script.aculo.us Sliders range Option
  • Last Updated : 27 Nov, 2020

The script.aculo.us library is a cross-browser library that aims at improving the user interface of a website. The Slider controls are thin tracks that allow the user to input values. It is done by defining a range of values that can be selected by the user by dragging the handle to the appropriate value.

The Sliders range is used to define the range of the slider. The slider handle can only move within the value defined for both ends. The range has to be specified using $R(min, max) syntax, where min denotes the minimum value of the slider and max denotes the maximum value.

Syntax:

{ range: $R( min, max ) }

Values: This option has two values as mentioned above and described below:

  • min: This is a number that denotes the minimum value of the range of the slider.
  • max: This is a number that denotes the maximum value of the range of the slider.

Example:






<!DOCTYPE html>
<html>
<head>
  <!-- Include the required scripts -->
  <script type="text/javascript" 
          src="prototype.js">
  </script>
  <script type="text/javascript"
          src="scriptaculous.js?load = slider">
  </script>
  
  <!-- Style the Sliders so that they
  are properly visible -->
  <style type="text/css">
    .track {
      width: 200px;
      background-color: gray;
      height: 5px;
      position: relative;
    }
