我想顯示一個項目列表,這些項目是通過帶有* ngFor的Angular 2(特別是Ionic 2)中的Google Geocoder收到的。Angular 2 - 推送到數組時顯示的錯誤* ngFor
地址modal.html
<ion-content class="address-modal">
<ion-searchbar id="pac" [(ngModel)]="searchQuery" (input)="getItems($event)"></ion-searchbar>
<ion-list>
<ion-item *ngFor="#address of addresses">
{{ address }}
</ion-item>
</ion-list>
</ion-content>
地址modal.ts
import {Page, NavController, ViewController} from 'ionic-angular';
import {ViewChild} from 'angular2/core';
declare var google: any;
@Page({
templateUrl: 'build/pages/address-modal/address-modal.html',
})
export class AddressModal {
searchQuery: string = '';
geocoder: any;
addresses: any = [];
constructor(public nav: NavController, public view: ViewController) {
this.geocoder = new google.maps.Geocoder();
}
getItems(searchbar) {
this.geocoder.geocode({ 'address': searchbar.value }, function (results, status) {
if (status == google.maps.GeocoderStatus.OK) {
console.log('len ' + results.length);
console.log(results);
for(var i = 0; i < results.length; i++) {
this.addresses.push(results.formatted_address);
}
} else {
console.error("Geocode was not successful for the following reason: " + status);
}
});
}
成功地址解析器返回與結果的列表,這是我顯示在控制檯,但鉻立即塊執行,並顯示以下錯誤:
address-modal.ts:45 Uncaught TypeError: Cannot read property 'addresses' of undefined
指向行
this.addresses.push(results.formatted_address);
我想顯示在我的* ngFor我的模板塊formatted_addresses名單。 (我不希望使用谷歌的搜索框自動完成)
