Question

是的，我知道“on”方法，这里关于“on”的大部分答案都不具体。有人可以帮我这个代码吗？

$(function(){

var pagePositon = 0,
    sectionsSeclector = 'article#sector',
    $scrollItems = $(sectionsSeclector),
    offsetTolorence = 30,
    pageMaxPosition = $scrollItems.length - 1;

//Map the sections:

$scrollItems.each(function(index,ele) { $(ele).attr("debog",index).data("pos",index); });

// Bind to scroll
$(window).bind('scroll',upPos);

//Move on click:
$(document).keypress(function(e) {
    if (e.which == 100 && pagePositon+1 <= pageMaxPosition) {
        pagePositon++;
        $('html, body').stop().animate({ 
              scrollTop: $scrollItems.eq(pagePositon).offset().top
        }, 300);
    }
    if (e.which == 97 && pagePositon-1 >= 0) {
        pagePositon--;
        $('html, body').stop().animate({ 
              scrollTop: $scrollItems.eq(pagePositon).offset().top
          }, 300);
        return false;
    }
});

//Update position func:
function upPos(){
   var fromTop = $(this).scrollTop();
   var $cur = null;
    $scrollItems.each(function(index,ele){
        if ($(ele).offset().top < fromTop + offsetTolorence) $cur = $(ele);
    });
   if ($cur != null && pagePositon != $cur.data('pos')) {
       pagePositon = $cur.data('pos');
   }                   
}
});

当你按“d”或“a”时，它会转到下一个或上一个id =“sector”，这很好。但偶尔，在Ajax Call之后和追加新文章后，脚本无法移动到它们。我知道他们没有绑定（在dom刷新之后）以及如何在Ajax dom更改后使该脚本工作？

解决了：

$(function(){

var pagePositon = 0,
    sectionsSeclector = 'article#sector',
    $scrollItems = $(sectionsSeclector),
    offsetTolorence = 30,
    pageMaxPosition = $scrollItems.length - 1;

//Map the sections:


// Bind to scroll


//Move on click:
$(document).on('keypress', function(e) {
    $scrollItems = $(sectionsSeclector);
    pageMaxPosition = $scrollItems.length - 1;
    $scrollItems.each(function(index,ele) { $(ele).attr("debog",index).data("pos",index); });

     $(window).bind('scroll',upPos);

    if (e.which == 100 && pagePositon+1 <= pageMaxPosition) {
        pagePositon++;
        $('html, body').stop().animate({ 
              scrollTop: $scrollItems.eq(pagePositon).offset().top
        }, 300);
    }
    if (e.which == 97 && pagePositon-1 >= 0) {
        pagePositon--;
        $('html, body').stop().animate({ 
              scrollTop: $scrollItems.eq(pagePositon).offset().top
          }, 300);
        return false;
    }
});

//Update position func:
function upPos(){
   var fromTop = $(this).scrollTop();
   var $cur = null;
    $scrollItems.each(function(index,ele){
        if ($(ele).offset().top < fromTop + offsetTolorence) $cur = $(ele);
    });
   if ($cur != null && pagePositon != $cur.data('pos')) {
       pagePositon = $cur.data('pos');
   }                   
}

}）;

如何在Ajax dom追加后使jquery脚本工作？
