fireEvent
摘自果果的js库：
function addEvent(el,type,fn,capture){
if(el.addEventListener){
el.addEventListener(type,fn,capture);
}else if(el.attachEvent){
el.attachEvent('on'+type,function(){
fn.call(el);
});
}else{
el['on'+type] = fn;
}
}
function fireEvent(el,type){
if(document.createEventObject){
return el.fireEvent('on'+type);
}else{
var e = document.createEvent('HTMLEvents');
e.initEvent(type,true,true);
return !el.dispatchEvent(e);
}
}
var a = document.getElementById('a'),b = document.getElementById('b');
addEvent(a,'click',function(){alert('a has been clicked')});
addEvent(a,'mouseover',function(){alert('mouseover')});
addEvent(b,'click',function(){fireEvent(a,'click')});
