Format in EJ2 TypeScript Range slider control
29 Aug 202312 minutes to read
The format
feature 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 of achieving formatting in slider.
-
Use the format API of slider which utilizes our Internationalization to format values.
-
Customize using the events namely
renderingTicks
andtooltipChange
.
import { Slider } from '@syncfusion/ej2-inputs';
// Initialize Slider control
let sliderObj: Slider = new Slider({
min: 0, max: 100, step: 1, value: 30,
// Applying currency formatting for tooltip with two decimal specifiers
tooltip: { isVisible: true, format: 'C2' },
// Applying currency formatting for ticks with two decimal specifiers
ticks: { placement: 'After', format: 'C2', largeStep: 20, smallStep: 10, showSmallTicks: true }
});
// Render initialized Slider
sliderObj.appendTo('#slider');

Using format API
In this method, we have different predefined formatting styles like Numeric (N), Percentage (P), Currency (C) and #
specifiers. In this below example we have formatted the ticks
and tooltip
values into percentage.
import { Slider } from '@syncfusion/ej2-inputs';
// Initialize Slider control
let percentObj: Slider = new Slider({
min: 0, max: 1, value: .3, step: .01,
// Assigning ticks values to percentage formatting
ticks: { placement: 'After', largeStep: .2, smallStep: .1, showSmallTicks: true, format: 'P0' },
// Assigning tooltip values to percentage formatting
tooltip: { placement: 'Before', isVisible: true, showOn: 'Always', format: 'P0' },
});
// Render initialized Slider
percentObj.appendTo('#slider');

Using Events
In this method, we will be retrieving the values from the slider events then process them to desired formatted the 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.
import { Slider, SliderTickEventArgs, SliderTooltipEventArgs } from '@syncfusion/ej2-inputs';
// Initialize Slider control
let eventObj: Slider = new Slider({
// Minimum value
min: 0,
// Maximum value
max: 6,
// Slider current value
value: 2,
// Assigning ticks data
ticks: {
placement: 'After',
largeStep: 1
},
renderingTicks: function (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 as any)];
},
tooltipChange: function (args: SliderTooltipEventArgs) {
// Customizing tooltip to display the Day (in numeric) of the week
args.text = 'Day ' + (Number(args.value) + 1).toString();
},
// Assigning tooltip data
tooltip: {
placement: 'Before',
isVisible: true
}
});
// Render initialized Slider
eventObj.appendTo('#slider');
