jquery 中post 、get的同步问题

$.ajaxSetup({
async : false
});

$.get("register/RegisterState", {test : 12}, function(data, status) {
if (status == "success") {
data = eval("(" + data + ")");
aDataSet = data;
alert("data is " + aDataSet);
} else {
alert("wrong");
}
});

$.ajax({
type : "post",
url : "register/RegisterState",
data : "test=" + test,
async : false,
success : function(data){
data = eval("(" + data + ")");
aDataSet = data;
}
});
