我编写了自己的函数,该函数在滚动特定点后将边栏固定在屏幕上,然后在滚动回顶部时将其恢复到相对位置。如果将窗口的大小调整为小于边栏的高度,则它也将其返回到其正常的相对位置。很棒!

问题是,当我在页面正文的全景缩略图上运行另一个函数(即fancybox())并尝试滚动时,我原来的“ scroll-fix”函数似乎停止工作。

有人知道为什么吗?

“滚动固定”功能

 $(document).ready(function(){

  var element = $("#sidebar");
  var window_height = $(window).height();
  var element_height = element.height();

  $(window).ready(function() {
    if (window_height > element_height) {
      if (($(document).scrollTop() + element.height()) > ($(document).height() - $("#footer").height() - 9)) {
        element.css("position","absolute");
        element.css("top", "auto");
        element.css("bottom","-60px");
      }
      else if ($(document).scrollTop() > 220) {
        element.css("position","fixed");
        element.css("top","9px");
        element.css("padding-top","0");
        element.css("bottom","auto");
      }
      else {
        element.css("position","relative");
        element.css("top","auto");
        element.css("padding-top","57px");
        element.css("bottom","auto");
      }
    }

});

最佳答案

此代码的第一次更改不会产生相同的问题

(function($) {
    $.fn.myScrollFix = function(options) {

        options = $.extend({
            footer:  "footer",
            pthis: this,
            doc: $(document),
            win: $(window)
        }, options || {});

        options.footer = $(options.footer);
        options.accion = function() {

            var element = options.pthis,
                doc_scroll_top = options.doc.scrollTop(),
                doc_height  = options.doc.height(),
                window_height = options.win.height(),
                element_height = options.pthis.height(),
                footer_height = options.footer.height();

            if (window_height > element_height) {
                if ((doc_scroll_top + element_height) > (doc_height - footer_height - 9)) {
                    element
                        .css("position","absolute")
                        .css("top", "auto")
                        .css("bottom","-60px");
                }
                else if (doc_scroll_top > 220) {
                    element
                        .css("position","fixed")
                        .css("top","9px")
                        .css("padding-top","0")
                        .css("bottom","auto");
                }
                else {
                    element
                        .css("position","relative")
                        .css("top","auto")
                        .css("padding-top","57px")
                        .css("bottom","auto");
                }
            }
            else {
                element
                    .css("position","relative")
                    .css("top","auto")
                    .css("padding-top","57px")
                    .css("bottom","auto");
            }
        };

        $(window).bind("scroll", options.accion);
        $(window).bind("resize", options.accion);

        options.accion();
    };
})(jQuery);
$(document).ready(function(){
    $("#sidebar").myScrollFix();
});


然后您可以在FancyBox中修改这些行

432行

$(window).unbind("resize scroll", $.fn.fancybox.scrollBox);


439行

$(window).unbind("resize scroll", $.fn.fancybox.scrollBox);
