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 🙏

const datePicker = new Picker({
        id: 'datePicker',
        wheels: [
            {data:['周日','周一','周二','周三','周四','周五','周六']},

        onConfirm: function (data) {
            console.log(data);
        }
    });

datePicker.showPicker(['周二', '10:00']);

在React中使用在Vue中使用

parame

| 参数 | 类型 | 说明 | 是否必填 | | ------------- | -------- | ------------------------------------------------------------ | -------- | | id | String | 模块ID,模块根节点将以此为id,部分子节点将添加class=“id_功能名” 作为className用于覆写样式(能通过style参数设置样式的尽量不要通过className去覆写),默认id=MobileSelect_时间戳_100位随机数 | 否 | | parentId | String | 模块挂载的父节点, | 否 | | emBase | Number | 基础字体大小,模块采用em为单位制,子节点元素单位em的参考值,比如{emBase:20}则相当于1em=20px | 否 | | trigger | String | 引用picker页面的目标触发node,用于点击以唤起picker | 必填 | | title | String | 设置picker的标题 | 否 | | wheels | Object | picker的原始数据,这里控制picker选择器的类型,见wheels数据结构 | 必填 | | keyMap | Object | 当wheels为 “联动数据结构” 或者 “{ key: value }数据结构” 时用来定义picker显示的数据结构(具体参照wheels数据结构) | 否 | | defaultValue | Array | 创建picker初始化时默认选择的值,请使用keyMap中valve对应定义的key的值 | 否 | | style | Object | 控制picker的样式,见style附表 | | | onConfirm | Function | 点击确认时的回调,以参数形式返回被选中的结果 | 否 | | onCancel | Function | 点击取消或者遮罩层时的回调,以参数形式返回上次选中的结果 | 否 | | transitionEnd | Function | 滚动结束时的回调,以参数形式返回被选中的结果 | 否 | | onShow | Function | 显示picker时的回调,返回picker对象 | 否 | | onHide | Function | 隐藏picker时的回调,返回picker对象 | 否 | | onChange | Function | 改变选择时的回调,以参数形式返回被选中的结果 | 否 |

options

new Picker().updatePicker(value)

用于更新picker默认值,value是要更新的值,value是一个数组,每一项代表每列轮子的默认值。如果定义了keyMap请使用keyMap中valve对应定义的值;

​ ex:假设picker的数据与keyMap定义如下

wheelsdata = [
    {
        data: [
            { val: 0, date: '周日' },
            { val: 1, date: '周一' },
            { val: 2, date: '周二' },
            { val: 3, date: '周三' },
            { val: 4, date: '周四' },
            { val: 5, date: '周五' },
            { val: 6, date: '周六' }
        ]
    },
    {
        data: [
            { val: 8, date: '08:00' },
            { val: 9, date: '09:00' },
            { val: 10, date: '10:00' },
            { val: 11, date: '11:00' },
            { val: 12, date: '12:00' },
            { val: 13, date: '13:00' },
            { val: 14, date: '14:00' }
        ]
    }
]

keyMap = {display: 'date', value: 'val'}

​ value值应当是每列的data[keyMap.value]组成的数组。

**比如我们要updatePicker默认值到周日的9:00,那么value值应该是 **value = [0,9]

new Picker().showPicker(value);

显示picker,有参数时定位到参数值位置再显示picker, 参数value值同updatePicker的参数值

new Picker().getCurValue();

获取当前选中结果的值

new Picker().distory();

销毁picker,注意这里仅对主要事件侦听器以及创建picker时生成的html节点的移除,外部对象请自行销毁,比如

var newPicker = new Picker({...});
newPicker.distory();
newPicker = null; // 完全销毁生成的picker对象

wheels数据结构

  • 基础数据结构

    root数组中每一个Object为一个滚动wheel列,data数组的每一项为当前wheel列的每一项

    [
        {data:['周日','周一','周二','周三','周四','周五','周六']},     
        {data:['08:00','09:00','10:00','11:00','12:00','13:00','14:00']}
    ]
  • { key: value } 数据结构

    这类数据常用于显示信息与对应值分开展示的场景,root数组中每一个Object为一个滚动wheel列,data数组的每一项为当前wheel列的每一项;

    这里需要注意的是默认情况下Picker以name作为展示key,以value作为取值key,如果您的当前数据对象没有这两个key或者需要指定数据时需要通过keyMap来通知Picker当前数据哪个key是用于显示的, 比如下面数据就需要指定keyMap = { display: 'date', value: 'val'}

    [
        {
            data: [
                { val: 0, date: '周日' },
                { val: 1, date: '周一' },
                { val: 2, date: '周二' },
                { val: 3, date: '周三' },
                { val: 4, date: '周四' },
                { val: 5, date: '周五' },
                { val: 6, date: '周六' }
            ]
        },
        {
            data: [
                { val: 8, date: '08:00' },
                { val: 9, date: '09:00' },
                { val: 10, date: '10:00' },
                { val: 11, date: '11:00' },
                { val: 12, date: '12:00' },
                { val: 13, date: '13:00' },
                { val: 14, date: '14:00' }
            ]
        }
    ]
  • 联动数据结构

    联动数据常用于父子关系数据的展示,他的显示信息与对应值也是分开展示的场景,数据中的每一个层级关系代表列一个wheel列,平级数组的每一个对象为当前wheel列的每一项,依次到最后一个子集。wheels子集嵌套越深,Picker的列数也就越多

    这里需要注意的是同 “{ key: value } 数据” 结构一样需要通过keyMap来通知Picker当前数据哪个key是用于显示的, 比如下面数据就需要指定keyMap = { display: 'date', value: 'val', childs: 'childs'}

    [
        {
            data: [
                {
                    val: 'a',
                    date: 'A',
                    childs: [
                        {
                            val: 'a-a',
                            date: 'A-A',
                            childs: [
                                {
                                    val: 'a-a-a',
                                    date: 'A-A-A',
                                },
                                {
                                    ...第三级第二项
                                }
                            ]
                        },
                        {
                            ...第二级第二项
                        }
                    ]
                },
                {
    				...第一级第二项
                }
            ]
        }
    ],

style附表

用于定义Picker的样式,这里以行内样式覆写Picker的默认样式,每个属性名对应一个node节点;属性名的值应该是一个style Object,Object的key建议使用javascript 的style属性,比如 { backgroundColor: "red" , zIndex: 100 },这样Picker内部的生成程序可以更好的补全浏览器厂商前缀,当然如果样式属性浏览器支持很好的话,你也完全可以写成 { "background-color": "red" , "z-index": 100 }

| 属性名 | 说明 | | ---------- | -------------------------------------------------------- | | overlay | 覆盖层 overlay: { backgroundColor: 'rgba(0,0,0,0.4)' } | | wrap | 外框 | | headlines | 标题栏 | | title | 标题 | | cancel | 取消 | | confirm | 确定 | | panel | 轮子面板 | | selectline | 选择线 | | mask | 轮子面板覆盖层 |

注意:这里暂不提供轮子、轮子的每一项以及轮子被选中项/激活时的样式编辑,当然如果非常有必要编辑他们的样式也可以通过自定义class来覆写,建议尽量不要覆写轮子每一项的样式,特别是高度,Picker内部html元素的高度是依照轮子每一项的高度计算而来

轮子的样式 class=`${Picker.id}_wheel`

轮子被选中项的样式 class=`${Picker.id}_activated`
