自定义infowindow谷歌地图错误

Question

我正在尝试自定义Google地图的信息窗口，但我无法删除白框。

有人可以帮助我吗？

代码（CSS）：

import { Component, OnInit, Input } from '@angular/core';

import { ActivatedRoute } from '@angular/router';

import { Observable } from 'rxjs/Observable';

import { AngularFireDatabase } from 'angularfire2/database';

import { AngularFirestore, AngularFirestoreCollection, AngularFirestoreDocument } from 'angularfire2/firestore';

import { AuthService } from '../../services/auth.service';

import { Invoice } from '../invoiceModel';

@Component({
  selector: 'app-view-invoice',
  templateUrl: './view-invoice.component.html',
  styleUrls: ['./view-invoice.component.scss']
})

export class ViewInvoiceComponent implements OnInit {

  userId: string;

  invoiceId: any;

  invoicesCollection: AngularFirestoreCollection<Invoice>;
  invoices: Observable<Invoice[]>;

  invoice: Observable<Invoice>;

  constructor(private authService: AuthService, private db: AngularFirestore, private route: ActivatedRoute) {
      this.userId = this.authService.user.uid;

      this.route.params.subscribe(params => {
        this.invoiceId = params.id;
      })

      this.invoicesCollection = this.db.collection('/invoices');

      this.invoices = this.invoicesCollection.snapshotChanges().map(changes => {
          return changes.map(a => {
            const data = a.payload.doc.data() as Invoice;
            data.id = a.payload.doc.id;
            return data;
          })
      })
  }

  ngOnInit() {
    this.getInvoice();
  }

  getInvoice() {
    var docref = this.db.collection('/users').doc(this.authService.user.uid).collection('/invoices').doc(this.invoiceId);
    docref.ref.get()
        .then(function(doc) {
            if (doc.exists) {
                var invoice = doc.data(); <------WORKS
                // this.invoice = doc.data(); <------DOESN'T WORK
                console.log('Invoice data: ', doc.data());
            } else {
                console.error('No matching invoice found');
            }
    })
  }

}

Answer 1

将/*Code to remove arrow and close button*/下的规则替换为：

.gm-style div div div div div div div {
  visibility: hidden;
}
.gm-style-iw + div {
  display: none;
}
.gm-style div div div div div div.gm-style-iw div div {
  visibility: visible;
}

第一条规则隐藏了白框，但也隐藏了黑色信息窗口中的文字，因此第三条规则使文字再次可见。

看一下this JSBin，看一个有效的例子。
