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 🙏

pie

饼图组件,包括选中效果、文字说明等常见的饼图。

如何使用?

首先,需要安装npm包(目前我们仅支持npm方式管理):

npm install --save clunch @clunch/pie

然后注册组件:

import Clunch from 'clunch';
import pie from '@clunch/pie';

Clunch.series('ui-pie',pie);

然后,你就可以使用这个组件了:

<ui-pie data='Array' />
  • data:数据,应该是一个数组(比如:[{value:120,name:"苹果"},...]

除了上面的必输项外,还有下列可选项:

|属性|类型|描述|默认值|可选值| |----|----|----|----|----| |cx|number|图形中心位置横坐标|画布中心横坐标|| |cy|number|图形中心位置纵坐标|画布中心纵坐标|| |radius|number|图形半径|画布最小边的30%|| |inner-radius|number|图形内半径|0|| |label-show|boolean|是否显示提示文字|true| |colors|Array<string>|饼的颜色|内置循环色|| |border-show|boolean|是否显示边框轮廓|true||

由于此组件是基于Clunch开发的,我们默认你已经掌握了相关知识。

交互事件

图形绘制完成以后,我们可能还需要图形是可交互的,比如鼠标点击某个条目,可以提示对应的信息。

那么,我们可以对.clunch改造一下:

<ui-pie data='Array' c-on:click='doit'/>

然后,在new Clunch的时候添加doit方法

new Clunch({
    ......
    methods:{
        doit(target){
            console.log(target);
        }
    }
});

打印的结果如下:

target = {
    attr:当前组件的属性值
    data:你点击区域的信息
    left:点击位置的横坐标
    top:点击位置的纵坐标
    region:点击区域名称
    subRegion:点击子区域名称
    ......
}

其中,target.subRegion的格式举例子:'0',表示你点击的是第一个饼块。

这样子,你就可以添加弹框或者悬浮提示来实现和绘制图形的交互了!
