Class: @arcgis/core/widgets/Slider
Since: ArcGIS Maps SDK for JavaScript 4.12
A slider widget that can be used for filtering data, or gathering numeric input from a user. The slider can have multiple thumbs, and provides you with the ability to format labels and control user input.
See the image below for a summary of the configurable options available on this slider.
At a minimum, the slider's container or parent container must have a width set in CSS for it to render.
Example
const slider = new Slider({
container: "sliderDiv",
min: 0,
max: 100,
values: [ 50 ],
snapOnClickEnabled: false,
visibleElements: {
labels: true,
rangeLabels: true
}
}); new Slider(properties)
Parameter
optionalSee the properties for a list of all the properties that may be passed into the constructor.
Example
// Typical usage
const slider = new Slider({
container: "sliderDiv",
min: 0,
max: 100,
values: [ 50 ]

Property DetailsThe ID or node representing the DOM element containing the widget. This property can only be set once. The following examples are all valid use case when working with widgets.
Examples
// Create the HTML div element programmatically at runtime and set to the widget's container
const basemapGallery = new BasemapGallery({
view: view,
container: document.createElement("div")
});
// Add the widget to the top-right corner of the view
view.ui.add(basemapGallery, {
position: "top-right"
});// Specify an already-defined HTML div element in the widget's container
const basemapGallery = new BasemapGallery({
view: view,
container: basemapGalleryDiv
});
// Add the widget to the top-right corner of the view
view.ui.add(basemapGallery, {
position: "top-right"
});
// HTML markup
<body>
<div id="viewDiv"></div>
<div id="basemapGalleryDiv"></div>
</body>// Specify the widget while adding to the view's UI
const basemapGallery = new BasemapGallery({
view: view
});
// Add the widget to the top-right corner of the view
view.ui.add(basemapGallery, {
position: "top-right"
});Inherited
Property declaredClass Stringreadonly
The name of the class. The declared class name is formatted as esri.folder.className.
When true, sets the slider to a disabled state so the user cannot interact with it.
draggableSegmentsEnabled Boolean
Indicates if the user can drag the segment between thumbs to update thumb positions.
Example
// disables draggable segments
slider.draggableSegmentsEnabled = false;Since: ArcGIS Maps SDK for JavaScript 4.23 Slider since 4.12, effectiveMax added at 4.23.
When set, the user is restricted from moving slider thumbs to positions higher than this value. This value should be less than the slider max. The effectiveMax and effectiveMin allow you to represent ranges of values in a dataset that cannot be filtered or selected with the slider. This can be useful when using the slider to represent datasets with outliers, or scale ranges not suitable for a layer.
Example
// slider.max = 100
slider.effectiveMax = 60;
// now the user cannot slide thumbs above
// 60 even though the slider track displays
// values up to 100.Since: ArcGIS Maps SDK for JavaScript 4.23 Slider since 4.12, effectiveMin added at 4.23.
When set, the user is restricted from moving slider thumbs to positions less than this value. This value should be greater than the slider min. The effectiveMin and effectiveMax allow you to represent ranges of values in a dataset that cannot be filtered or selected with the slider. This can be useful when using the slider to represent datasets with outliers, or scale ranges not suitable for a layer.
Example
// slider.min = 0
slider.effectiveMin = 4;
// now the user cannot slide thumbs below
// 4 even though the slider track displays
// values down to 0.Since: ArcGIS Maps SDK for JavaScript 4.23 Slider since 4.12, effectiveSegmentElements added at 4.23.
The HTML Element nodes representing the slider segment between the min and effectiveMin, and the segment between the effectiveMax and max. You can use this property to customize the style and attach event handlers to these segments. This only applies to sliders where the effectiveMin and effectiveMax are specified.
Example
slider.effectiveSegmentElements.forEach( segmentElement => segmentElement.classList.add("redLine") );Since: ArcGIS Maps SDK for JavaScript 4.27 Slider since 4.12, icon added at 4.27.
Icon displayed in the widget's button.
Inherited
Property id String
The unique ID assigned to the widget when the widget is created. If not set by the developer, it will default to the container ID, or if that is not present then it will be automatically generated.
A function that provides the developer with access to the input elements when rangeLabelInputsEnabled and/or labelInputsEnabled are set to true. This allows the developer to customize the input elements corresponding to slider min/max and thumb values to validate user input. For example, you can access input elements and customize them with type and pattern attributes.
Example
// Sets the slider thumb inputs as number inputs
slider.inputCreatedFunction = function(input, type, index){
input.setAttribute("type", "number");
input.setAttribute("pattern", "[0-9]*");
};A function used to format user inputs. As opposed to labelFormatFunction, which formats thumb labels, the inputFormatFunction formats thumb values in the input element when the user begins to edit them.
The image below demonstrates how slider input values resemble corresponding slider values by default and won't match the formatting set in labelFormatFunction.
If you want to format slider input values so they match thumb labels, you can pass the same function set in labelFormatFunction to inputFormatFunction for consistent formatting.
However, if an inputFormatFunction is specified, you must also write a corresponding inputParseFunction to parse user inputs to understandable slider values. In most cases, if you specify an inputFormatFunction, you should set the labelFormatFunction to the same value for consistency between labels and inputs.
This property overrides the default input formatter, which formats by calling toString() on the input value.
Example
// Formats the slider input to abbreviated numbers with units
// e.g. a thumb at position 1500 will render with an input label of 1.5k
slider.inputFormatFunction = function(value, type){
if(value >= 1000000){
return (value / 1000000).toPrecision(3) + "m"
}
if(value >= 100000){
return (value / 1000).toPrecision(3) + "k"
}
if(value >= 1000){
return (value / 1000).toPrecision(2) + "k"
}
return value.toFixed(0);
}Function used to parse slider inputs formatted by the inputFormatFunction. This property must be set if an inputFormatFunction is set. Otherwise the slider values will likely not update to their expected positions.
Overrides the default input parses, which is a parsed floating point number.
Example
// Parses the slider input (a string value) to a number value understandable to the slider
// This assumes the slider was already configured with an inputFormatFunction
// For example, if the input is 1.5k this function will parse
// it to a value of 1500
slider.inputParseFunction = function(value, type, index){
let charLength = value.length;
let valuePrefix = parseFloat(value.substring(0,charLength-1));
let finalChar = value.substring(charLength-1);
if(parseFloat(finalChar) >= 0){
return parseFloat(value);
}
if(finalChar === "k"){
return valuePrefix * 1000;
}
if(finalChar === "m"){
return valuePrefix * 1000000;
}
return value;
}The widget's default label. This label displays when it is used within another widget, such as the Expand or LayerList widgets.
Since: ArcGIS Maps SDK for JavaScript 4.20 Slider since 4.12, labelElements added at 4.20.
The HTML Element nodes representing labels attached to slider thumbs. You can use this property to customize the style of labels and attach event handlers to each element.
Example
slider.labelElements.forEach( labelElement => labelElement.classList.add("newStyle") );A function used to format labels. Overrides the default label formatter.
By default labels are formatted in the following way:
10 ((max - min) < 10), labels are rounded based on the value set in the precision property.10, labels display with a precision of no more than two decimal places, though actual slider thumb values will maintain the precision specified in precision.Use this property to override the behavior defined above.
Example
// For thumb values, rounds each label to whole numbers.
// Note the actual value of the thumb continues to be stored
// based on the indicated data `precision` despite this formatting
slider.labelFormatFunction = function(value, type) {
return (type === "value") ? value.toFixed(0) : value;
} labelInputsEnabled Boolean
Indicates whether to enable editing input values via keyboard input when the user clicks a label. This allows the user to move the slider thumb to precise values without sliding the thumbs.
Example
// allows the slider input label to be used for keyboard input
slider.labelInputsEnabled = true;An array of strings associated with 'values' generated using an internal label formatter or the values returned from labelFormatFunction.
Determines the layout/orientation of the Slider widget. By default, the slider will render horizontally with the min value on the left side of the track. The possible values are described below.
horizontal
horizontal-reversed
When the slider is set to horizontal-reversed, the max value will render on the left side and the min on the right.
vertical
When the slider is set to vertical, the max value will render on the top of the track and the min on the bottom.
vertical-reversed
When the slider is set to vertical-reversed, the max value will render on the bottom of the track and the min on the top.
Possible Values:"horizontal" |"horizontal-reversed" |"vertical" |"vertical-reversed"
Default Value:"horizontal"
Example
slider.layout = "vertical";The maximum possible data/thumb value of the slider. In the constructor, if one of the values specified in values is greater than the max value specified in this property, then the max will update to the highest value in values.
To display the max value's label on the slider, set visibleElements.rangeLabels to true. To allow the end user to modify the max value, set rangeLabelInputsEnabled to true.
Example
const slider = new Slider({
container: "sliderDiv",
min: 0,
max: 100,
values: [ 50 ]
});Since: ArcGIS Maps SDK for JavaScript 4.20 Slider since 4.12, maxLabelElement added at 4.20.
The HTML Element node representing the max value label. You can use this property to customize the style and attach event handlers.
Examples
slider.maxLabelElement.classList.add('maxClass');slider.maxLabelElement.addEventListener('click', () => {
slider.values = [ slider.max ];
});The minimum possible data/thumb value of the slider. In the constructor, if one of the values specified in values is less than the min value specified in this property, then the min will update to the lowest value in values.
To display the min value's label on the slider, set visibleElements.rangeLabels to true. To allow the end user to modify the min value, set rangeLabelInputsEnabled to true.
Example
const slider = new Slider({
container: "sliderDiv",
min: 0,
max: 100,
values: [ 50 ]
});Since: ArcGIS Maps SDK for JavaScript 4.20 Slider since 4.12, minLabelElement added at 4.20.
The HTML Element node representing the min value label. You can use this property to customize the style and attach event handlers.
Examples
slider.minLabelElement.classList.add('minClass');slider.minLabelElement.addEventListener('click', () => {
slider.values = [ slider.min ];
}); precision Number
Defines how slider thumb values should be rounded. This number indicates the number of decimal places slider thumb values should round to when they have been moved.
This value also indicates the precision of thumb labels when the data range is less than 10 (i.e. (max - min) < 10).
When the data range is larger than 10, labels display with a precision of no more than two decimal places, though actual slider thumb values will maintain the precision specified in this property.
For example, given the default precision of 4, and the following slider configuration, The labels of the thumbs will display two decimal places, but the precision of the actual thumb values will not be lost even when the user slides or moves the thumb.
const slider = new Slider({
min: 20,
max: 100, // data range of 80
values: [50.4331],
// thumb label will display 50.43
// thumb value will maintain precision, so
// value will remain at 50.4331
container: "sliderDiv"
});
If the user manually enters a value that has a higher precision than what's indicated by this property, the precision of that thumb value will be maintained until the thumb is moved by the user. At that point, the value will be rounded according to the indicated precision.
If thumb labels aren't visible, they must be enabled with labelInputsEnabled.
Keep in mind this property rounds thumb values and shouldn't be used exclusively for formatting purposes. To format thumb labels, use the labelFormatFunction property.
Example
rangeLabelInputsEnabled Boolean
Indicates whether to enable editing range values via keyboard input when the user clicks a min or max label. This allows the user to increase or decrease the data range of the slider.
Example
slider.rangeLabelInputsEnabled = false;Since: ArcGIS Maps SDK for JavaScript 4.20 Slider since 4.12, segmentElements added at 4.20.
The HTML Element nodes representing interactive slider segments. Segments are interactive when situated between two thumbs. You can use this property to customize the style and attach event handlers to segments.
Example
slider.segmentElements.forEach( segmentElement => segmentElement.classList.add("thickLine") ); snapOnClickEnabled Boolean
Indicates if the closest thumb will snap to the clicked location on the track.
Example
// disables snapping thumb values by click
slider.snapOnClickEnabled = false; state Stringreadonly
The current state of the widget.
Possible Values:"ready" |"disabled" |"editing" |"dragging"
Sets steps, or intervals, on the slider that restrict user input to specific values. If an array of numbers is passed to this property, the slider thumbs may only be moved to the positions specified in the array.
If a single number is set, then steps are set along the entire slider range at an interval of the provided value. In this scenario, the user may only slide the thumbs to values at the provided interval. For example, if a value of 0.5 is set here, and the slider min is 0 and the slider max is 10, then the user will only be able to update the thumbs to values of 0, 0.5, 1.0, 1.5, 2.0, etc.
Examples
// set steps at an interval of 0.5. So the
// slider thumb snaps at values of 0.5, 1.0, 1.5, etc.
slider.steps = 0.5;// Set steps at specific slider positions
slider.steps = [ 5, 10, 15, 20, 25, 30, 35, 40 ]; syncedSegmentsEnabled Boolean
Since: ArcGIS Maps SDK for JavaScript 4.20 Slider since 4.12, syncedSegmentsEnabled added at 4.20.
When true, all segments will sync together in updating thumb values when the user drags any segment. This maintains the interval between all thumbs when any segment is dragged. Only applicable when draggableSegmentsEnabled is true.
Example
slider.draggableSegmentsEnabled = true;
slider.syncedSegmentsEnabled = true;Function that executes each time a thumb is created on the slider. This can be used to add custom styling to each thumb or hook event listeners to specific thumbs.
Example
slider.thumbCreatedFunction = function(index, value, thumbElement) {
thumbElement.classList.add("change-color");
thumbElement.addEventListener("focus", function() {
// add custom behavior here...tooltips, fire other actions, etc.
});
});Since: ArcGIS Maps SDK for JavaScript 4.20 Slider since 4.12, thumbElements added at 4.20.
The HTML Element nodes representing slider thumbs. You can use this property to customize the style of thumbs and attach event handlers to each thumb.
Example
slider.thumbElements.forEach( thumbElement => thumbElement.classList.add("greenThumb") ); thumbsConstrained Boolean
When false, the user can freely move any slider thumb to any position along the track. By default, a thumb's position is constrained to the positions of neighboring thumbs so you cannot move one thumb past another. Set this property to false to disable this constraining behavior.
Example
// allows the user to freely move slider
// thumbs to any position along the track
slider.thumbsConstrained = false;When set, renders ticks along the slider track. See the TickConfig documentation for more information on how to configure tick placement, style, and behavior.
Examples
// places 25 ticks on the slider track
// evenly spaced from one another
slider.tickConfigs = [{
mode: "count",
values: 25
}];// places ticks spanning the width of
// the slider at 20% intervals from one another
// this is the equivalent of setting mode to 'count'
// and the values to 5.
slider.tickConfigs = [{
mode: "percent",
values: 20
}];// Places three ticks on the slider: one positioned
// 10% of the width from the start (or min value), another
// directly in the middle (50% from the start), and
// another 90% of the width from the start of the slider.
// Because the values are %s the values are always relative
// regardless of the range of the slider values.
slider.tickConfigs = [{
mode: "percent",
values: [ 10, 50, 90 ]
}];// Places 5 ticks on the slider at the slider values
// provided below. These are absolute positions.
slider.tickConfigs = [{
mode: "position",
values: [ 0, 5, 10, 15, 20 ]
}];// Places a single tick at the location of the value of 5.
slider.tickConfigs = [{
mode: "position",
values: 5
}];// Renders three groups of ticks. The first is a basic set
// of 25 ticks. The second places 4 ticks and adds custom
// CSS classes to modify their styling. The third adds
// a click event handler to the tick labels.
slider.tickConfigs = [{
mode: "count",
values: 25
}, {
mode: "percent",
values: [12.5, 37.5, 62.5, 87.5],

tickElement.style.cursor = "pointer";
labelElement.addEventListener("click", setValue);
labelElement.style.cursor = "pointer";
});The HTML Element node representing the slider track. Use this property to attach event listeners to the track or to customize the track's CSS.
Example
// Add CSS class to the track
slider.trackElement.classList.add("thickTrack");An array of numbers representing absolute thumb positions on the slider.
Example
const slider = new Slider({
min: 20,
max: 100, // data range of 80
values: [50.4331],
// thumb label will display 50.43
// thumb value will maintain precision, so
// value will remain at 50.4331

optionalThe HTMLElement representing the label of the thumb. You can add or modify the default style of the thumb's labels by adding CSS classes to this element. You can also add custom behavior to thumb labels by attaching event listeners to individual elements.
TickConfig
Object specification for configuring ticks on the slider. An array of these objects should be set on the tickConfigs property.
The mode or method of positioning ticks along the slider track. See the table below for a list of possible values.
Possible Value Description count Places a fixed number of ticks (provided in thevalues property) at equal distances from each other below the slider track. percent When set, and a single number is set on the values property, ticks will be placed at the specified percentage interval along the length of the slider. For example, when mode is percent and values is 5, then 20 ticks will be placed below the slider track (at 5-percent intervals from each other). If an array of values is provided, the values are interpreted as percentages along the slider. So if values is [10, 50, 90], then three ticks will be placed below the track; one at the midway point, and two 10 percent of the length from either end of the slider. position Indicates that ticks will only be placed at the values specified in the values property.
Possible Values:"percent"|"position"|"count"|"step"
values Number|Number[]Indicates where ticks will be rendered below the track. See the description for mode for more information about how this property is interpreted by each mode.
Indicates whether to render labels for the ticks.
tickCreatedFunction TickCreatedFunction optionalCallback that fires for each tick. You can override default behaviors and styles with this property.
labelFormatFunction LabelFormatter optionalCallback for formatting tick labels.
Examples
// places 25 ticks on the slider track
// evenly spaced from one another
slider.tickConfigs = [{
mode: "count",
values: 25
}];// places ticks spanning the width of
// the slider at 20% intervals from one another
// this is the equivalent of setting mode to 'count'
// and the values to 5.
slider.tickConfigs = [{
mode: "percent",
values: 20
