Progress Bar

<p-progress-bar> | PProgressBar
Since 1.0 stable

Progress bars are used to show the status of an ongoing operation.

<p-progress-bar value="50"></p-progress-bar>

import PProgressBar from 'pure-uikit/dist/react/progress-bar';

const App = () => <PProgressBar value={50} />;

Examples

Labels

Use the label attribute to label the progress bar and tell assistive devices how to announce it. 

<p-progress-bar value="50" label="Upload progress"></p-progress-bar>

import PProgressBar from 'pure-uikit/dist/react/progress-bar';

const App = () => <PProgressBar value="50" label="Upload progress" />;

Custom Height

Use the --height custom property to set the progress bar’s height.

<p-progress-bar value="50" style="--height: 6px;"></p-progress-bar>

import PProgressBar from 'pure-uikit/dist/react/progress-bar';

const App = () => <PProgressBar value={50} style={{ '--height': '6px' }} />;

Showing Values

Use the default slot to show a value.

50% 
<p-progress-bar value="50" class="progress-bar-values">50%</p-progress-bar>

<br />

<p-button circle><p-icon name="dash" label="Decrease"></p-icon></p-button>
<p-button circle><p-icon name="plus" label="Increase"></p-icon></p-button>

<script>
  const progressBar = document.querySelector('.progress-bar-values');
  const subtractButton = progressBar.nextElementSibling.nextElementSibling;
  const addButton = subtractButton.nextElementSibling;

  addButton.addEventListener('click', () => {
    const value = Math.min(100, progressBar.value + 10);
    progressBar.value = value;
    progressBar.textContent = `${value}%`;
  });

  subtractButton.addEventListener('click', () => {
    const value = Math.max(0, progressBar.value - 10);
    progressBar.value = value;
    progressBar.textContent = `${value}%`;
  });
</script>

import { useState } from 'react';
import PButton from 'pure-uikit/dist/react/button';
import PIcon from 'pure-uikit/dist/react/icon';
import PProgressBar from 'pure-uikit/dist/react/progress-bar';

const App = () => {
  const [value, setValue] = useState(50);

  function adjustValue(amount) {
    let newValue = value + amount;
    if (newValue < 0) newValue = 0;
    if (newValue > 100) newValue = 100;
    setValue(newValue);
  }

  return (
    <>
      <PProgressBar value={value}>{value}%</PProgressBar>

      <br />

      <PButton circle onClick={() => adjustValue(-10)}>
        <PIcon name="dash" label="Decrease" />
      </PButton>

      <PButton circle onClick={() => adjustValue(10)}>
        <PIcon name="plus" label="Increase" />
      </PButton>
    </>
  );
};

Indeterminate

The indeterminate attribute can be used to inform the user that the operation is pending, but its status cannot currently be determined. In this state, value is ignored and the label, if present, will not be shown. 

<p-progress-bar indeterminate></p-progress-bar>

import PProgressBar from 'pure-uikit/dist/react/progress-bar';

const App = () => <PProgressBar indeterminate />;
