使用 CSS-in-JS 对 ReactSelect 进行样式化

Question

是 link 另一个很好的 Whosebug post 的基础，我的初始答案基于此。我正在尝试设置我的 ReactSelect 组件的样式，使其看起来像这样：

从上面的屏幕截图中看不出来，但是 select 框的高度（总共 29 像素）比默认的 ReactSelect 小得多，这是我的第一个 objective 样式（减少高度）。这是我现在试图降低高度的代码，主要来自 Whosebug post 我已经 linked 到：

const customStyles = {
    control: base => ({
        ...base,
        height: 22,
        minHeight: 22
    })
};

const customControlStyles = base => ({
    ...base,
    height: 22,
    minHeight: 22
});

const selectOptions = [
    { value: 'pct', label: 'FG Percentage' },
    { value: 'attFreq', label: 'FG Frequency' },
    { value: 'made', label: 'Total Makes' },
    { value: 'att', label: 'Total Attempts' }];

const shotdistSelect =
    (<Select
        // arrowRenderer={null}
        maxMenuHeight={30}
        placeholder={'Knickerbockers'}
        isClearable={false}
        isDisabled={this.props.loading}
        backspaceRemovesValue={false}
        isSearchable={true}
        value={this.state.shotdistType}
        onChange={this.handleShotdistChange}
        options={selectOptions}
        styles={{ control: customControlStyles }}
        // styles={{ customStyles }}
    />);

这是上面示例的结果：

...不完全是我想要的。此外，当我在上面的示例中使用 customStyles 而不是 customControlStyles 时，样式不再有效，而且我不确定在创建导致它的 customStyles 时我做错了什么不工作。我想我需要做一些类似于 customStyles 的事情，因为看起来我需要的样式不仅仅是 ReactSelect 的 control 部分。

和 2nd，我想删除 ReactSelect 中的垂直条和向下插入符，类似于初始屏幕截图。

如果您对此样式有任何帮助，我们将不胜感激！！我已经为此工作了很长一段时间，但还没有成功。谢谢！

确保您使用的是最新版本的 react-select (v2.3.0)。我能够通过使用一些 CSS 和 react-select.

提供的 style keys 来完成你想要的

工作示例：https://codesandbox.io/s/7y6901y950

containers/Form/Form.js

import React, { Component } from "react";
import CustomSelect from "../../components/CustomSelect/CustomSelect";

const fgOptions = [
  { value: "pct", label: "FG Percentage" },
  { value: "attFreq", label: "FG Frequency" },
  { value: "made", label: "Total Makes" },
  { value: "att", label: "Total Attempts" }
];

const saveOptions = [
  { value: "pct", label: "Save Percentage" },
  { value: "sFreq", label: "Save Frequency" },
  { value: "tSaves", label: "Total Saves" }
];

const assistOptions = [
  { value: "pct", label: "Assist Percentage" },
  { value: "aFreq", label: "Assist Frequency" },
  { value: "tAssist", label: "Total Assists" }
];

export default class Form extends Component {
  handleChange = (name, value) => {
    this.setState({ [name]: value });
  };

  handleSubmit = e => {
    e.preventDefault();
    alert(JSON.stringify(this.state, null, 4));
  };

  render = () => (
    <form onSubmit={this.handleSubmit} className="app-container">
      <h1>React Select Styling</h1>
      <CustomSelect
        name="fg"
        label="FG:"
        placeholder="Field Goals"
        handleChange={this.handleChange}
        selectOptions={fgOptions}
      />
      <CustomSelect
        name="assists"
        label="AS:"
        placeholder="Assists"
        handleChange={this.handleChange}
        selectOptions={assistOptions}
      />
      <CustomSelect
        name="saves"
        label="SV:"
        placeholder="Saves"
        handleChange={this.handleChange}
        selectOptions={saveOptions}
      />
      <button type="submit" className="submit">
        Submit
      </button>
    </form>
  );
}

components/CustomSelect/CustomSelect.js

import React from "react";
import PropTypes from "prop-types";
import Select from "react-select";
import { labelStyles, selectStyles } from "./styles/styles";

const CustomSelect = ({
  handleChange,
  label,
  name,
  placeholder,
  selectOptions,
  value
}) => (
  <div className="select-container">
    <label htmlFor={name} style={labelStyles}>
      {label}
    </label>
    <Select
      name={name}
      placeholder={placeholder}
      isClearable={false}
      backspaceRemovesValue={false}
      isSearchable={true}
      value={value}
      onChange={value => handleChange(name, value)}
      options={selectOptions}
      styles={selectStyles}
    />
  </div>
);

CustomSelect.propTypes = {
  handleChange: PropTypes.func.isRequired,
  label: PropTypes.string.isRequired,
  name: PropTypes.string.isRequired,
  placeholder: PropTypes.string.isRequired,
  selectOptions: PropTypes.arrayOf(
    PropTypes.shape({
      label: PropTypes.string.isRequired,
      value: PropTypes.string.isRequired
    })
  ),
  value: PropTypes.objectOf({
    value: PropTypes.string,
    label: PropTypes.string
  })
};

export default CustomSelect;

components/CustomSelect/styles/styles.js（请参阅 style keys 的文档——如果添加更长的标签，则必须调整 labelStyles width 属性；否则，label 与 select 的比率会有所不同）

export const selectStyles = {
  option: (provided, state) => ({
    ...provided,
    borderBottom: "1px dotted pink",
    color: state.isSelected ? "blue" : "",
    fontSize: 16,
    backgroundColor: state.isSelected ? "#eee" : "",
    textAlign: "left",
    cursor: "pointer"
  }),
  container: base => ({
    ...base,
    width: "100%"

  control: base => ({
    ...base,
    height: 32,
    minHeight: 32,
    fontSize: 16,
    borderRadius: 0,
    width: "100%",
    textAlign: "left",

export const labelStyles = {
  fontSize: 16,
  paddingTop: 8,
  marginRight: 5,
  width: 50,
  textAlign: "right"
};

或者，您可以在不使用 react-select 的情况下完成所有操作，我强烈推荐这样做，因为它排除了另一个依赖项！因此，您可以选择根据需要设置样式（完全通过 css、完全通过 css-in-js 或组合）。
