我试图为以下场景找到一些解决方案:
1.顶盖高度完全不同
1.鼠标向下滚动
1.固定标头
有人知道如何像这样制作多个粘头吗?
(1)初始化

(2)向下滚动(使用鼠标)

(3)向下滚动(使用鼠标)

$(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;

下面是一个简单的例子:
我正在计算标头的高度并设置top属性。

    • 一个
$(window).scroll(function () {
var $headers = $(".header");
if ($(this).scrollTop() > 50) {
    $headers.each(function (index, el) {
        var height = 0;
        if (index == 0) {
            height = "0px";
        } else {
            for ( var x = index - 1; x >= 0; x--) {
                height += $headers.eq(x).height();
            }
        }
        height = height + "px";
        $(el).css({
            "position": "fixed",
                "top": height
        });
    });
} else {
    $headers.css({
        position: "relative",
        top: "0"
    });
}
});
body {
  height: 10000px;
}
div {
  height: 100px;
  background: green;
  width: 100%;
}

.header {
  height: 50px;
  background: red;
}
.header:first-child {
  height: 20px;
}
div.header:nth-child(5) {
  height: 100px;
}
