这个问题我没有思路，大家给指点一下。

Question

在ajax成功返回值后再进行循环，当然，你最好贴一下你代码

Answer 1

function change_user_address(obj)
{
var value;
value=obj.value;
Ajax.call('user.php?act=select_address',"consignee="+value,change_user_addressResponse,"POST","JSON");}
function change_user_addressResponse(result)
{
document.address.consignee.value=result['consignee'];
document.address.email.value    =result['email'];
document.address.address.value  =result['address'];
document.address.zipcode.value  =result['zipcode']; var country,province,city,district;
country =result['country'];
province =result['province'];
city =result['city'];
district =result['district'];
var c_province=document.address.province.options.length;for(i=0;i<c_province;i++)
{
if(document.address.province.options[i].value==province)
{
document.address.province.options[i].selected=true;
document.address.province.options[i].selectedIndex=-1;
document.address.province.onchange(); 
break; 
}
}alert(1);var c_city=document.address.city.options.length;for(i=0;i<c_city;i++)
{
if(document.address.city.options[i].value==city)
{


document.address.city.options[i].selected=true;
document.address.city.options[i].selectedIndex=-1;
document.address.city.onchange(); 
break; 

}
}alert(2);
var c_district=document.address.district.options.length;
for(i=0;i<c_city;i++)
{
if(document.address.district.options[i].value==district)
{
document.address.district.options[i].selected=true; }
}
