jQuery 页面根据鼠标位置上下滚动
jQuery page up and down scroll based on mouse position
$(document).ready(function() {
var mouseX;
var mouseY;
$(document).mousemove(function(e) {
mouseX = e.pageX;
mouseY = e.pageY;
});
$("#maincontainer").mousemove(function() {
// $('#DivToShow').css({'top':mouseY,'left':mouseX}).fadeIn('slow');
$('#DivToShow').html("Y " + mouseY + " --- " + "X " + mouseX);
if (mouseY > 230) {
$('html, body').animate({
scrollBottom: $elem.height()
}, 800);
}
});
});
请帮忙,我正在尝试根据指针位置自动上下滚动页面。当指针到达浏览器底部时,页面需要向下滚动 60px ++。没有一个滚动到页面末尾。
试试这个解决方案。
在 mousemove 上,获取 clientY 和 window 高度。如果相差小于60,则比当前scrollTop多滚动60:
$(document).on('mousemove', function(e) {
var y = e.clientY;
var h = $(window).height();
var n = h - y;
if (n < 60) {
var t = parseFloat($(window).scrollTop());
console.log(t);
$('html,body').animate({scrollTop:t + 60 + 'px'},200);
} else {
$('html,body').stop();
}
});
#wrapper,
.section {
width:100%;
float:left;
}
.section {
height:80px;
border:1px solid #ccc;
}
