Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

PolygonEditor 编辑器

Buy me a coffee npm version Downloads

Polygon 多边形编辑器,此组件只支持AMap JS API v2.0 及以上版本。想在低版本 AMap (如 V1.4.15及以下)中使用拆线编辑功能可以查看 PolyEditor 编辑器AMap API

import { PolygonEditor } from '@uiw/react-amap';
// 或者单独安装使用
import { PolygonEditor } from '@uiw/react-amap-polygon-editor';

基本用法

注意,需要加载 <APILoader plugin="AMap.PolygonEditor">,需要加载 AMap.PolygonEditor 插件,如果点击进入当前页面,需要 刷新 页面。

<APILoader plugin="AMap.PolygonEditor">
import ReactDOM from 'react-dom';
import React, { useState, useRef } from 'react';
import { Map, APILoader, Polygon, PolygonEditor } from '@uiw/react-amap';

const Example = () => {
  const [show, setShow] = useState(true);
  const [active, setActive] = useState(false);
  // 多边形轮廓线的节点坐标数组
  const path = [
    [116.403322, 39.920255],
    [116.410703, 39.897555],
    [116.402292, 39.892353],
    [116.389846, 39.891365],
  ];
  const [polygonPath,setPolygonPath]=useState(path);

  return (
    <>
      <button onClick={() => setShow(!show)}>
        {show ? '隐藏' : '显示'}
      </button>
      <button onClick={() => setActive(!active)}>
        {active ? '结束' : '开始'}编辑
      </button>
      <div style={{ width: '100%', height: '500px' }}>
        <Map zoom={14} center={[116.400274, 39.905812]}>
          <Polygon
            visible={show}
            path={polygonPath}
            strokeColor="#FF33FF"
            strokeWeight={6}
            strokeOpacity={0.2}
            fillOpacity={0.4}
            fillColor="#1791fc"
            zIndex={50}
          >
            <PolygonEditor
              active={active}
              onEnd={(e) => {
                if (e.target) {
                  setPolygonPath(e.target.getPath())
                }
              }}
              onAdjust={() => {
                console.log('onAdjust:>>')
              }}
              onMove={() => {
                console.log('onMove:>>')
              }}
              onAdd={() => {
                console.log('onAdd:>>')
              }}
              onAddnode={() => {
                console.log('onAddnode:>>')
              }}
              onRemovenode={() => {
                console.log('onRemovenode:>>')
              }}
            />
          </Polygon>
        </Map>
      </div>
    </>
  );
}

const Mount = () => (
  <APILoader akey="a7a90e05a37d3f6bf76d4a9032fc9129" plugin="AMap.PolygonEditor">
    <Example />
  </APILoader>
);

export default Mount;

Props

| 参数 | 说明 | 类型 | 默认值 | |--------- |-------- |--------- |-------- | | active | 是否开启编辑功能。 | boolean | - | | onAddnode | 增加一个节点时触发此事件 | (data :{target: Polygon, lnglat: Lnglat, pixel: Pixel}): void; | | onRemovenode | 移除一个节点时触发此事件 | (data :{target: Polygon, lnglat: Lnglat, pixel: Pixel}): void; | | onAdjust | 调整折线上某个点时触发此事件 | (data :{target: Polygon, lnglat: Lnglat, pixel: Pixel}): void; | | onMove | 移动覆盖物时触发此事件 | (data :{target: Polygon, lnglat: Lnglat, pixel: Pixel}): void; | | onAdd | 创建一个覆盖物之后触发该事件,target即为创建对象。当editor编辑对象为空时,调用open接口,再点击一次屏幕就会创建新的覆盖物对象 | (data :{target: Polygon}): void; | | onEnd | 调用close之后触发该事件,target即为编辑后的覆盖物对象 | (data :{target: Polygon}): void; |
