css - 使用 CSS-in-JS 设计 ReactSelect
问题描述
这是我最初回答的另一个好 stackoverflow 帖子的链接。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,但是选择框的高度(总共 29 像素)比默认的 ReactSelect 小得多,这是我的第一个造型目标(降低高度)。这是我现在试图降低高度的代码,主要来自我链接到的stackoverflow帖子:
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,当我使用customStyles
而不是customControlStyles
在上面的示例中时,样式不再起作用,并且我不确定我在创建customStyles
时做错了什么导致它不起作用。我想我需要做一些类似的事情customStyles
,因为看起来我需要的不仅仅是control
ReactSelect 的一部分。
第二,我想删除 ReactSelect 中的竖线和向下插入符号,类似于初始屏幕截图。
任何有关此样式的帮助将不胜感激!我已经为此工作了很长一段时间,但还没有成功。谢谢!
解决方案
选项1
确保您使用的是最新版本的 react-select (v2.3.0)。通过使用react-select 提供的CSS
一些功能,我能够完成您想要的。style keys
工作示例:https ://codesandbox.io/s/7y6901y950
容器/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

label="FG:"
placeholder="Field Goals"
handleChange={this.handleChange}
selectOptions={fgOptions}

ratio 会有所不同)
export const selectStyles = {

选项 2
或者,您可以在不使用 的情况下完成所有操作react-select
,我强烈建议您这样做,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)。
