vue.js - 您如何在 vue-select 中使用自定义插槽的默认/初始选择选项？

Question

我不确定如何使用 vue-select 设置默认/初始选定选项，特别是在使用插槽时。

这是代码：https ://vue-select.org/guide/slots.html

我希望其中一个选项最初显示在页面加载时。

将您想要的选项对象作为默认值传递到组件的 v-model 属性中。

Vue.component('v-select', VueSelect.VueSelect)

new Vue({
  el: '#app',
  data: {
    selectedOption: {
          title: 'Read the Docs',
          icon: 'fa-book',
          url: 'https://codeclimate.com/github/sagalbot/vue-select'
    },
    options: [
      {
          title: 'Read the Docs',
          icon: 'fa-book',
          url: 'https://codeclimate.com/github/sagalbot/vue-select'
        },
        {
          title: 'View on GitHub',
          icon: 'fa-github',
          url: 'https://codeclimate.com/github/sagalbot/vue-select'
        },
        {
          title: 'View on NPM',
          icon: 'fa-database',
          url: 'https://codeclimate.com/github/sagalbot/vue-select'
        },
        {
          title: 'View Codepen Examples',
          icon: 'fa-pencil',
          url: 'https://codeclimate.com/github/sagalbot/vue-select'
        }
    ]
  }
})
