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 🙏

SDK限制,一个地图只允许显示一个infoWindow

amap 模块

它支持下面的方法:

getUserLocation(completeFunc,errorFunc)

获取用户的位置信息

  • completeFunc 定位成功后的回调函数,返回的数据:
{ 
  data:{
    position: []
  },
  result: 'success' 
}
getLineDistance(coor1, coor2, callback)

计算两个标记点的距离

该方法接收三个参数 进行计算比如:

@param coor1 坐标1

@param coor2 坐标2

@param callback 计算完成后的回调 会返回一个计算出的具体距离,单位 米

//...
amap.getLineDistance(this.marker1.position, this.marker2.position, (res) => {
  if (res.result == 'success') {
    this.distance = '两点相距' + res.data + '米';
    console.log(res.data.distance + '米');
  } else {
    console.log('计算失败');
  }
})   
polygonContainsMarker(coor, polygonRef, callbcak)

判断几何形是否包含某个点

该方法接收两个参数,返回一个boolean值

@param coor 点的坐标

@param polygonRef 多边形的ref

@param callbcak 计算完成后的回调 会返回一个运算的结果,其中data字段是个boolean,表示是否包含

amap.polygonContainsMarker([114.23423, 43.2222], this.$ref('polygon2017'), (res) => {
  if (res.result == 'success') {
    console.log(res.data ? '存在' : '不存在' );
  }
})
如何使用amap模块
<template>
  <weex-amap class="map" id="map2017" center="{{pos}}" ></weex-amap>
  <div class="btn-wrap">
    <div onclick="setUserLocation" class="btnbox"><text class="btn" >set location </text></div>
    <text class="tips">进行当前定位</text>
  </div>
</template>

<script>
  const Amap = require('@weex-module/amap');
  module.exports = {
    data: {
      pos:[116.487, 40.00003]
    },
    
    methods: {
      setUserLocation() {
        const self = this;
        Amap.getUserLocation(this.$el('map2017').ref, function (data) {
          if(data.result == 'success') {
            self.pos = data.data.position;
          }
        });  
    }
  };
  
</script>

Demo

H5 demo

直接点击Demo可以演示当前版本支持的功能

用weexpack运行demo(Android/iOS/H5)

参考weexpack命令(网址)来测试地图组件demo:

1.安装weexpack

npm install -g weexpack

2.创建工程,如MyApp

weexpack create MyApp

3.创建运行平台

cd MyApp & weexpack platform add ios (/android)

4.添加地图插件,有两种方式

-从插件市场下载安装: weexpack plugin add weex-amap

-地图插件代码clone到本地后安装, weexpack plugin add /users/abcd/Code/weex-plugins/weex-amap (这后面是地图插件本地代码的目录)

5.编译和运行demo

把demo文件(所有在目录plugins/weex-amap/demos/下的文件)拷贝到项目工程MyApp/src下,然后:

对H5用如下命令:weexpack build web & weexpack run web

对安卓和iOS用命令:weexpack run ios (/android) 可在模拟器或者device上运行

ios demo 如下所示

集成插件

如何将地图插件集成到自己的项目呢,请参考weexpack文档说明
