Initialize React Google Maps StandaloneSearchBox with geocode

问题

Can someone tell me how to initialize React Google Maps's StandaloneSearchBox component with types: ['geocode'] (like in the original google.maps.places.Autocomplete, so i can restrict the autocomplete's suggestions of the input?

回答1:

StandaloneSearchBox is a wrapper around google.maps.places.SearchBox.
So Google documentation for SearchBox says that:

The SearchBox constructor takes two arguments:

An HTML input element of type text. This is the input field that the SearchBox service will monitor and attach its results to.

An options argument, which can contain the bounds property: bounds is a google.maps.LatLngBounds object specifying the area in which to search for places. The results are biased towards, but not restricted to, places contained within these bounds.

Source: https://developers.google.com/maps/documentation/javascript/places-autocomplete#places_searchbox

So you can call this component like this:

<StandaloneSearchBox
      ref={props.onSearchBoxMounted}
      bounds={props.bounds}
      onPlacesChanged={props.onPlacesChanged}
      defaultBounds={new google.maps.LatLngBounds(
            new google.maps.LatLng(40.712216, -74.22655),
            new google.maps.LatLng(40.773941, -74.12544)
      )}

Where defaultBounds is a LatLngBounds class which is represents a rectangle in geographical coordinates.

I was able to do something like this with alexandar's suggestion. Pass an address into the address search and use geocode to do a near by search. Hope this helps.

import React from 'react';
import { compose, withProps, lifecycle } from 'recompose';
import { withScriptjs } from 'react-google-maps';
import StandaloneSearchBox from 'react-google-maps/lib/components/places/StandaloneSearchBox';
import get from 'lodash/get';
import head from 'lodash/head';
import { Search } from '../components';

const GOOGLE_API_KEY = '123';

const AddressSearchbox = compose(
  withProps(props => {
    return {
      ...props,
      googleMapURL: `https://maps.googleapis.com/maps/api/js?key=${GOOGLE_API_KEY}&v=3.exp&libraries=geometry,drawing,places`,
      loadingElement: <div style={{ height: `100%` }} />,
      containerElement: <div style={{ height: `400px` }} />,
    };
  }),
  withScriptjs,
  lifecycle({
    componentDidMount() {
      const refs = {};

      this.setState({
        places: [],
        searchText: '',
        error: null,
        onSearchBoxMounted: ref => {
          refs.searchBox = ref;
        },
        onPlacesChanged: () => {
          const places = refs.searchBox.getPlaces();
          this.setState({
            places,
            searchText: '',
          });
        },
      });

      ***
      const geocoder = new google.maps.Geocoder();
      geocoder.geocode({ address: this.props.placeName }, (results, status) => {
      if (status === google.maps.DirectionsStatus.OK) {
        const lngs = results[0].geometry.bounds.j;
        const lats = results[0].geometry.bounds.l;
        this.setState({
          boundSearch: new google.maps.LatLngBounds(
            new google.maps.LatLng(lats.l, lngs.l),
            new google.maps.LatLng(lats.j, lngs.j)
          ),
        });
      } else {
        this.setState({
          error: status,
        });
      }
      ***
      });
    },
  })
)(props => {
  return (
    <div data-standalone-searchbox="">
      <StandaloneSearchBox
        ref={props.onSearchBoxMounted}
        onPlacesChanged={props.onPlacesChanged}
        bounds={props.boundSearch}
      >
        <Search searchText={props.searchText} />
      </StandaloneSearchBox>
      <div>{get(head(props.places), 'formatted_address')}</div>
    </div>
  );
});

export default AddressSearchbox;

<AddressSearchbox address="cleveland, oh" />
