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 🙏

canvasTurntable

通过 Canvas 根据传入的动态数据绘制大转盘

一、通过 Node 引用

npm i alvin-canvasturntable

在 VUE 的 SPA 中的使用示例:

<template>
  <div id="main">
    <div id="canvasTurntable"></div>
  </div>
</template>
<script>
import createCanvasTurntable from "alvin-canvasturntable";
export default {
  name: "CanvasTurntable",
  data() {
    return {
      canvasTurntable: "",
    };
  },
  mounted() {
    var cfg = {
      targetNodeId: "canvasTurntable",
      sectorText: ["张某某", "李某某", "王某某", "韩某某", "廖某某", "赵某某"],
      rotateTime: 3,
    };
    this.canvasTurntable = createCanvasTurntable(cfg);
  },
};
</script>

二、通过 script 脚本引入

<script type="text/javascript" src="jquery.min.js"></script>
<script type="text/javascript" src="js/CanvasTurntable.min.js"></script>
<div id="CanvasTurntable" style="width:400px; margin:60px auto"></div>

引入上面两个文件之后,即可调用该插件了:

$("#CanvasTurntable").AddCanvasTurntable({
    sectorText: ["张某某", "李某某", "王某某", "韩某某", "廖某某", "赵某某"],
    rotateTime: 3,
});

三、插件可供设置的参数及参数的默认值

$(targetNode).AddCanvasTurntable({
    targetNodeId: "CanvasTurntable", /* 转盘最外层容器的 ID */
    /********** 标签属性设置 **********/
    sectorText: '', /* 扇形的文本值,应设置成数组形式 */
    colors: ["#e9536a","#fbd7a1","#df6679","#000","#fff","#666"], /* 插件用到的颜色,应设置成数组形式 */
    /* 转盘用到的颜色: [扇形颜色一,扇形颜色二,扇形颜色三,扇形字体颜色,指针字体颜色,指针和边框颜色] */
	  /* 当 sectorText.length 为奇数时,最后一块扇形的背景色为颜色三 */
    rotateTime: '', /* 转盘旋转一次的时间,单位 s,默认是 6s */
    alertText: '', /* 全部选中之后的弹框内容 */
    resultTitle: '' /* result 描述 */
});
