解决方法
我认为这可以工作：
link_to "your link",href,:onclick => "jsFunction"
或者,做一切JS方面：
document.body.addEventListener('click',function(e)
{
var target = e.target || e.srcElement;
if (target.tagName.toLowerCase() !== 'a')
{
return e;//not clicked on link
}
//a link was clicked,maybe check class or id or other stuff to narrow it down
//if a link you were interested in was clicked:
return theClickFunction.apply(target,[e]);
},false);
