为什么每个按钮只能工作一次？

Question

我正在尝试为我创建的一些flash横幅创建div导航。我编写的代码按升序排列，但是一旦你点击过去的代码，你就无法回到它。如何使其像导航一样，可以按任何顺序重复点击每个标题，它会起作用？

    });
});

function nextPage(to, type){ 
var to = $(to),
    from = $("#allPages .current");

to
.addClass("current " + type + " in")
.one("webkitAnimationEnd msAnimationEnd animationend oAnimationEnd", function(){
  from.removeClass("current " + type + " out" );
  to.removeClass(type + " in");
});
from.addClass(type + " out ");
}

在将current类添加到下一页之前，您需要从from页面中删除它。 from.removeClass()将完成这项工作：

function nextPage(to, type) {
    var to = $(to),
        from = $("#allPages .current");

    from.removeClass();
    to.addClass("current " + type + " in").one("webkitAnimationEnd msAnimationEnd animationend oAnimationEnd", function () {
        from.removeClass("current " + type + " out");
        to.removeClass(type + " in");
    });
    from.addClass(type + " out ");
}
