JavaScript/jQuery RangeSlider Options
See Also
accessKey
The value of this property will be passed to the accesskey attribute of the HTML element that underlies the UI component.
activeStateEnabled
The UI component switches to the active state when users press down the primary mouse button. When this property is set to true, the CSS rules for the active state apply. You can change these rules to customize the component.
Use this property when you display the component on a platform whose guidelines include the active state change for UI components.
elementAttr
Specifies the global attributes to be attached to the UI component's container element.
jQuery
$(function(){
$("#rangeSliderContainer").dxRangeSlider({
// ...
elementAttr: {
id: "elementId",

@NgModule({
declarations: [
AppComponent
],
imports: [
BrowserModule,
DxRangeSliderModule
],
providers: [ ],
bootstrap: [AppComponent]
})
export class AppModule { } Vue
<template>
<DxRangeSlider ...
@option-changed="handlePropertyChange"
/>
</template>
<script>
import 'devextreme/dist/css/dx.light.css';
import DxRangeSlider from 'devextreme-vue/range-slider';
export default {
components: {
DxRangeSlider
},
// ...
methods: {
handlePropertyChange: function(e) {
if(e.name === "changedProperty") {
// handle the property change here
}
}
}
}
</script> React
import React from 'react';
import 'devextreme/dist/css/dx.light.css';

const handlePropertyChange = (e) => {

rtlEnabled
When this property is set to true, the UI component text flows from right to left, and the layout of elements is reversed. To switch the entire application/site to the right-to-left representation, assign true to the rtlEnabled field of the object passed to the DevExpress.config(config) method.
DevExpress.config({
rtlEnabled: true
});startName
The value to be assigned to the name attribute of the underlying <input> element.
Specify this and endName properties if the UI component lies within an HTML form that will be submitted.
tabIndex
The value of this property will be passed to the tabindex attribute of the HTML element that underlies the UI component.
validationError
Information on the broken validation rule. Contains the first item from the validationErrors array.
validationMessageMode
Specifies how the message about the validation rules that are not satisfied by this editor's value is displayed.
validationMessagePosition
Specifies the position of a validation message relative to the component. The validation message describes the validation rules that this component's value does not satisfy.
The following example positions a validation message at the component's right:
jQuery
$(function() {
$("#rangeSliderContainer").dxRangeSlider({
// ...
validationMessagePosition: 'right'
}).dxValidator({
validationRules: [{
type: 'required',
message: 'Required',
}],
});
});Angular
<dx-range-slider ...
validationMessagePosition="right">
<dx-validator>
<dxi-validation-rule
type="required"
message="Required"
>
</dxi-validation-rule>
</dx-validator>
</dx-range-slider>Vue
<template>
<DxRangeSlider ...
validation-message-position="right"
>
<DxValidator>
<DxRequiredRule message="Required" />
</DxValidator>
</DxRangeSlider>
</template>
<script>
// ...
</script>React
import React from 'react';
// ...
function App() {
return (
<RangeSlider ...
validationMessagePosition="right"
>
<Validator>
<RequiredRule message="Required" />
</Validator>
</RangeSlider>
);
};
export default App;validationStatus
The following table illustrates the validation status indicators:
| validationStatus | Indicator |
|---|---|
"pending" |
 |
"valid" |
 |
"invalid" |
 |
When you assign "invalid" to validationStatus, you can also use the validationErrors array to set an error message as shown below:
jQuery
$(function() {
const rangeSlider = $("#rangeSliderContainer").dxRangeSlider({
// ...
}).dxRangeSlider("instance");
function setInvalidStatus(message) {
rangeSlider.option({
validationStatus: "invalid",
validationErrors: [{ message: message }]
});
}
});Angular
<dx-range-slider
[validationStatus]="validationStatus"
[validationErrors]="validationErrors">
</dx-range-slider>
// ...
export class AppComponent {
validationStatus: string = "valid";
validationErrors: any;
// ...
setInvalidStatus(message) {
this.validationStatus = "invalid";
this.validationErrors = [{ message: message }];
}
}Vue
<template>
<DxRangeSlider ...
:validation-status="validationStatus"
:validation-errors="validationErrors"
/>
</template>
<script>
// ...
export default {
// ...
data() {
return {
validationStatus: "valid",
validationErrors: []
}
},
methods: {
setInvalidStatus(message) {
this.validationStatus = "invalid";
this.validationErrors = [{ message: message }];
}
}
}
</script>React
import React, { useState } from 'react';
// ...
function App() {
const [validationStatus, setValidationStatus] = useState("valid");
const [validationErrors, setValidationErrors] = useState([]);
const setInvalidStatus = message => {
setValidationStatus("invalid");
setValidationErrors([{ message: message }]);
}
return (
<RangeSlider
validationStatus={validationStatus}
validationErrors={validationErrors}
/>
);
};
export default App;valueChangeMode
Specifies when to change the component's value.
If you want to change the component's value after a user releases the component's handle, set this property to onHandleRelease. The moment when the onValueChanged function is called depends on this property:
jQuery
$(function() {
$("#rangeSliderContainer").dxRangeSlider({
// ...
valueChangeMode: 'onHandleRelease',
onValueChanged: function (e) {
const previousValue = e.previousValue;
const newValue = e.value;
// Event handling commands go here
}
});
});Angular
<dx-range-slider
[(value)]="value"
valueChangeMode="onHandleRelease"
(onValueChanged)="handleValueChange($event)">
</dx-range-slider>
import { Component } from '@angular/core';
@Component({
selector: 'app-root',
templateUrl: './app.component.html',
styleUrls: ['./app.component.css']
})
export class AppComponent {
value = 25;
handleValueChange (e) {
const previousValue = e.previousValue;
const newValue = e.value;
// Event handling commands go here
};
}
import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';
import { AppComponent } from './app.component';
import { DxRangeSliderModule } from 'devextreme-angular';
@NgModule({
declarations: [

DxRangeSliderModule

providers: [ ],
bootstrap: [AppComponent]
})

export default {
components: {
DxRangeSlider
},
data() {
return {
value: 25
};
},
methods: {
handleValueChange(e) {
const previousValue = e.previousValue;
const newValue = e.value;
// Event handling commands go here
}
}
}
</script>React
import React, { useState, useCallback } from 'react';
import 'devextreme/dist/css/dx.light.css';
import { RangeSlider } from 'devextreme-react/range-slider';
function App () {
const [value, setValue] = useState(25);
const handleValueChange = useCallback((e) => {
const previousValue = e.previousValue;
const newValue = e.value;
// Event handling commands go here
setValue(newValue);
}, [value]);
render() {
return (
<RangeSlider
value={value}
valueChangeMode="onHandleRelease"
onValueChanged={handleValueChange}
/>
);
}
}

This property accepts a value of one of the following types:
Number
The width in pixels.String
