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 🙏

概述

该组件是在element cascader组件上进行修改的,增加了一些功能以及修改了一些特性:

增加的功能

  • 多选功能。 多选功能下, 值默认并不在输入框展示, 如果要展示值, 请将show-values选项置为true。(PS:只能在expand-trigger值为"hover"时启动该功能,因为若在click时启动,那么点击操作将会有展开下一级菜单和选中该菜单两个命令,这也意味着选中子菜单的值时父菜单必定是选中的,这是不合理的)

  • 能够指定菜单弹出框(.el-cascader-menus)被追加到哪个元素后面。需要将append-to-body置为false,然后指定append-el的选择器。

    ​```
    <el-cascader-modified v-model="val"
        :options="options"
        :append-to-body="false"
        append-el="#app"></el-cascader-modified>
    ​```

修改的特性

  • 如果能够选择任何一级的选项, 那么父级菜单的disabled属性为true, 那么依然能够显示子菜单。 (原先是不能的)
  • 在expand-trigger为hover时, 必须点击选项才能选中值。 (原先是hover上去就会选中值, 导致体验不好)

使用方式

示例

<template>
  <el-cascader-modified
    :options="options"
    :show-all-levels="false"
    expand-trigger="hover"
    change-on-select
    v-model="val"
    multiple
    clearable
    filterable
    show-values
  ></el-cascader-modified>
</template>
<script>
    import Cascader from 'element-cascader-modified';
    import  'element-cascader-modified/dist/static/css/index.css';
    Vue.component(Cascader.name, Cascader);
</script>
