## Space 间距
|
|
|
|
虽然我们拥有 [Divider 组件](#/zh-CN/component/divider), 但很多时候我们需要不是一个被 [Divider 组件](#/zh-CN/component/divider) 分割开的页面结构, 因此我们会重复的使用很多的 [Divider 组件](#/zh-CN/component/divider), 这在我们的开发效率上造成了一定的困扰, **间距组件**就是为了解决这种困扰应运而生的.
|
|
|
|
|
|
|
|
### 基础用法
|
|
|
|
最基础的用法, 通过这个组件来给组件之间提供统一的间距
|
|
|
|
|
|
|
|
:::demo 通过间距组件来给多个组件之间提供间距
|
|
|
|
|
|
|
|
```html
|
|
|
|
<template>
|
|
|
|
<el-space wrap>
|
|
|
|
<el-card class="box-card" style="width: 250px" v-for="i in 3" :key="i">
|
|
|
|
<template #header>
|
2021-02-01 14:48:26 +08:00
|
|
|
<div class="card-header">
|
2020-12-18 10:30:26 +08:00
|
|
|
<span>Card name</span>
|
2021-02-01 14:48:26 +08:00
|
|
|
<el-button class="button" type="text">Operation button</el-button>
|
2020-12-18 10:30:26 +08:00
|
|
|
</div>
|
|
|
|
</template>
|
|
|
|
<div v-for="o in 4" :key="o" class="text item">
|
|
|
|
{{ 'List item ' + o }}
|
|
|
|
</div>
|
|
|
|
</el-card>
|
|
|
|
</el-space>
|
|
|
|
</template>
|
|
|
|
```
|
|
|
|
:::
|
|
|
|
|
|
|
|
### 垂直布局
|
|
|
|
使用 `direction` 来控制布局的方式, 背后实际上是利用了 `flex-direction` 来控制.
|
|
|
|
|
|
|
|
:::demo 当然也提供垂直布局的方式
|
|
|
|
|
|
|
|
```html
|
|
|
|
<template>
|
|
|
|
<el-space direction="vertical">
|
|
|
|
<el-card class="box-card" style="width: 250px" v-for="i in 2" :key="i">
|
|
|
|
<template #header>
|
2021-02-01 14:48:26 +08:00
|
|
|
<div class="card-header">
|
2020-12-18 10:30:26 +08:00
|
|
|
<span>Card name</span>
|
2021-02-01 14:48:26 +08:00
|
|
|
<el-button class="button" type="text">Operation button</el-button>
|

|
|
</div>
|
|
|
|
</template>
|
|
|
|
<div v-for="o in 4" :key="o" class="text item">
|
|
|
|
{{ 'List item ' + o }}
|
|
|
|
</div>
|
|
|
|
</el-card>
|
|
|
|
</el-space>
|
|
|
|
</template>
|
|
|
|
```
|
|
|
|
|
|
|
|
:::
|
|
|
|

|
### 控制间距的大小
|
|
|
|
通过调整 `size` 的值来控制间距的大小
|
|
|
|
|
2020-12-18 18:05:14 +08:00
|
|
|
可供选择的内建的值有 `mini`, `small`, `medium`, `large`, 分别对应 `4px`, `8px`, `12px`, `16px`. 默认的间距大小为 `small` 也就是 `8px`
|
2020-12-18 10:30:26 +08:00
|
|
|
|
|
|
|
您也可以通过自定义的 `size` 来控制大小,详见下一部分
|
|
|
|
:::demo 使用 `size` 属性控制大小

|
|
|
|
|
|
|

### 自定义 Size
|
2020-12-18 18:05:14 +08:00
|
|
|
很多时候, 内建的大小不满足设计师的要求, 我们可以通过传入自己定义的大小 (数字类型) 来设置
|
2020-12-18 10:30:26 +08:00
|
|
|
|
|
|
|
:::demo
|
|
|
|
```html
|
|
|
|
<template>
|
|
|
|
<el-slider v-model="size" />
|
|
|
|
<el-space wrap :size="size">
|
|
|
|
<el-card class="box-card" style="width: 250px" v-for="i in 2" :key="i">
|
|
|
|
<template #header>
|

|
|
|
<div class="card-header">

|
```
|
|
|
|
:::
|
|
|
|
|
|
|
|
:::tip
|
|
|
|
不要与使用依赖父元素百分比宽度 (高度) 的元素一起使用, 例如 `ElSlider`, 这样会造成光标不同步
|
|
|
|
:::
|
|
|
|
|
|
|
|
### 自动换行
|
|
|
|
在**水平 (horizontal)** 模式下,通过控制 `wrap` **(布尔类型)** 来控制是否自动换行
|
|
|
|
|
|
|
|
:::demo 利用 `wrap` 控制换行
|
|
|
|
|
|
|
|
```html
|
|
|
|
<el-space wrap>
|
|
|
|
<div v-for="i in 20" :key="i">
|
|
|
|
<el-button type="text">
|
|
|
|
文字按钮
|
|
|
|
</el-button>
|
|
|
|
</div>
|
|
|
|
</el-space>
|
|
|
|
```
|
|
|
|
:::
|
|
|
|
|
|
|
|
### 行间分隔符
|
|
|
|
有时候, 仅仅在行间加空白, 并不能满足我们的日常需求, 此时分隔符 (spacer) 就可以发挥非常好的作用了.
|
|
|
|
|
|
|
|
#### 字符串 或 数字类型的分隔符

### 对齐方式
|
|
|
|
设置该值可以调整所有子节点在容器内的对齐方式, 可设置的值与 [align-items](https://developer.mozilla.org/zh-CN/docs/Web/CSS/align-items) 一致

### 自动填充容器
|
|
|
|
|
|
|
|
通过 `fill` **(布尔类型)** 参数可以控制子节点是否自动填充容器
|
|
|
|
|
|
|
|
下面的例子中,当设置为 `fill` 时,子节点的宽度会自动适配容器的宽度
|
|
|
|
|
|
|
|
:::demo 用 fill 让子节点自动填充容器
|
|
|
|
|
|
|
|
