無緩存，無錯版
$.ajax({
?? type: "GET",
?? url: "index.php",
?? cache: false,
?? data: "con=Add&act=_search&key=" + key+"&id="+id,
?? dataType:"json",
?? success: function(msg){
?? bindGroupList(msg);
?? }
});

//綁定
function bindGroupList(result)
{
?? var eles = document.forms['theForm'].elements;
?? eles['group_id'].length = 1;
?? for (i = 0; i < result.content.length; i++)
?? {
???? var opt = document.createElement('OPTION');
???? opt.value = result.content[i].id;
???? opt.text? = result.content[i].name;
???? eles['group_id'].options.add(opt);
?? }
}

會緩存
$.getJSON("?con=Add&act=_search&key=" + key+"&id="+id, function(data){
??? //bindGroupList(data)
});
