NumberBox creates a box (or button) based numeric UI component. It is used for filtering results based on a numeric query.

Example uses:

filtering hotel listings based on the number of guests,
filtering movies or products by ratings.

Usage

Basic Usage

Copy

<NumberBox
	componentId="NumberBoxSensor"
	dataField="guests"
	data={{ label: 'Guests', start: 0, end: 5 }}
	title="NumberBox component"
/>

Usage With All Props

Copy

<NumberBox
	componentId="NumberBoxSensor"
	dataField="guests"
	data={{ label: 'Guests', start: 0, end: 5 }}
	title="NumberBox component"
	defaultValue={0}
	labelPosition="left"
	queryFormat="gte"
	URLParams={false}
/>

Props

componentId String unique identifier of the component, can be referenced in other components' react prop.
dataField String DB data field to be mapped with the component's UI view. The selected box value creates a database query on this field.
data Object an object with start and end values and optionally an associated label to be displayed in the UI.
nestedField String [optional] use to set the nested mapping field that allows arrays of objects to be indexed in a way that they can be queried independently of each other. Applicable only when dataField is a part of nested type.
title String or JSX [optional] title of the component to be shown in the UI.
defaultValue Number [optional] sets a initial valid value within the [start, end] range on mount.
value Number [optional] controls the current value of the component (on mount and on update).Use this prop in conjunction with onChange function.
onChange function [optional] is a callback function which accepts component's current value as a parameter. It is called when you are using the value prop and the component's value changes. This prop is used to implement the controlled component behavior.
labelPosition String [optional] position where label is shown, one of "left", "top", "right", "bottom". Defaults to left.
queryFormat String [optional] type of query to perform, one of exact, gte and lte:
- exact implies a query match with the exact value as the one selected in the UI view,
- gte implies a query match that satisfies all values that are greater than or equal to the one selected in the UI view.
- lte implies a query match that satisfies all values that are less than or equal to the one selected in the UI view.
Defaults to gte.
URLParams Boolean [optional] enable creating a URL query string parameter based on the selected value of the number. This is useful for sharing URLs with the component state. Defaults to false.

Demo

Styles

NumberBox component supports innerClass prop with the following keys:

title
label
button

Extending

NumberBox component can be extended to

customize the look and feel with className, style,
update the underlying DB query with customQuery,
connect with external interfaces using beforeValueChange, onValueChange and onQueryChange.

Copy

<NumberBox
  ...
  className="custom-class"
  style={{"paddingBottom": "10px"}}
  customQuery={
    function(value, props) {
      return {
        query: {
            match: {
                data_field: "this is a test"
            }
        }
      }
    }
  }
  beforeValueChange={
    function(value) {
      // called before the value is set
      // returns a promise
      return new Promise((resolve, reject) => {
        // update state or component props
        resolve()
        // or reject()
      })
    }
  }
  onValueChange={
    function(value) {
      console.log("current value: ", value)
      // set the state
      // use the value with other js code
    }
  }
  onQueryChange={
    function(prevQuery, nextQuery) {
      // use the query with other js code
      console.log('prevQuery', prevQuery);
      console.log('nextQuery', nextQuery);
    }
  }
/>

className String CSS class to be injected on the component container.
style Object CSS styles to be applied to the NumberBox component.
customQuery Function takes value and props as parameters and returns the data query to be applied to the component, as defined in Elasticsearch Query DSL. Note: customQuery is called on value changes in the NumberBox component as long as the component is a part of react dependency of at least one other component.
beforeValueChange Function is a callback function which accepts component's future value as a parameter and returns a promise. It is called everytime before a component's value changes. The promise, if and when resolved, triggers the execution of the component's query and if rejected, kills the query execution. This method can act as a gatekeeper for query execution, since it only executes the query after the provided promise has been resolved.

Note:

If you're using Reactivesearch version >= 3.3.7, beforeValueChange can also be defined as a synchronous function. value is updated by default, unless you throw an Error to reject the update. For example:

Copy
```
beforeValueChange = value => {
    // The update is accepted by default
	if (value > 10) {
		// To reject the update, throw an error
		throw Error('No of persons must be less than or equal to 10.');
	}
};
```
onValueChange Function is a callback function which accepts component's current value as a parameter. It is called everytime the component's value changes. This prop is handy in cases where you want to generate a side-effect on value selection. For example: You want to show a pop-up modal with the valid discount coupon code when a number is selected in a NumberBox.
onQueryChange Function is a callback function which accepts component's prevQuery and nextQuery as parameters. It is called everytime the component's query changes. This prop is handy in cases where you want to generate a side-effect whenever the component's query would change.
index String [optional] The index prop can be used to explicitly specify an index to query against for this component. It is suitable for use-cases where you want to fetch results from more than one index in a single ReactiveSearch API request. The default value for the index is set to the app prop defined in the ReactiveBase component.

Note: This only works when enableAppbase prop is set to true in ReactiveBase.
