我试图为以下场景找到一些解决方案:
- 页眉高度完全不同
- 鼠标向下滚动
- 固定 header
有谁知道如何制作多个这样的粘性标题？
(1) 初始化
(2) 向下滚动(使用鼠标)
(3) 向下滚动(使用鼠标)
最佳答案
嗯...
$(window).scroll(function() {
var $headers = $(".header");
var scrollTop = $(this).scrollTop();
if (scrollTop <= 0) {
// reset all
$headers.css({
position: "relative",
top: "0px"
});
} else {
$headers.each(function(index, $el) {
var $curHeader = $($headers).eq(index);
var curTop = $curHeader.offset().top;
var curHeight = $curHeader.height();
// scroll up
var isRelative = ($el.isFixed && scrollTop <= $el.exTop);
// scroll down
var isFixed = (curTop <= scrollTop);
var position = "";
var top = 0;
if (isRelative) {
// reset
positon = "relative";
top = 0;
$el.isFixed = false;
} else if (isFixed) {
position = "fixed";
if (0 < index) {
for (var i = 0; i < index; i++) {
top += $($headers).eq(i).height();
}
}
scrollTop += curHeight;
if (!$el.isFixed) {
$el.isFixed = true;
$el.exTop = curTop;
}
}
$($el).css({
position: position,
top: top + "px"
});
});
}
});body {
height: 10000px;
}
div {
height: 200px;
background: gray;
width: 100%;
}
.header {
height: 50px;
background: green;
}
div.header:nth-child(7) {
height: 100px;
