zent/src/datetimepicker/time/SecondPanel.js

一套前端设计语言和基于React的实现

import React, { Component, PureComponent } from 'react';
import classNames from 'classnames';
import PanelHeader from '../common/PanelHeader';
import TimeCell from './TimeCell';
import { CURRENT, padLeft } from '../utils';

const ROW = 9;
const COL = 7;

export default class SecondPanel extends (PureComponent || Component) {
  isSelected(val) {
    const { selected } = this.props;
    return selected.getSeconds() === val;
  }

  isCurrent(val) {
    return CURRENT.getSeconds() === val;
  }

  getSeconds() {
    const cells = [];
    let i = 0;
    for (let j = 0; j < ROW; j++) {
      cells[j] = [];
      for (let k = 0; k < COL && i < 60; k++) {
        const isDisabled = this.props.isDisabled && this.props.isDisabled(i);
        const isSelected = this.isSelected(i);
        const isCurrent = this.isCurrent(i);
        let className = classNames({
          'panel__cell time-panel__cell': true,
          'panel__cell--disabled': isDisabled,
          'panel__cell--selected': isSelected,
          'panel__cell--current': isCurrent
        });
        cells[j][k] = {
          text: padLeft(i),
          value: i,
          isDisabled,
          className
        };
        i++;
      }
    }

    return cells;
  }

  render() {
    const { hidePanel, onSelect } = this.props;
    const seconds = this.getSeconds();
    const title = '选择秒';

    return (
      <div className="second-panel">
        <PanelHeader title={title} showNext={false} prev={hidePanel} />
        <div className="second-table panel-table">
          <TimeCell cells={seconds} onSelect={onSelect} />
        </div>
      </div>
    );
  }
}
