我做了这个无限滚动的剧本，但我不能重新绑定窗口滚动后，我unbinded它。这里的脚本：

  $（函数（）{
    $（窗口）.scroll（函数（）{
        VAR mostOfTheWayDown =（$（文件）.height（） -  $（窗口）.height（））* 2/3;
        如果（$（窗口）.scrollTop（）＆GT; = mostOfTheWayDown）{
            $（窗口）.unbind（滚动）;
            $阿贾克斯（{
                网址：loadmore，
                数据：{lastrank：lastrank}，
                数据类型：JSON，
                键入：POST，
                成功：函数（JSON）{
                    //一些工作在这里
                    $（窗口）.bind（滚动）;
                }
            }）;
        }
    }）;
}）;
 

我怎样才能重新绑定窗口滚动一个成功的Ajax调用后？

解决方案

  $（函数（）{
    VAR scrollFunction =功能（）{
        VAR mostOfTheWayDown =（$（文件）.height（） -  $（窗口）.height（））* 2/3;
        如果（$（窗口）.scrollTop（）＆GT; = mostOfTheWayDown）{
            $（窗口）.unbind（滚动）;
            $阿贾克斯（{
                网址：loadmore
                数据：{lastrank：lastrank}，
                数据类型：JSON，
                键入：POST，
                成功：函数（JSON）{
                    //一些工作在这里

                    $（窗口）.scroll（scrollFunction）;
                }
            }）;
        }
    };
    $（窗口）.scroll（scrollFunction）;
}）;
 

I have made this infinitely scrolling script, but I can't rebind the window scroll after I unbinded it. Here's the script:

$(function(){
    $(window).scroll(function(){
        var mostOfTheWayDown = ($(document).height() - $(window).height()) * 2 / 3;
        if ($(window).scrollTop() >= mostOfTheWayDown) {
            $(window).unbind('scroll');
            $.ajax({
                url: 'loadmore',
                data: {lastrank: lastrank},
                dataType: 'json',
                type: 'POST',
                success: function(json){
                    //some work here
                    $(window).bind('scroll');
                }
            });
        }
    });
});​

How can I rebind the window scroll after a successful ajax call?

解决方案

$(function(){
    var scrollFunction = function(){
        var mostOfTheWayDown = ($(document).height() - $(window).height()) * 2 / 3;
        if ($(window).scrollTop() >= mostOfTheWayDown) {
            $(window).unbind("scroll");
            $.ajax({
                url: "loadmore",
                data: {lastrank: lastrank},
                dataType: "json",
                type: "POST",
                success: function(json){
                    //some work here

                    $(window).scroll(scrollFunction);
                }
            });
        }
    };
    $(window).scroll(scrollFunction);
});​
