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 🙏

安装

  npm install cfy-vue-puzzle-vcode --save

使用

import Vcode from "cfy-vue-puzzle-vcode";

<Vcode
  :show="isShow"
  @onSuccess="onSuccess"
/>
<Vcode
                :show="isVerificationShow"
                :imgs="puzzleImgList"
                :check-fun="check"
                :start-y="startY"
                :refresh="refreshVcode"
                @onSuccess="onSuccess"
                @close="isVerificationShow=false"
              />

最简单例子

<template>
  <Vcode
    :show="isShow"
    @onSuccess="onSuccess"
    @onClose="onClose"
  />
  <button @click="onSubmit">登录</button>
</template>

<script>
  import Vcode from "vue-puzzle-vcode";
  export default {
    data(){
      return {
        isShow: false, // 验证码模态框是否出现
      }
    },
    components:{
      Vcode
    },
    methods:{
      onSubmit(){
        this.isShow = true;
      },
      // 用户通过了验证, msg是用户移动拼图的位置和目标位置的偏差px值
      onSuccess(msg){
        this.isShow = false; // 通过验证后,需要自行隐藏模态框
      },
      // 用户点击遮罩层,应该关闭模态框
      onClose(){
        this.isShow = false;
      }
    }
  }
</script>

参数

| 字段 | 类型 | 默认值 | 说明 | | ------------ | ------- | ------------------ | ---------------------- | | show | Boolean | false | 是否显示验证码弹框 | | canvasWidth | Number | 310 | 主图区域的宽度 | | canvasHeight | Number | 160 | 主图区域的高度 | | imgs | Array | null | 自定义图片,见下方例子 | | successText | String | "验证通过!" | 验证成功时的提示文字 | | failText | String | "验证失败,请重试" | 验证失败时的提示文字 | | sliderText | String | "拖动滑块完成拼图" | 下方滑动条里的文字 |

事件

| 事件名 | 返回值 | 说明 | | --------- | ------ | ------------------------------------------------------------ | | onSuccess | 偏差值 | 验证通过时会触发,返回值是用户移动的距离跟目标距离的偏差值px | | onFail | 偏差值 | 验证失败时会触发,返回值同上 | | onClose | null | 用户点击遮罩层的回调 |

自定义图片

<template>
  <Vcode :imgs="[Img1, Img2]" />
</template>

<script>
import Img1 from '~/assets/img1.png';
import Img2 from '~/assets/img2.png';

export default {
  data(){
    return {
      Img1,
      Img2
    }
  }
}
</script>
  • 也可以是网络图片完整URL路径,但注意图片跨域问题

说明

  • 当不传递imgs字段或图片加载出错时,会自动生成随机图片
  • 模态框的显示和隐藏完全由父级控制,所以用户通过验证后,需要自行隐藏模态框
