NavigationControl 平移缩放控件

地图的平移缩放控件，可以对地图进行上下左右四个方向的平移和缩放操作。你也可以使用 Map 组件 widget 属性来设置控件更方便。

import { NavigationControl, useNavigationControl } from '@uiw/react-baidu-map';
// 或者单独安装使用
import NavigationControl, { useNavigationControl } from '@uiw/react-baidu-map-navigation-control';

基本用法

import React, { useState } from 'react';
import { Map, APILoader, NavigationControl } from '@uiw/react-baidu-map';

const Example = () => {
  const [show, setShow] = useState(true);
  const [type, setType] = useState(BMAP_NAVIGATION_CONTROL_LARGE);
  return (
    <>
      <button> setShow(!show)}&gt;
        {show ? '关闭' : '开启'}
      </button>
      <button> setType(BMAP_NAVIGATION_CONTROL_PAN)}&gt;
        平移按钮
      </button>
      <button> setType(BMAP_NAVIGATION_CONTROL_ZOOM)}&gt;
        缩放按钮
      </button>
      <button> setType(BMAP_NAVIGATION_CONTROL_SMALL)}&gt;
        平移和缩放按钮
      </button>
      <button> setType(BMAP_NAVIGATION_CONTROL_LARGE)}&gt;
        恢复默认
      </button>
      <map style="{{">
        {show &amp;&amp; (
          
        )}
        
      </map>
    
  );
}

const Demo = () =&gt; (
  <div style="{{">
    
      
    
  </div>
);
export default Demo;

使用 hooks

navigationControl, setNavigationControl

import React from 'react';
import { useRef, useEffect, useState } from 'react';
import { Map, APILoader, Provider, useMap, useNavigationControl } from '@uiw/react-baidu-map';

const Example = () => {
  const divElm = useRef(null);
  const { setContainer, map } = useMap();
  const { navigationControl } = useNavigationControl({
    type: BMAP_NAVIGATION_CONTROL_SMALL
  });

  useEffect(() => {
    if (divElm.current && !map) {
      setContainer(divElm.current);
    }
  }, [map]);
  return (
    <>
      <button> navigationControl.setType(BMAP_NAVIGATION_CONTROL_PAN)}&gt;
        平移按钮
      </button>
      <button> navigationControl.setType(BMAP_NAVIGATION_CONTROL_LARGE)}&gt;
        平移、缩放按钮和滑块
      </button>
      <div style="{{">
    
  );
}

const Demo = () =&gt; (
  <div style="{{">
    
      
        
      
    
  </div>
);
export default Demo;
