     let citySelectorPopOver = 
        this.popoverCtrl.create(
         CitySelector, 
         { 
          callbackFunction: changeCityFunction 
         }); 
     citySelectorPopOver.present(); 

    } // end showCitySelector 

Answer 1

this.defaultCity = localStorage.getItem(“DefaultCity”); 

その行で引用符、“”は奇妙に見えますが、通常の引用符、""または''にそれらを変更してみてください。
