当搜索(使用邮政编码)发生时,我的 Google 地图渲染出现问题。似乎地图正在渲染空地图中心,然后在 componentDidMount() 中的 setState 之后不重新渲染,因为地图呈现为空白/灰色,但通过硬刷新,地图将与邮政编码一起加载。我试过使用 componentWillMount() 没有任何运气,有人有什么建议吗?
这是我的搜索页面的代码:
class SearchContainer extends Component {
constructor(props) {
super(props);
this.state = {
map_centre: null
};
}
componentDidMount() {
const values = queryString.parse(this.props.location.search);
axios
.get("api/v1/search?postcode=" + values.postcode)
.then(response => {
var mapCentre = response.data.map_centre;
this.setState({
map_centre: mapCentre
});
})
.catch(error => console.log(error));
}
render() {
return (
<div id="map" className="padding-left">
<GoogleMapComponent
townCenters={this.state.townCenters}
schools={this.state.schools}
supermarkets={this.state.supermarkets}
hotels={this.state.hotels}
airports={this.state.airports}
trainStations={this.state.trainStations}
map_centre={this.state.map_centre}
onMapMounted={this.handleMapMounted}
onDragEnd={this.handleMapChange}
onZoomChanged={this.handleMapChange}
onMarkerClick={this.handleAdspaceShow}
googleMapURL={url}
loadingElement={<div style={{ height: `100vh`, width: `100%` }} />}
containerElement={<div style={{ height: `100vh`, width: `100%` }} />}
mapElement={<div style={{ height: `100vh`, width: `100%` }} />}
/>
<img
src={mapSearch}
id="map-search-button"
onClick={this.toggleSearchInput}
/>
<input
id="map-search-input"
className="form-control d-none"
type="search"
placeholder="Enter new location"
aria-label="Search"
onChange={this.handlePostcodeChange}
onKeyPress={this.handleNewSearch}
/>
</div>
);
}
}
这是我的谷歌地图组件的代码:
const GoogleMapComponent = withScriptjs(
withGoogleMap(props => (
<GoogleMap
defaultZoom={13}
defaultCenter={props.map_centre}
onDragEnd={props.onDragEnd}
onZoomChanged={props.onZoomChanged}
ref={props.onMapMounted}
/>
))
);
