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 🙏

可视化自定义查询条件

依赖

Vue 2.6.10+、ElementUI 2.10.1+(具体为:Input、Cascader、CascaderPanel、Select、Option、Button、Icon组件)

特点:

  1. 支持增加/删除条件、条件块,并设置连接关系;
  2. 支持根据指标列所选指标动态扩展指标列;
  3. 支持根据指标列所选指标动态设置条件行的比较值可选下拉/级联选项;
  4. 支持获取当前设置的自定义查询条件;
  5. 支持反显查询条件。

效果图

安装

npm install @thtf/vue-query

快速上手

// 安装组件
import CustomQuery from '@thtf/vue-query'

// 引用组件
export default {
  components: {
    CustomQuery
  }
}

// 使用组件
<custom-query
  ref="customQuery"
  :quotaList="quotaList"
  @conditionChange="conditionChange"
/>

属性/方法

1、quotaList 为第一指标列的下拉选项列表;
  格式:[
    {
      label: "",  // 显示值
      value: "", // 选项值,格式可为任意类型
      children:[ // 如果选项有级联下级,若无可省略
        {
          label: "",  // 显示值
          value: "", // 选项值,格式可为任意类型
        }
      ]
    }
  ]

2、@conditionChange 为指标列值发生变化时触发,返回:{context,value}
  context:当前条件行实例
  value:当前选择的指标值

3、新增指标列,context为指标值发生变化时触发方法返回的context
  context.addQuotaColumn([
    {
      label: "",  // 显示值
      value: "", // 选项值,格式可为任意类型
      children:[ // 如果选项有级联下级,若无可省略
        {
          label: "",  // 显示值
          value: "", // 选项值,格式可为任意类型
        }
      ]
    }
  ])

4、设置条件行比较值的下拉可选项,context为指标值发生变化时触发方法返回的context
  context.setCompareOptions([
    {
      label: "",  // 显示值
      value: "", // 选项值,格式可为任意类型
    }
  ],cascaderProps)

  cascaderProps参数可以设置级联下拉属性,具体参考文档最后链接


5、获取当前自定义查询条件
  this.$refs.customQuery.getCustomQuery()

  // 返回数据格式
  {
    connectRelation:"and", // 连接条件 and-且,or-或
    conditions:[
      {  // 条件行格式
        quota: "", // 条件行第一指标列值
        addQuotaArr: [ // 新增指标列数组
          {
            quotaValue:"", // 选择的指标值
            options:[  // 指标选项列表
              {
                label:"", // 显示值
                value:"",  // 下拉选项的值可为任意类型
                children:[ // 如果选项有级联下级,若无可省略
                  {
                    label: "",  // 显示值
                    value: "", // 选项值,格式可为任意类型
                  }
                ]
              }
            ]
          }
        ],
        condition1: "", // 比较条件
        condition2: "", // 截取时比较条件
        startIndex: "", // 从第几位开始截取
        sliceLength: "", // 截取长度
        startValue: "", // 区间起始值
        endValue: "", // 区间截止值
        compareValue: "", // 条件行需要比较的值
        compareSelectValue: [], // 条件行需要比较的值(级联选择的值)
        compareOptions: [ // 条件行需要比较的值的下拉可选项
          {
            label: "",  // 显示值
            value: "", // 选项值,格式可为任意类型
          }
        ]
      },
      { // 条件块格式
        connectRelation:"and",
        conditions:[
          {
            quota: "",
            addQuotaArr: [],
            condition1: "",
            condition2: "",
            startIndex: "",
            sliceLength: "",
            startValue: "",
            endValue: "",
            compareValue: "",
            compareSelectValue: [],
            compareOptions: []
          }
          ...
        ]
      }
      ...
    ]
  }

6、反显自定义查询条件  queryData格式同上`
  this.$refs.customQuery.setCustomQuery(queryData)
  
7、获取自定义查询条件的sql语句(仅限为where子句)
  this.$refs.customQuery.exportSql()
