$("#cattype").change(function(){
var catid = $(this).val(); //获取切换的类别的id

$.getJSON('getCate',{catid:catid},function(data){
$('#catchild option[value!=""]').remove(); //清空option 每次改变option的时候载入新的数据
//alert(data.length);
if(catid==''){
vals="";
$(vals).appendTo("#catchild");
}else{
for(var i=0;i var vals='';
vals+="";
$(vals).appendTo("#catchild");
}
}
