angular - 无法在 Angular/Ionic 的表单提交中显示 Google Places place_id
问题描述
我正在使用 Google 地点自动完成功能在 Ion-Searchbar 中返回一系列地点。除了自动完成的输入之外,一切都以表格形式提交,它应该是它自己的 place_id 而不是实际输入。如何在表单中提交 place_id 而不是实际输入?这是代码:
add-place.page.ts
import { Component, NgZone } from '@angular/core';
import { FormBuilder, FormGroup } from '@angular/forms';
import { PlacesService } from '../../../services/places.service';
import {} from 'googlemaps';
@Component({
selector: 'add-place',
templateUrl: './add-place.page.html',
styleUrls: ['./add-place.page.scss'],
})
export class AddPlacePage {
private formCreatePlace: FormGroup;
GoogleAutocomplete: google.maps.places.AutocompleteService;
autocomplete: any;
autocompleteItems: any[];
location: any;
placeid: any;
structuredformatting: any;
showStorage: any;
message: String;
constructor(
public zone: NgZone,
private formBuilder: FormBuilder,
private placesService: PlacesService) {
this.GoogleAutocomplete = new google.maps.places.AutocompleteService();
this.autocompleteItems = [];
this.formCreatePlace = this.formBuilder.group ({
autocomplete: [''],
type_of_activity: [''],
has_owner: [''],
deal_available: ['']
})
}
updateSearchResults(){
if (this.autocomplete == '') {
this.autocompleteItems = [];
return;
}
this.GoogleAutocomplete.getPlacePredictions({ input: this.autocomplete },
(predictions, status) => {
this.autocompleteItems = [];
this.zone.run(() => {
predictions.forEach((prediction) => {
this.autocompleteItems.push(prediction);
});
});
});
}
selectSearchResult(item) {
console.log(item)
this.location = item;
this.placeid = this.location.place_id;
console.log('Place ID '+ this.placeid)
this.autocompleteItems = [];
}
onSubmit() {
this.placesService.create(this.formCreatePlace.value);
}
}
add-place.page.html
<form [formGroup]="formCreatePlace" (ngSubmit)="onSubmit()">
<ion-grid>
<ion-row>
<ion-col size="1">
</ion-col>
<ion-col>
<ion-searchbar animated formControlName="autocomplete" (ngModelChange)="updateSearchResults()" (ionInput)="updateSearchResults()" placeholder="Search for a place"></ion-searchbar>
<ion-list [hidden]="autocompleteItems.length == 0">
<ion-item *ngFor="let item of autocompleteItems" tappable (click)="selectSearchResult(item)">
{{ item.description }}
</ion-item>
</ion-list>
</ion-col>
<ion-col size="1">
</ion-col>
</ion-row>
</ion-grid>
</ion-form>
解决方案
输入值只是用于从 google api 返回预测的原始文本,我看不到它可以携带 place_id 的方式。selectSearchResult
当用户单击这样的项目时,您应该将逻辑集中在函数上:
selectSearchResult(item) {
console.log(item)
this.location = item;
this.placeid = this.location.place_id;
console.log('Place ID '+ this.placeid)
this.autocompleteItems = [];
//adjust this part with the object you are expecting
this.placesService.create(this.placeid);
}
