Show slider from hidden state in EJ2 JavaScript Range slider control

15 May 20236 minutes to read

This section demonstrates how-to render the Slider component in hidden state and make it visible in button click. We can initialize Slider in hidden state by setting the display as none.

In the sample, by clicking on the button, we can make the Slider visible from hidden state, and we must also call the refresh method of the Slider to render it properly based on its original dimensions.

// Initialize button component
var button = new ej.buttons.Button({ content: 'Button' });
button.appendTo('#element');
// Initialize Slider component
var defaultObj = new ej.inputs.Slider({
	// Set slider minimum and maximum values
	// new Date(Year, Month, day, hours, minutes, seconds, millseconds)
	min: new Date(2013, 6, 13, 11).getTime(), max: new Date(2013, 6, 13, 17).getTime(),
	// 3600000 milliseconds = 1 Hour
	step: 3600000,
	//Set buttons for slider 
    showButtons: true,
	// Set the initial range values for slider
	value: new Date(2013, 6, 13, 13).getTime(),
	// Bind Tooltip change event for custom formatting
	tooltipChange: tooltipChangeHandler,
	// Initialize tooltip with placement
	tooltip: {
		placement: 'Before', isVisible: true, cssClass: 'e-tooltip-cutomization'
	},
	// Bind ticks event for custom formatting
	renderingTicks: renderingTicksHandler,
	// Initialize ticks with placement, largestep, smallstep
	ticks: {
		placement: 'After',
		// 2 * 3600000 milliseconds = 2 Hour
		largeStep: 2 * 3600000,
		smallStep: 3600000, showSmallTicks: true
	},
	// Set the type to render range slider
	type: 'MinRange'
});
defaultObj.appendTo('#slider');

function tooltipChangeHandler(args) {
	/**
	  * toLocaleTimeString is predefined javascript date function, which is used to
	  * customize the date in different format
	  */
	var custom = { hour: '2-digit', minute: '2-digit' };
	// Splitting the range values from the tooltip using space into an array.
	if (args.text.indexOf('-') !== -1) {
		var totalMilliSeconds = args.text.split(' ');
		// First part is the first handle value
		var firstPart = totalMilliSeconds[0];
		// Second part is the second handle value
		var secondPart = totalMilliSeconds[2];

		firstPart = new Date(Number(firstPart)).toLocaleTimeString('en-us', custom);
		secondPart = new Date(Number(secondPart)).toLocaleTimeString('en-us', custom);
	} else {
		args.text =  new Date(Number(args.text)).toLocaleTimeString('en-us', custom);
	}
}

function renderingTicksHandler(args) {
	var totalMilliSeconds = args.value;
	/**
	 * toLocaleTimeString is predefined javascript date function, which is used to
	 * customize the date in different format
	 */
	var custom = { hour: '2-digit', minute: '2-digit' };
	// Assigning our custom text to the tick value.
	args.text = new Date(totalMilliSeconds).toLocaleTimeString('en-us', custom);
}

//Visible slider by clicking the button
document.getElementById('element').onclick = function () {
	slider = document.getElementById("case");
	ticks = document.getElementById("slider");
	slider.style.display = "block";
	ticks.ej2_instances[0].refresh();
};
