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 🙏

ContextMenu 右键菜单

Buy me a coffee npm version Downloads

地图图面一种特殊的信息窗体,即右键菜单。AMap.ContextMenu 类提供图面添加右键菜单的方式。具体使用方式如下

import { ContextMenu } from '@lbh7/react-amap';
// 或者单独安装使用
import { ContextMenu } from '@lbh7/react-amap-context-menu';

基本用法

地图上右击鼠标,弹出自定义样式的右键菜单

import ReactDOM from 'react-dom';
import React, { useState, useRef } from 'react';
import { Map, APILoader, ContextMenu } from '@lbh7/react-amap';

const Example = () => {
  const [show, setShow] = useState(true);
  const mapRef = useRef();
  let lnglat = null;

  function handleMenu(type) {
    if (mapRef && mapRef.current && mapRef.current.map) {
      switch(type) {
        case 'zoomIn': mapRef.current.map.zoomIn(); break;
        case 'zoomOut': mapRef.current.map.zoomOut(); break;
        case 'center': mapRef.current.map.setZoomAndCenter(4, [108.946609, 34.262324]); break;
      }
      if (type === 'marker' && lnglat) {
        new AMap.Marker({
            map: mapRef.current.map,
            position: lnglat //基点位置
        });
      }
    }
  }
  return (
    <div style={{ width: '100%', height: '500px' }}>
      <Map
        ref={mapRef}
        zoom={14}
        center={[116.397637, 39.900001]}
        scrollWheel={false}
        onRightClick={(e) => {
          lnglat = e.lnglat;
        }}
      >
        <ContextMenu>
          <ContextMenu.Item text="放大一级" onClick={(e) => handleMenu('zoomIn')} />
          <ContextMenu.Item text="缩小一级" onClick={(e) => handleMenu('zoomOut')} />
          <ContextMenu.Item text="缩放至全国范围" onClick={(e) => handleMenu('center')} />
          <ContextMenu.Item text="添加标记" onClick={(e) => handleMenu('marker')} />
        </ContextMenu>
      </Map>
    </div>
  );
}

const Mount = () => (
  <APILoader akey="a7a90e05a37d3f6bf76d4a9032fc9129">
    <Example />
  </APILoader>
);

export default Mount;
