Question 1

How do I make iScroll work on mobile devices?

Accepted Answer

Initialize iScroll with options like disableMouse and disablePointer for touch-only devices, ensure the wrapper has position:relative, and load it on window onload for correct dimensions. Use the tap event for click handling instead of native clicks.

Question 2

iScroll vs native scrolling: which is better for performance?

Accepted Answer

iScroll can offer smoother, customizable scrolling on older browsers and devices where native scrolling is janky, but it adds JavaScript overhead. On modern browsers with good native support, iScroll might be unnecessary unless you need advanced features like snap or parallax.

Question 3

Why is my iScroll stuttering or laggy?

Accepted Answer

Common causes include using CSS properties like box-shadow or opacity that hinder hardware acceleration, having too many elements in the scroller, or not enabling HWCompositing. The README advises experimenting with CSS and adjusting options like useTransition.

Question 4

How to implement parallax scrolling with iScroll?

Accepted Answer

Use the indicators option to create multiple layers that follow the main scroller at different speed ratios. Set ignoreBoundaries and adjust speedRatioX/Y for each indicator to achieve the parallax effect, as shown in the demos.

Question 5

Can I use iScroll with React or Vue.js?

Accepted Answer

Yes, but it requires manual integration since iScroll is a vanilla JS library. You'll need to initialize and manage the iScroll instance in lifecycle methods, handle DOM updates with refresh(), and bind events carefully to avoid conflicts with the framework's virtual DOM.

Question 6

How to refresh iScroll after loading content dynamically?

Accepted Answer

Call the refresh() method after DOM updates, typically inside a setTimeout with 0ms delay to ensure the browser has repainted. For complex changes, increase the timeout to 100-200ms for better reliability.

Question 7

What's the difference between iscroll.js and iscroll-lite.js?

Accepted Answer

iscroll.js includes all standard features like snap, scrollbars, and mouse wheel, while iscroll-lite.js strips these down to basic scrolling for minimal footprint and maximum performance on mobile, but lacks advanced functionality.
