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 🙏

auto-loading-directive

v0.0.8

Published

一个 vue3的 点击事件防重指令

Downloads

5

Readme

安装

# npm
npm i auto-loading-directive
# pnpm
pnpm add auto-loading-directive

使用

// 在 main.js 中引入并使用
import { autoLoadingDirective } from 'auto-loading-directive'

autoLoadingDirective(app: App, directiveName?: string)

所有组件、原生按钮以及标签等都可以使用此指令进行点击防重

<!-- 组件内 -->
<script setup lang='ts'>
function handleClick(e: MouseEvent): Promise<boolean>{
	return api.request().then(response => {
		...something
		// 无返回值或返回值不为 false 结束防重
	})
}
function handleClick(e: MouseEvent): boolean {
	...something
		// 无返回值或返回值不为 false 结束防重
	return true
}
async function asyncFunc() {
	await ...something
	// 无返回值或返回值不为 false 结束防重
}
function handleClick(e: MouseEvent, callback: () => void): void {
	...something
	// 调用回调函数结束防重
	callback()
}
function modifiersCallback(e: MouseEvent, callback: () => void): void {
	...something
	// 此时返回 false 无法结束防重
	return false
	// 只能通过回调函数的形式来停止防重
	callback()
} 
</script>
<template>
	<!-- element-plus -->
	<el-button v-auto-loading="handleClick">提交</el-button>
	<!-- naive-ui -->
	<n-button v-auto-loading="handleClick">提交</n-button>
	<!-- 自定义按钮 -->
	<custom-button v-auto-loading="handleClick">提交</custom-button>
	<!-- 原生按钮 -->
	<button v-auto-loading="handleClick">提交</button>
	<!-- input 按钮 -->
	<input v-auto-loading="handleClick" type="button" value="提交"	/>
	<!-- 标签 -->
	<div v-auto-loading="handleClick">提交</div>
	<!-- modifiers -->
	<el-button v-auto-loading.callback="modifiersCallback">提交</el-button>
</template>

自定义组件

  • 当使用自定义组件时,组件需实现 disabled/loading 逻辑,同时需提供 disabled/loading 任其一 props,以供指令使用

自动防重

  • 指令会根据传入函数的返回值以及回调函数来自动停止防重
  • 如果返回值不为 true, 或者 Promise.resolve() 不为 true,则需要自行调用回调函数来停止防重

modifiers: callback

  • 当使用 modifiers: callback 时, 只能通过回调函数来结束防重
  • modifiers 优先级最高, 使用 modifiers 时, 返回 false 无法结束防重

当使用该指令时,原始 click 事件将无法触发
