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 🙏

实例方法
var as = new AreaSelector();

as.setParams({ key: 'value' }); // 会立即触发一次数据请求

as.clearAll(); // 清空当前选择项

as.getModel(); // 获取当前的选择信息

调用方式

简单实例
<div id="app"></div>
as = new AreaSelector(document.getElementById('app'), {
  api: '/api/filter',
  typeMap: {
    '交易平台BU': { id: 'bu', params: { key1: 'value1' } }    // 请求会组装成 /api/filter/bu?key1=value1
  },
  types: ['交易平台BU', '城市'],
  cache: true,
  onReady: function() { console.log('ready!') },
  onChange: function() { console.log('changed! current value is:', as.getModel()) }, // { level: 1, data: '123,3453,676,1' }
  onTypeChange: function(type) { console.log('current type is:', type) }
})
内置类型列表
{
  '交易平台BU': { id: 'bu', params: { time: 'hour' } },
  '红包': { id: 'redReward' },
  'BOD': { id: 'bod' },

使用内置类型
new AreaSelector(document.getElementById('app'), {
  types: ['交易平台BU', '城市'],
  responseHandler: (data, success) => {
    if (data && data.code === 200 && data.data) {
      return data.data;
    }
  }
})
使用自定义类型
new AreaSelector(document.getElementById('app'), {
  api: '/api/filter',
  typeMap: {
    '自定义': { id: 'custom', params: { key1: 'value1' } }
  },
  // 请求会组装成 /api/filter/custom?key1=value
  types: ['自定义'],
  responseHandler: (data, success) => {
    if (data && data.code === 200 && data.data) {
      return data.data;
    }
  }
})
