问题描述
基本上,功能就在这里,它只需要一些改进,我不知道如何调整,我已经编写了这个小片段,完全符合我的需求,但是并没有滚动整个页面,它只是滚动窗口"的大小.
Basically, the functionality is here, it just needs some refinement that I don't know how to tweak, I've written this small snippet that does exactly what I want, but doesn't scroll the whole page, it just scrolls the "window" size.
任何人都可以接受它并使其变得惊人吗? :)
Can anyone take this and make it amazing? :)
$(document).mousemove(function(e){
percent = ((e.pageY) * 100) / $(this).height();
$('body,html').scrollTop( percent);
});
推荐答案
您可能希望有一个增量,具体取决于鼠标相对于页面中央的偏移量:
You may rather want to have a delta depending on how far the offset of mouse is with respect to the middle of the page: http://jsfiddle.net/BYUdS/2/. That way, you can keep scrolling down so that there is no scroll limit (what you have now).
$(document).mousemove(function(e) {
$("html, body").scrollTop(function(i, v) {
var h = $(window).height();
var y = e.clientY - h / 2;
return v + y * 0.1;
});
});
这是一个更平滑的版本: http://jsfiddle.net/BYUdS/3/
var $elems = $("html, body");
var delta = 0;
$(document).on("mousemove", function(e) {
var h = $(window).height();
var y = e.clientY - h / 2;
delta = y * 0.1;
});
$(window).on("blur mouseleave", function() {
delta = 0;
});
(function f() {
if(delta) {
$elems.scrollTop(function(i, v) {
return v + delta;
});
}
webkitRequestAnimationFrame(f);
})();
