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 🙏

vite-plugin-el-form-submit-prevent

v1.0.1

Published

A Vite plugin that automatically adds @submit.native.prevent to el-form tags in Vue files

Readme

vite-plugin-el-form-submit-prevent

一个自动为 Element UI 的<el-form>标签添加表单提交阻止事 件的 Vite 插件。

🎯  核心功能

自动为 Element UI 的<el-form>标签添加@submit. native.prevent属性,防止表单默认提交行为。

📦  安装

npm install vite-plugin-el-form-submit-prevent --save-dev

或者使用 yarn:

yarn add vite-plugin-el-form-submit-prevent --dev

🚀 使用方法

基础用法

在你的 vite.config.js 中添加插件:

import { defineConfig } from 'vite'
import createAutoElFormPreventPlugin from 
'vite-plugin-el-form-submit-prevent'

export default defineConfig({
  plugins: [
    createAutoElFormPreventPlugin()
  ]
})

高级配置

import { defineConfig } from 'vite'
import createAutoElFormPreventPlugin from 
'vite-plugin-el-form-submit-prevent'

export default defineConfig({
  plugins: [
    createAutoElFormPreventPlugin({
      // 只处理src目录下的vue文件
      include: ['src/**/*.vue'],
      // 排除测试文件和demo文件
      exclude: ['**/*.test.vue', '**/test/**/*.
      vue', '**/demo/**/*.vue'],
      // 启用插件(默认为true)
      enabled: true
    })
  ]
})

使用自定义过滤函数

import { defineConfig } from 'vite'
import createAutoElFormPreventPlugin from 
'vite-plugin-el-form-submit-prevent'

export default defineConfig({
  plugins: [
    createAutoElFormPreventPlugin({
      // 自定义文件过滤逻辑
      filter: (id) => {
        return id.includes('src/components') && 
        !id.includes('test')
      }
    })
  ]
})

📋 功能说明

  1. 目标文件筛选 :只处理 .vue 文件
  2. 智能检测 :扫描代码中的 标签
  3. 自动增强 :为没有 @submit 属性的 标签自动添加 @submit.native.prevent
  4. 避免重复 :如果标签已经有 @submit 属性,则跳过处理

🔧 工作原理

  • 使用正则表达式匹配 el-form 标签
  • 在构建时自动转换代码,无需手动修改每个表单
  • 执行顺序设为 pre ,确保在其他插件之前处理

💡 使用场景

主要用于防止表单的默认提交行为,避免页面刷新,这在单页应用(SPA)中非常重要。

📝 转换示例

转换前:

<el-form :model="form">
  <!-- 表单内容 -->
</el-form>

转换后:

<el-form :model="form" @submit.native.prevent>
  <!-- 表单内容 -->
</el-form>
