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 🙏

vue-enum

前端常量 枚举工具

目前vue-enum2.0为适配vue3.0的版本,如需vue2.x的项目使用,请安装1.05版本

一、安装及初始化方法

1. npm install vue-enum --save
2. 按以下格式定义您的枚举对象

let enumInfo = {
    SOURCE_IN_TYPE: {
        PURCHASE_IN: {
            value: 1,
            desc: '采购入库'
        },
        REFUND_IN: {
            value: 2,
            desc: '退货入库'
        },
        CHECK_IN: {
            value: 3,
            desc: '盘点入库'
        },
        CONFIRM_IN: {
            value: 4,
            desc: '取消订单入库'
        }
    }
}
3.import App from './App.vue'
4. import Enum from 'vue-enum'
5.const app = createApp(App)
6.app.use(Enum,{enumInfo})

二、使用方法

目前插件提供四个方法

可在全局使用this.$enum.getDescByValue() 、this.$enum.getValueDescList() 、this.$enum.getValueDesc() this.$enum.isDependConstant() 调用

也可在inject中主动声明调用 inject: ['constantInfo','$enum'] this.$enum.getDescByValue() .....

根据枚举值获取描述 示例:

在表格渲染时经常遇到需要将状态转换成描述的情况,此时可以使用

params.row.sourceType=1
this.$enum.getDescByValue('SOURCE_IN_TYPE', params.row.sourceType)) //采购入库

下拉菜单经常需要使用键值对来渲染select的option [{value:desc}]

let sourceTypeList =this.$enum.getValueDescList('SOURCE_IN_TYPE')  
//[    
    {value: 1, desc: "采购入库"},
    {value: 2, desc: "退货入库"},
    {value: 3, desc: "盘点入库"},
    {value: 4, desc: "取消订单入库"}
   ]

   <Select>
       <Option
           v-for="(item,index) in sourceTypeList"
           :value="item.value"
           :key="index"
       >{{item.desc}}</Option>
   </Select>
 

根据枚举名获取对应的value描述键值对{value:desc}

this.$enum.getValueDesc('SOURCE_IN_TYPE')
//
{
    1:"采购入库",
    2:"退货入库",
    3:"盘点入库",
    4:"取消订单入库"
}

根据枚举名及描述判断枚举值是否与目标值相等 Boolean

this.$enum.isDependConstant('SOURCE_IN_TYPE','PURCHASE_IN',1)

//
true
