避免从onclick事件（原型）重置浏览器

Question

I have few anchors with a click event:

$$('.someanchor').invoke('observe', 'click', somefunction );

When the anchor is clicked, the browser scrolls to top. I tried to insert return false at the end of somefunction , but it still scrolls up.

Usually I would use something like:

Event.observe('somelement', 'click', somefunction, false);

But this doesnt work for a collection of elements. So how do I return false from a invoke statement?

Answer 1

在somefunction ，在函数主体的末尾添加以下内容（确保e是最后一个参数，并且用于Event对象）：

e.preventDefault();

Answer 2

"e.preventDefault()" prevents the anchor default behavior but not the event propagation (bubbling). I would use "Event.stop(event)" to neutralize both, just for being on the safe side.
