Format in React Range Slider component

28 Feb 202518 minutes to read

The format feature is used to customize the units of Slider values to desired format. The formatted values will also be applied to the ARIA attributes of the slider. There are two ways to achieve formatting in the slider.

Use the format API of the Slider which utilizes our Internationalization to format values.
Customize using events namely renderingTicks and tooltipChange.

index.jsx
index.tsx
index.css
index.html
import * as React from 'react';
import * as ReactDOM from "react-dom";
import { SliderComponent } from '@syncfusion/ej2-react-inputs';
function App() {
  let tooltip = { isVisible: true, format: "C2" };
  let value = 30;
  // Slider ticks customization
  let ticks = {
    placement: "After",
    format: "C2",
    largeStep: 20,
    smallStep: 10,
    showSmallTicks: true
  };
  return (<div id="container">
    <div className="wrap">
      <SliderComponent id="slider" min={0} max={100} value={value} tooltip={tooltip} ticks={ticks} />
    </div>
  </div>);
}
export default App;
ReactDOM.render(<App />, document.getElementById('element'));
import * as React from 'react';
import * as ReactDOM from "react-dom";
import { SliderComponent } from '@syncfusion/ej2-react-inputs';

function App() {
  let tooltip = { isVisible: true, format: "C2" };
  let value = 30;
  // Slider ticks customization
  let ticks: TicksDataModel = {
    placement: "After",
    format: "C2",
    largeStep: 20,
    smallStep: 10,
    showSmallTicks: true
  };

  return (
    <div id="container">
      <div className="wrap">
        <SliderComponent
          id="slider"
          min={0}
          max={100}
          value={value}
          tooltip={tooltip}
          ticks={ticks}
        />
      </div>
    </div>
  );
}
export default App;
ReactDOM.render(<App />, document.getElementById('element'));

Using format API

In this method, we have different predefined formatting styles like Numeric (N), Percentage (P), Currency (C) and # specifiers. In the example below, we have formatted the ticks and tooltip values into percentage.

index.jsx
index.tsx
index.css
index.html
import * as React from 'react';
import * as ReactDOM from "react-dom";
import { SliderComponent } from '@syncfusion/ej2-react-inputs';
function App() {
  let tooltip = {
    placement: "Before",
    isVisible: true,
    showOn: "Always",
    format: "P0"
  };
  let value = 0.3;
  // Slider ticks customization
  let ticks = {
    placement: "After",
    largeStep: 0.2,
    smallStep: 0.1,
    showSmallTicks: true,
    format: "P0"
  };
  return (<div id="container">
    <div className="wrap">
      <SliderComponent id="slider" min={0} max={1} step={0.01} value={value} tooltip={tooltip} ticks={ticks} />
    </div>
  </div>);
}
export default App;
ReactDOM.render(<App />, document.getElementById('element'));
import * as React from 'react';
import * as ReactDOM from "react-dom";
import { SliderComponent } from '@syncfusion/ej2-react-inputs';

function App() {
  let tooltip: TooltipDataModel = {
    placement: "Before",
    isVisible: true,
    showOn: "Always",
    format: "P0"
  };
  let value = 0.3;
  // Slider ticks customization
  let ticks: TicksDataModel = {
    placement: "After",
    largeStep: 0.2,
    smallStep: 0.1,
    showSmallTicks: true,
    format: "P0"
  };

  return (
    <div id="container">
      <div className="wrap">
        <SliderComponent
          id="slider"
          min={0}
          max={1}
          step={0.01}
          value={value}
          tooltip={tooltip}
          ticks={ticks}
        />
      </div>
    </div>
  );
}
export default App;
ReactDOM.render(<App />, document.getElementById('element'));
.sliderwrap {
  margin-top: 20px;
}

.sliderwrap label {
  font-size: 13px;
  font-weight: 100;
  margin-top: 15px;
  padding-bottom: 15px;
}

.wrap {
  box-sizing: border-box;
  height: 100px;
  margin: 0 auto;
  padding: 30px 10px;
  width: 460px;
}

.wrap .label {
  text-align: center;
}

.labeltext {
  text-align: center;
}

Using Events

In this method, we retrieve the values from the Slider events then process them to the desired formatted values.
In this sample, we have customized the ticks values into weekdays as one formatting and tooltip values into day of the week as another formatting.

index.jsx
index.tsx
index.css
index.html
import * as React from 'react';
import * as ReactDOM from "react-dom";
import { SliderComponent } from '@syncfusion/ej2-react-inputs';
function App() {
  let tooltip = { placement: "Before", isVisible: true };
  let value = 2;
  // Slider ticks customization
  let ticks = { placement: "After", largeStep: 1 };
  function renderingTicksHandler(args) {
    // Weekdays Array
    let daysArr = [
      "Sunday",
      "Monday",
      "Tuesday",
      "Wednesday",
      "Thrusday",
      "Friday",
      "Saturday"
    ];
    // Customizing each ticks text into weeksdays
    args.text = daysArr[parseFloat(args.value.toString())];
  }
  function tooltipChangeHandler(args) {
    // Customizing tooltip to display the Day (in numeric) of the week
    args.text = "Day " + (Number(args.value) + 1).toString();
  }
  return (<div id="container">
    <div className="wrap">
      <SliderComponent id="slider" min={0} max={6} step={1} value={value} tooltip={tooltip} ticks={ticks} tooltipChange={tooltipChangeHandler.bind(this)} renderingTicks={renderingTicksHandler.bind(this)} />
    </div>
  </div>);
}
export default App;
ReactDOM.render(<App />, document.getElementById('element'));
import * as React from 'react';
import * as ReactDOM from "react-dom";
import { SliderComponent } from '@syncfusion/ej2-react-inputs';

function App() {
  let tooltip: TooltipDataModel = { placement: "Before", isVisible: true };
  let value = 2;
  // Slider ticks customization
  let ticks: TicksDataModel = { placement: "After", largeStep: 1 };

  function renderingTicksHandler(args: SliderTickEventArgs) {
    // Weekdays Array
    let daysArr: string[] = [
      "Sunday",
      "Monday",
      "Tuesday",
      "Wednesday",
      "Thrusday",
      "Friday",
      "Saturday"
    ];
    // Customizing each ticks text into weeksdays
    args.text = daysArr[parseFloat(args.value.toString())];
  }

  function tooltipChangeHandler(args: SliderTooltipEventArgs) {
    // Customizing tooltip to display the Day (in numeric) of the week
    args.text = "Day " + (Number(args.value) + 1).toString();
  }

  return (
    <div id="container">
      <div className="wrap">
        <SliderComponent
          id="slider"
          min={0}
          max={6}
          step={1}
          value={value}
          tooltip={tooltip}
          ticks={ticks}
          tooltipChange={tooltipChangeHandler.bind(this) as any}
          renderingTicks={renderingTicksHandler.bind(this) as any}
        />
      </div>
    </div>
  );
}
export default App;
ReactDOM.render(<App />, document.getElementById('element'));
.sliderwrap {
  margin-top: 20px;
}

.sliderwrap label {
  font-size: 13px;
  font-weight: 100;
  margin-top: 15px;
  padding-bottom: 15px;
}

.wrap {
  box-sizing: border-box;
  height: 100px;
  margin: 0 auto;
  padding: 30px 10px;
  width: 460px;
}

.wrap .label {
  text-align: center;
}

.labeltext {
