我是react/Google Maps新手，我只是想用React js根据用户输入做简单的动态 map 位置指针
但是 Google 标记显示错误的位置。是的，我验证了 lat 和 api 是正确的，但是标记放置出错了..
这是我的代码
import React from 'react';
import Helmet from 'react-helmet';
import {connect} from 'react-redux';
import {setNotificationStatus} from '../Actions/notification_Actions';
import {getPlaces,getLocation,getLocationfromAPI} from '../Actions/post_Actions'
//code from here
class PostCon extends React.Component{
constructor(props){
super(props);
this.state = {
suggestionList:[],
latLong:{lat:0,lng:0},
locationSugg:[],
canLocationRender:false,
calPlacaRender:false,
LocationClassName:'SearchPlaceRi ',
LocationTerm:''
}
this.handlePlaceChange = this.handlePlaceChange.bind(this);
this.handleLocationChange = this.handleLocationChange.bind(this);
}
handlePlaceChange(e){
e.preventDefault();
let searchTerm = e.target.value;
this.props.getPlaces(searchTerm).then((res) => {
this.setState({
suggestionList:res
})
})
}
handleLocationChange(e){
e.preventDefault();
let searchTerm = e.target.value;
this.setState({
LocationTerm:searchTerm,
LocationClassName:'SearchPlaceRi ',
});
let convertedTerm = searchTerm.split(" ").join("+");
// console.log(searchTerm.split(" ").join("+"))
this.props.getLocationfromAPI(convertedTerm).then((res) => {
console.log(res.results)
this.setState({
locationSugg:res.results,
canLocationRender:true
})
})
}
componentDidMount(){
this.props.triggerNotification(true,"Hello From ");
new google.maps.Map(this.refs.map, {
center: this.state.latLong,
zoom: 1,
minZoom:1
});
}
updateState(data){
console.log('Clicked State',data);
let latLong = {lat:data.geometry.location.lat,lng:data.geometry.location.lat}
console.log(latLong);
this.setState({
latLong
})
}
updateStateForLocation(data) {
console.log('clicked Location',data);
let latLong = {lat:data.geometry.location.lat,lng:data.geometry.location.lat}
// console.log(latLong);
this.setState({
LocationClassName:'SearchPlaceRi SelectObject',
canLocationRender:false,
LocationTerm:data.formatted_address,
});
let map = new google.maps.Map(this.refs.map, {
center: latLong,
zoom: 4,
});
new google.maps.Marker({
position: latLong,
map: map,
title: 'Hello World!'
});
new google.maps.Circle({
strokeColor: '#FF0000',
strokeOpacity: 0.8,
strokeWeight: 2,
fillColor: '#000',
fillOpacity: 0.001,
map: map,
center: latLong,
radius: Math.sqrt(603502) * 100
});
this.props.triggerNotification(true,"Tag a place");
}
render(){
// console.log(this.state)

<p>EI had already rated the place 5 when i walked in to Midival Punditz playing on a lazy sunday afternoon...this place is love, from its relaxed ambiance, live grill, bar and an array of Wine to the aroma of cheese wafting in the air. We opted for the sunday Buffet, priced at 1500+ taxes. Along with mouth watering delicacies, choice of veg and non-veg and unlimited Wine and other choice of alcohol, yes you read it right, unlimited, the waffles and pancakes are to die for. Our brunch extended for hours on end with wine freely flowing. The bartender makes some really mean martinis. would love to visit again. Though desserts are a bit letdown, yet, #loveditl</p>

最佳答案
经度设置不正确。此行有错误
let latLong = {lat:data.geometry.location.lat,lng:data.geometry.location.lat}
您正在将 data.geometry.location.lat 设置为 lat 和 lng。
设置经度时将 data.geometry.location.lat 更改为 data.geometry.location.lng
let latLong = {lat:data.geometry.location.lat,lng:data.geometry.location.lng}
