点标记是用来标示某个位置点信息的一种地图要素,本章介绍如何在地图图面使用点标记。
import { Text } from '@uiw/react-amap';
// 或者单独安装使用
import { Text } from '@uiw/react-amap-text';
import ReactDOM from 'react-dom';
import React, { useState, useRef } from 'react';
import { Map, APILoader, Text } from '@uiw/react-amap';
const Example = () => {
const [show, setShow] = useState(true);
return (
<>
<button onClick={() => setShow(!show)}>
{show ? '隐藏' : '显示'}
</button>
<div style={{ width: '100%', height: '300px' }}>
<Map zoom={13} center={[116.4, 39.92]}>
<Text
text="纯文本标记"
anchor="center"
draggable={true}
cursor="pointer"
angle={10}
visiable={show}
style={{
'padding': '.75rem 1.25rem',
'margin-bottom': '1rem',
'border-radius': '.25rem',
'background-color': 'white',
'width': '15rem',
'border-width': 0,
'box-shadow': '0 2px 6px 0 rgba(114, 124, 245, .5)',
'text-align': 'center',
'font-size': '20px',
'color': 'blue'
}}
// title="北京市"
position={new AMap.LngLat(116.396923,39.918203)}
/>
</Map>
</div>
</>
);
}
const Mount = () => (
<APILoader akey="a7a90e05a37d3f6bf76d4a9032fc9129">
<Example />
</APILoader>
);
export default Mount;

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

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

draggable={true}

const Mount = () => (
<APILoader akey="a7a90e05a37d3f6bf76d4a9032fc9129">

</APILoader>
);
export default Mount;
由于 text 参数与返回的 text 冲突,定义类型参考如下实例
import ReactDOM from 'react-dom';
import React, { useEffect, useRef } from 'react';
import { Text, TextProps } from './index';
function Demo() {
const textRef = useRef<Omit<TextProps, 'text'> & { text?: AMap.Text }>(null);
useEffect(() => {
if (textRef.current && textRef.current.text) {
textRef.current.text.setStyle({});
}
}, []);
return (
<>
<Text ref={textRef} text="test" />
<Text
ref={(instance) => {
if (instance && instance.map && instance.text) {
const bounds = instance.map?.getBounds()
const txt = instance.text.getBounds();
}
}}
text="test"
/>
</>
);
}
