API

createSliderWithTooltip(Slider | Range) => React.Component

An extension to make Slider or Range support Tooltip on handle.

const Slider = require('@gem-mine/rc-slider');
const createSliderWithTooltip = Slider.createSliderWithTooltip;
const Range = createSliderWithTooltip(Slider.Range);

Online demo

After Range or Slider was wrapped by createSliderWithTooltip, it will have the following props:

| Name | Type | Default | Description | | ------------ | ------- | ------- | ----------- | | tipFormatter | (value: number): React.ReactNode | value => value | A function to format tooltip's overlay | | tipProps | Object | { placement: 'top', prefixCls: 'rc-slider-tooltip', overlay: tipFormatter(value) } | A function to format tooltip's overlay |

Common API

The following APIs are shared by Slider and Range.

| Name | Type | Default | Description | | ------------ | ------- | ------- | ----------- | | className | string | '' | Additional CSS class for the root DOM node | | min | number | 0 | The minimum value of the slider | | max | number | 100 | The maximum value of the slider | | marks | {number: string} or{number: { style, label }} | {} | Marks on the slider. The key determines the position, and the value determines what will show. If you want to set the style of a specific mark point, the value should be an object which contains style and label properties. | | step | number or null | 1 | Value to be added or subtracted on each step the slider makes. Must be greater than zero, and max - min should be evenly divisible by the step value. When marks is not an empty object, step can be set to null, to make marks as steps. | | vertical | boolean | false | If vertical is true, the slider will be vertical. | | handle | (props) => React.ReactNode | | A handle generator which could be used to customized handle. | | included | boolean | true | If the value is true, it means a continuous value interval, otherwise, it is a independent value. | | disabled | boolean | false | If true, handles can't be moved. | | dots | boolean | false | When the step value is greater than 1, you can set the dots to true if you want to render the slider with dots. | | onBeforeChange | Function | NOOP | onBeforeChange will be triggered when ontouchstart or onmousedown is triggered. | | onChange | Function | NOOP | onChange will be triggered while the value of Slider changing. | | onAfterChange | Function | NOOP | onAfterChange will be triggered when ontouchend or onmouseup is triggered. | | minimumTrackStyle | Object | | please use trackStyle instead. (only used for slider, just for compatibility , will be deprecate at [email protected] ) | | maximumTrackStyle | Object | | please use railStyle instead (only used for slider, just for compatibility , will be deprecate at [email protected]) | | handleStyle | Array[Object] | Object | [{}] | The style used for handle.
