当我尝试在 vue3 打字稿中执行内联三元运算符时，出现“布尔类型上不存在属性类型”错误

Question

错误Property type does not exist on type boolean显示在 show.value boolean

当我尝试根据真实性为图标应用文本时

<template>

<div class="d-flex cursor-pointer justify-content-between border rounded bg-white mt-4 p-2 w-100 " @click="dropdown">
    <span>Purchase Requsition</span>
    <span class="material-icons fs-28 text-primary">
{{show.value ? 'arrow_circle_down' : 'arrow_circle_down' }}     </span>
</div>

</template>

<script setup lang="ts">
import { ref } from "vue";

const show = ref<boolean>(false)

function dropdown(){
   show.value = !show.value
}
</script>

<style scoped>

</style>

Answer 1

您应该在模板中使用show而不是show.value 。 show.value仅在组合 API 的script标记中可用。

<template>

<div class="d-flex cursor-pointer justify-content-between border rounded bg-white mt-4 p-2 w-100 " @click="dropdown">
    <span>Purchase Requsition</span>
    <span class="material-icons fs-28 text-primary">
      {{show ? 'arrow_circle_down' : 'arrow_circle_down' }}
    </span>
</div>

</template>
