我无法弄清楚如何将函数分配给 Dojo 中的滚动事件。我已经看过关于使用 dojo 连接的另一篇文章，但我一直无法让它工作，即使我可以，我的项目也尽可能多地使用行为，所以我真的想先让它工作...

对我来说令人费解的是，我在 dojo 的网站上浏览了一下，而我看到的滚动事件的唯一参考只是将它们作为旁白提及。以http://dojotoolkit.org/reference-guide/1.9/quickstart/events.html#connecting-to-a-dom-event为例，有一个可以连接的事件列表，并且滚动是不在他们身上。鼠标滚轮向上 + 向下是，但这并不涵盖可能导致滚动发生的所有可能操作。

我以前使用过 jQuery 的滚动事件，这很简单。我在解决 Dojo 中的滚动事件时遇到了这么多麻烦，这让我有点困扰。

这是我尝试过的：

var myBehavior = {
    window : {
    scroll: function(e) {
        console.log("i'm scrolling");
        }
    }
    };
behavior.add(myBehavior);
behavior.apply();

加载没有任何问题，但滚动不会给我控制台日志消息。

我也试过

dojo.connect(window,'scroll',this,function() {
        console.log("scrolling away");
    })

我几乎是从链接的帖子中得到的，我也没有收到控制台日志消息。我开始怀疑我是否缺少密钥库？

我要求的那些我认为是多余的： - dojo/_base/lang - dojo/query - dojo/_base/event - dojo/on - dojo/behaviour - dojo/window

有人对我如何开始在 Dojo 中注册这些滚动事件有建议吗？谢谢

我创建了一个jsfiddle 来演示窗口滚动事件的用法dojo/on。

Does your lorem ipsum text long for something a little meatier? Give our generator a try… it’s tasty!
    </div>
</body>

js：

require(['dojo/on','dojo/domReady!'],function(on,domReadyPlugin){

    on(window,'scroll',function(evt){
        console.log(evt);

    });
});

每次用户在窗口中滚动时，结果都会打印到控制台。如果您仍然遇到问题，请发布更多代码以便我们深入了解它，这应该是一件简单的事情。

使用“onscroll”而不是“scroll”，看到这个 jsfiddle

dojo.connect(window,'onscroll',this,function() {
        console.log("scrolling away");
    })
