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 🙏

YtVirtualTransfer 穿梭框列表支持虚拟滚动

基于el-transfer组件的基础上封装的,为了解决 element-ui 中 el-transfer 组件在大数据量的情况下出现的性能问题(数据量太大,导致渲染过慢,或造成页面卡顿) , 同时全选操作迟钝问题。

模拟一万条数据的选择

:::demo

<yt-virtual-transfer-vue3
    v-model="transferValue"
    filterable
    filter-placeholder="请输入"
    :data="items"
/>


<script>
  const createData = (len) => {
    const arr = []
    for (let index = 0; index < len; index++) {
        const obj = { 
            id: index, 
            key: index, 
            label: `labbel ${ index }`,
        }
        arr.push(obj)
    }
    return arr
  }
  export default {
    data(){
      return {
        items: createData(10000),
        transferValue:[],
      }
    }
  }
</script>

:::

特有参数

| 属性 | 说明 | 类型 | 默认值 | |:----------------|:----------------------------------------------------|:------|:----| | data | 接受的下拉框list数组,数组项格式 {value: value的值, label: label的值} | Array | [] | | virtualScroll | 启用虚拟滚动 | Boolean | true |

组件传参、事件

其它跟el-transfer组件一样。
