注：由于本人主要做后台的就只用到了IO空间下面的一些东西，贴个小小的级联效果来吧，
废话少说先拿代码说话了，
复制代码 代码如下:
Demo.show={
Test:function(e,Y)
{

function onshengchange(e)
{

var years = Y.Node.get('#'+config.years);
var timeslist =Y.Node.get('#'+config.times);
var content="<option selected=selected>请选择</option>";
speccode.setContent("<option selected=selected>加载数据....</option>");
years.setContent(content);
timeslist.setContent(content);
var requestSpeciality = Y.io("Test.aspx", {
method:"POST",
data:"type=sheng&sheng="+sheng,
