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 🙏

前言

mpvue开源之初写了 用 vue 写小程序,基于 mpvue 框架重写 weui。当时用的是小程序的原生组件,没有对其进行封装和组件化。而对于现在的前端开发环境,组件化模块化工程化以及自动化已经是一种标配。而mpvue框架又提供了一个很好的组件化开发平台,因此就对小程序中的 picker 组件进行封装,使其在用mpvue开发的时候能够用快速的实现 picker的功能。

:warning:uni-app 插件市场的 mpvue-picker 不是本人在维护,如果要在 uni-app 中使用的话推荐通过 npm 包的方式引入。

为什么封装 picker 组件

  • 其实小程序提供了原生的 picker 组件,但是在开发的时候会发现在 android 手机上看到的 picker效果与微信开发者工具预览的效果不一样,其实就是丑了一点点...

  • 在小程序中使用 picker 的地方很多,很常见。

使用

  • 安装
npm install mpvue-picker --save
  • 在页面中使用
<template>
  <div class="mpvue-picer">
    <button @click="showPicker">test for mpvuePicker</button>
    <mpvue-picker ref="mpvuePicker" :mode="mode" :pickerValueDefault="pickerValueDefault" @onChange="onChange" @onConfirm="onConfirm" @onCancel="onCancel" :pickerValueArray="pickerValueArray"></mpvue-picker>
  </div>
</template>

<script>
import mpvuePicker from 'mpvue-picker';
export default {
  components: {
    mpvuePicker
  },
  data() {
    return {
      mode: 'selector',
      pickerValueArray: [
        {
          label: '住宿费',
          value: 1
        },
        {
          label: '活动费',
          value: 2
        },
        {
          label: '通讯费',
          value: 3
        },
        {
          label: '补助',
          value: 4
        }
      ],
      pickerValueDefault: [1]
    };
  },
  methods: {
    showPicker() {
      this.$refs.mpvuePicker.show();
    },
    onConfirm(e) {
      console.log(e);
    },
    onChange(e) {
      console.log(e);
    },
    onCancel(e) {
      console.log(e);
    }
  }
};
</script>

<style>

</style>

在父组件中调用 mpvuePicker 实例中的 show 方法即可

this.$refs.mpvuePicker.show();

          }
        ]
      }
    ]
  }
]

相关说明

对于多级联动,由于没有动态添加 picker 列数以及动态渲染其值,因此目前只支持 二级联动和三级联动。
