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 🙏

简介

写JSON创建form (适用于ElementPlus + TypeScript + Vue3)

安装

npm i element-form-render

使用

  1. 首先在您的项目全局的 main.ts 中设置表单生成器axios的baseURL(主要是避免每个页面都设置)
import {setAxiosConfig} from "element-form-render/src";
setAxiosConfig({
    timeout: 50000,
    baseURL: "https://domain.com", // 如果想在表单组件使用相对URL,需要设置 baseURL
    headers: { // 根据自己的需求设置headers,如无特殊需求可不设置
        "Authorization": "token",
        "Content-Type": "application/json"
    }
});
  1. 通过本组件约定的结构定义编写JSON结构,创建表单
<template>
  <div>
    <form-render :json="json" @on-submit="handleSubmit" />
  </div>
</template>
<script setup lang="ts">
// 您可以从"element-form-render/src" 中引入本组件所有的组件、类型、类库和函数
import {FormRender} from "element-form-render/src";
import type {FormStructure} from "element-form-render/src/types";
import {reactive} from "vue";
const json = reactive<FormStructure>({
    type: "create",
    name: "test",
    title: "title", //设置为空则不显示标题
    api: "/api/form/create",// 不设置的话可以使用 @on-submit 获取表单提交的数据
    elements : [// 二维数组进行布局,第一维是行 每一行内可以放置多个组件(注意:使用了Element的24等分格,注意个数适配)
        [
            {
              type:"input",
              name:"title",
              label:"网站名称",
              validator:["required"]
            },
        ],
        [
            {
                type:"input",
                name:"website",
                label:"网站网址",
                width:"300px",
                prefix:"https://www",
                suffix:".com",
                validator:["required"]
            }
       ],
       [
            {
              type:"radio",
              name:"type",
              label:"网站类型",
              source:{
                type:"static",
                 options:[
                     {label:"门户站", value:"portal"},
                     {label:"资源站", value:"source"}
                 ]
              }
            },
            {
                type: "checkbox",
                name: "tags",
                label: "网站类型",
                source: {
                    type: "ajax",
                    options: {
                      api: "/api/dict",
                      params: {section: "site_tag"},
                      labelField: "name",
                      valueField: "id"
                    }
                }
            },
        ]
    ]
});

// 当表单 api 不设置时 定义获取数据的函数
const handleSubmit = (data) => {
    console.log(data);
}
</script>
<style scoped>
</style>
  1. FormStructure 类型定义
export type FormStructure = {
    type: 'create' | 'update' | 'customer',// 当值为”update“时,表单将会自动请求api获取需要修改的数据
    name: string,
    title: string,
    elements: FormElementField[][], // 字段布局
    api?: string,// 表单数据提交URL
    primary_key?: string, // 修改数据时数据主键名
    primary_value?: string|number,// 修改数据时数据主键值
    config?: { // 表单设置项
        labelWidth?: number,
        labelPosition?: 'left' | 'right' | 'top',
        showSubmit?: boolean,
        submitText?: string,
        showReset?: boolean,
        resetText?: string,
    },
    dynamicData?: Record<string, any>,// 当使用自定义字段组件时,可以通过该对象写数据
    appendData?: Record<string, any>
}
