当它超过100％时，径向进展

Question

我需要帮助调整我的进度径向代码，以便进度条停止在100％而不会超过导致间隙。

进步辐射的代码。任何在这里将不胜感激。这就是gap.qazxsw poi的样子

它看起来像渐变再次越过圆圈。

Answer 1

如果进度不应超过100％，则将其限制在100％。

在

class ProgressRadial extends Component {
static propTypes = {
    /** Width of the stroke */
    strokeWidth: PropTypes.number,
    /** Diameter of progress circle */
    diameter: PropTypes.number,
    /** Percentage of 100 that is complete */
    progress: PropTypes.number.isRequired,
    /** Optional label for the percentage */
    label: PropTypes.string,
    /** Color palette to apply */
    color: PropTypes.oneOf([
        'blue',
        'teal'

    gradient: PropTypes.bool,

    glow: PropTypes.bool,
    /** Flag to determine if the progress should animate on load */
    animated: PropTypes.bool
}

static defaultProps = {
    strokeWidth: 6,
    diameter: 150,
    progress: 0,
    label: '',
    color: 'blue',
    gradient: true,
    glow: false,
    animated: false

    super(props);

    this.state = {
        mounted: false
    };
}

componentDidMount = () => {
    window.requestAnimationFrame(() => {
        this.setState({
            mounted: true
        });

    window.requestAnimationFrame(() => {
        this.setState({
            mounted: false

}

/** Circumference =  Pi times diameter.  We subtact half a stroke width on either side to see where the circle center is */

    return Math.PI * (this.props.diameter - this.props.strokeWidth);
}

    const circumference = this.getCircumference();
    const progress = value / 100;

    return circumference * (1 - progress);

    const progressClasses = (color)
        ? classNames('progress-radial', `progress-radial--${color}`, className)

    const progressContents = (!children && label) ? (

calculateProgress

这将影响内部文本和条形图。如果您只想限制条形，请在const progress = Math.min(value, 100) / 100; 中执行：

progressBarStyle
