Manual Download

Download from the GitHub repository and include the desired version from the build/ directory:

Configuration

HTML Structure

Create the required DOM structure:

        <li>...</li>
        <li>...</li>
        ...
    </ul>
</div>

CSS Requirements

Add positioning to the wrapper:

#wrapper {
    position: relative;
    overflow: hidden;
}

JavaScript Initialization

Initialize iScroll when the DOM is ready:

<script type="text/javascript">
var myScroll = new IScroll('#wrapper');
</script>

Configuration Options

You can pass options during initialization:

var myScroll = new IScroll('#wrapper', {
    scrollY: true,              // Enable vertical scrolling
    scrollX: false,             // Disable horizontal scrolling
    mouseWheel: true,           // Enable mouse wheel scrolling
    scrollbars: true,           // Enable scrollbars
    fadeScrollbars: true,       // Fade scrollbars when not in use
    interactiveScrollbars: true // Enable scrollbar dragging
});

Troubleshooting

Common Issues

1. Scroll not working

Problem: iScroll doesn't initialize properly Solution: Ensure DOM is ready and wrapper has position: relative or absolute

window.addEventListener('load', function() {
    var myScroll = new IScroll('#wrapper');
});

2. Performance issues on mobile

Problem: Laggy scrolling with many elements Solution: Keep DOM simple, avoid complex CSS properties

/* Avoid these for better performance */
#wrapper * {
    box-shadow: none;
    opacity: 1;
    text-shadow: none;
}

3. Scroll position wrong

Problem: Scroller size is incorrect Solution: Ensure images have explicit dimensions or use onBeforeScrollStart event

var myScroll = new IScroll('#wrapper', {
    onBeforeScrollStart: function(e) {
        var target = e.target;
        while (target.nodeType != 1) target = target.parentNode;
        if (target.tagName != 'SELECT' && target.tagName != 'INPUT' && target.tagName != 'TEXTAREA')
            e.preventDefault();
    }
});

4. Scrollbars not showing

Problem: Scrollbars are disabled or not visible Solution: Enable scrollbars in options

var myScroll = new IScroll('#wrapper', {
    scrollbars: true,
    fadeScrollbars: true
});

5. Touch events not working

Problem: Touch scrolling disabled on some devices Solution: Check touch event options

var myScroll = new IScroll('#wrapper', {
    disableTouch: false,  // Enable touch
    disablePointer: true, // Disable pointer events if not needed
    disableMouse: false   // Enable mouse events
});

Debug Mode

Enable debug mode to see console messages:

var myScroll = new IScroll('#wrapper', {
    debug: true
});
