customize the style of rc-time-picker

问题:

I am using rc-time-picker package for my project, but I have problem with customizing the style of pop-up of my time picker component. Here is the screenshot of my component:

Firstly, I need to change the background-color of time item in the time li from light grey (in the screenshot) to #edeffe when time is hovered and selected . The following is my code:

import React from "react";
import TimePicker from "rc-time-picker";
import "rc-time-picker/assets/index.css";
import styled from 'styled-components';

const StyledTimePicker = styled(TimePicker)`
 &.rc-time-picker-panel-select-option-selected{
    background-color: #edeffe !important;
  }
`;

const DeliTimePicker = ({ value, onChange, ...others }) => {
  return (
    <StyledTimePicker
      showSecond={false}
      onChange={onChange}
      hideDisabledOptions
      minuteStep={5}
      {...others}
      value={value}
      use12Hours
    />
  );
};

export default DeliTimePicker;

From the inspection in the browser, I find the className of each item when selected is rc-time-picker-panel-select-option-selected. I also have to use styled component package for styling in my project. I can't figure out why it doesn't work via this method. The final component should look like this:

Any answer would be greatly appreciated!

You need to rearrange the order in which you're stylizing your TimePicker component. The styled-components package generates a className that needs to be applied to the TimePicker. In this case, it'll be applied to both its className and its popupClassName

Working example:

components/TimePicker/index.js

import styled from "styled-components";
import TimePicker from "./TimePicker";

const StyledTimePicker = styled(TimePicker)`
  & .rc-time-picker-panel-select-option-selected {
    background-color: #edeffe;
    font-weight: normal;
  }

  & .rc-time-picker-clear,
  & .rc-time-picker-clear-icon:after {
    font-size: 15px;
  }

  & .rc-time-picker-panel-select,
  & .rc-time-picker-input,
  & .rc-time-picker-panel-input {
    font-family: "Consolas", sans-serif;
    font-size: 16px;

    ::-webkit-scrollbar {
      width: 0;
      height: 0;
    }
  }
`;

export default StyledTimePicker;

components/TimePicker/TimePicker.js

import React from "react";
import PropTypes from "prop-types";
import moment from "moment";
import TimePicker from "rc-time-picker";
import "rc-time-picker/assets/index.css";

const DeliTimePicker = ({ className, onChange, value, ...rest }) => (
  <TimePicker
    {...rest}
    className={className}
    popupClassName={className}
    showSecond={false}
    onChange={onChange}
    hideDisabledOptions
    minuteStep={5}
    value={value}
    use12Hours
  />
);

DeliTimePicker.propTypes = {
  className: PropTypes.string.isRequired,
  onChange: PropTypes.func.isRequired,
  value: PropTypes.instanceOf(moment)
};

export default DeliTimePicker;

components/TimeSelectForm/index.js

import React, { Component } from "react";
import moment from "moment";
import TimePicker from "../TimePicker";

class TimeSelectForm extends Component {
  state = {
    value: moment()
  };

  handleChange = value => this.setState({ value });

  handleSubmit = e => {
    e.preventDefault();
    alert(moment(this.state.value).format("hh:mm a"));
  };

  render = () => (
    <form onSubmit={this.handleSubmit}>
      <TimePicker value={this.state.value} onChange={this.handleChange} />
      <br />
      <button type="submit">Submit</button>
    </form>
  );
}

export default TimeSelectForm;
