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 🙏

## npm 安装

Readme

vue2-virtual-tree

npm 安装

npm install vue2-virtual-tree

yarn 安装

yarn add vue2-virtual-tree

使用

import VirtualTree from 'vue2-virtual-tree'
import 'vue2-virtual-tree/lib/vue2-virtual-tree.css'

Vue.use(VirtualTree)
<virtual-tree
  :data="data"
  :props="props"
  @node-click="handleNodeClick"
  @checked="handleChecked"
  ref="tree"
>
</virtual-tree>

<script>
  export default {
    data() {
      return {
        props: {
          children: 'TestChildren',
          label: 'Label',
          key: 'uuid',
        },
      }
    },
  }
</script>

因为虚拟树需要通过滚动视口确定区域, 所以初始化时virtual-tree所占的 DOM 必须有高度, 这个高度可以是由父级设置的.

可以为每行数据定义插槽

<virtual-tree
  :data="data"
  :props="props"
  @node-click="handleNodeClick"
  @checked="handleChecked"
>
  <template #default="{ text, parentName }">
    <div class="test-slot">{{ text }} {{ parentName }}</div>
  </template>
</virtual-tree>

默认插槽中会注入当前节点的数据, parentName是自动生成的一个关联父级字段, 类似面包屑这样的字符串

全部 > 节点1 > 字节2

点击对应节点的时候,会把添加一个active的 className, 你可以自己设置样式来定义点击时的效果

.treeitem_content_label.active {
}

API
