react-input-range

InputRange 是一个 React 组件,允许用户输入特定范围内的数值。 它可以接受单个值或一系列值(最小值/最大值)。 默认情况下,应用基本样式,但可以根据您的设计要求进行覆盖。

Build Status

Demo

此处提供了 CodePen 演示。

Installation

  1. Install react-input-range using npm (or yarn). npm install react-input-range
  2. Import react-input-range to use InputRange component.
  3. Optionally, import react-input-range/lib/css/index.css if you want to apply the default styling.

Usage

接受最小/最大值:

import React from 'react';
import ReactDOM from 'react-dom';
import InputRange from 'react-input-range';

class App extends React.Component {
  constructor(props) {
    super(props);

    this.state = {
      value: { min: 2, max: 10 },
    };
  }

  render() {
    return (
      <InputRange
        maxValue={20}
        minValue={0}
        value={this.state.value}
        onChange={value => this.setState({ value })} />
    );
  }
}

ReactDOM.render(
  <App />,
  document.getElementById('app')
);

接受单个值:

class App extends React.Component {
  constructor(props) {
    super(props);

    this.state = { value: 10 };
  }

  render() {
    return (
      <InputRange
        maxValue={20}
        minValue={0}
        value={this.state.value}
        onChange={value => this.setState({ value })} />
    );
  }
}

格式化标签:

<InputRange
  formatLabel={value => `${value}cm`}
  value={this.state.value}
  onChange={value => this.setState({ value })} />

指定增量/减量

<InputRange
  step={2}
  value={this.state.value}
  onChange={value => this.setState({ value })} />

API

InputRange#props

allowSameValues: boolean

设置为 true 以允许 minValuemaxValue 是一样的。

ariaLabelledby: string

为您的组件设置 aria-labelledby 属性。

ariaControls: string

为您的组件设置 aria-controls 属性。

classNames: InputRangeClassNames

覆盖应用于您的组件及其子组件的默认 CSS 类。

disabled: boolean

如果此属性设置为 true,则您的组件将被禁用。 这意味着您将无法与之交互。

draggableTrack: boolean

如果此属性设置为 true,则可以拖动整个轨道。

formatLabel: (value: number, type: string): string

默认情况下,值标签显示为纯数字。 如果你想改变显示,你可以通过传入一个函数来实现。 该函数可以返回不同的东西,即:追加一个单位,降低数字的精度。

maxValue: number

为您的组件设置最大值。 您不能将滑块拖动到该值之外。

minValue: number

为您的组件设置一个最小值。 您不能将滑块拖动到该值以下。

name: string

为您的表单组件设置一个名称。

onChange: (value: number | Range): void

每当您的用户与您的组件交互(即:拖动滑块)时,都会调用此函数。 在函数内部,您应该将新值分配给您的组件。

onChangeStart: (value: number | Range): void

每当您的用户开始与您的组件交互时(即:onMouseDownonTouchStart),都会调用此函数。

onChangeComplete: (value: number | Range): void

每个鼠标/触摸事件都可以触发多次更新,因此导致多次触发 onChange 回调。 另一方面,onChangeComplete 回调只会在用户停止拖动时被调用。

step: number

组件的默认增量/减量为 1。您可以通过为此属性设置不同的数字来更改它。

value: number | Range

设置组件的当前值。 如果只提供一个数字,则只会呈现一个滑块。 如果提供范围对象(最小值/最大值),将呈现两个滑块

Types

InputRangeClassNames

  • activeTrack: string
  • disabledInputRange: string
  • inputRange: string
  • labelContainer: string
  • maxLabel: string
  • minLabel: string
  • slider: string
  • sliderContainer: string
  • track: string
  • valueLabel: string

Range

  • max: number
  • min: number

Development

如果你想在本地处理这个项目,你需要获取它的所有依赖项,为此 我们推荐使用 yarn。 您可以在此处找到设置 yarn 的说明。

yarn install

之后,你应该可以运行预览

yarn dev

来测试

yarn test

react-input-range

InputRange is a React component allowing users to input numeric values within a specific range. It can accept a single value, or a range of values (min/max). By default, basic styles are applied, but can be overridden depending on your design requirements.

Build Status

Demo

A CodePen demo is available here.

Installation

  1. Install react-input-range using npm (or yarn). npm install react-input-range
  2. Import react-input-range to use InputRange component.
  3. Optionally, import react-input-range/lib/css/index.css if you want to apply the default styling.

Usage

To accept min/max value:

import React from 'react';
import ReactDOM from 'react-dom';
import InputRange from 'react-input-range';

class App extends React.Component {
  constructor(props) {
    super(props);

    this.state = {
      value: { min: 2, max: 10 },
    };
  }

  render() {
    return (
      <InputRange
        maxValue={20}
        minValue={0}
        value={this.state.value}
        onChange={value => this.setState({ value })} />
    );
  }
}

ReactDOM.render(
  <App />,
  document.getElementById('app')
);

To accept a single value:

class App extends React.Component {
  constructor(props) {
    super(props);

    this.state = { value: 10 };
  }

  render() {
    return (
      <InputRange
        maxValue={20}
        minValue={0}
        value={this.state.value}
        onChange={value => this.setState({ value })} />
    );
  }
}

To format labels:

<InputRange
  formatLabel={value => `${value}cm`}
  value={this.state.value}
  onChange={value => this.setState({ value })} />

To specify the amount of increment/decrement

<InputRange
  step={2}
  value={this.state.value}
  onChange={value => this.setState({ value })} />

API

InputRange#props

allowSameValues: boolean

Set to true to allow minValue and maxValue to be the same.

ariaLabelledby: string

Set aria-labelledby attribute to your component.

ariaControls: string

Set aria-controls attribute to your component.

classNames: InputRangeClassNames

Override the default CSS classes applied to your component and its sub-components.

disabled: boolean

If this property is set to true, your component is disabled. This means you'll not able to interact with it.

draggableTrack: boolean

If this property is set to true, you can drag the entire track.

formatLabel: (value: number, type: string): string

By default, value labels are displayed as plain numbers. If you want to change the display, you can do so by passing in a function. The function can return something different, i.e.: append a unit, reduce the precision of a number.

maxValue: number

Set a maximum value for your component. You cannot drag your slider beyond this value.

minValue: number

Set a minimum value for your component. You cannot drag your slider under this value.

name: string

Set a name for your form component.

onChange: (value: number | Range): void

Whenever your user interacts with your component (i.e.: dragging a slider), this function gets called. Inside the function, you should assign the new value to your component.

onChangeStart: (value: number | Range): void

Whenever your user starts interacting with your component (i.e.: onMouseDown, or onTouchStart), this function gets called.

onChangeComplete: (value: number | Range): void

Every mouse / touch event can trigger multiple updates, therefore causing onChange callback to fire multiple times. On the other hand, onChangeComplete callback only gets called when the user stops dragging.

step: number

The default increment/decrement of your component is 1. You can change that by setting a different number to this property.

value: number | Range

Set the current value for your component. If only a single number is provided, only a single slider will get rendered. If a range object (min/max) is provided, two sliders will get rendered

Types

InputRangeClassNames

  • activeTrack: string
  • disabledInputRange: string
  • inputRange: string
  • labelContainer: string
  • maxLabel: string
  • minLabel: string
  • slider: string
  • sliderContainer: string
  • track: string
  • valueLabel: string

Range

  • max: number
  • min: number

Development

If you want to work on this project locally, you need to grab all of its dependencies, for which we recommend using yarn. You can find the instructions to setup yarn here.

yarn install

After that, you should be able run to preview

yarn dev
