InputGroup 输入组合

把多个 Input / Button / Select / 静态标签拼到一起，共用一组外圆角和边框。

基础用法

InputGroup 是一个纯样式包裹层。把表单控件按顺序放入，相邻的内圆角会被自动去掉，第一个 / 最后一个元素继承外圆角。静态标签用 <span class="cf-input-group__addon"> 渲染。

背景

<script setup lang="ts">
import { ref } from 'vue';
import { CfInputGroup, CfInput } from '@chufix-design/vue';

const search = ref('');
</script>

<template>
  <CfInputGroup>
    <span class="cf-input-group__addon">@</span>
    <CfInput v-model="search" placeholder="username" />
  </CfInputGroup>
</template>

<CfInputGroup>
<span className="cf-input-group__addon">@</span>
<CfInput value={search} onChange={(e) => setSearch(e.target.value)} placeholder="username" />
</CfInputGroup>

与 Select / Button 组合

最常见的「URL 输入框 + 协议选择 + 提交按钮」组合 — 三段拼到一起共享一组边框。

背景

<script setup lang="ts">
import { ref } from 'vue';
import { CfInputGroup, CfInput, CfButton, CfSelect } from '@chufix-design/vue';

const protocol = ref('https');
const host = ref('chufix.com');
const protocols = [
  { label: 'https://', value: 'https' },
  { label: 'http://', value: 'http' },
];
</script>

<template>
  <CfInputGroup>
    <CfSelect v-model="protocol" :options="protocols" />
    <CfInput v-model="host" placeholder="example.com" />
    <CfButton>访问</CfButton>
  </CfInputGroup>
</template>

<CfInputGroup>
<CfSelect value={protocol} onChange={setProtocol} options={protocols} />
<CfInput value={host} onChange={(e) => setHost(e.target.value)} placeholder="example.com" />
<CfButton>访问</CfButton>
</CfInputGroup>

前后静态标签

<span class="cf-input-group__addon"> 可以放在输入框两侧，常见于货币 / URL 路径前缀后缀。

背景

¥RMB

https:///path

<script setup lang="ts">
import { ref } from 'vue';
import { CfInputGroup, CfInput } from '@chufix-design/vue';

const price = ref('');
const url = ref('');
</script>

<template>
  <div class="demo-stack">
    <CfInputGroup>
      <span class="cf-input-group__addon">¥</span>
      <CfInput v-model="price" placeholder="价格" />
      <span class="cf-input-group__addon">RMB</span>
    </CfInputGroup>
    <CfInputGroup>
      <span class="cf-input-group__addon">https://</span>
      <CfInput v-model="url" placeholder="example.com" />
      <span class="cf-input-group__addon">/path</span>
    </CfInputGroup>
  </div>
</template>

<CfInputGroup>
<span className="cf-input-group__addon">¥</span>
<CfInput value={price} onChange={(e) => setPrice(e.target.value)} placeholder="价格" />
<span className="cf-input-group__addon">RMB</span>
</CfInputGroup>

<CfInputGroup>
<span className="cf-input-group__addon">https://</span>
<CfInput value={url} onChange={(e) => setUrl(e.target.value)} placeholder="example.com" />
<span className="cf-input-group__addon">/path</span>
</CfInputGroup>

等宽撑满

stretch 让子元素等宽撑满父容器 — 适合占满表单整行的搜索框 + 提交按钮组合。

背景

<script setup lang="ts">
import { ref } from 'vue';
import { CfInputGroup, CfInput, CfButton } from '@chufix-design/vue';

const q = ref('');
</script>

<template>
  <div style="max-width: 24rem;">
    <CfInputGroup stretch>
      <CfInput v-model="q" placeholder="搜索…" />
      <CfButton variant="primary">搜索</CfButton>
    </CfInputGroup>
  </div>
</template>

<CfInputGroup stretch>
<CfInput value={q} onChange={(e) => setQ(e.target.value)} placeholder="搜索…" />
<CfButton variant="primary">搜索</CfButton>
</CfInputGroup>
