最后代码里面的keyup是从哪里来的
addEvent("search_input","keyup" function(){
getDOM(search-suggest).style.top=getElementTop(getDOM(search-form))+38+'px';
getDOM(search-suggest).style.left=getElementLeft(getDOM(search-form))+'px';
getDOM(search-suggest).style.position="absolute";
getDOM(search-suggest).style.display="none";
});
