We face a problem that input type range allow only one value to select. If we want to select two values from a range we have no option. we need to add two input type range slider to take input min value and max value. Handling two input range control is not easy and manages events is also very difficult.
For the solution of selecting multiple value and handling events it provide a solution. It allows user to select min value and max value from a range slider. It's design layout is fully controlled by CSS and provide a lot of events to handle via JavaScript.
How to Use
download MultiRangeSlider.js/MultiRangeSlider.min.js and include in your project.
There are two way to add this control on form
Method 1
let options ={container: document.querySelector('.container')};
let multiRangeSlider1 = new MultiRangeSlider(options);
Method 2
let multiRangeSlider2 = new MultiRangeSlider();
document.querySelector('.container').appendChild(multiRangeSlider2);
Options
This slider control can be handled by options that is passed to constructor function as explained in Method 1
let options = {
container : null, // target container element where it append
id : '', //set id attribute if passed value else unset
baseClassName : '', // prefix of class names of all elements of range slider default "multi-range-slider" set if you want to change theme style.
min : 0, // slider min value default is 0
max : 100, // slider max value default is 100
step : 5, // slider step value default is ((max - min) / 20)=5
value_min : 25, // slider selected min value default is ((max - min) * 0.25)
value_max : 75, // slider selected max value default is ((max - min) * 0.75)
showRuler : true, // is ruler visible or not default is true
showValue : true, // is selected min and max value label shows or not default true
showLabel : true, // is slider min and max value shows or not default true
preventWheel : false, // is slider move with mouse wheel default is false
oninit : null, // eventHandlerFunction trigger when control is created by constructor.
onbarclick : null, // eventHandlerFunction trigger when control's bar clicked.
oninput : null, // eventHandlerFunction trigger when control's value change by user.
onchange : null, // eventHandlerFunction trigger when control's value change by user or JavaScript.
onslidestart : null, // eventHandlerFunction trigger when thumb is start sliding by user.
onslide : null, // eventHandlerFunction triggers continuously till the thumb is sliding by user. also trigger when user click on bar.
onslideend : null // eventHandlerFunction trigger when thumb is stop sliding by user.
}
