Introduction
RollBar is a jQuery plugin that enables you to add a responsive scrollbar to your web pages, providing a better user experience, especially on devices with touch screens or limited screen real estate. It's designed to be highly customizable, allowing you to tailor the scrollbar's appearance and behavior to fit your specific needs.
In this tutorial, we'll take a step-by-step look at how to use RollBar, covering installation, basic usage, and customization options.
Step 1: Installation
To use RollBar, you'll need to include the jQuery library and the RollBar plugin in your HTML file. You can include the files from a CDN or download them and host them on your own server.
Here's an example of how to include the files using a CDN:
<head>
<script src="https://code.jquery.com/jquery-3.6.0.min.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery-scrollbars/1.1.0/jquery.scrollbar.min.js"></script>
</head>Step 2: Basic Usage
Once you've included the RollBar plugin, you can activate it on a HTML element using the .scrollbar() method. Here's an example:
$(document).ready(function() {
$('#myDiv').scrollbar();
});In this example, #myDiv is the ID of the HTML element that you want to apply the scrollbar to.
Step 3: Customization
RollBar offers a range of customization options, allowing you to tailor the scrollbar's appearance and behavior to fit your specific needs. Here are a few examples:
Appearance
You can change the scrollbar's appearance using the following options:
theme: Sets the theme of the scrollbar. You can choose from one of the built-in themes or create your own. (Default:classic)color: Sets the color of the scrollbar. You can use a hex code or a CSS color name. (Default:#ccc)width: Sets the width of the scrollbar. You can specify a pixel value or a percentage. (Default:12px)height: Sets the height of the scrollbar. You can specify a pixel value or a percentage. (Default:16px)
Here's an example of how to set the theme and color:
$(document).ready(function() {
$('#myDiv').scrollbar({
theme: 'dark',
color: '#f00'
});
});Behavior
You can change the scrollbar's behavior using the following options:
enableTouch: Enables or disables touch scrolling. (Default:true)enableMouseWheel: Enables or disables mouse wheel scrolling. (Default:true)dragThreshold: Sets the threshold for dragging the scrollbar. You can specify a pixel value or a percentage. (Default:5)
Here's an example of how to enable touch scrolling and set the drag threshold:
$(document).ready(function() {
$('#myDiv').scrollbar({
enableTouch: true,
dragThreshold: 10
});
});Events
RollBar also provides a range of events that you can bind to, allowing you to react to changes in the scrollbar's state. Here are a few examples:
scroll: Fired when the user scrolls the scrollbar.resize: Fired when the user resizes the scrollbar.dragStart: Fired when the user starts dragging the scrollbar.dragEnd: Fired when the user stops dragging the scrollbar.
Here's an example of how to bind to the scroll event:
$(document).ready(function() {
$('#myDiv').scrollbar().on('scroll', function(event) {
console.log('Scrolled!');
});
});That's it! With these basic steps and customization options, you should be able to get started with using RollBar on your web pages.
overflowY
The overflowY setting determines if the scrollbar should be active when the content is bigger than the container in the vertical direction. By default it's set to auto, which means the scrollbar will be active when there is a need for one.
$('#my-scrollbar').rollbar({
overflowY: true // or false, or 'auto'
});overflowX
The overflowX setting determines if the scrollbar should be active when the content is bigger than the container in the horizontal direction. By default it's set to false, which means the horizontal scrollbar will not be displayed unless it's necessary (e.g. when container is too small).
$('#my-scrollbar').rollbar({
overflowX: true // or false
});theme
You can customize the appearance of the scrollbar by using predefined themes or creating your own. You can use this setting to specify the name of the theme you want to use.
$('#my-scrollbar').rollbar({
theme: 'dark'
}); // or 'light'scrollThickness
The scrollThickness setting determines the height of the scrollbar. If you want to make it thicker or thinner, just set this value.
$('#my-scrollbar').rollbar({
scrollThickness: 16 // default is 16
});scrollBorderRadius
This setting determines the border-radius of the scrollbar. The default value is 8.
$('#my-scrollbar').rollbar({
scrollBorderRadius: 10 // can be any value
});scrollSliderBorderRadius
This setting determines the border-radius of the scroll slider. The default value is Infinity, which means no corners will be rounded.
$('#my-scrollbar').rollbar({
scrollSliderBorderRadius: 5 // can be any value
