<div class="form-wrapper">
<form @submit.prevent="submitForm">
<div class="form-item">
<label>类型：</label>
<select v-model="formData.type">
<option value="income">收入</option>
<option value="outcome">支出</option>
</select>
</div>
<div class="form-item">
<label>金额：</label>
<input type="number" v-model="formData.amount" />
</div>
<div class="form-item">
<label>日期：</label>
<input type="date" v-model="formData.date" />
</div>
<button type="submit">记一笔</button>
</form>
</div>
</template>

<style scoped>
.form-wrapper {
max-width: 400px;
margin: 0 auto;
}

.form-item {
margin-bottom: 20px;
}

label {
display: inline-block;
width: 60px;
text-align: right;
margin-right: 10px;
}
</style>

<script setup>
import { ref } from 'vue';

const formData = ref({
type: '',
amount: '',
date: new Date(),
});

function submitForm() {
// 提交表单
console.log(formData.value);
}
</script>

在上面的代码中，我添加了一个 "form-wrapper" 的 div 包裹整个表单，用于设置表单最大宽度和居中对齐。我还添加了一个 "form-item" 的 div 包裹每个表单项，用于设置表单项之间的间距。最后，我添加了一些基本的样式用于对齐和布局。
