React设计权限控制时通过cloneElement修改元素的props属性

interface Iprops {
    roles: string;
}

export class Authorize extends React.Component<Iprops, any>{
    renderDom() {
        const { roles, children } = this.props;
        if (authorize(roles) === true) {
            return this.props.children;
        } else if (authorize(roles) === ‘disable‘) {
            return Children.map(children, (child: any) => cloneElement(child, { disabled: true }));
        } else {
            return null;
        }
    }

    render(): any {
        return this.renderDom();
    }
}
