代码演示

基础用法

Space 组件会在各个子组件之间设置一定的间距，默认间距为 ​8px​。

<van-space>
  <van-button type="primary">按钮</van-button>
  <van-button type="primary">按钮</van-button>
  <van-button type="primary">按钮</van-button>
  <van-button type="primary">按钮</van-button>
</van-space>

垂直排列

将 ​direction​ 属性设置为 ​vertical​，可以设置垂直方向排列的间距。

<van-space direction="vertical" fill>
  <van-button type="primary" block>按钮</van-button>
  <van-button type="primary" block>按钮</van-button>
  <van-button type="primary" block>按钮</van-button>
</van-space>

自定义间距

通过调整 ​size​ 的值来控制间距的大小。传入 ​number​ 类型时，会默认使用 ​px​ 单位；也可以传入 ​string​ 类型，比如 ​2rem​ 或 ​5vw​ 等带有单位的值。

<!-- 20px -->
<van-space :size="20">
  <van-button type="primary">按钮</van-button>
  <van-button type="primary">按钮</van-button>
  <van-button type="primary">按钮</van-button>
</van-space>

<!-- 2rem -->
<van-space size="2rem">
  <van-button type="primary">按钮</van-button>
  <van-button type="primary">按钮</van-button>
  <van-button type="primary">按钮</van-button>
</van-space>

对齐方式

通过调整 ​align​ 的值来设置子元素的对齐方式, 可选值为 ​start​, ​center​ ,​end​ ,​baseline​，在水平模式下的默认值为 ​center​。

<van-radio-group
  v-model="align"
  direction="horizontal"
  style="margin-bottom: 16px"
>
  <van-radio name="start">start</van-radio>
  <van-radio name="center">center</van-radio>
  <van-radio name="end">end</van-radio>
  <van-radio name="baseline">baseline</van-radio>
</van-radio-group>

<van-space :align="align" style="padding: 16px; background: #f3f2f5">
  <van-button type="primary">{{ align }}</van-button>
  <div style="padding: 40px 20px; background: #fff">Block</div>
</van-space>

import { ref } from "vue";

export default {
  setup() {
    const align = ref("center");
    return { align };
  },
};

自动换行

在水平模式下, 通过 ​wrap​ 属性来控制子元素是否自动换行。

<van-space wrap>
  <van-button type="primary" block>按钮</van-button>
  <van-button type="primary" block>按钮</van-button>
  <van-button type="primary" block>按钮</van-button>
  <van-button type="primary" block>按钮</van-button>
  <van-button type="primary" block>按钮</van-button>
  <van-button type="primary" block>按钮</van-button>
  <van-button type="primary" block>按钮</van-button>
  <van-button type="primary" block>按钮</van-button>
</van-space>
