调用不同的jQuery函数时，jQuery函数似乎退出

问题描述

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！

I wrote my own function that keeps a sidebar fixed on screen after a certain point of scrolling and then returns it to it's relative position when scrolled back to the top. If the window is resized to a size smaller then the height of the sidebar, it returns it to its normal relative position as well. Works great!

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.

Problem is when I run another function, namely fancybox(), on the panoramic thumbnail in the body of the page, and try scrolling, my original "scroll-fix" function seems to stop working.

有人知道这是为什么吗?

Anyone know why this is?

此代码的首次更改不会产生相同的问题

first changes for this code to not generate the same problems

(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

then you can modify these lines in FancyBox

第432行

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

第439行

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