关于前端:基于-React-封装的高德地图组件帮助你轻松的接入地图到-React-项目中

react-amap 这是一个基于 React 封装的高德地图组件，帮忙你轻松的接入地图到 React 我的项目中。除了必须援用的 Map/APILoader 组件外，咱们目前提供了最罕用的地图组件，能满足大部分简略的业务场景；如果你有更简单的需要，或者感觉默认提供的组件性能不够，你齐全能够自定义一个地图组件，而后依据高德原生 API 做高德容许你做的所有事件。

个性

• ♻️ 主动加载高德地图 SDK（通过创立 Script 标签的模式加载），包含第三方 SDK。
• ???? 应用 Typescript 编写，集成高德地图 SDK @type 申明文件（包含中文正文）。
• ⚛️ 反对 React Hook 新增个性（须要 React 16.8+）。
• ???? 不依赖任何第三方组件。

装置

不依赖 uiw 组件库

npm install @uiw/react-amap --save

应用

import {Map, APILoader} from '@uiw/react-amap';

const Demo = () => (<div style={{ width: '100%', height: '300px'}}>
    <APILoader akay="a7a90e05a37d3f6bf76d4a9032fc9129">
      <Map />
    </APILoader>
  </div>
);
ReactDOM.render(<Demo />, _mount_);

Map 组件

Map 组件是其余组件的根底，Map 组件会给所有的子组件注入两个属性 map，container 和 AMap，

⚠️ 留神

1. 组件 <Map> 必须包裹在 <APILoader> 组件内，该组件作用是加载高德地图 SDK。
2. 其余地图组件必须作为 <Map> 的子组件应用；

import {Map, APILoader} from '@uiw/react-amap';

根本用法

Map 的父组件必须具备宽度和高度；

import React from 'react';
import {Map, APILoader} from '@uiw/react-amap';

const Demo = () => (<div style={{ width: '100%', height: '300px'}}>
    <APILoader akay="a7a90e05a37d3f6bf76d4a9032fc9129">
      <Map />
    </APILoader>
  </div>
);
ReactDOM.render(<Demo />, _mount_);

参数设置

import React, {Fragment} from 'react';
import {Map, APILoader} from '@uiw/react-amap';

function Demo() {const [dragEnable, setDragEnable] = useState(true);
  const [display, setDisplay] = useState(true);
  const [zoom, setZoom] = useState(15);
  const [viewMode, setViewMode] = useState('3D');
  return (
    <Fragment>
      <button onClick={() => setDragEnable(!dragEnable)}>{dragEnable ? '禁用' : '启用'} 拖拽 </button>
      <button onClick={() => setDisplay(!display)}>{display ? '卸载' : '加载'} 地图 </button>
      <button onClick={() => setViewMode(viewMode === '3D' ? '2D' : '3D')}>{viewMode} 地图 </button>
      <button onClick={() => setZoom(zoom + 1)}> 放大 +1 -> ({zoom})</button>
      <button onClick={() => setZoom(zoom - 1)}> 放大 -1 -> ({zoom})</button>
      <div style={{width: '100%', height: 350}}>
        {display && (
          <Map
            dragEnable={dragEnable}
            zoom={zoom}
            viewMode={viewMode}
            pitch={viewMode === '2D' ? 0 : 70}
          />
        )}
      </div>
    </Fragment>
  );
}

ReactDOM.render((
  <APILoader akay="a7a90e05a37d3f6bf76d4a9032fc9129">
    <Demo />
  </APILoader>
), _mount_);

Ref

获取地图实例对象。

import React, {useEffect, useRef, Fragment} from 'react';
import {Map, APILoader} from '@uiw/react-amap';

function Demo() {const mapRef = useRef();
  useEffect(() => {console.log('mapRef:', mapRef)
  }, []);
  return (<div style={{ width: '100%', height: 330}}>
      <Map
        layers={[new AMap.TileLayer.Satellite()]}
        ref={(instance) => {if (instance && instance.map) {const bounds = instance.map.getBounds();
            console.log('instance', instance);
          }
        }}
      />
      <Map
        layers={[new AMap.TileLayer.Satellite()]}
        ref={mapRef}
      />
    </div>
  );
}

ReactDOM.render((
  <APILoader akay="a7a90e05a37d3f6bf76d4a9032fc9129">
    <Demo />
  </APILoader>
), _mount_);

事件触发

import React from 'react';
import {Map, APILoader} from '@uiw/react-amap';

const Demo = () => (<div style={{ width: '100%', height: '300px'}}>
    <APILoader akay="a7a90e05a37d3f6bf76d4a9032fc9129">
      <Map
        onComplete={(data, de) => {console.log('地图加载实现！', data, de);
        }}
        onClick={() => {console.log('点击事件！');
        }}
      />
    </APILoader>
  </div>
);
ReactDOM.render(<Demo />, _mount_);

APILoader

用于加载高德地图 SDK 依赖，加载实现，全局将会有 window.AMap 对象。

import {APILoader} from '@uiw/react-amap';

根本用法

Map 的父组件必须具备宽度和高度；

import React from 'react';
import {Map, APILoader} from '@uiw/react-amap';

const Demo = () => (<div style={{ width: '100%', height: '300px'}}>
    <APILoader akay="a7a90e05a37d3f6bf76d4a9032fc9129">
      <Map />
    </APILoader>
  </div>
);
ReactDOM.render(<Demo />, _mount_);

多个地图

import React from 'react';
import {Map, APILoader} from '@uiw/react-amap';

const Demo = () => (<div style={{ width: '100%', height: 300}}>
    <APILoader akay="a7a90e05a37d3f6bf76d4a9032fc9129">
      <Map style={{height: 100, marginBottom: 10}} />
      <div style={{border: '1px solid red'}}>
        <Map style={{height: 100}} />
      </div>
    </APILoader>
  </div>
);
ReactDOM.render(<Demo />, _mount_);

Marker 点标记组件

点标记是用来标示某个地位点信息的一种地图因素，本章介绍如何在地图图面应用点标记。

import {Marker} from '@uiw/react-amap';

根本用法

import React, {useState, useRef} from 'react';
import {Map, APILoader, Marker} from '@uiw/react-amap';

const Example = () => {const [show, setShow] = useState(true);
  return (
    <>
      <button onClick={() => setShow(!show)}>
        {show ? '暗藏' : '显示'}
      </button>
      <div style={{width: '100%', height: '300px'}}>
        <Map zoom={4}>
          <Marker visiable={show} title="北京市" position={new AMap.LngLat(116.405285,39.904989)} />

点标注的文本标签

import React, {useState, useRef} from 'react';
import {Map, APILoader, Marker} from '@uiw/react-amap';

const Example = () => {const [show, setShow] = useState(true);

              offset: new AMap.Pixel(20, 20),
              // 设置文本标注内容
              content: "<div class='info'> 我是 marker 的 label 标签 </div>",
              // 设置文本标注方位
              direction: 'right'
            }}
            position={new AMap.LngLat(116.405285,39.904989)}
          />

自适应显示多个点标记

import React, {useState, useRef} from 'react';
import {Map, APILoader, Marker} from '@uiw/react-amap';

const Example = () => {const [show, setShow] = useState(true);
  const [map, setMap] = useState();
  return (

      <button onClick={() => setShow(!show)}>
        {show ? '暗藏' : '显示'}
      </button>
      <button onClick={() => {if (map) {map.setFitView(null, false, [150, 60, 100, 60]);
        }
      }}>
        地图自适应显示到适合的范畴
      </button>
      <div style={{width: '100%', height: '300px'}}>
        <Map
          zoom={13}
          center={[116.397428, 39.90923]}

}

ReactDOM.render((
  <APILoader akay="a7a90e05a37d3f6bf76d4a9032fc9129">
    <Example />
  </APILoader>
), _mount_);

Polygon 多边形

结构多边形对象，通过 PolygonOptions 指定多边形款式

import {Polygon} from '@uiw/react-amap';

根本用法

import React, {useState, useRef} from 'react';
import {Map, APILoader, Polygon} from '@uiw/react-amap';

const Example = () => {const [show, setShow] = useState(true);
  // 多边形轮廓线的节点坐标数组
  // const path = [//   new AMap.LngLat(116.368904,39.913423),

  //   new AMap.LngLat(116.387271,39.912501),
  //   new AMap.LngLat(116.398258,39.904600)
  // ];
  const path = [[116.403322, 39.920255],
    [116.410703, 39.897555],
    [116.402292, 39.892353],
    [116.389846, 39.891365]
  ];
  return (
    <>
      <button onClick={() => setShow(!show)}>
        {show ? '暗藏' : '显示'}
      </button>
      <div style={{width: '100%', height: '500px'}}>
        <Map zoom={14} center={[116.400274, 39.905812]}>
          {show && (

Polyline 折线组件

结构折线对象，反对 lineString 和 MultiLineString。

import {Polyline} from '@uiw/react-amap';

根本用法

import React, {useState, useRef} from 'react';
import {Map, APILoader, Polyline, ToolBarControl} from '@uiw/react-amap';

const Example = () => {const [show, setShow] = useState(true);
  return (

      </button>
      <div style={{width: '100%', height: '300px'}}>
        <Map zoom={3}>
          <Polyline

            }}
            onClick={(obj) => {console.log('obj:', obj);
            }}
            strokeColor="black"
            strokeOpacity={1}
            path={[[116.405289, 39.904987],

受控组件
