## 何时使用

在操作需要较长时间才能完成时，为用户显示该操作的当前进度和状态

## 代码演示

### 如何引入

```jsx import
import { Progress } from '@douyinfe/semi-ui';
```

### 标准的进度条

通过`stroke`属性来控制进度条的填充色  
通过`percent`属性控制已完成的进度  
通过`size`属性控制进度条尺寸  
通过`aria-label`说明进度条具体代表含义  
如果`size`预设的尺寸不满足，可以通过`style`传入 height 自定义进度条高度

```jsx live=true
import React from 'react';
import { Progress } from '@douyinfe/semi-ui';

() => (
    <div style={{ width: 200 }}>
        <Progress percent={10} stroke="#fc8800" aria-label="disk usage" />
        <br />
        <Progress percent={25} stroke="#f93920" aria-label="download progress" />
        <br />
        <Progress percent={50} aria-label="disk usage" />
        <br />
        <Progress percent={80} aria-label="download progress" />
        <br />
        <Progress percent={80} size="large" aria-label="disk usage" />
        <br />
        <Progress percent={80} style={{ height: '8px' }} aria-label="disk usage" />
    </div>
);
```

### 展示百分比文本

通过`showInfo`控制是否展示百分比数字，可以通过`format`格式化展示文本

```jsx live=true
import React from 'react';
import { Progress } from '@douyinfe/semi-ui';

() => (
    <div style={{ width: 200 }}>
        <Progress percent={10} stroke="#fc8800" showInfo={true} aria-label="disk usage" />
        <br />
        <Progress percent={25} stroke="#f93920" showInfo={true} aria-label="disk usage" />
        <br />
        <Progress percent={50} showInfo={true} aria-label="disk usage" />
        <br />
        <Progress percent={50} showInfo={true} format={percent => percent * 10 + '‰'} aria-label="disk usage" />
    </div>
);
```

### 垂直的进度条

设置`direction='vertical'`，展示垂直进度条，可以通过`style`传入 width 控制进度条宽度

```jsx live=true
import React from 'react';
import { Progress } from '@douyinfe/semi-ui';

() => (
    <div style={{ height: 100, display: 'flex' }}>
        <Progress percent={10} direction="vertical" aria-label="disk usage" />
        <Progress percent={25} direction="vertical" aria-label="disk usage" />
        <Progress percent={50} direction="vertical" aria-label="disk usage" />
        <Progress percent={80} direction="vertical" size="large" aria-label="disk usage" />
        <Progress percent={80} direction="vertical" style={{ width: '8px' }} aria-label="disk usage" />
    </div>
);
```

### 环形进度条

将 type 设为`circle`，进度条将会展示成环状。进度条默认尺寸为 72 x 72

```jsx live=true
import React from 'react';
import { Progress } from '@douyinfe/semi-ui';

() => (
    <div>
        <Progress percent={10} type="circle" style={{ margin: 5 }} aria-label="disk usage" />
        <Progress percent={25} type="circle" style={{ margin: 5 }} aria-label="disk usage" />
        <Progress percent={50} type="circle" style={{ margin: 5 }} aria-label="disk usage" />
        <Progress percent={80} type="circle" style={{ margin: 5 }} aria-label="disk usage" />
    </div>
);
```

你可以通过修改`width`来控制环形进度条的大小

```jsx live=true
import React from 'react';
import { Progress } from '@douyinfe/semi-ui';

() => (
    <React.Fragment>
        <div>
            <Progress percent={100} type="circle" width={100} style={{ margin: 5 }} aria-label="disk usage" />
        </div>
        <div>
            <Progress
                percent={100}
                type="circle"
                width={100}
                style={{ margin: 5 }}
                stroke="#f93920"
                aria-label="disk usage"
            />
        </div>
    </React.Fragment>
);
```

### 小号的环形进度条

小号进度条默认尺寸为 24 x 24

```jsx live=true
import React from 'react';
import { Progress } from '@douyinfe/semi-ui';

() => (
    <React.Fragment>
        <Progress percent={10} type="circle" size="small" style={{ margin: 5 }} aria-label="disk usage" />
        <Progress percent={25} type="circle" size="small" style={{ margin: 5 }} aria-label="disk usage" />
        <Progress percent={50} type="circle" size="small" style={{ margin: 5 }} aria-label="disk usage" />
        <Progress percent={80} type="circle" size="small" style={{ margin: 5 }} aria-label="disk usage" />
    </React.Fragment>
);
```

### 动态改变进度

```jsx live=true
import React, { useState } from 'react';
import { Progress, Button } from '@douyinfe/semi-ui';
import { IconChevronLeft, IconChevronRight } from '@douyinfe/semi-icons';

() => {
    const [percent, setPercent] = useState(40);
    return (
        <>
            <div>
                <Progress percent={percent} showInfo aria-label="disk usage" />
                <Button
                    icon={<IconChevronLeft />}
                    theme="light"
                    onClick={() => {
                        setPercent(percent - 10);
                    }}
                    disabled={percent === 0}
                />
                <Button
                    icon={<IconChevronRight />}
                    theme="light"
                    onClick={() => {
                        setPercent(percent + 10);
                    }}
                    disabled={percent >= 100}
                />
            </div>
        </>
    );
};
```

```jsx live=true
import React, { useState } from 'react';
import { Progress, Button } from '@douyinfe/semi-ui';
import { IconChevronLeft, IconChevronRight } from '@douyinfe/semi-icons';

() => {
    const [cirPerc, setCirPerc] = useState(40);
    return (
        <div>
            <div>
                <Progress percent={cirPerc} type="circle" aria-label="disk usage" />
            </div>
            <Button
                icon={<IconChevronLeft />}
                theme="light"
                onClick={() => {
                    setCirPerc(cirPerc - 10);
                }}
                disabled={cirPerc === 0}
            />
            <Button
                icon={<IconChevronRight />}
                theme="light"
                onClick={() => {
                    setCirPerc(cirPerc + 10);
                }}
                disabled={cirPerc >= 100}
            />
        </div>
    );
};
```

### 自定义中心文字内容

你可以通过传入 `format` 函数自定义中心文字，`format` 的入参为当前百分比  
如果不需要中心文本内容，你可以将 `showInfo` 设为 false，或者在 `format` 中直接返回空字符串

```jsx live=true
import React from 'react';
import { Progress } from '@douyinfe/semi-ui';

() => (
    <React.Fragment>
        <Progress
            percent={75}
            showInfo
            type="circle"
            format={per => per + 'Days'}
            style={{ margin: 10 }}
            aria-label="disk usage"
        />
        <Progress
            percent={100}
            showInfo
            type="circle"
            format={per => 'Done'}
            style={{ margin: 10 }}
            aria-label="disk usage"
        />
        <Progress percent={50} type="circle" showInfo={false} style={{ margin: 10 }} aria-label="disk usage" />
    </React.Fragment>
);
```

### 圆角/方角边缘

通过 strokeLinecap 属性，你可以控制环形进度条边缘形状

```jsx live=true
import React from 'react';
import { Progress } from '@douyinfe/semi-ui';

() => (
    <React.Fragment>
        <Progress percent={50} strokeLinecap="round" type="circle" style={{ margin: 10 }} aria-label="disk usage" />
        <Progress percent={50} strokeLinecap="square" type="circle" style={{ margin: 10 }} aria-label="disk usage" />
    </React.Fragment>
);
```

## Accessibility

### ARIA

-   Progress 具有 `progressbar` role 来表示它是一个进度条组件。
-   Progress 会自动将 `aria-valuenow` 设置为传递给组件的进度百分比（`percent`），以确保屏幕阅读器可以获取正确的百分比数值。另外，Progress 支持传入 `aria-valuetext`，当你传入时，根据 W3C 规范，`aria-valuetext` 将优先被屏幕阅读器使用消费，而不是 `aria-valuenow`
-   Progress 支持传入 `aria-label`、`aria-labelledby`
    -   当 Progress 外部存在关于 Progress 作用的描述元素时，你可以通过 aria-labelledby 显式指定某些元素的 id 是 Progress 的标签
    -   否则你应当通过 aria-label 说明 Progress 所代表的具体数值含义

```js
// good case
<p id="progressbar-label">Disk Usage</p>
<Progress aria-labelledby="progressbar-label" percent={80} />

// good case
<Progress aria-label='Percent of disk usage' percent={80} />
<Progress aria-label='Percent of file downloaded' percent={80} />

// usage of aria-valuetext
<Progress aria-label='Percent of disk usage' percent={80} aria-valuetext="Step 2: Copying files... "/> 
```
