Achieve date format

The date formatting can be achieved in ticks and tooltip using renderingTicks and tooltipChange events, respectively. The process of formatting is explained in the following sample.

import { Slider, SliderTickEventArgs, SliderTooltipEventArgs } from '@syncfusion/ej2-inputs';

// Initialize slider control
 let dateObj: Slider = new Slider({

    /**
     * Initialize the min and max values of the slider using JavaScript date functions
     * new Date (Year, Month, day, hours, minutes, seconds, milliseconds)
     */

    min: new Date("2013-06-13").getTime(),
    value: new Date("2013-06-15").getTime(),
    max: new Date("2013-06-21").getTime(),
    // 86400000 milliseconds for a day
    step: 86400000,
    tooltipChange: function (args: SliderTooltipEventArgs) {
        let totalMiliSeconds = Number(args.text);
        // Convert the current milliseconds to the respective date in desired format
        let custom = { year: "numeric", month: "short", day: "numeric" };
        args.text = new Date(totalMiliSeconds).toLocaleDateString("en-us", custom);
    },
    tooltip: {
        placement: 'Before',
        isVisible: true
    },
    renderingTicks: function (args: SliderTickEventArgs) {
        let totalMiliSeconds = Number(args.value);
        // Convert the current milliseconds to the respective date in desired format
        let custom = { year: "numeric", month: "short", day: "numeric" };
        args.text = new Date(totalMiliSeconds).toLocaleDateString("en-us", custom);
    },
    ticks: {
        placement: 'After',
        // 2 * 86400000 milliseconds for two days
        largeStep: 2 * 86400000
    },
    showButtons: true
});
// Render initialized Slider
dateObj.appendTo('#slider');

Achieve time format

The time formatting can be achieved in the same manner as date formatting using renderingTicks and change events. The process of time formatting is explained in the following sample.

    step: 3600000,
    tooltipChange: function (args: SliderTooltipEventArgs) {

    tooltip: {
        placement: 'Before',

    },
    renderingTicks: function (args: SliderTickEventArgs) {
        let totalMiliSeconds = Number(args.value);
        let custom = { hour: '2-digit', minute: '2-digit' };
        args.text = new Date(totalMiliSeconds).toLocaleTimeString("en-us", custom);
    },
    ticks: {
        placement: 'After',
        // 2 * 3600000 milliseconds = 2 Hour
        largeStep: 2 * 3600000
    },
    showButtons: true
});
// Render initialized slider
timeObj.appendTo('#slider');

Customize numeric Value

The numeric values can be formatted into different decimal digits or fixed number of whole numbers or to represent units. The numeric processing is demonstrated as follows.
