This article is about several patterns of scroll events in js. The editor thinks it is very practical, so share it with you as a reference and follow the editor to have a look.

The event occurs on the window object, but it actually represents a change in the corresponding element in the page:

1. Hybrid mode: monitor this change through scrollleft and scrolltop.

2. Standard mode: reflect this change through elements (except that Safari,Safari is still based on tracking scrolling positions).

Example

EventUtil.addHandler (window, "scroll", function (event) {if (document.compatMode = = "CSS1Compat") {/ / alert (document.documentElement.scrollTop) in standard mode;} else {alert (document.body.scrollTop);}}); Thank you for reading!
