jqueryui刚用，不熟，我的目标是一个autocomplete选择一个值后，后面的combobox自动下拉里面有值，现在autocomplete功能已实现，combobox死磕没搞出来，请高手给指点，所有的数据均为远程取得，在线等，谢谢，combobox的参考资料好像不太多哦，呵呵，谢谢了，分不多，50分仅表示本人的诚意，对于您提供的帮助，非常感谢！

我猜你想要实现的是选择普通AutoComplete控件下拉列表的选项时 将这一项添加到后边的ComboBox下拉菜单中去.
如果你不是要实现这种效果,你得详细解释下"后面的combobox自动下拉里面有值"这句话.
你需要的代码在191行中文注释下方,有问题请追问.

我的意思是combobox里的数据是通过前面那个autocomplete的结果，然后从数据库中查出来的
主要combobox那段，给段远程取得数据的代码参考一下，谢谢！

假设你使用java-servlet实现的后台查询,URL是"yourUrl.action",接受一个叫label的参数,查询到数据后给页面返回一个JSON字符串,格式为[{'label':xxx,'value':xxx},.....]这样子的话,那你在AutoComplete的select事件中这样写
select: function( event, ui ) {
var label=ui.item.label,value=ui.item.value;
//清空Combobox
$( "#combobox" ).empty();
/**此处传递上面的参数进行查询,获得远程数据*/
//假设你用java-servlet实现的后台功能,
$.ajax({
url:"yourUrl.action",
data:{'label':label},
type:'POST',
dataType:'json',
success:function(data){
if(data && data.length>0){
for(var index=0;index<data.length;index++){
//将选项添加到comboBox中
$( "#combobox" ).append($('<option>').attr('value',data[i].value).html(data[i].label));
}
}
}
}
