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 🙏

Readme

说明

基于@howdyjs/to-drag开发,解决的问题为:父元素下进行拖拽时,tocontrolend等事件的回调参数中坐标不是父控件内的相对位置,而是绝对位置

原控件说明

ToDrag

Version Size

设置Dom可拖动插件

特性

  1. 将fixed元素设为可拖动
  2. 提供不吸附、左右吸附、四方向吸附三种模式
  3. 同时支持PC端和移动端
  4. 封装了vue指令的形式
  5. 新增Absolute模式,控制absolute元素在其父元素盒子下进行拖拽

原生使用

import ToDrag from '@howdyjs/to-drag'
new ToDrag({
  el: '#to-drag', // Selector or Dom
  options: {
    // Your Options
    // 参考下方说明
  }
});

Event

  • todraginit:初始化完成事件
  • todragstart: 拖拽开始事件
  • todragmove:拖拽移动事件
  • todragend:拖拽结束时间

它们都提供以下的回调参数:

  • width:当前拖拽元素的宽
  • height:当前拖拽元素的宽
  • top:当前拖拽元素的上偏移
  • left:当前拖拽元素的左偏移
  • bottom: 当前拖拽元素的下偏移
  • right:当前拖拽元素的右偏移
  • maxX:当前屏幕的宽度(不包含滚动条)
  • maxY:当前屏幕的高度(不包含滚动条)

一般在回调中将位置信息记录到 localstorage,在下一次初始化时填入用户上一次最后移动的信息。

以Vue指令方式使用

import { ToDragDirective } from '@howdyjs/to-drag'
// Vue3全局引入
app.use(ToDragDirective, someGlobalOptions)

// Vue2全局引入(对vue2做了兼容)
Vue.use(ToDragDirective, someGlobalOptions)

// 组件内引入
export default {
  directive: {
    'to-drag': ToDragDirective
  }
}
