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 🙏

翻牌抽奖小程序模块

API

属性名 | 类型 | 默认值 | 描述 | --- | --- | --- | --- prizeList | Array | [] | 奖项列表【必填】,须包含 nameicon 字段 prizeName | String | '' | 抽奖结果的奖品 name【必填】,其值必须位于 prizeList 中 cardNum | Number | 9 | 展示多少张卡片,推荐3/6/9 cardHeight | Number | 210 | 宽度固定210,高度需要等比换算设置 cardBgImg | String | - | 卡背图片 unawardImg | String | - | 未中奖展示图片 isDrawing | Boolean | - | 是否正在抽奖,用于限制点击 flipAllCards | String | - | 是否翻转剩余卡片 onFlipStart | Function | () => {} | 转动开始的回调【选填】

示例

视图:

<view>
<flipdraw
    prizeList="{{prizeList}}"
    prizeName="{{prizeName}}"
    isDrawing="{{isDrawing}}"
    flipAllCards="{{flipAllCards}}"
    onFlipStart="onFlipStart"
  />
</view>

逻辑:

Page({
  data: {
    prizeList: [{
      'name': '谢谢参与1',
      'icon': 'https://zos.alipayobjects.com/rmsportal/dexmbhnbsLRGIZGBqTcA.png'
    }, ... ],
    prizeName: '',
    flipAllCards: false,
    isDrawing: false,
  },
  onFlipStart() {
    console.log('开始了,这个时候最好页面控制下 loading 状态,组件内不做控制');
    this.setData({
      isDrawing: true, // 修改抽奖状态,防止重复点击多次请求
    });
    // 开始抽奖
    drawRequest().then(res => {
      console.log('拿到结果,设置奖品信息');
      if (res.success) {
        this.setData({
          prizeName: '666元红包',
          isDrawing: false,
        });
      } else {
        this.setData({
          isDrawing: false, // 抽奖结束一定要还原 isDrawing 状态
        });
      }
      this.showResultDialog()
    });
  },
  showResultDialog() {
    // do something
    this.setData({
      flipAllCards: true, // 将剩下未翻过的牌自动翻,展示奖品结果。
    })
  }
});

注意

  • 请求前一定要设置 isDrawing = true,请求结束后一定要设置 isDrawing = false。
  • cardHeight 卡片高度是相对750视觉稿设置的,宽高默认210x210rpx。宽度固定,高度可变。比如210x300的图片,cardHeight就设置为300;如果是200x250的图片需要等比转换一下,cardHeight = 210 * (250/200)
