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 🙏

ooomap-geolocation

v1.0.8

Published

ooomap geolocation plugin

Readme

ooomap geolocation

方便在 ooomap SDK 中使用浏览器提供的 navigator.geolocation 获得坐标的插件

会获得3种坐标: 相对坐标(ooomap地图坐标), 墨卡托坐标, 经纬度坐标

安装

npm install ooomap-geolocation --save

引入

使用模块引入

import * as om from "ooomap"
import { GeoLocation } from "ooomap-geolocation"

也可以使用<script>标签引入此插件

创建 GeoLocation 对象

es6:

let geolocation = new GeoLocation( om )

script标签:

let geolocation = new om.GeoLocation( om )

方法

  • start

    • 开始获取位置
    geolocation.start()
  • stop

    • 终止获取位置
    geolocation.stop()

字段

是否暂停

geolocation.pause = true; 	// true or false

事件

在获取到位置后, 会触发 position 事件, 会返回3个坐标, 一个是web墨卡拖坐标{x:, y: }, 还有一个是原始的经纬度坐标{lng:, lat:}

  • 相对坐标(position): {x:, y:}
    • (墨卡托坐标) - (地图中心点center) = 相对坐标
    • 用于在 ooomap 地图中设置位置坐标
  • 墨卡托坐标(mercator): {x:, y:}
  • 经纬度坐标(lnglat): {lng:, lat:}
geolocation.on('position', (position, mercator, lnglat) => {

	console.log(position, mercator, lnglat)

})
