Customize the ticks in EJ2 TypeScript Range slider control
15 May 202311 minutes to read
Slider view can be customized via CSS. By overriding the slider CSS classes, you can customize the ticks. The ticks in slider allows you to easily identify the current value/values of the slider. It contains smallStep and largeStep. By default, slider has class e-tick for slider ticks. You can override the class as per your requirement. Refer to the following code snippet to render ticks.
.e-scale .e-tick.e-custom::before {
content: '\e967';
position: absolute;
}Here, the color for rendered ticks has been applied through nth-child(child_number). The color is applied to the value of the child_number in the slider.
#ticks_slider .e-scale :nth-child(1)::before {
color: red;
}import { enableRipple } from '@syncfusion/ej2-base';
enableRipple(true);
import { Slider, SliderTickRenderedEventArgs, SliderTickEventArgs } from '@syncfusion/ej2-inputs';
// Initialize slider component
let ticksSlider: Slider = new Slider({
// Set slider minimum and maximum values
min: 0, max: 100,
// Set the initial value for slider
value: 30,
// Set the step value for slider
step: 5,
// Set the type to render minRange slider
type: 'MinRange',
// Initialize ticks with placement, largestep
ticks: { placement: 'Before', largeStep: 20 },
// Handler used to add custom class to all tick element
renderingTicks: (args: SliderTickEventArgs) => {
if (args.tickElement.classList.contains('e-large')) {
args.tickElement.classList.add('e-custom');
}
}
});
ticksSlider.appendTo('#ticks_slider');
// Initialize slider component
let customTicks: Slider = new Slider({
// Set slider minimum and maximum values
min: 0, max: 100,
// Set the initial value for slider
value: 30,
// Set the type to render minRange slider
type: 'MinRange',
// Initialize ticks with placement, largestep, smallstep
ticks: { placement: 'Both', largeStep: 20, smallStep: 5 },
// Handler used to customize tick element
renderedTicks: (args: SliderTickRenderedEventArgs) => {
let li: any = args.ticksWrapper.getElementsByClassName('e-large');
let remarks: any = ['Very Poor', 'Poor', 'Average', 'Good', 'Very Good', 'Excellent'];
for (let i: number = 0; i < li.length; ++i) {
(li[i].querySelectorAll('.e-tick-both')[1] as HTMLElement).innerText = remarks[i];
}
}
});
customTicks.appendTo('#slider');<!DOCTYPE html>
