很抱歉,这很简单,但无法弄清楚……
此代码为name.component.ts
import { Component, OnInit } from '@angular/core';
import {Stores} from '../../stores.module';
import {ActivatedRoute, Params} from '@angular/router';
import {BranchService} from '../branch.service';
@Component({
selector: 'app-map',
templateUrl: './map.component.html',
styleUrls: ['./map.component.css']
})
export class MapComponent implements OnInit {
positionMap: Stores;
id: number;
url: string;
constructor(private storeService: BranchService,
private route: ActivatedRoute) { }
ngOnInit() {
this.route.params.subscribe(
(params: Params) => {
this.id = +params['id'];
this.positionMap = this.storeService.getStores(this.id);
}
);
}
}
此代码为name.component.html
<iframe width="6000" height="500" id="gmap_canvas"
src = "https://maps.google.com/maps?q={{positionMap.street}}%20{{positionMap.num}}%20%{{positionMap.city}}&t=&z=20&ie=UTF8&iwloc=&output=embed"
frameborder="0"
scrolling="no"
marginheight="30"
marginwidth="5"
>
</iframe>
我需要
src="https://maps.google.com/maps?q={{positionMap.street}}%20{{positionMap.num}}%20%{{positionMap.city}}&t=&z=20&ie=UTF8&iwloc=&output=embed"
我在URL中绑定positionMap的位置 查看我输入的数据
我想看看例如 “ https://maps.google.com/maps?q=Brookline%20123%20%NewYork&t=&z=20&ie=UTF8&iwloc=&output=embed”
答案 0 :(得分:0)
getUrl(positionMap) {
return "https://maps.google.com/maps?q="+
positionMap.street+"%20"+positionMap.num+"%20%" +
positionMap.city+"&t=&z=20&ie=UTF8&iwloc=&output=embed"
}
然后您可以将html更改为此:
<iframe width="6000" height="500" id="gmap_canvas"
[src] = "getUrl(positionMap)"
frameborder="0"
scrolling="no"
marginheight="30"
marginwidth="5">
</iframe>
类似地,如果您不想使用此方法,则应像当前一样对src进行插值,但是将src
更改为[attr.scr]
要记住的另一件事是,在使用src时,请尝试使用strin插值,例如以下示例:
<img src={{positionMap?.url}} />
这将防止ngViewChecked错误发生后更改,并确保您始终发送字符串。
