使用Dojo的行为功能来识别滚动事件
我不知道如何在Dojo中将函数分配给滚动事件。我看过这个关于使用dojo的连接的other post，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……
令我困惑的是，我在dojo的网站上浏览了一下，我所看到的滚动事件的唯一参考资料只是将它们作为附注。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，而scroll不在它们上面。鼠标滚轮向上和向下是一样的，但这并不包括可能导致滚动发生的所有可能的操作。
我以前使用过jQuery的scroll事件，这很好也很简单。我在处理Dojo中的scroll事件时遇到了这么多麻烦，这一事实让我有点困扰。
这是我尝试过的：
var myBehavior = {
window : {
scroll: function(e) {
console.log("i'm scrolling");
}
}
};
behavior.add(myBehavior);
behavior.apply();加载时没有任何问题，但是滚动不会给出控制台日志消息。
我也试过
dojo.connect(window,'scroll',this,function() {
console.log("scrolling away");
})我很大程度上是从链接的文章中得到的，我也没有得到控制台日志消息。我开始怀疑我是不是遗漏了密钥库？
- dojo/_base/lang - dojo/query - dojo/_base/event - dojo/on - dojo/behaviour dojo/window
对于如何开始在Dojo中注册这些滚动事件，有人有什么建议吗？谢谢

我为窗口滚动事件创建了一个演示dojo/on用法的jsfiddle。

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。如果你仍然有问题，张贴更多的代码，以便我们可以找到它的底部，这应该是一件简单的事情。

使用"onscroll“而不是"scroll"，参见this jsfiddle
dojo.connect(window,'onscroll',this,function() {
console.log("scrolling away");
})https://stackoverflow.com/questions/19209724
