我刚刚开始使用 VueJS 和 Tailwind,之前从未真正使用过任何与 npm 相关的东西。
我有下面的代码,使用 Tailwind 和 Headless UI,通过调试,我知道我喜欢 99% 的方式......除了持续的错误消息
未捕获的 ReferenceError:未定义帖子
我知道这应该是直截了当的,但是我在这里或通过 Google 找到的一切都没有奏效。我哪里错了?
<template>
<Listbox as="div" v-model="selected">
<ListboxLabel class="">
Country
</ListboxLabel>
<div class="mt-1 relative">
<ListboxButton class="">
<span class="">
<img :src="selected.flag" alt="" class="" />
<span class="">{{ selected.name }}</span>
</span>
<span class="">
<SelectorIcon class="" aria-hidden="true" />
</span>
</ListboxButton>
<transition leave-active-class="" leave-from-class="opacity-100" leave-to-class="opacity-0">
<ListboxOptions class="">
<ListboxOption as="template" v-for="country in posts" :key="country" :value="country" v-slot="{ active, selected }">
<li :class="">
<div class="">
<img :src="country.flag" alt="" class="" />
<span :class="[selected ? 'font-semibold' : 'font-normal', 'ml-3 block truncate']">
{{ country.latin }}
</span>
</div>
<span v-if="selected" :class="">
<CheckIcon class="" aria-hidden="true" />
</span>
</li>
</ListboxOption>
</ListboxOptions>
</transition>
</div>
</Listbox>
</template>
<script>
import { ref } from 'vue'
import { Listbox, ListboxButton, ListboxLabel, ListboxOption, ListboxOptions } from '@headlessui/vue'
import { CheckIcon, SelectorIcon } from '@heroicons/vue/solid'
import axios from 'axios'
export default {
data() {
return {
response: null,
posts: undefined,
};
},
components: {
Listbox,
ListboxButton,
ListboxLabel,
ListboxOption,
ListboxOptions,
CheckIcon,
SelectorIcon,
},
mounted: function() {
axios.get('http://localhost')
.then(response => {
this.posts = response.data;
});
},
setup() {
const selected = ref(posts[30])
return {
selected,
}
},
}
</script>
违规行是const selected = ref(posts[30])
我知道我需要以某种方式定义posts
,但我不明白怎么做?
