Progress进度条

展示操作的当前进度。

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。

• 当一个操作会打断当前界面，或者需要在后台运行，且耗时可能超过 2 秒时；

• 当需要显示一个操作完成的百分比时。

代码演示

进度条

标准的进度条。

import { Progress } from 'antd';
ReactDOM.render(
  <div>
    <Progress percent={30} />
    <Progress percent={50} status="active" />
    <Progress percent={70} status="exception" />
    <Progress percent={100} />
    <Progress percent={50} showInfo={false} />
  </div>,
  mountNode,
);

小型进度条

适合放在较狭窄的区域内。

import { Progress } from 'antd';
ReactDOM.render(
  <div style={{ width: 170 }}>
    <Progress percent={30} size="small" />
    <Progress percent={50} size="small" status="active" />
    <Progress percent={70} size="small" status="exception" />
    <Progress percent={100} size="small" />
  </div>,
  mountNode,
);

进度圈动态展示

会动的进度条才是好进度条。

import { Progress, Button } from 'antd';
const ButtonGroup = Button.Group;
class App extends React.Component {
  state = {
    percent: 0,
  };
  increase = () => {
    let percent = this.state.percent + 10;
    if (percent > 100) {
      percent = 100;
    }
    this.setState({ percent });
  };
  decline = () => {
    let percent = this.state.percent - 10;
    if (percent < 0) {
      percent = 0;
    }
    this.setState({ percent });
  };
  render() {
    return (
      <div>
        <Progress type="circle" percent={this.state.percent} />
        <ButtonGroup>
          <Button onClick={this.decline} icon="minus" />
          <Button onClick={this.increase} icon="plus" />
        </ButtonGroup>
      </div>
    );
  }
}
ReactDOM.render(<App />, mountNode);

自定义文字格式

format 属性指定格式。

import { Progress } from 'antd';
ReactDOM.render(
  <div>
    <Progress type="circle" percent={75} format={percent => `${percent} Days`} />
    <Progress type="circle" percent={100} format={() => 'Done'} />
  </div>,
  mountNode,
);

分段进度条

标准的进度条。

import { Tooltip, Progress } from 'antd';
ReactDOM.render(
  <div>
    <Tooltip title="3 done / 3 in progress / 4 to do">
      <Progress percent={60} successPercent={30} />
    </Tooltip>
    <Tooltip title="3 done / 3 in progress / 4 to do">
      <Progress percent={60} successPercent={30} type="circle" />
    </Tooltip>
    <Tooltip title="3 done / 3 in progress / 4 to do">
      <Progress percent={60} successPercent={30} type="dashboard" />
    </Tooltip>
  </div>,
  mountNode,
);

自定义进度条渐变色

linear-gradient 的封装。推荐只传两种颜色。

import { Progress } from 'antd';
const Demo = () => (
  <div>
    <Progress
      strokeColor={{
        '0%': '#108ee9',
        '100%': '#87d068',
      }}
      percent={99.9}
    />
    <Progress
      strokeColor={{
        from: '#108ee9',
        to: '#87d068',
      }}
      percent={99.9}
      status="active"
    />
  </div>
);
ReactDOM.render(<Demo />, mountNode);

进度圈

圈形的进度。

import { Progress } from 'antd';
ReactDOM.render(
  <div>
    <Progress type="circle" percent={75} />
    <Progress type="circle" percent={70} status="exception" />
    <Progress type="circle" percent={100} />
  </div>,
  mountNode,
);

小型进度圈

小一号的圈形进度。

import { Progress } from 'antd';
ReactDOM.render(
  <div>
    <Progress type="circle" percent={30} width={80} />
    <Progress type="circle" percent={70} width={80} status="exception" />
    <Progress type="circle" percent={100} width={80} />
  </div>,
  mountNode,
);

动态展示

会动的进度条才是好进度条。

import { Progress, Button } from 'antd';
const ButtonGroup = Button.Group;
class App extends React.Component {
  state = {
    percent: 0,
  };
  increase = () => {
    let percent = this.state.percent + 10;
    if (percent > 100) {
      percent = 100;
    }
    this.setState({ percent });
  };
  decline = () => {
    let percent = this.state.percent - 10;
    if (percent < 0) {
      percent = 0;
    }
    this.setState({ percent });
  };
  render() {
    return (
      <div>
        <Progress percent={this.state.percent} />
        <ButtonGroup>
          <Button onClick={this.decline} icon="minus" />
          <Button onClick={this.increase} icon="plus" />
        </ButtonGroup>
      </div>
    );
  }
}
ReactDOM.render(<App />, mountNode);

仪表盘

通过设置 type=dashboard，可以很方便地实现仪表盘样式的进度条。

import { Progress } from 'antd';
ReactDOM.render(<Progress type="dashboard" percent={75} />, mountNode);

圆角/方角边缘

通过设定 strokeLinecap="square|round" 可以调整进度条边缘的形状。

import { Progress } from 'antd';
ReactDOM.render(
  <div>
    <Progress strokeLinecap="square" percent={75} />
    <Progress strokeLinecap="square" type="circle" percent={75} />
    <Progress strokeLinecap="square" type="dashboard" percent={75} />
  </div>,
  mountNode,
);

API

各类型共用的属性。

type="line"

type="circle"

type="dashboard"
