从 v-select 获取值
Get value from v-select
我有一个下拉组件，它利用 vue-select 将状态填充为下拉列表。当我从下拉列表中选择一个选项时，数据没有被抓取。这是我的下拉组件。

当我 select 一个状态时，我没有得到那个值。谁能告诉我哪里做错了。
您在 v-select 上没有 v-model，并且您的自定义组件 StatesDropdown 未实现 v-model contract for custom components
它应该是这样的：
<!-- StatesDropdown.vue -->
<script>
export default {
props: ['modelValue'],
emits: ['update:modelValue'],
data() {
// .....
},
computed: {
model: {
get() { return this.modelValue },
set(newValue) { this.$emit('update:modelValue', newValue) }
}
}
}
</script>
<template>
<div>
<label>States</label>
<v-select label="name" :options="states" v-model="model">
</v-select>
</div>
</template>
您需要更新一些内容并 emit 更改 v-select 的事件。
这是更新
<template>
<div>
<label>States</label>
<v-container fluid>
<v-select
label="name"
:items="states"
item-text="name"
item-value="code"
@change="$emit('input', $event)"
