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 🙏

  el: '#app',
  components: {

  },
  data () {
    return {
      list: [
        {
          value: '1',
          text: 'text1'
        },
        {
          value: '2',
          text: 'text2'
        },
        {

    }
  },
  template: `
    <div id="example">
      <vue-option-list :list="list" :selected="['2', '3']" ref="optionList" @change="onChange"></vue-option-list>
      <div>
        <button @click="selectAll">全选</button>
        <button @click="unselectAll">全不选</button>
        <button @click="selectReverse">反选</button>
        <button @click="getValues">获取所选</button>
      </div>
      <div>
        所选:{{selected}}
      </div>
    </div>
  `,
  methods: {
    onChange: function (val) {
      this.selected = val
    },
    selectAll: function () {
      this.$refs.optionList.selectAll()
    },
    unselectAll: function () {
      this.$refs.optionList.unselectAll()
    },
    selectReverse: function () {
      this.$refs.optionList.selectReverse()
    },
    getValues: function () {
      alert(this.$refs.optionList.getValues())
    }
  }
})

属性

  • list Array 数据列表,每个元素均为对象,其属性有:value(选项的值,必须)、text(选项的描述文字,自定义选项模版时可选,否则必填)。如:[{value: '1', text: 'text1'}, {value: '2', text: 'text2'}]
  • multi Boolean 是否多选,true表示多选(默认), false表示单选
  • selected Array/String 默认选中的选项值,multi为true时传数组,为false时直接传某个选项的值
  • limit Number 最大选项数,默认:0表示不限制,multi为true时有效

slot

您可以自定义选项的模版,此功能用到的作用域插槽,因此需要 Vue >= 2.1.0 详见这里

<vue-option-list :list="list" @change="onChange">
  <template scope="props">
    <span class="text">{{props.item.text}}</span>
  </template>
</vue-option-list>

事件

  • change 选项值发生变化时触发,会带有一个表示选项值参数。multi为true时参数为数组,为false时则为所选选项的值
  • limit 所选选项数量超过limit的限制时触发,会带有一个表示限制选项数的参数。
