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 🙏

dc-vant-form

author: DCodes-wangfan

说明

1、在使用前需要保证项目中安装了vant

2、在使用表单之前,你需要准备表单渲染的数据,以及当前用作回显的详情数据。

3、该表单提供了9种输入组件,分别为:文本、小数、整数、级联选择器、文本域、数字间隔输入器、标准时间选择器、年月日时间选择器、年月时间选择器。

4、初始化时配置参数必传,表单可传可不传,若只传配置参数,我们会根据配置参数自动生成表单。

5、表单提供编辑回显、单条数据传入回显。

6、通过getInit函数初始化表单,通过submit函数获取表单结果。

开始

npm i dc-vant-form

自定义表单示例:

初始化

在初始化前,需要先定义初始化配置,配置项如下:

| key | 说明 | | ---------- | ------------------------------------------------------------ | | label | 表单label | | module | 表单绑定的数据key | | type | 表单组件类型,值对应:1文本、2小数、3整数、4级联选择器、5文本域、6时间选择器、7数字间隔输入器 | | isRequired | 是否星号校验,值对应:true、false | | options | 表单下拉菜单项,值对应数组对象:[{label: '红色',value: 'red'}] | | dateType | 时间选择器类型,默认标准时间选择器,值对应:datetime标准时间、date年月日、year-month年月 |

注意点

| 类型 | 说明 | | ------- | ------------------------------------------------------------ | | type: 4 | 必须配置options项,你可以给它默认值空数组[] | | type: 6 | 必须配置dateType项,你可以选择三种对应值:datetime、date、year-month | | type: 7 | 必须配置 beginModule、endModule,分别对应左侧、右侧输入框;type为7不需要配置module项 |

下面是示例:

"usingComponents": {
    "dc-vant-form": "/miniprogram_npm/dc-vant-form/dc-vant-form/index"
  }

页面:

<dc-vant-form id="dc-vant-form" />

配置项:

        type: 2,
        isRequired: false
      },

            id: 2,
            label: '组装',

        endModule: 'endLimit',
        type: 7,
        isRequired: false

        isRequired: false
      },
      {
        label: '创建时间',
        module: 'createDate',

      {
        label: '标准时间',
        module: 'createDate2',

        dateType: 'year-month',
        isRequired: true
      },
      {
        label: '备注',
        module: 'remark',
        type: 5,
        isRequired: false
      }
    ]

我们将上面的配置项传入init函数初始化表单

  // 数据初始化
  init() {
    let dom = this.selectComponent("#dc-vant-form");
    dom.getInit(this.data.config)
  },
      
  onLoad(options) {
    this.init();
  },

获取表单数据

我们通过submit函数获取表单数据

  // 提交
  sure() {
    let dom = this.selectComponent("#dc-vant-form");
    console.log(dom.submit());
  }

表单回显

在初始化时,可以传入表单详情,我们会根据配置项回显表单数据。

// 表单详情数据
form: {
  address: '浙江省杭州市',
  goodsType: 101,
  goodsColor: 'red',
  packingVolume: 10,
  goodsWeight: 5,
  goodsStructure: 2230,
  goodsNumber: 100,
  beginLimit: 1,
  endLimit: 10,
  contact: 'DCodes',
  createDate: '2023-01-01',
  createDate2: '2023-01-01 20:00:00',
  createDate3: '2023-01',
  remark: '这是一个动态的文本域'
}
init() {
  let { config,form } = this.data;
  let dom = this.selectComponent("#dc-vant-form");
  dom.getInit(config, form)
},

onLoad(options) {
  this.init();
},

单项数据修改

我们提供onAccept函数,用于接收指定表单项的修改

onAccept接收三个参数,依次为:value、key、place

| 参数 | 说明 | | ----- | ------------------------------------------------------------ | | value | 更改的值 | | key | 表单中对应的key | | place | 如果是数字间隔修改器,需要传入place,分为两个固定参数:left、right,表示需要修改间隔输入框的左侧和右侧 |

bandicam 2023-11-16 16-14-16-944 00_00_00-00_00_30~1

// 修改某项
update() {
    let dom = this.selectComponent("#dc-vant-form");
    // 普通类型
    // dom.onAccept('浙江省杭州市', 'address')
    
    // 级联选择器-value为options中的key
    // dom.onAccept(103, 'goodsType')
    
    // 数字间隔输入器
    // dom.onAccept(1, 'beginLimit', 'left')
    // dom.onAccept(3, 'endLimit', 'right')
 }
