React使用高德地图的实现示例（react-amap）

React使⽤⾼德地图的实现⽰例（react-amap）react-amap 安装
1、使⽤npm进⾏安装，⽬前是1.2.8版本：
cnpm i react-amap
2、直接使⽤sdn⽅式引⼊
<script src="https:///react-amap@0.2.5/dist/react-amap.min.js"></script>
react-amap 使⽤
import React,{Component} from 'react'
import {Map,Marker} from 'react-amap'
const mapKey = '1234567809843asadasd' //需要⾃⼰去⾼德官⽹上去申请
class Address extends Component {
constructor (props) {
super (props)
this.state = {
}
}
render(){
return (
<div style={{width: '100%', height: '400px'}}>
<Map amapkey={mapKey}
zoom={15}></Map>
</div>
)
}
}
export default Address
这样的话，就会初始化⼀个简单的地图。

实际开发过程中，你会有⽐较复杂的使⽤场景。

⽐如需要标记点、对地图进⾏缩放、能够定位到当前位置、位置搜索等等功能。

需求⼤致如下图所⽰：
ToolBar、Scale插件
<Map plugins={["ToolBar", 'Scale']}></Map>
Marker 地图标记
<Map>
<Marker position={['lng','lat']}></Marker>
</Map>
InfoWindow 窗体组件
<Map>
<InfoWindow
position={this.state.position}
visible={this.state.visible}
isCustom={false}
content={html}
size={this.state.size}
offset={this.state.offset}
events={this.windowEvents}
/>
</Map>
通过 created 事件实现更⾼级的使⽤需求，在⾼德原⽣实例创建成功后调⽤，参数就是创建的实例；获取到实例之后，就可以根据⾼德原⽣的⽅法对实例进⾏操作：
const events = {
created: (instance) => { console.log(instance.getZoom())},
click: () => { console.log('You clicked map') }
}
<Map events={events} />
实现⼀个较为复杂地址搜索，地址标记、逆地理解析代码：
import React , { Component } from 'react'
import { Modal , Input } from 'antd'
import styles from './index.scss'
import classname from 'classnames'
import { Map ,Marker,InfoWindow} from 'react-amap'
import marker from 'SRC/statics/images/signin/marker2.png'
const mapKey = '42c177c66c03437400aa9560dad5451e'
class Address extends Component {
constructor (props) {
super(props)
this.state = {
signAddrList:{
name:'',
addr:'',
longitude: 0,
latitude: 0
},
geocoder:'',
searchContent:'',
isChose:false
}
}
//改变数据通⽤⽅法(单层)
changeData = (value, key) => {
let { signAddrList } = this.state
signAddrList[key] = value
this.setState({
signAddrList:signAddrList
})
}
placeSearch = (e) => {
this.setState({searchContent:e})
}
searchPlace = (e) => {
console.log(1234,e)
}
componentDidMount() {
}
render() {
let { changeModal , saveAddressDetail } = this.props
let { signAddrList } = this.state
const selectAddress = {
created:(e) => {
let auto
let geocoder
window.AMap.plugin('AMap.Autocomplete',() => {
auto = new window.AMap.Autocomplete({input:'tipinput'});
})
window.AMap.plugin(["AMap.Geocoder"],function(){
geocoder= new AMap.Geocoder({
radius:1000, //以已知坐标为中⼼点，radius为半径，返回范围内兴趣点和道路信息 extensions: "all"//返回地址描述以及附近兴趣点和道路信息，默认"base"
});
});
window.AMap.plugin('AMap.PlaceSearch',() => {
let place = new window.AMap.PlaceSearch({})
let _this = this
window.AMap.event.addListener(auto,"select",(e) => {
place.search()
geocoder.getAddress(e.poi.location,function (status,result) {
if (status === 'complete'&&result.regeocode) {
let address = result.regeocode.formattedAddress;
let data = result.regeocode.addressComponent
let name = data.township +data.street + data.streetNumber
_this.changeData(address,'addr')
_this.changeData(name,'name')
_this.changeData(e.poi.location.lng,'longitude')
_this.changeData(t,'latitude')
_this.setState({isChose:true})
}
})
})
})
},
click:(e) => {
const _this = this
var geocoder
var infoWindow
var lnglatXY=new AMap.LngLat(e.lnglat.lng,t);
let content = '<div>定位中....</div>'
window.AMap.plugin(["AMap.Geocoder"],function(){
geocoder= new AMap.Geocoder({
radius:1000, //以已知坐标为中⼼点，radius为半径，返回范围内兴趣点和道路信息 extensions: "all"//返回地址描述以及附近兴趣点和道路信息，默认"base"
});
geocoder.getAddress(e.lnglat,function (status,result) {
if (status === 'complete'&&result.regeocode) {
let address = result.regeocode.formattedAddress;
let data = result.regeocode.addressComponent
let name = data.township +data.street + data.streetNumber
_this.changeData(address,'addr')
_this.changeData(name,'name')
_this.changeData(e.lnglat.lng,'longitude')
_this.changeData(t,'latitude')
_this.setState({isChose:true})
}
})
});
}
}
return (
