【问题描述】：
我是 react/Google 地图的新手，我只是想根据用户输入使用 React js 做简单的动态地图位置指针
但是谷歌标记显示错误的地方。是的，我验证了纬度和 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({

<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>
