让回调函数 showResponse 也带上参数（转）

function demo(url,paras,updateElemID){
var myAjax = new Ajax.Request(
url,
{
method: 'post',
parameters: paras,
onComplete:function(originalRequest){showResponse(originalRequest,updateElemID)}
});
}
function showResponse(originalRequest,elemID){
var html = originalRequest.responseText;
$(elemID).innerHTML = html;
}
