Jquery----关于Deferred的问题

[Chobohoo]

function getModelId(obj, dataTypeName) {


var def = $.Deferred();

$.ajax({
type: "GET",
contentType: "application/json; charset=utf-8",
datatype: "json",
url: “此处隐藏。。。。”,
beforeSend: function (XMLHttpRequest) {
XMLHttpRequest.setRequestHeader("OData-MaxVersion", "4.0");
XMLHttpRequest.setRequestHeader("OData-Version", "4.0");
XMLHttpRequest.setRequestHeader("Accept", "application/json");
XMLHttpRequest.setRequestHeader("Prefer", "odata.include-annotations=\"*\",odata.maxpagesize=1");
},
success: function (data, textStatus, xhr) {
var results = data;
if (results.value.length > 0) {
obj.ModelId = results.value[0]["productid"];
def.resolve(obj);
}
else {
def.reject("The " + dataTypeName + " data of Model " + modelName + " is not imported due to " + modelName + " is not exist.");
}

},
error: function (xhr, textStatus, errorThrown) {
def.reject("Error Info: " + textStatus + " " + errorThrown);
}
})

return def.promise();

}


刚刚接触Deferred对象，上面的写法，应该是有问题的，但不清楚问题出在哪里，还望大神们指教一下。谢谢

写法没看出来有什么问题，调用报错了吗，贴出来看看。
